Review on TECBOT S2 Robot Vacuum Cleaner: Advanced Visual Mapping, 2000Pa WiFi/App/Alexa, Self-Charging & Pet-Friendly - Ideal for Carpets & Hard Floors (150 Mins Run Time) by Christine Bryant

I really liked the robot. The only annoying thing was that the side brushes pressed down so hard on the floor that they could get under my carpet and snag on it. It also said something like "Ready to clear the master" which was a bit odd. I sent it back as the brushes got stuck under my carpets.
