hi have you any recommendations please, don't want something too heavy for the cleaners

I looked at cordless, silly prices! bought a used nilfisk UZ 964 and it is perfect for the job you mention - long chord - we do a large facility with three stairwells so it will be well used! and no charging palaver. small bags but I know nilfisk and they are one of the best names in serious vacuum cleaning - amazing how much soil you can recover (from what looks like cleanish carpet) and hence less to extract when you have to wet clean or encap

Hi

Just one of many options for you.

http://systemhygiene.co.uk/taski-smart-battery-powered-dry-tub-vacuum-cleaner.html

I have a used one with charger and 4 batteries that don't need anymore.

Batteries don't last but can be regenerated - check here http://www.recellyourbattery.com/taski

I am not going to invest as don't have use for the vac anymore.

It has some wear on it but overall in pretty good condition.

its really well made.

if interested I can email photos. I can let it go for £120.00
