It really annoys me how expensive these are. I have had other makes which have been useless. The karcher window vacs just work.
These aren’t very good, mine lasted about 8 months Kärcher replaced ( good service) this one also broke after 8 -10 months. The squirter bottles are good though:)
Cheaper here even with postage. Also cashback available https://www.kaercher.com/uk/home-garden/window-vac/wv-anniversary-edition-16334760.html
