Only our most innovative, powerful products bear the signature of technology pioneer and company founder Alfred Kärcher. The WV 8 Signature Line Window Vac is suitable for a wide range of applications. Whether windows, mirrors, tiles or condensation, the WV 8 Signature Line ensures a sparkling result – even at an angle, horizontally or overhead thanks to 360° Comfort!Clean. Cleaning right up to edges and floors is also no problem with the flexible Xtra!Flex® silicone blade, while the narrow suction nozzle is used for narrow surfaces such as lattice windows. In combination with the spray bottle with microfibre wiping cloth, the suction function of the WV 8 Signature Line enables up to three times faster cleaning. The result is streak-free surfaces without annoying drips. The dirty water tank can be emptied easily and hygienically. With a long battery run time of up to 55 minutes, the Window Vac enables long-lasting use on areas of up to 165 square metres, and the 3-LED display provides information on the current charging state. Thanks to USB-C charging, the device is quickly ready for use again.
