Fantastic ally. Service Wait 5 minutes while I clean and mop the floors. Further cleaning is not required for routine maintenance. Even before making my final decision, I had been keeping tabs on a popular Chinese brand but was unimpressed by its prices. I bought a camera instead of Lidar for the same price. Light is required by the camera. Without a camera, his sense of direction is off. The conclusion was reached since the apartment is dark in the winter. This: + cost $18,000 + Lidar + Creates maps + Follows a plan + Precisely delineates Virtual Walls + Includes a sweep and mop of the floor + Conquers the in-room washer and dryer Listening to the banging of a drum while on the clock. less noisy as the iRobot. Me and my better half are ecstatic.
