11 Window cleaning devices 04/2019

While the dirty water runs down the glass with a conventional squeegee, electric window cleaners simply suck it up - practical not only for windows, but also for mirrors or tiled walls. In the Stiftung Warentest window cleaner test, eleven devices had to prove themselves, including models from Kärcher, Leifheit, Vileda and Vorwerk (prices: around 30 to 250 euros). Conclusion: Many window vacuums have a hard time on tiles, but eight devices did well.
