I don't myself at the moment I just wear it on my back but it is heavy. I have toyed with the idea of a trolley but have yet to look into it. to be honest cleantech fitted the on/off connection to the tubing so I switch it on then use the control to switch it off and on. So I leave it on the floor beside me if I have a big group of windows in a close area like an entrance area then put it on my back whilst doing windows that are on a stretch that is basically continual moving along. Honestly though I can't help but name drop cleantech because I was expecting to have to get the unit then fit things and change things but instead I phoned them ,told them what I needed and they did the lot without even telling my they would. I was expecting a box of bits and got a system ready to go to work with.
