We bought it based on reviews. Before that, there was a robot from another company. It flew in 2 months, fought like a blind kitten around the house, no cleaning, garbage poured out of the container during cleaning . There is something to compare so to speak! I always liked Redmond, almost all the equipment of this firms. The robot did not lag behind, the cleaning is quiet, I calmly put the baby to sleep without stopping the cleaning. The control in the application is convenient. The card does not lose. when you wash the floor with handles, parquet, for example, pour a bucket of water on it?! I am satisfied, with three children the assistant is indispensable. I hope it will last a long time.
