The new generation of battery-powered window vacs and their advantages

More compact, handier and lighter.

The new WV is 10% smaller than its predecessor, ensuring that lower window edges are more easily reached. You can therefore clean down to the lower edge of the window without changing the handle you are using.

Ergonomic and compact construction style allows you to attain an optimal cleaning result even more easily than before.

Cleaning is noticeably easier and 3 times quicker compared with conventional cleaning methods. What's more, the high-grade lips and the suction function are guaranteed to leave your windows sparkling. The convenient battery operation and more compact design of the new generation guarantees maximum flexibility when cleaning all smooth household surfaces. Try it out and see for yourself!

Längere Akkulaufzeit und größere Flächen reinigen

25% longer battery run time

In terms of area, the WV 2 is capable of cleaning around 15 m2 more than its predecessor on one battery charge.
