Perfect if the space to be cleaned is almost empty. Otherwise the room must be cleared up. Virtual walls and doors are essential. The door sills are passed without difficulty. Not everything is always aspired. If you are not too fussed about the details and if one is occupied otherwise, this machine is convenient. The instructions did not seem obvious. I still have to learn to use it best not to take a nervous breakdown face the nonsense of "Cafardo" cockroach that big is not always where I wish it did not always reaching out to perilous situations and do not obey me the finger and the eye. I do not dare leave him alone to work. In short, a fun gadget that can serve well when one has assimilated the user manual, and a clear conscience when you do not want to spend the true vacuum.
