As the first robot vacuum cleaner in my life, I like it - not complicated controls, concise design, does cleaning by 5. A more complex model will require more knowledge and attention, but here everything is clear and simple. By the time he starts to work, and if there is no one at home, I advise you to clear the field of activity for him in advance. There is a risk for the robot to catch on a small obstacle or get tangled in the wires. It moves well in open space, gently cleans corners and skirting boards. Cleaning only dry, once a week I do wet and the house is clean.
