whats the maximum distance that you can clean windows without moving the trolley with you?
Also the white/clear hose which comes with the machine where can I get some?
I have a 7 metre extension hose to use with the trolley I built. I leave it on the drive and it reaches everywhere usually.
White/clear hose - hmm not sure. I use 5mm clear polytubing, which you can but per metre from B&Q (75p per metre) you can also buy all of the little fittings there too. It is the same type that goes inside most fibreglass wfp's
