This device was purchased by me after the disposal of the "Siami know what" super-popular Chinese robot vacuum cleaner. I took the device in the hope that the characteristics declared by the manufacturer would somehow be friends with reality, in contrast to the past negative experience. After 4 months of use, I can say the following: 1. If you are not a complete layman in technology, you will definitely teach Rumba to know and love your apartment. I gave her the starting race as many as 4 times. This allowed the robot to compile and then refine the map. Only after that I gave him a full test drive with cleaning. 2. My 87 squares of harsh stalin with parquet and carpets were completely completed by the robot in 40 minutes. I scrupulously checked everything behind him and came to the conclusion that this is definitely win. Compared to the previous electronic blockhead, the robot cleaned up much better. Despite his round nature, in the corners he walked one and a half times deeper than the Chinese before this case. 3. Before cleaning, I told him where he should not go on pain of death. He understood and honestly did not climb into dangerous areas even for moving, which the same Chinese frankly did not understand. 4. It turned out that Rumba copes with pet hair much better. If the previous vacuum cleaner was already driving by the middle of cleaning, as they say with a full mouth and simply rearranging the dust with its brush, this one securely packs cat lint in its container. Nothing sticks in the dust of the receiver, nothing prevents the garbage from being drawn in. 5. During the operation, I only changed consumables once. On the Chinese for the same time, I changed them three times. 6. The fact that the vacuum cleaner independently empties its garbage container into a container puts it higher in the evolutionary chain of vacuum cleaners by a whole step. Now my task is not to clean it after each cleaning, but only once a week to pull the bag out of the container. This is definitely a big step for all robots. Overall: The purchase met all my expectations. The vacuum cleaner is really worth the money.
