This Robot Vacuum worked very good in my living room and kitchen, the floor was cleared very nice, all the corners was cleared very well, it returned to charge station with accuracy, especially I really like its dumping all the dusts into the station automatically when it returned to its station which is very convenient, also I found it avoided to bump into obstacles with its sensor, it cleared under my dining-table with a lot of chairs, great to find it could get into it and get out with no issue, definitely it's a very great Robot Vacuum which is deserving recommendation!
