(checked 2026-10-10)Very small sample (63 ratings).
GadgetGuy rated it 9/10 for streak-free cleaning right to the edges, with a safety rope and backup battery. But that review is from 2021, and the small Amazon US sample shows a high share of 1-2 star ratings, with owners reporting it gets stuck and misses parts of the glass.
Top complaints
- Gets stuck; misses parts of the glass
Amazon's review summary says stability is a concern because it gets stuck while cleaning, and some owners note it doesn't clean 100% of the surface.
- Mixed streak results
Amazon's summary says streak-free results are mixed. GadgetGuy readers also reported streaking, mist missing the glass in a slight breeze, and marks left on windows.
- Slow and needs an outlet
GadgetGuy says it takes longer than cleaning by hand, needs a nearby power point, shouldn't be used in wind, and isn't for rough or pitted glass; its finish tone is easy to miss. It measured 60 dB at 1 m.
