I had no experience using a robotic vacuum cleaner before. I considered a vacuum cleaner with a self-cleaning base, but refused it because you need to come up and put a tank of water and a clean rag before each cleaning if wet cleaning is done. I opted for this vacuum cleaner and were very pleased with the purchase. Got pros: At the standard suction power, the noise is much less than from my usual vacuum cleaner. Spends about 40 percent of the charge on 70 squares. Goes around all obstacles without even touching them. A lot of components on Ali. Cons: With the obstacle avoidance system enabled, a high pile carpet is seen as an obstacle and does not always run over it on the first try. I have almost no carpets and therefore it is not critical for me.
