It's good to watch how he departs line by line in the room and not capitulated even before more difficult to reach places. Under our detached bed, for example to get only from the front, and after several unsuccessful attempts by the closed side he finally drive around yet and made to work.
Unfortunately, I can not confirm the various statements about the good cleaning performance. It is not about any corners that the unit by design can not clean, but to free surfaces me.
Living room: wooden floor with joints. Sure, the Navibot not suck, but returns only. In this case, in the joints. No ideal substrate, so will not further notice. Dirt from the rabbit hutch, a little straw and the occasional droppings, he liked to push them with his front, rotating brushes aside instead incorporate itself.
From the bedroom, Flat, even laminate flooring. The same image, dust bunnies under the bed are not equal to one, but often "first" swept aside.
In addition to the rather parlous state of the sweeping performance Navibot is here his "intelligence" undoing. He pushes the dirt into a stored as cleaned area, he never goes there again on a second attempt over and goes sometime complacent in hibernation.
The hope, in future only have to clean the nasty corners with the hand vacuum cleaner, has not fulfilled. Even flat surfaces are cleaned at best superficial and are satisfactory even after a second passage clean.
A nice toy, but ultimately not really useful and it too expensive. The Navibot goes back again, too bad.
