I need an update on best cordless vacuum cleaners.

Do any of these devices work with commonly available power tool battery systems?

I think De Walt make a cleaner, you'd have to check, but I'm a detractor from Dyson, we've bought a V6 never worked properly, they changed out some parts, but we've still never been impressed with it.

A new battery for a Dyson V11 is £85 and out of stock. It looks like a highly bespoke design.

You can only use a new battery for a V11 if you have the click-in model though. Otherwise, like the V10, it's not supposed to be user servicable.

Incidentally the weight of a V11 is 3kg. It's only slightly heavier than the V10 which I have. If you are using the normal floor attachment, some of the weight is carried on that.
