I just received my Wyze Vacuum and was excited to try it out with the new Lidar mapping system. I am less excited now after trying to map the cleaning area 3 times and having the vacuum lose the map all three times. Who has time to shepherd the vacuum around the house (that takes about 2 hours), moving furniture, keeping it from going under sofas, etc, and getting caught in corners, only to have it lose the map and have to start over?
One of the problems is that the vacuum has a very difficult time trying to dock itself on the charger. First of all, it takes a very round-about route back to the charger, then it maneuvers forward and backward and round and round for about ten minutes or so before it will dock. Typically, it will finally place its contacts onto the charge, announce that it is starting to charge, then immediately move away from the charging unit and maneuver around some more, then repeat the process over and over until it finally stays in contact with the unit.
Unfortunately, after it does this, it also erases its map, especially if you stop it in mid-cleaning-mapping and tell it to return to the charger. After it’s done fussing with the charger and finally connects, it ten erases the partially-constructed map.
On one trial run, it ran out of charge and returned (eventually) to the charger, then after it had received enough charge, it recommenced cleaning/mapping, but midway through this session, the map became so corrupted that it could no longer find its way around and started going diagonally across the room in an unrecognizable floor plan it had imposed onto a previously-perfectly-generated map.
On another run (after I had to reset the map), it completed mapping the entire floor, then returned to the charger and fussed around the charging unit for at least 20 minutes backing into the charger, then moving away again, then backing into the charger, then moving away. I finally grew frustrated with it and physically moved it into contact with the charger–and it erased the map it had just spent two hours creating.
So, in my opinion, this unit’s mapping algorithm is not ready for prime-time–and even though the instructions have nothing to say about picking the unit up in the middle of a cleaning session, apparently doing so causes it to erase its map–something that should be mentioned in the instructions.
