The battery-powered window cleaner WV5 Premium ensures streak-free clean windows in record time. This model of this version combines the usual features of the WV 5 Premium - a replaceable battery system, an additional rubber strip on the holding handle, and long battery life - and another advantage. The new model comes with two additional microfiber cloths, one for internal surfaces and the other for external surfaces. This ensures that windows, both internal and external, will be cleaned quickly and without streaks. Thanks to the ultra-narrow nozzle, even smaller windows will be perfectly clean.
