Kärcher WV 2 Premium: what works, what doesn't?
What works well
- Wide AND narrow nozzle in the set: glazing-bar windows and tight areas too, with nothing extra to buy
- Streak-free without wiping: sucks the water up, so no smears and no drops on the sill
- Light & handy (0.6 kg): does not tire you out even with many windows
- Versatile: also works on mirrors, tiles and in the shower
Points of criticism
- Battery permanently installed: cannot be swapped by yourself, send it in if faulty
- Small 100 ml tank: needs emptying more often with many windows
- Drops with a too-full tank: empty it in time, otherwise occasional edge smears

Build quality & everyday use
What carries the Kärcher WV 2 Premium in everyday use: Wide AND narrow nozzle in the set (glazing-bar windows and tight areas too, with nothing extra to buy) and Streak-free without wiping (sucks the water up, so no smears and no drops on the sill). We have to be honest about the weaknesses: battery permanently installed, so it cannot be swapped by yourself and has to be sent in if faulty.
If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.
