Has pros: container that cleans itself using a bag-based system Creating maps of the interior, as well as limiting access to certain regions via the application It is capable of overcoming low sills; in fact, I had to attach a bumper to the Ikeev chair so that it would not climb along the rear lower crossbar and crush the wheels throughout the entire apartment if I did not do so. Got cons: He will occasionally leave the base and then quickly drive back (this typically takes place after turning off and then back on the electricity, although this is not always the case), and it is especially exciting when this takes place at night. Poor obstacle recognition sensors; continually colliding with the legs of chairs and other furniture; nonetheless, this does not always happen; chances are 50/50. You still need to clean it since dust gets stuck to the front bumper, hair gets wrapped around the wheel and side brush, and so on. The charging error 3 will appear in the program at random intervals, but the robot will continue to function normally. There is no way to check online to see where he is driving at the moment or what he has cleaned; this information is only available after the cleaning is finished.
