Only our most innovative, high-quality products bear the signature of technology pioneer and company founder Alfred Kärcher. The new WV 7 Signature Line: recognisable at a glance as the best device in its Kärcher product category and our new benchmark in Window Vacs. The new longer suction lip removes excess moisture from large areas after just one battery charge. The extra-long battery operating time of 100 minutes means you can keep going for longer. Thanks to the display showing the remaining time, you can plan your cleaning better. As usual, the intelligent combination of spray bottle and microfibre cloth, together with the Window Vac's suction function, guarantees highly effective cleaning and sparkling clean windows, without streaks or drips. The ergonomic WV 7 Signature Line has also undergone a facelift, giving it a modern look.
