The very first robot vacuum cleaner could give the impression that it is cleaning well at home, but in reality, it is amassing so much dust that it looks like a cushion made of felt has been placed in front of the filter. The unit can be cleaned in around an hour and fifty-five minutes. When traveling on carpet, the vacuum's suction force is automatically increased, and it easily overcomes thresholds of one centimeter. The cat has a home, the wool is perfectly sucked in, and the air is blasted out correctly; using this stream, it does not blow dirt over the area that has already been vacuumed.
