The robot vacuum cleaner connects with the application on the cleanliness of 2.4 GHz! We suffered for half a day and tried to connect it to the purity of 5GHz. Keep this in mind. Vacuuming under the bed has always been difficult, but now it's always clean. Collects dust, hair, feathers (we have parrots) - excellent. Driving on the carpet - turns on the turbo mode. Wet cleaning is good. A full tray of water, at the maximum water flow rate (out of only two), is enough for an area of 50 m2. No problem getting back to the station.
