As a result, he does not see the recessed base of the cabinet below the radar and does not call in to clean it, he thinks that the front of the cabinet is the edge of the floor, although the base is recessed another 8 cm deep into the cabinet. You could just take his cheaper model "dreame d9". Moreover, there is an excess of power here for laminate (we don’t have carpets), a third of the power is used. But in general, the mental abilities of the vacuum cleaner have no complaints, smart. Life with him became better and cleaner.
