I am very happy with the transaction, the seller got in touch with me right away, everything was done in a nice, quick, and correct manner, and the shipping was done quickly and with beautiful wrapping. Excellent comments and criticisms. Both the product and the merchant come highly recommended from me. Below are some advantages: Since this is the first robot vacuum cleaner, there is nothing else that it can be compared to. I had lower expectations for him, therefore I was pleasantly delighted when he delivered a useful application (Roborock) that, while the connection to WI-fi was a touch clumsy, the application itself was straightforward. It is simple to modify the type of cleaning and the amount of suction force because he rapidly constructed a map of the room and divided it into zones himself. It has a powerful suction, is very quiet, can clean an entire apartment (100 m2) on a single charge, and it does not discharge all the way. During the initial cleaning, I was able to collect enough trash to fill four buckets. Excellent results with pet dog hair. We have not yet experimented with wet cleaning. Con: There is not enough of a signal regarding how full the container is, so you have to focus on using your eye to judge how full it is.
