For a clear view: 6 electric window vacs

Cleaning windows is tedious and time-consuming – work is easier with electric window vacuums. The devices complete several steps in one wash, and no dirty water runs down the sides. We present six window cleaners, four cordless window vacuums and two wired window cleaning robots. We have arranged the products in price – starting with the cheapest.

Window vacuum cleaners are a combination of window pullers and hand-held vacuum cleaners; they are also suitable for cleaning mirrors and tiles. The gadgets cost between 30 and 250 euros and are usually sold as a set, consisting of a spray bottle with a wiper attachment for washing in the window and the battery puller. The vacuum cleaner draws the dirty water from the rubber lip inwards into the collecting container. If you want to clean many windows in succession, you should pay attention to the size of the tank. One battery charge is sufficient for at least 100 square meters.

Window cleaning robots go one step further: they suck themselves in and clean the window independently in the automatic program. It has a price. In tests, however, the robots usually only perform mediocre, and conventional handheld devices are often unable to hold their own. When cleaning large window areas, however, the wired devices show their strength.
