A fantastic heist for 20,000. It does a good job of building a map, there is the ability to construct walls, and you can select which regions need cleaning. The fee is sufficient to clean an area without carpets measuring 120 squares. It doesn't get lost, it always promptly finds a charging station, and as a result, it goes to the cleaning for 10% of the charge, which is a significant improvement over the previous model, which did not have lidar. It doesn't poke into objects like a blind kitten. It doesn't get lost. Wet cleaning isn't very effective because the water container isn't very big, the strip doesn't extend over the entire width of the robot, and there are still dry spots on the sides and in the centre.
