- Dustbuster doesn't hold a charge? Hand Vac failing to work right? Watch as I hack into a Dustbuster to diagnose the problem and then answer 2 questions. Should I fix it AND/OR what can be salvaged for use as FREE project parts in a future electronics project? Often a battery failing to hold a charge is the main problem in a hand vac, Dustbuster or similar device but I like to make sure before I decide how I want to proceed.
In this Dialed In DIY video (DID) I carefully & completely take apart a Black & Decker Dustbuster to see what is inside and to answer the 2 key questions about fixing it or salvaging it for free parts. You can take the same approach with similar rechargeable devices too.
I found that the battery was the problem and it could easily be replaced if I wanted to. I also found that it was fun hacking the wiring and experimenting with the primary motor. It gave me some fun project ideas!
If you like getting FREE parts for your projects, then check out my playlist of "What's Inside" videos. I not only show how I take things apart & what I salvage but I also talk about where I get some of my stuff for free.
WARNING: working on electronics carries certain risks. If you deconstruct an appliance like this, then you are doing so at your own risk. While I mention some safety considerations in the video you really need to do your own research to ensure that you are fully informed and comfortable with what you are doing. Choose the safety techniques that work best for you.

Good video but I think the REAL reason the poster decided to use the vacuum as parts and not replace the battery is because putting it back together is far harder than taking it apart. Mine had a motor problem. I ended up taking apart the motor and replacing the front end bronze bushing. I made it from parts taken from a salvaged motor. In truth .... a replacement battery is almost 75% the cost of a new unit.
So true about replacement cost to buy the new battery. That was the main reason it went to salvage... I've started making my own replacemant packs for some things using salvaged cells. Thank you for taking the time to watch and comment!
Thanks for the great video. I've had one of these forever and it has a same battery issue. I'll see if it will worth to purchase a new battery versus buying a new vsccum. Thanks again!
Thank you very much for the kind words. I appreciate the view and the comment! Best of luck with the vacuum.
I found a nimh pattery pack for these but the best price was $38. That motor draws about 12 amps and runs scary fast at over 28000 rpm's. A new lithium powered vacuum cleaner is about $46. The circuit board is only for charging the batteries. An option would be to replace the nicads with 4 LION 16850 cells, but then a special charger is needed and it becomes complicated.
Very cool idea and info! Great user name too BTW. Thanks for taking the time to watch and comment... I really appreciate it!
Obsession of the Month in on in
Thanks for this great rundown. I have a hand vac with a 7,4 Li-Ion battery and a 7 W / 40 Watt motor. It works fine but too weak for my taste. Can I just install a more powerful motor from the store? What do you recommend I consider?
That sounds like a great idea. As long as there is space for a more powerful motor inside the case & the battery you have is enough to power it, then I think trading up on the motor will work perfect. My preference is to "salvage" parts where possible (its more fun for me that way for some strange reason) and a thrift store type of place could be a great start for finding a "broken" mini vac that could provide you with a better motor (for less money than buying a new motor). But, in the absence of that you can search on line for sites that sell used parts which can also be allot less expensive. Please let me know if I didn't really answer your question. I'd also love to hear how it turns out if you do upscale the motor. Thanks for your question and for watching my video!
Neat. But you stopped short of removing the fan from the motor, which is what I need to do without destroying either the fan or the motor. Thanks for posting.
After cleaning out all the dust! The noise level one through the ceiling is there a way I can quiet it back down? I clean two of these and both, gave me the same results. Super noisy! Any insight how I might be able to make them quite again?
I have cordless vacuum cleaner. It's motor 7.2v dc. And it is working from rechargeable battery 7.2v dc 1500mAh. When I start the vacuum it's speed is going slow after few seconds. I know this battery is faulty. But I don't want to buy battery. I want to use power supply adapter AC to DC. Input 220v ac, Output dc v as per the motor. Which adapter suitable for this motor? Which adapter i should buy? What is the amp of 220v ac. And what is the amp of 7.2V dc? I want run this vacuum cleaner from the adapter with continuously.
Pls give me reply. I need your suggestion. Thanks.
i got one motor from a little hoover vacuum cleaner but i cannot make it work directly with any voltage, it came with a 3.6 battery pack but batteries was almost dead, wanted to make it run corded but didn't work :c
I have had the same problem with some other things; bypassing the battery and connecting directly to wall power would not allow it to work. Sometimes there is a self-protective mechanism that will prevent the appliance from being destroyed if the battery has a major failure. Thanks for watching and posting your comment. Hope all is well your way!
Any recommendations on where to purchase the batteries? I found a website that sells each battery for 5 dollars. So times 12 turns out to be over $70 which is not worth fixing.
Great question, depending upon where you are you might want to check out a specialty battery store. Nothing fancy; where I am there is a store called Batteries Plus that seems to always have an equivalent pack for things. The other option might be a source like eBay. In a previous comment "Obsession of the Month" mentioned that they found a pack that was not much less than the cost of a new vacuum in which case I would opt for the new vac. I'd love to hear if you found a good alternative... best of luck. Thanks for watching and for the comment.
I have one of these but no charging deck and the battery is completely dead. What projects could I use these parts for? Any cool suggestions? I like rc airplanes and rc cars etc.
There is some great power / RPM with the motor so I am assuming there are some fun options for RC application if you can get the needed volts. I guess the challenge comes in the form of weight. I chose to experiment with attaching to a wall wort to run as a fan/blower but thought I could also convert into a handy little hardwired bench vac that I could mount under a workbench. In general the switches are good for other projects too.
What was this project you used this motor on?
I actually kept the motor with the fan and made a different vacuum. Forced the air through smaller intake to create a more powerful cleaner. I've been using that to experiment with some other ideas I've been working on. Thanks for watching and posting your question!
Do you know what kind of motor it is? I’m wondering if I can use it on an electric skateboard build
that is a great question... sorry, I am not sure the exact specs on the motor. That is also a great idea but I would doubt that this motor has enough torque to move a person on a skateboard... it'd be great if it did though. Thanks for watching and posting your question!
No way .... this is a high speed motor without much torque. You need a motor with gear reduction. Check out eBay or look for a You Tube video on building an electric skate board. The parts will cost you more than a complete unit.
Is it dangerous to touch the wires that are connected to the battery??
Assuming the battery pack is not plugged into an outlet (by way of the vac), then not too bad. It is 14.4v so it isn't holding allot of power when it works. It is less than 2X 9v batteries at once but I still don't recommend testing voltage on purpose.
I have this model and it stopped charging, I removed the Six screws not 7 gently pried the side off and with a bit of fiddling I re-soldered the charging port back onto the circuit board. The charge port has two lugs on the bottom, one lug has a long thin metal tongue which allows for flex and the other is a short one which Is a poor design and looks like it will fail in all of these after the charge cable is inserted and removed a few dozen times... I also considered simply binning the charge port and just soldering a pair of wires to dangle out of the unit and have a connector plug on the wire. If it gives trouble again I'll do that.
All in All, Poor design ...
Overall I do think you are right about the design. I've noticed allot of these in this price range don't last as long as they should and the cost of parts to fix is often not worth it. Love the idea to hack your own charge access... I've done similar on some other devices and it has worked well. Thanks for taking the time to watch and post a comment!
You're way to nice to your vacuum.
Lol... guessing you mean I should have smashed it(?) If it were not for my extreme curiosity to figure out how things work I'd probably be smashing allot of stuff.
