Smart thermostat for sure, after that my “high end” robot vacuum dreame x50 ultra. Had a basic Roborock s5 Max before but it was bad at mopping and got stuck so often. The Dreame delivers big times. I some smart lights but they are not in the top tier list.
I have owned 2 S5 Max units for 5 years. The water pump broke on both within the first year, but that was ok because the "mopping" is the equivalent of dragging a damp wash cloth around and wasn't meeting my needs anyway.
There are much better mopping options, but the S5 Max unit is a total workhorse for vacuuming. I have relegated mine to vacuuming up cat litter before I run a Dreame vac/mop.
So I have a S5 Max that I've been using for a few years and like. Mopping isn't the best but better than nothing I suppose. Was wondering if there is a model worth upgrading to with the annual sale going on? I have carpet and hardwood and would be nice to have a self empty dock. Not really wanting to go above $400.
I bought 2 x Roborock S5 Max second hand for €150 each. All the parts are replaceable easily, sold on AliExpress etc. I installed Valetudo on it, which honestly wasn't hard. There's a tear down vid on Youtube, and it's just loads of screws. The instructions are really clear on the Valetudo page. They've been running great for 2 years now. Highly recommend.

Reliable, great mopping (lifts pads), but poor cable avoidance.
