It arrived. It doesn't even start. I charged it. Nothing. It only shows it has power when it's on the charger. It will be returned immediately as Dead on Arrival. You might be luckier...
Update. The store repaired it and now it works. The good: it's thin and fits under furniture. It doesn't require an internet connection, so it doesn't send information about your home to China!!! The bad: It's not the smartest robot in the world! Nor the quietest! But it picks up dog hair very well.

Oh no, it's not quiet at all! It makes quite a noise. Yes, it goes through all the areas, but you can't really call it cleaning when it blows the dust around and takes it elsewhere. When you manually press it to return to the base, it takes about 10 minutes to wander around for no reason and then returns. The mapping it does is ridiculous and the display is like a child's drawing. You can't select a specific room for cleaning. If you have a pet, it's satisfactory for the most part, but you still don't really care about the rest

I have it for over 5 years. We're talking about a dog, it still works and operates like the first day. Of course, it has been surpassed by now and I think you can find much better ones.
The downsides are that it doesn't connect to wifi and doesn't do mapping, resulting in it wandering randomly in the space and not going everywhere.

Just after the two (2) year warranty expired, the suction motor broke and there are no spare parts available... The robot vacuum cleaner is useless and its price increases without any spare parts
