What Experts Agree On
What Experts Love
- ✓ Dual ultrasonic spray nozzles nebulize water into 15-micron mist and keep the microfiber pads evenly damp the whole cycle, which is what suppresses the streaks and swirl marks cheaper bots leave.
- ✓ Its 4.5m safety rope is rated to a 200kg breaking strength the strongest tether in this guide so you can run it on high-rise exterior glass with confidence.

Common Criticisms
- ✗ It is corded and uses only one cleaning pad, so heavily soiled glass often needs a second pass or a manual touch-up at the very corners.
- ✗ At roughly 64 to 68dB it is as loud as a vacuum, noticeable if you run it in an occupied room.
