I can also recommend Roborock brand in general because the hardware seems decent and it runs well enough with no internet/smart app required. I’ve not installed Valetudo on mine because the S4 requires some hardware changes that I’m not comfortable making. Other Roborock models are much easier to install.

Good luck!

I have a Dreame D9 flashed with Valetudo, and it's quite excellent.

Never even installed the app. Valetudo allows the machine to run locally, no calls anywhere outside the house.

Yep, as others have said, valetudo. I have a z10 pro and love it. I highly recommend one with an auto empty dust bin... Having to clean it after every run defeats the purpose of an automated vac. if you forget to empty it, it will be very ineffective the next run.

Also, I would say make sure you can assign a room for it to clean. If you have cats, automating it to clean the litter box room after they go is soooo nice

Ugh - no responses in 2 months? I hope that's not an indication that there are no such options. I'm also looking for a vacuum/mop that runs only locally. I learned of Valetudo, which might be what you're looking for - but it's too complex for me (I'm looking at the Dreametech L10s Ultra).

So no luck with roborock s7 maxV? That device looks promissing, but I never owned a robot. Can that one be fully controlled with home assistant? Is there any alternative vacuum/mopper with station for both? Looking for something like that even if its not fully offline.
