Kärcher WV 1 Plus: what works, what doesn't?
What works well
- Cheapest Kärcher: brand entry from ~€44, streak-free Kärcher technology at a small price
- Lightest device (0.5 kg): very handy, fatigue-free even overhead
- Streak-free like the big ones: same suction technology, clean panes without smears
- LED charge indicator: shows the battery level
- Ready to go: spray bottle, cover and concentrate in the set
Points of criticism
- Only 20 min runtime: too little for many windows, then WV 2 or WV 6
- No narrow nozzle: glazing-bar windows only with a separate nozzle
- Battery permanently installed: cannot be swapped by yourself
