I would put 3+, as it performs its function and the house has become much cleaner. For my money, it’s quite normal. Has some pros It collects dust with a bang, it is easy to clean the container, you can control it from your phone. I liked the ability to overcome obstacles, tupit only in the most difficult places. With its cons. The function of wet cleaning for three, if less than 20% of the charge - immediately completes the cleaning, which is not very clear. I can't change the language of sound notifications from English to 2022. It does not remember where the charge is, so until it finds it, it will take about 5 minutes, and in the return mode it moves a little faster than a snail. All setting functions (language change, ate, mode switching) are available at least after 30% charge and at the charging station, extremely inconvenient
