In the beginning, I bought this sweep robot with suspicion. And I told its customer service staff that if the trial of Deebot is not satisfied, I will apply for a refund. I used the Deebot at once after I received it. For several days' trial, it turned out to be a good product. For the hair and dust on the floor, my Deebot can cleaned up clearly. However, the effect of its mopping function is not as good as that of its sweeping function. What’s more, by connecting to ECOVACSHOME in my phone, I can set up cleaning routes of Deebot and create virtual boundary and house maps. In this way, I can let it to clean any specific area as I like. However, sometimes Deebot will be offline, which needs ECOVACSHOME ’s developer to improve. When the Deebot is working, it can automatically recognize curtains, fan seats, etc. In most cases, Deebot can get out of trouble itself. After running for a round, I emptied all things in the bottoms of the three bedrooms, and adjusted the position of the furniture that hindered the Deebot forward, and began to use it daily. After nearly two weeks, the cleaning work of the floor was basically given to the Deebot, and this make me feel much relax.
