Leifheit Fenstersauger

From the jury's assessment

If you are still cleaning your windows the traditional way, you should quickly change your view, because the new window vacuum cleaner from Leifheit makes this work much faster and more comfortable. Dirty glass areas can be cleaned for up to 35 minutes; this does not only count for windows, but also for shower enclosures or cooking hobs. Thanks to the optional handle, you don’t need the stairs any more while cleaning. If the runtime is not enough, the additional battery can help you to clean for how long you need to in order to create undisturbed views.
