After long hesitation, I bought this robot aspi, and here I must say that I am made all satisfied. Very little noisy. Effective. I have a very big house, and I do work piece by piece. And the result is impeccable, especially in cat hair, whose long hair tend to swarm around the Maisonet on tapis.Bien on, you better be a small son or the cables running on the soil and the chairs. On the floor, the brush effect brings more of polish. Very effective also on carpets, rugs. I do not regret my purchase.
