For a long time we doubted the need for this device at our place, but we decided to take it and never regretted it. Firstly, there is no need to vacuum every day - the robot copes with its duties by 90% (of course, there are some places where it cannot reach, for example, a baseboard). Secondly, it collects all the garbage that stuck to the legs and annoyed. Third - wet cleaning daily. The list can be continued indefinitely))) After evaluating the purchase, we gave our parents and sister the same assistant - everyone is happy! We recommend to buy.
