In general - ok. At first, you have to dance with a tambourine when connecting to the network and to the application, but over time, the negative impressions of this are forgotten. With its pros. Experience of use - just over a year. Mode of use - 2-3 times a week up to 30 -20 percent discharge. The battery is still holding a charge well. There were no problems with the technical device, the service life of the brushes came to an end, which the vacuum cleaner reminded of, but their condition is still a solid four. During this time, I replaced a thin filter with a spare tire, but rather for aesthetic reasons. Then I came up with a life hack for a thin filter. From a medical mask, you cut out a piece of fabric and insert it into the dust collector in front of the filter housing. The fabric will separate the filter from debris. This makes it easier to clean the vacuum cleaner and the filter does not clog with large debris, it lasts longer. You can select the performance mode and, therefore, the noise level of the vacuum cleaner, which is convenient for cleaning the room before going to bed. Smart enough and persistent in cleaning. Even the grandmother, critical of all gadgets, praised him for not allowing dirt to pass through and blocking a significant part of the first one with the second pass: "your puck sweeps cleanly." In general, I am satisfied with the vacuum cleaner. Got cons: Loses a card. If you created a map of the apartment (and for this you need to prepare all the rooms so that the robot goes around them around the perimeter), then after a while it turns out that the created map is not available and everything has to be repeated again. This takes time and effort, so after a couple of card losses, I refused the opportunity to set the cleaning zone. Because without a map of the apartment I can’t send him to clean in such and such a room, I have to carry him there on the handles. It's inconvenient, the function is there, but it's impossible to use it.
