The Kärcher WV 4-4 Plus is a practical battery-powered window cleaner that allows for quick and efficient cleaning without streaks, drips or stains. The electric suction function ensures that water is immediately removed from the surface, so windows and other smooth surfaces are perfectly clean and dry.

The device uses a replaceable battery from the Kärcher Battery Power 4 V platform, which allows flexible use with other devices from the same battery platform. The innovative suction strip made of liquid silicone allows cleaning even right up to the edges, and an LED indicator shows the battery status. The combination of a spray bottle and a microfibre cloth allows for thorough pre-cleaning of the surface, and the vacuum cleaner then effectively removes the dirty water.

Same summary

The Kärcher WV 4-4 Plus window cleaner is a battery-powered model that allows flexible cleaning of various glass and smooth surfaces in the home or at the weekend. The medium working width of 28 cm and up to 59 minutes of operation are suitable for households with larger windows or balcony areas, but also for quick cleaning of shower cabins and mirrors. The device is not best suited for very narrow or divided windows, where manual or narrow-ended models are more practical. It is characterized by ease of use and mobility, but for very large areas, the limited battery operating time must be taken into account.
