Kärcher WV 6 Plus: what works, what doesn't?
What works well
- 100 min battery life: longest in the comparison, a whole house in one go
- Large 150 ml tank: needs emptying less often than the 100 ml devices
- Precise LED charge indicator: multi-stage, so you always know how much battery is left
- Streak-free & versatile: windows, mirrors, tiles, shower
- Kärcher quality: Established manufacturer with good spare-parts supply
Points of criticism
- Only a wide nozzle in the set: the narrow glazing-bar nozzle has to be bought separately
- Long charging time (170 min): in proportion to the runtime; it takes a while from empty
- Battery permanently installed: cannot be swapped by yourself

Build quality & everyday use
What carries the Kärcher WV 6 Plus in everyday use: 100 min battery life (longest in the comparison, a whole house in one go) and Large 150 ml tank (needs emptying less often than the 100 ml devices). We have to be honest about the weaknesses: only a wide nozzle in the set, so the narrow glazing-bar nozzle has to be bought separately.
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.
