As far as I know, the Dream x50 does not use Matter protocol because it cannot communicate with other smart devices. We simply operate the Dream with the smartphone and the Dream APP from home or when we are not at home.

The cleaning experience is very good, but the emptying function keeps causing problems because the water in the lower container is not sucked out. The reason seems to be the insertion of the dirt container or a blockage caused by dirt, which I have not yet been able to see. In other words, although I think everything is inserted correctly and not blocked, this error log keeps coming up, which means that the cleaning plate has to be cleaned and dried by hand.
Apart from that, the appliance has worked great so far.
The error mentioned above was there from the start. For me, it's a bit of a game of chance, as I always insert the container carefully and this error then occurs. Fortunately not that often.
