Eventually passes away in the most unexpected location. It looks like a Christmas tree and has lights that flash in a variety of colors, but it does not clean anything typically. The only time I was successful in cleaning the apartment was when I followed him around with the cleaning application active. Follows the timetable for departure and makes stops in unpredictable locations. Does not make its way back to base. Perhaps he considers an area of 100 m2 to be rather a huge one. Ideal for a studio or one-room apartment that is at least 30 square meters. Extremely unfinished software; it does not actually perform any functions. The earlier rumbas are still operational, however these are over 100 sputs that have been thrown away. Cannot be returned, and there is no guarantee offered. Addition. I installed amplifiers all over the flat on the advise of the provider in order to improve the power of the wifi connection. Sense - zero!
