Took my mother and father. Apartment 62kv, two carpeted rooms throughout the apartment. In light of the fact that the robot 1S version has so many flaws, it is not something I would recommend purchasing under these circumstances. 1. The battery is weak, and it is not sufficient for a comprehensive cleaning when set to the standard setting. 2. You're an idiot for taking the same route over and over again, which is a waste of fuel. 3. The amount of time spent cleaning up at the end was excessive. Ps, my first-floor unit is sixty square feet. It cleans in fifty minutes and consumes forty percent of the charge while doing so. After scrubbing and beating the corners for a total of one and a half hours, this light then goes to the charging station without having completed the cleaning cycle. After more than two hours of charging, you will have to select another period of time during which it will not be an issue.
