"Bought this on a recommendation from a friend. Why did I not buy this earlier! You have to wash your windows as normal but then you use the Karcher to suck the water up and dry your windows. You will need a cloth to wipe the edges but it takes seconds. It is a bit awkward when getting to the bottom of the window where there is a large ledge as the karcher will knock into it, so you have to turn it on its side to use. However, it is a godsend and knocks so much time off cleaning as well as being effortless. I cant do upper floor outside windows with this but that is probably because my windows are not accessible. so far I have used it on my windows, mirrors, bathroom tiles & shower unit. It is good for spillages on hard floors too. Mine came with a cleaning kit (little plastic bottle) but really you do not need it - a cloth and soapy water is just as good. Save money, buy one of these and sack the window cleaner!"
"Having recently bought a Karcher window vac and being very pleased with it I spotted this extension at Screwfix and promptly bought it. I can now clean windows quickly that would have required steps or ladders to clean previously, also meaning they may get cleaned more often :)"
