"With 160 panes in a series of cottage style windows this machine has done a superb job. Cleans well, smear free, and sucks up all the condensation drips too. Needed both small and large heads for best productivity. Drawbacks, two. Battery life meant enforced breaks twice in the job while it slowly recharged itself. The one size spray bottle attachment is too wide and too cumbersome. Used my own sponge and dish. Overall, does a great job and leaves sparklingly clean windows."
"Look at this on many websites trying to make up my mind. Ordered from Screwfix and picked up from local depot 30mins later. Cleaned all insides of 3 bed house on less than one charge. Pleased with results. Can streak at first go but mastered eliminating this after 2nd window. Would recommend."
"How did I ever manage window cleaning before now. I had a window cleaner! This equipment does exactly as the advert states. My only complaint is that the battery does not last long enough to clean my windows inside and out. Best to arrange to have lunch in the middle of the job so that it recharges the battery in between. The final result is well worth the money."
"Very good really but not streak free as Karcher claim. hence the 4 stars. I've waited around 3 months while I trial it and me using it and try as I may, and good as windows and mirrors look as soon as you do them, come the sun and there the streaks are. Faint but there. Had words with Karcher and they said make sure the head is clean (I did) and use their cleaning solution (I was). So, I now look for any signs and polish them off with paper towel. Having said all that, it is the best glass cleaner and method I have across yet and I would recommend it."
