M210 Pro

I bought it few years ago to try out a robot vacuum for cheap. It was €99 off of Amazon and it was fine for that price I would say. But really basic navigation, can be blocked really easily. Suction is ok on hard floor. For carpets it’s useless. I bought a new one this year, a real one! A Roborock Q10 S5 I got for €169 brand new and the difference is night and day.

Ive had this model for years and it works well as a set it and forget it device. It doesnt do anything fancy and the app is basic, but it does a pretty good job of randomly moving around and sweeping everything. I'm sure there are better ones out there, but for the price I think its a good buy. Its good with cat hair. I dont bother with it on carpet, it doesnt work. I just use on my hardwood.

The roller was the bane of my existence, so I got a Lefant M210. It is roller-less.

If you don’t have carpet, this is probably the best vacuum we can buy dollar for dollar

some search result remnants seem to suggest they're Xiaomi, I'd try Tuya with each type of vacuum selection (i.e. if you believe it's wifi, its also worth trying the Bluetooth options when adding a device) Also paying $300 for a vacuum that "retails for $1200" and barely comes up on google seems a bit backwards if your intention was to integrate into ha. I got my Lefant (m280 or something) for $180 new AUD, and it fuckin rules. Integrates easily as well.
