I have to say that the cordless vacuum cleaner has a low power problem, I fully charged the autobot and used it continuously for about eight minutes, then it automatically stopped running. Fortunately, the battery indicator has a low charge reminder, so that I can charge it in time. This is the \"unexpected\" loot I sucked from the surface of the sofa in eight minutes, the dust is mostly blocked in the insulation net, and the water washed clean.
