hello, I'm really happy with this purchase because when you have large windows it is very useful before the product flowing glass all over the floor and squeegee that leaves trace, the rag and elbow grease it all it's over, with the karcher cleaner I did my 6 windows in 20 minutes not to mention other small windows, but happiness to the windows .I highly recommend it to everyone who no longer want the windows like a chore. by against the glass cleaner that I had a gift I can not find at the top .so for those interested I put in the little half bottle water, white vinegar and two drops of liquid dishwashing result is more than perfect.
