Battery backpack vacs compared

In this feature, we compare four of the industry's best battery backpack vacuum cleaners.
We aren't stating any of them as better than the others, more to highlight certain features and benefits of each one to give an idea of which machine will suit which application...
The findings are interesting - these are the machines:
Makita DVC261
Karcher BVL 3/1 Bp
PacVac Velo
Numatic RSB150NX

I have the numatic rsb150nx and am absolutely delighted with it, takes 1 battery and it lasts very well after a 2 hour charge kind regards to you and everyone out there Mark from Billericay 😃👍

I came here to see the Kärcher and specifically the profile, how far it extends from your back. You never moved sideways to the camera!
This profile issue is very important if using backpack style vacs for residential cleaning service. The large, barrel style are too difficult to maneuver through a resident confidently (and avoid knocking into doorways and worse, lamps, etc)
Sadly, this video is of little use for my purposes

[@reviewassistant6891]

if a basic 200£ plug in is 100% goodness, how much suction does the bestbatery get?

Do any of the Cordless backback vacuums have the blowing option???

Hi there. Do you have any information on the SureVac Stormpac battery backpack vacuum. It's hard to find info out there. I work at a school in Qld and am limited to which types I can buy. Pacvac is in the preferred list however it's nearly $1K and don't think they want to spend that much.
