I bought it as an assistant to a robot vacuum cleaner (sweep the little things, vacuum the sofas, under them, the PC case, etc. places where the robot cannot reach). Wireless convenience is incredible! Gave relatives the same for cleaning a small apartment and a car. Great! Its pros: Powerful when used at maximum power. Lots of baits. Nozzles with brushes have a drive to the brush itself - it turns out a vacuum cleaner + electric broom, due to this, the efficiency is really at the level of a decent corded vacuum cleaner! Got cons: It is rather weak at medium and automatic power (an electric broom, in fact). The battery at maximum power lasts a maximum of 15 minutes. This is right next to the floor in an apartment of ~ 80 meters, where you don’t need to clean anything special.
