OverviewUBOT EXVAC660 Robot Vacuum Cleaner with Mapping System: Sweeping and Mopping 2in1 UBOT EXVAC660 PLATINUM is obviously brand new generation hybrid robot cleaner with superb performance and more reliable cleaning efficiency than any other models of the past. It is not Vslam navigation robot though, it has really outstanding navigation system algorithmically. Powered by more precise sensors and elements including gyroscopes, infrared sensors, brushless motors, etc, UBOT EXVAC660 PLATINUM can perform as well as its counterpart models who claim to have Vslam or Laser Slam navigation. Since the infrared signal of the machine's anti-drop sensor will be absorbed by dark substances, the machine is not suitable for black or other dark carpets. Under strong light conditions, the anti-drop sensor will fail, which will cause the machine to fall. In addition, if the ground is uneven or the glass surface is easy to slip, it is not suitable for glass terraces.
