Product details

Only our most innovative, high-performance products bear the signature of technology pioneer and company founder Alfred Kärcher. The WV 8 Signature Line cordless window vacuum is suitable for a variety of applications. Whether it's windows, mirrors, tiles, or condensation, the WV 8 Signature Line delivers a brilliant result – thanks to 360° Comfort! Clean even at an angle, horizontally, or overhead. Edge and floor cleaning are also no problem with the flexible Xtra!Flex® silicone lip. For narrow areas, such as sash windows, the narrow suction nozzle is used. In combination with the spray bottle and microfiber wiping cloth, the suction function of the WV 8 Signature Line allows for up to 3 times faster cleaning. The result is streak-free surfaces without annoying drips. The dirty water tank is easy and hygienic to empty. With a long battery life of up to 55 minutes, the cordless window vacuum enables extended use on areas up to 165 square meters, and the 3-LED display shows the current charge status. Thanks to USB-C charging, the device is quickly ready for use again.
