The suction power of the robot is excellent, it cleans very well and does not scatter dirt. It also automatically increases suction power to high as soon as it detects a carpet and cleans until the battery is low, then returns to the dock and charges to pick up cleaning where it left off. Its accuracy is really good as long as it hasn't been manually interrupted or moved to another location. The robot tries its best not to get tangled in the cables and succeeds in most cases. unpredictable, but eventually he will clean the whole apartment and write down everything that has been done. I think if it is placed at one end of the apartment the path is more predictable.
