I bought a roomba s9 + instead (the reason for refusing the rumba is a stupid vacuum cleaner, possibly a marriage). It rides great on carpets, unfortunately I had to unscrew the silicone side brush (it clings to the pile and a knot is formed, after which the robot gets stuck). Roomba s9 has a side brush made of pile (I could be wrong), it just flattened out and did not catch the pile. In general, I recommend the product, I will definitely buy the base if there is support or a new model of the robot. I'll wait for a new firmware or ate the router. Cannot find the base when returning from the next room, or just finishes work. ate September 26, 2022: The robot started to get dumb, can't find the base, gets stuck, constantly asking to fix the bumper. You buy a device to make life easier due to lack of time and high employment, but in the end you have to run around service centers. In general, the technology is crude, problems with finding a base are just a fail. Previously, he could start the robot from work and very rarely he did not find the base. Now with every cleaning. P. S. The robot and bases are periodically wiped. I can't recommend yet.
