I received a vacuum cleaner as a gift from my mother-in-law. She has the same vacuum cleaner, proved to be worthy in operation. I set a work schedule through the application, while I'm walking with my daughter in the apartment is being cleaned. The rollers are in good contact with the floor and therefore removes even small debris. There is also no hair after cleaning. The robot is easy to control with a smartphone, and it also self-cleans itself. I really like the vacuum cleaner both externally and functionally.
