I definitely recommend buying, I didn't notice any disadvantages.
Smartphone control. Choice on the map in any sequence in any combination. There were no communication breaks. I recommend.
Pros
Named Valera, checked in all modes. Smart. Shustro built a map of all the rooms in the apartment. Doesn't make mistakes. The cat followed him around. I climbed under the sofa and vacuumed and washed the floor there. You can't get a mop there. The cleaning quality is good. If the floor needs to be washed, and not wiped, it is better to select the "V" mode, while it tries to wipe one place two or three times. Unusually returns to the base for recharging - at a good speed, clearly bypassing all obstacles. The base parks very carefully. I am very satisfied with the purchase.
Cons
Glossy black surface - any speck of dust, like a brick. It is impossible to remove and rinse the cloth while at the base. It is necessary to turn off and rotate the case by 180. It does not wash windows (just kidding).
With its pros.
For its price, almost the best option, take it if you don’t have fleecy carpets and children’s toys
With its cons.
Long pile is a problem, curbs over 1 cm in height are a problem, sometimes it gets stuck and swears to be rearranged
