If you change consumables according to the instructions, then the operation is a little expensive (but probably consumables are a common theme for all robots) Different pros: The brushes are made in the form of silicone rollers, which is extremely convenient in the presence of pets. I have 2 cats and this question is very relevant. Very easy to maintain and manage. Cats are not afraid of him. Cleans cleanly - if every day or every other day - you can say perfectly. Has cons: Once he cleaned one room and did not go further, he returned home, wrote that he had cleaned everything))) it’s not clear why, but he usually cleans the whole apartment.
