As much as I like the L10su (recommended it to a friend and put Valtudo on it for him), caveat emptor: The ultrasonic sensor used for carpet detection is prone to fail. Most detect no carpet anymore (and proceed to mop it), others detect it everywhere (and don't mop anything anymore).

You should be prepared to sending it in for a warranty repair, probability for failure seems to be 5 to 10% from what I notice on the Valetudo telegram channels. Check Google for other peoples experience with Dreame repair centers. He replaced the sensor himself, but that breaks the warranty seal.

Others than that, he's absolutely happy with it.

Check https://valetudo.cloud/pages/general/buying-supported-robots... for the list of recommendations. I've a L10pro myself and it works well, too. But looking at the prices, I'd get a D10s plus or pro myself these days (that is, if the L10su wasn't an option, since it has the superior feature set; I'd be willing to take the risk with the sensor and just swap it).

Thanks! Any idea where to get the replacmemt sensor if I needed one. Also is it difficult to replace?

Uh, I think my friend ordered one locally and (because that was the last one in stock) another one for his parents from AliExpress.

I didn't do the replacement, but it seems reasonably simple - the cylindrical sensor unit has a cable with a 4 pin connector and is clipped in place.

The new one doesn't look exactly like the old one and had different makings. I hope this means it now doesn't randomly fail.
