Cleaner windows without the usual drips and smears, that is the promise of Kärcher’s WV range, and the WV 5 Plus sits towards the more premium end. It goes up against other cordless window vacs from Vileda and Bosch, aiming to speed up the final stage after you have sprayed and wiped, by vacuuming away dirty water instead of chasing it with cloths.

Who will get the most out of a window vac?

If you have large panes, shower screens, mirrors or glossy tiles, a window vac can save time and cut down on streaks, because you are removing moisture rather than redistributing it. The WV 5 Plus adds an edge guidance system to help you run closer to frames and seals, where water tends to collect.

  • Three stage battery indicator, clearer sense of remaining runtime mid clean
  • Cordless vacuuming, less dripping onto sills and floors as you work
