In general, the vacuum cleaner is very smart, there is the possibility of wet cleaning, charging is enough for 35 squares of one, cleaning time is about 20 minutes. You don’t really need to look after him, he is able to travel out of tricky areas himself. With its pros. Nimble, builds a map of space, the ability to connect through Alice and the application. Oriented in space well, quickly reaches the docking station. Good at overcoming obstacles. Quiet, the cat is not afraid, but watches the talking device with apprehension. Wool cleans well, sand too. Has cons: It was very difficult to connect to the application, there was a router error, it helped to select the region (UK). Suddenly, someone will come in handy, if there is the same error, you need to select the region whose language the vacuum cleaner speaks. BUT I haven't been able to connect to Alice yet :( Half a star for that, and half for the lack of thorough cleaning. One brush does not always pick up all the debris.
