Independent Evidence & Red Flags

- Battery Decay: Independent users have noted that while the battery lasts 90 minutes when new, that capacity can drop significantly after six months of frequent charging.
- Bristle Durability: Some users report that the stiff bristles on the corner brushes can splay or flatten after only a few uses on rougher surfaces like outdoor stone or heavy-duty grout.
- Lack of Certification: Beyond standard electronic safety ratings (like CE or FCC), there are no official “cleaning certifications” for these devices; their effectiveness is largely subjective.
