- In this video, we show you the different ways that Vacuum manufactures mislead you with specsmanship to "prove" to you that their vacuum is best. We then compare several top name vacs, running them through the same same Inches of water vacuum meter to prove relative to each other, which vacuum has the best suction We answer the question which vacuum Has Best Suction? Shop Vac, Ridgid, Dyson, or Milwaukee.

I use the size 1 and 1/0 Mustad hooks to freeline for snook czcams.com/users/postUgkxzXmlErSqVAEGWFEKO530BvTqFDw53QW3 and they have been fantastic. The points are super sharp, and the hook is small enough to blend with my baitfish, yet large enough to land fish 30" or more. I also use these hooks when I'm pier or surf fishing with my kids. They tend to catch tons of smaller snapper, whiting, and catfish, and we get far fewer gut hooks with these Mustad in-lines, which means more of them survive after release. I was actually using these hooks when I caught my friend too, but I think that had more to do with the bait I was using ;-)

I love it! Great video comparison.
thanks John, glad you liked it!
Another great video! Love your insight! One of my favorites. VCG and your channel I watch constantly! Thanks again and looking forward to your next video!
Awesome Robert glad to see you're here watching our videos common Vince and the gang they put out some really good videos to I love their tool test raws
I cant describe how helpful this video is thanks a lot. Very intuitive and well described!
Glad you enjoyed it!
Glad you thought of this. I was looking at reviews of the Milwaukee m18 and no one came close to showing a good comparison. This cleared up any concerns I have. Thank you so much sir! Great video.
Glad I could help
Very informative video! Thanks Jeff!
Thanks for watching Mike, glad to help out!
Thank you, great demonstration!
Glad it was helpful!
Great job, great information
Thanks Shiwei!
The diameter of the tube (ââŠone inch tubeâŠâ) is irrelevant in measuring pressure. Inches of water is how high the water can be lifted by the vacuum. The unattainable max would be equivalent to 1 atmosphere, or about 14.7 psia. That is, the height that the water can be raised up from a reservoir that is open to atmosphere. The weight of the water in the tube is its volume x density. The volume is height x area of the tube. The vacuum pressure is force x area. The area factors cancel out, leaving only the height of the water.
One atmosphere is about 14.7 psia, which is about 398.1 inches of water.
Awesome review! âđżđ
Thank you đ€ Chris, glad you liked it
Nicely done đ
Thank you đ
"the FORCE is strong with this one" đ€Ł
Always!
CFM is all that really matters in most applications. Want to clean up dust or use your vac as a dust collector -CFM. Want to vacuum a carpet, pick up construction debris, pull dust off the ceiling fan- CFM. What to pick empty a swimming pool maybe vacuum pressure assuming it still has decent CFM at that pressure.
Good idea
Good video I liked the comparision and variety of vacuums you tested. I have to add that inches of water or the suction you are measuring is only part of the story you do have to consider the CFM. If you have a pile of sawdust a higher CFM vacuum with the same suction pressure will suck that pile down faster for sure. I equate it to my truck in the torque and horsepower ratings you need both. Like others commented excellent video quality!
Thanks Ryan!
Hi Jeff,
I scored on a milwaukee gen2 cordless vacuum on Craigslist for only $50.00. The gentleman was moving over to UK and didn't want to ship it. Only used twice and the thing looks brand new.
I already have large ah batteries and rapid charger. SWEEEEEET!!
Thanks for the video
Wow that is a good deal. I should have checked in our local CR as well, but then I was doing videos and tool hauls from the stores....
@@jeffostroff
Yes, you're a busy man. When you have some time look at Craigslist.
You might catch a deal once in a while.
Again, thanks for all the videos you put out. I catch some good deals at Lowe's and Home Depot.
Excellent video
Thank you very much!
I have a question that has nothing to do with this video so Iâm hoping someone can help. I have a new Maytag Bravos XL top loading washing machine, previously an LG front loader, and I am experiencing drain line overflow. I extended the stand pipe which helped for a few months but it overflowed again after a large load. I think I want to put a y connector with a one way valve on one side and sealing the drain line from the washer into the other side. My understanding is the valve will allow air in since I am sealing the drain line into the other side. I did snake the line and there was noting blocking the line, I cleaned out the drain before the standpipe so I canât figure why this is happening other than the faster rate and increase of water volume from the new washer. FYI, the standpipe is a 2 inch pipe and plenty high enough but not too high per reading about the proper height. Thanks in advance for any help with this issue
Tom, I am wondering if you are missing the required vent stack or if your current vent stack is clogged. As you know, all our drain lines to the sewer should also be connected to vertical vent stacks (pipes) that go up through the ceiling, through the roof and vent to the outside so we can get air behind water and the water will drain properly, and plumbing codes require every drain pipe to be vented to the plumbing stack. There should be no excuse as to your drain pipe not handling the water from the washing machine. So do you know you have a vent stack there rising to the roof? If you can get up to the roof, see if it's clogged, spider webs, dead critters, leaves, etc anything blocking the air flow. Also, here are 2 paragraphs of plumbing code from here in FL, to give you an idea of similar requirements: 802.3.3 Standpipes
... Standpipes shall be individually trapped. Standpipes shall extend not less than 18 inches (457 mm) but not greater than 42 inches (1066 mm) above the trap weir. Access shall be provided to standpipes and drains for rodding. AND ALSO from Ch 10: 1002.1 Fixture traps
Each plumbing fixture shall be separately trapped by a liquid-seal trap, except as otherwise permitted by this code. The vertical distance from the fixture outlet to the trap weir shall not exceed 24 inches (610 mm), and the horizontal distance shall not exceed 30 inches (610 mm) measured from the centerline of the fixture outlet to the centerline of the inlet of the trap. The height of a clothes washer standpipe above a trap shall conform to Section 802.3.3. A fixture shall not be double trapped.
Truth is, they both matter. Measuring just the lift just tell you how hard they can suck, not how much flow they have. It would be like measuring power just by measuring amperes and ignoring voltage.
Good point
An interesting thing to think of. If you only choose your vaccuum acording to inches of water, you would probably walk home from home depot with a vacuum pump, that doesent mean it will be good at vacuuming. The pressure different with a certain air flow would be interesting in this type of study.
If only I had the same test equipment the vac manufacturers use
Love the Dyson's suction power! Wish they made a shop vac. My DC17 is still going strong. Keep up the apples-to-apples comparisons!
I would love to see a Dyson Shop Vac
awesome vid
Thanks Mario
The Dyson looks like it could suck the hair of my dog or cat. Great test. Thanks for showing real performance numbers.
Yes, when you keep the rolling brush clean and don't let the cylinder get overstuffed, this Dyson is like a tornado
What are your thoughts about using the dyson with a dust deputy to keep the canister clean for shop tool dust collection vs a shop vac since its suction was so much better?
Blue tape, always known for its pressure sealing properties...
It worked here, does not take much to seal it.
what would you recommend to use in a dusty house in this list of vacuums, dyson dco7 caught my eye but i want to know which other vacuum would be great
I just bought the Dyson V11 Animal + vac, but have not opened it yet, hope to do a tool review on it soon. this one is battery operated. Costco normally has it at $579, but I waited and every few months they lower it to $479 or $439, and I caught it on a $439 cycle.
What cam do you use for your vids? great vids.
Thanks, I use a new Nikon Z6 camera that I bought last may for $2300, very expensive pro gear, but worth every penny. The lens i used on this is a second lens, a 50 mm f1.8 lens that cost $600 on top of the camera. I bought it because that f1.8 aperture is what allows me to make the background blow up out of focus while only the important subject matter in the frame are in focus. Gives a professional movie or documentary feel to it.
great video and very useful info. they have digital manometer to measure static pressure ( inches of water column)
One of these days I might look into 1 of those if I do another test run of different vacuums
Amazon has a cheap version
I'm curious, what video equipment did you use to record this video?? It looks "movie-like" (for the lack of a better term)
Nikon Z6 camera, but the cinematic look is called boceh, which was supplied by my $600 Z6 50mm f1.8 lens, that lens makes all the difference in the world.
In my experience, CFM and Inches of Vacuum go together in determining how well a vacuum cleaner works. A larger diameter hose on a machine with a higher CFM rating will clean up a mess faster than one with a smaller hose and lower CFM rating.
yes good insight!
We've used the ridgid 4 gallons at work for about 10 years. They have good power and have taken many beatings.
I love the 4-gallon vac, the large rear wheel rolls over extension cords better than the joke casters on the the 16 gallon
I had a Rigid wet/dry vac for over 18 years that gave me great service.. I burned it up on a bad outlet circuit that could not provide enough amperage and voltage.. Went and bought a shop vac that lasted no more than 2 weeks before the motor died.. Went straight to HD and picked up another Rigid like the one in the video.. Has lasted me a good year and a half so far, and may get another 20 yrs out of it.. Wish you would have also tested a Shark against that Dyson..
holy shit, I've never seen your channel before, but what camera are you shooting with? looks amazing.
Glad you noticed, I shoot 4k resolution videos with my Nikon Z6
Great test, per value the $39 blackfriday deal was probably the best... Hopefully we can see you test the Ryobi 2gal and the Ridgid 18v new one out as well, thanks again! (And then theres the sit down on value, only see one capable of that!)
Yes I would like to do the battle of the cordless vacs get them all lined up the wall no logging ryobi rigid makita even Hart if they make one
"Like a bad marriage!" Lol
Thanks, I'm glad you liked it!
Thanks so much for the education! I need a stronger portable for around the house (not the handhelds). Can you recommend a good sucker for around the house? That's how I dust :)
My Milwaukee M18 has been a great one because you don't need top plug it in. But the 4 gallon Ridgid is my goto on my remodeling projects.
Easy to use and set up.
I like my 4 hP Ridgid best
I want a vacuum that pulls in a lot of air and with a lot of force. Anything much less than 100 inches of water and 100 CFM just feels wimpy to me. But I'm also a spoiled vacuum collector and I've gotten used to more powerful machines. You usually want as much or more air flow as you have sealed vacuum for fastest filth inhalation.
My god the Dyson looks to be in amazing condition, the bin it not that cloudy and the motor sounds really good too
Yes we have always done a good job of emptying the bin out I wash it out once in a while we always kept that vacuum pretty clean
@@jeffostroff well color me surprised people actually do take care of their vacuums other than collectors like myself and the fact that itâs a dyson, all the dysons I did for work were in terrible condition
I love my dyson but when I have had things break they gave me the run around still got parts on my own and fixed it but in the process they have a big filter inside you have to take stuff apart to get to. It surrounded the motor assembly. This makes me wonder how many of the other vacs do too. This test was awesome to see. I do have to add you can have high vac with low air volume and it wont pick stuff up. Cfm is more important that you let on :p but when you pushing down on something trying to get embedded dirt need that vac power so both are important.
Yes, that raw suction power, and no clogged filters.
High suction with low CFM would only work if you're trying to pick something up with a straw. High CFM with low suction could suck up a lot of light things.
Right on about cfm and inches of water. The vac gauge measures static pressure which is not a good indicator of effectiveness. Best to go with cfm. A small vac with low cfm can have the same static pressure as a vac with a higher cfm but be less effective. This as a bogus test so is peak hp.
I need a vac for my table saw. I already own a Dyson. Can I just hook that up to my saw with an in-line bucket/dust separator & get similar if not better results than any of these units?
I prefer using either the 4.5 gallon Ridgid or the 10 gallon, some pros prefer to use the Dewalt dust extractors, but they can be quite costly.
Cool video! Have you tried this with Dyson's battery powered units? They begin to pulse when there's a restriction. I don't see an easy way to test.
I have a V11 Animal plus that we are preparing to test
@@jeffostroff I never saw your video with the V11. I'm still interested in it. I got my own gauge, and my V7 pulses at 70. I'm not sure how impressed I'm supposed to be, but I'm a little impressed.
I have that exact same yellow Dyson vacuum. Still works great after more than 10 years, but the handle broke and Dyson won't sell me spare parts.
Let me know if/when you plan to dispose of that vacuum. i'd like to have that handle part from you.
Have you tried eBay? Lots of people sell appliances for parts only
I used a Dyson house vacuum once. It had some kind of relief valve which would open if you block the hose (e.g. cover it with your hand). When the valve opens, I'm certain the water-inches gauge would drop. I wonder how it could be tested...?
They probably use a special jig in their test lab for that.
@@jeffostroff unlike u, failing to creat seal with your bare hands.
This vid would b great, if u measure properly. It's useless as is.
Unfortunately, by your logic, the hand pump I use to inflate/deflate pool toys should do a magnificent job cleaning my shop because it can probably easily exceed 100 inches of suction. However, because it doesnât have the air flow (CFM), it wonât vacuum at all. You MUST consider BOTH suction pressure and air flow. This is flawed and as misleading as the HP printed on those vacuums. :-(
What is misleading is that your hand pump could exceed 100" of suction
Okay, but both flow rate and pressure do matter. A vacuum pump doesnât make a good vacuum cleaner.
I just purchased a Shop-Vac because it is made in the USA.
That's a good reason
Thanks for this video it really brings to light some falsehoods in shop vacs. I think the Tyson does so well because it probably had tight seals. I would be curious to see how well the vacs would work if you improve the seal on the lid.
It's all mind boggling. At the end of the day, the way we use it in real life without sealing the end of the hose is what matters.
Nope! Th Dyson has such small hose that it has to move less air to get the same PSI. Same for their newer models. The hose easily get clogged a lot. This never happens on my 2.5" hosed shop vac. I have an older one that has smaller hose and it is often getting blocked so I never use it anymore.
to toriless, this test doesn't pass any air so the size of the tank and hose doesn't matter if nothing leaks. A measurement of suction while air and material are moving would be a better test but the test results would be a function of what was being vacuumed and how. A series of tests under different conditions with one simulating your use would be a useful guide.
@@mervmurphy5691 The tank does not matter but the hose width does, it is basic physics, why do you think a nozzle can spray water 20 feet but it will just drizzle out the end of the hose a few feet. Look up how PSI or resistance works.
Would be interesting to see results from Festool and Fein. The problem with a lot of cheap vacuums is that they are loud and have cheap power cords.
Yes, I want to do a SPL sound test one day comparing all of them.
I replace the cords with top notch 25 ft versions.
I wish some one did this for household vacuums
forget the old, buy a new cordless vac! Good sales this coming week at Costco on the LG CordZero will be $130 off starting 3/10
I have a problem with the way you tested the suction power of each vacuum. First of all, each hose end must have an âair-tightâ seal to your vacuum gauge. The shop vac obviously did not have a good seal. Blue painters tape should not be used to adjust the fit of each hose. The length of each vacuum hose will also make a big difference. The dyson did not have any hose. How do you vacuum a car floor mat with the dyson ?
interesting test....would love to see you do the test without the filters because you would take them out if you was gonna suck up water....that may be why the dyson showed good results I think you said it was bag less.
Dyson also has a filter, so who knows how different it would be. I hope to review the Dyson V11 Animal+ in a few weeks.
What vacuum gauge are you using. I have looked for it on amazon but cant find one that goes past 30. Maybe its because yours says inches of water and most are inches of mercury?
Inches of water is the standard it was made by OCI
Are you sure thatâs inches of water, not mercury? A vacuum cannot exceed negative one atmosphere, or -398.08 inches of water or 28.8 inches of mercury.
You know I'm all over your channel. My girlfriend bought me that same small rigid portable vac. Haven't used it yet but she was listening before Christmas cuz u said that would be perfect for auto detail work. How have you liked it so far? I don't plan to use the bag. It came with a regular filter like your 16 gallon version, it also came with the bag you're showing in the video. I think it's a perfect size for most every day stuff especially if you're focused on little scraps out of a vehicle.
Philip I love the vacuum and many times I use it without the bag because I think you might get a little bit more suction. The only times that the bag I think is absolutely necessary is when you're doing drywall dust because you really do want to capture all of that dust
@@jeffostroff well I was just strolling through home depot looking for the rigid auto detail kit for the vac and the kit was marked down to $20 from $40. So I bought the last two available. Figured it won't hurt to hoard one extra box for spare parts in case any accessory happens to fail me down the road. Also when checking out it rang up at regular price but I explained that the price was leveled half off and she simply adjusted it to the said price. Not sure what's going on there but andamn good score for anyone in the rigid line looking for a better longer hose and better attachments.
@@jeffostroff oh yea kit # VT2534
Can you review the 12 gallon shop vacuum
I need to do that one soon, yes!
No fair! You TAPED up the Dyson! Smh. Good video though
Yes, it was too flimsy and would not hold on its own.
I would want volume to be a major player. If you had 60 in of vacuum at one cubic feet per minute.....
.... That would only be useful for picking up a bowling ball with a suction cup attachment on it, but with a two and a quarter inch hose you wouldn't be able to pick a leaf off the floor.
Stanley SL18402-8B, 8 Gal. 6.0-Peak HP Stainless
Great suction powerđ
Yes, 6 HP is good
Its all about the warranty lifetime you got me
I hate short warranties
Yooo that dayson tho.
2003? Damm imagine New ones
We have the new Dyson V11+ Animal
The Milwaukee m18 works great for sucking up water
Yes, did you see our full tool review of the M18 Vacuum? czcams.com/video/5HJx5xTm6Hc/video.html We showed it sucking up perfectly 2 gallons as advertised.
Which one had the most suction? I'm confused.
The age and wear of the used ones may have given them a disadvantage, vs the advantage the new ones have with no wear, especially when drywall dust has been run through them?
NO< that probably has not affected them. DID You notice my 3 year old Ridged 4 gallon outperformed the brand new Rigid 16 gallon that had not been used yet?
@@jeffostroff that should say something for us old fellers.
What is your opinion on a dry / wet shop vac?
All of those vacs except the Dyson are wet/dry, I love them. I use them to vacuum up spilled water or empty out toilets before changing them out.
Hi Guys!!! Why isn't there a rubber gasket around the lip of most wet/dry vacuum drums? Wouldn't that improve suction? Have a great week everybody!!! :-)
What is best to clean you car and garage. Do you like detachable blowers
for garage I sweep up all big chunks, then use my DeWalt leaf blower to blow all the rest of dirt and dust out the garage and onto grass. Vacuum any dirt you see left, but usually there is none after the blower, I use the vac mainly in the corners behind bikes, tools, etc.
Someone needs to ask the consumer what they hate about their shop vac. Let me design a vacuum! I use a roll around vac that wonât roll over itâs own cord. Use soft wheels. Lower the center of gravity by moving the motor to the bottom. The electric cord must be attached at the bottom to eliminate tipping when pulling the cord. Let me store the hose and tubes on the vacuum itself in a height that rolls under a table or knee hole in a cabinet. Make a place for all the attachments. Not that wimpy flimsy plastic kind I find today. Then, and not last, design a cartridge filter that can be quickly cleaned by putting the hose on the âblowâ side and drop the cartridge into the trash can. There is more, but Iâm astonished that no one has tackled these simple issues. Câmon guys, designers, get to it. Iâll help!
Man you hit the nail right on the head with that one I want to vacuum that won't roll over its own cord pain in the butt You got a lot of good ideas there. Will call it the âMA Terminator â
Amen. I agree.
Interesting an industrial vacuum condenser off of a steam turbine pulls around 3" of mercury , the vacuums pull 41 " of water which is about the same, so your vacuum is as powerful as a 8 MWh turbine genset condenser.
Dang, I'm going to rewire it to power my house!
The difference is in the volume. These vacuums are achieving this lift with NO volume. I'm willing to bet that there is a LOT of CFM flowing through those turbine generators!
Vac master beast. Next
So you like them?
Powerful suction means little if you don't have the cfm. With little air flow, stuff just doesn't get sucked up into the hose. I would look for good cfm per hose size and good water column in ".
that is correct
You should always have a dry use filter when you use a bag incase it blows up
I order the cheapie bags off ebay and amazon, and yes they do tear up a lot.
So you acknowledge that air watts exists and then you ignore it for peak vacuum. The reason air watts exists is that your vacuum is likely never operating in pure vacuum mode unless you are trying to drain a pool (large or small). For instance I could take a vacuum pump capable of way more in/water but it would be a terrible vacuum cleaner. Thus air watts is a measurement of suction flow, not vacuum. Kind of similar to the relationship between torque and horsepower (the real kind not the bull crap vac makers stamp on).
i only ignore it because it's cerebral for most people, they want to see something finite that can imagine with their brain, or see it in action. that's why I used that inches of water vacuum meter, because you can put it on all of them and relatively see how they perform at a glance.
@@jeffostroff So in other words people are just to stupid to understand a very simple concept of air watts. If there under 40 I guess I agree with you.
@@tazblink Yes, that's why infomercials over the years avoid science, and show vacuums sucking up huge amounts of sand off the carpet. Or piles of stuff that no normal vacuum would ever pick up.
Did you clean the dysons filter prior to the text?
No, just ran it as is
jeffostroff it may preform better with a clean filter though.
@@Ca31_Buff It might but I tested all of the tools as is which is the condition that most people will be using their tools in most people don't operate with a brand new filter
jeffostroff well, as a vacuum collector. I clean my filters when they are dirty or starting to block airflow. Every 2-3 uses mine get a deep clean because the power has dropped from its brand new state. Iâm not normal in anyway when it comes to vacuums.
no need. in a static lift test, there is no flow volume. The pressure between the motor and hose end will equalize. It just takes a fraction of a second longer, if there is a stuffed filter. A dirty filter impedes air flow volume, not pressure in a static test.
Just to point out, a bagless vacuum like a dyson loses suction over time. To fix that you need to completely disassemble and clean the unit. Not as easy as changing a bag. If you're looking for a better vacuum look at a bagged Miele vacuum.
I agree everything what you say in this video. However cfm (airflow) is way more important than suction. For example many big shop vacs have high airflow, but low suction. That's what you want. Dyson has high suction, but poor airflow so it's not really suitable for woodworking jobs. I have anemometer to measure the airflow and suction gauge. I have noticed that airflow is way more important. But thanks for very well made test :)
Just bought an anemometer and used it on my DeWalt fan review couple of weeks ago.
Inches of water is only a small part of what is needed to move dirt. A tiny lab vacuum pump will exceed what these cleaners will do but won't clean the shop. To move dirt you need velocity at the nozzle. This needs lots of moving air (CFM) supported by enough drop in pressure (inches of water). If you took that Dyson, with all it's suction and put a large floor nozzle on it, it could not lift the amount of dirt that one of the larger wet dry units could.
Yes, you almost need to be an engineer to decide which vac to use for each cleaning chore.
You should redo the test and tape every one of them not just the Tyson that's not a fair comparison.
something is not quite right about your claim that CFM is not important, especially for a vacuum that has a large opening at the end of the hose. By having a large opening at the end, you severely reduce the suction pressure, which your test instrument does not measure, since the instrument itself has a fixed opening. Having a large CFM will allow the suction pressure to stay more consistent when the opening at the end of the hose is larger. A large CFM will allow you to maintain a high suction pressure over a larger area.
Do one on the 6.5hp please
sounds like a good idea.
I have an older 6.5 contractor shop vac in stainless and it is the best vac I've ever had in suction performance regardless of numbers.
I wish Dyson made a shop vac, so I won't need to have a shop vac and a bucket.
Maybe one day they will, I would love to see one.
I wish you had a powerflite pf51 in the mix. I bought one about 6 years ago for around the garage use. Itâs really strong
Yes, that PF51 has 114 CFM and 100" water lift according to the company, would really liked to have seen how it compare sin these tests. I'm sure my water lift gauge is not going to show the same results as the manufacturer, but I sense The Force is strong with this one.
Very informative, but the gauge tick marks move by 4, so many of your numbers are off...
thanks for watching
I have 2 upright vacs, a Kirby (4.5 amp) and a Hoover (12 amp). The Kirby far out sucks the Hoover! Why? Who knows.
Is suction reduced with increased hose diameter?
In theory the suction might be reduced, however with the bigger hose sizes that usually make the vacuum motor bigger so it sucks in with more power
"CFM" and "static pressure" are a part of the calculation but if your really interested in what the vacuum can do right at the attachment you also need to look at air velocity! A vacuums ability to pull a vacuum is pointless if you can't move any air. A vacuum pump can pull 29"-Hg vacuum which converts to 394" of water column but it won't clean your floor worth a damn. The other things that should be taking into consideration is the length and diameter of the hose being used.
Yes, when you put on those thinner attachments on the end of the hose you can hear the pressure increase
Inches of water is measured at 0 cfm, so not useful on its own.
What matters is airwatts, which accounts for both CFM and in. of H2O.
The formula is airwatts P=0.117354*CFM*in. H2O, and is maximum somewhere near the middle of the CFM and suction range.
To me none of the spcs matter. At the endof the day does it pick up my dirt? That's bottom line, because they all lie and misrepresent their power
I like it all but you really used painters tape for this?
Not that it really matters but I hate painters tape lol
I have aluminum foil tape now, I'll use that on the next one.
Lmao we got the same house vacđ
nice vac
@@jeffostroff its as old as me lol
You are measuring peak vacuum and not flow. CFM and vacuum should both be taken into account. A mityvac hand pump may be able to pull 30 inches of mercury and a bathroom fan may intake 150cfm but neither will clean your floor.
Still trying to figure what the optimal CFM is to vacuum your floor. I have an anemometer now, and may revisit the CFM airflow on these vacs.
Lol this was a joke and the punchline was the blue tape
whatever stops the flow of air. laugh all you want it worked
Good comparison using that vacuum pressure meter but horrible presentation not knowing what the hash marks interpret to during the making of the video. Also, I hope he learned the heart of the rigid motor doesn't live inside the filter. Actually, none of the motor is inside the filter and I believe it's even removable from the rest of the lid. Informative videos are great, when they have accurate info.
Yes, during filming I was misreading the hashmarks, I thought they were 2 per mark, but it turned out to be per mark, so I adjusted it in the text overlays. s far as the motor, you did not pay attention to the video, so eager to point out my faults so your criticisms are great when they have accurate info. If you look at 13:35 you'll see my hand point to the black part of the housing and I said the motor is inside here, then I said it's inside the circumference of the filter which is correct, I did not say it is inside the filter, somehow you took that to mean it's inside the filter, i was showing the size of the motor and where it is located so we can compare it to the other vac. All that is inside the filter is the plastic frame for the filter to slide over.
4 inches of lift per mark.
Better question....Why the hell does Shop-Vac keep changing colors?!
Because new owners maybe
Flawed premise. Can't look at water lift alone, CFM does matter. That's why Air Watts, which factors in both with a VERY SIMPLE calculation, is the better indicator of a vacuum's ability.
That's the stuff for scientists to debate, not homeowners, because they often mislead about where the CFM measurement is taken from.
ridgid for the win
I love both my Ridgids
Just got the small 4 gal WD4070 Ridgid⊠pretty sweet little bugger! I had a DeWalt DVX04T just before but took it back as it died less than a month after I bought itâŠ
So Dyson is first then the rigdid
Dyson is not practical for a construction site
i get the premise, but.... i couldn't watch after the painters tape to seal the gauge.
What would you use?
@@jeffostroff electrical, at least. i've made many a makeshift gaskets with electrical tape. we used to use electrical tape to seal vacuum de-gassers at a shifty manufacturing plant i used to work at. the best is to find appropriate attachments, especially for testing
Why did you test the Dyson outdoors itâs not an outdoor vacuum cleaner
Just as a sanity check to see how much suction power it has compared to the others. Who says you can't use it outdoors?
jeffostroff it says do not use outdoors or on wet surfaces
The anime vac bro wtf are you talkin about, what is wet there
Lmao run it's a dyson employee looking to void your warranty :p
Actually this really isnât a fair test because each vacuum you are testing has a different diameter hose or tube, obviously the larger diameter will have less pull giving less reading because itâs pulling larger space of air while the smaller diameter will show higher reading because it has to work less, itâs just like putting your hand at the end of the vacuum hose, the more you cover the vacuum will increase, now if all the devices you are testing had the same diameter hose that would be more fair. Peace and God Bless
this was not meant to be a fair test. This was meant to measure the vacuum that each of my machines puts out. Also diameter of the hose is only one parameter, there's the amount of airflow too.
The test measures water column inches of draw. One inch of water column is equal to a pressure of approximately 1/28 pound per square inch (psi). Stating this another way, a column water 28-inches high produces pressure that is equal to 1 psi. A larger tank and hose will provide more square inches but will not change the pressure per square inch, which is the significant factor.
I don't want too much static suction because it can stall out the vacuum head. My Ridgid portable vac is my best vacuum in my experience
I'm happy with both the Ridgids
A Rule of thumb. You can only get 3 hp max from 120 volt without capacitors
That's true, with or without capacitors. If you have a 100% efficient motor, with a perfect 100% power factor, you could get 3.2 Hp from a 120 volt, 20 amp outlet, without blowing the fuse or tripping a breaker. No motor is that efficient, though, capacitors can correct power factor, to get you as close as possible to that theoretical limit. There's a lot of creative math in marketing.
OT You background outdoor scene is strange, it looks unreal almost like youâre a miniature.
IT is just the shadowbox fence
Hey whereâs my shop vac cart that I built
That old big shop vac was crapping out on me so I bought this newer rigid back and ended up selling the whole thing on craigslist To make Room for the newer big rigid back that I bought at black Friday
jeffostroff Iâm gonna finally get my own âbig boyâ shop vac plus a few other tools
I think the sound effects on every transition is a bit overkill
I don't so that anymore
As a semiconductor manufacturing professional working on ion implantation equipment that typically operates at greater than 1 x 10e-8 torr (high or ultra high vacuum) using Turbo molecular and Cryogenic pumps, I had to cringe watching your "vacuum testing" procedures! I mean I can get water to boil at -90 deg F in high vac. But having said that, I'll give you a B+ for at least attempting to give a truer meaning to vacuum suction of shop vacs to your viewers! Nice try!
Yes this was not meant to be a lab result, this was not even the proper test equipment, since they actually use real tubes measuring the rise of water.
