Both say right away, this vacuum cleaner is not a dyson or other powerful brand.
The advantage of this robot is the frequency of use, we programmed it aspires home on Monday, Wednesday, Friday
The only thing we have to do is tidy up the house. The first time, he was stuck on a towel in the bathroom ...
He makes 90m² 3 charges (it recharges itself, is happiness).
It is not very predictable in its movements (even if it is methodical), so it is better not to be present while working.
