I love this robot so much. Firstly, it cleans the surrounding very tidy and smooth. Secondly, it doesn't make much noise so I don't have to worry about how it will disturb my child. Thirdly, this robot is very good at sensing. It can sense the wire and avoid the item. So surprised because other brand, most of the time it will get stuck and the robot can't be use anymore. However, this robot is so good definitely can last a long time. Moreover, it have brush which can brush off the long hair without getting stuck on the wheel so I don't have to worry about it anymore. Lastly, it have large compartment so I don't really have to empty the bin daily because it will automatically emptied the bin to dirt compartment. So once the compartment full, then only we clean the bag. So convenient ! Really a good vacuum, just control using my handphone and I can relax and enjoy my day.
