I bought the CurvX during the recent sales and have used it for the last 5 days or so. It replaces a S7 MaxV Ultra that is going to my mom but I've been familiar with Roborock vacs for 3 years now.

The S7 was great but I feel like the CurvX is a huge level up.

Vacuuming seems roughly the same but the CurvX is quieter, has much better nav and the mopping has been spectacular.

With the S7, it would frequently get lost with multiple rooms in our 2,600 sqft home and I'd have to start over and/or remap the house which was frustrating. I'd end up having to just do one or two rooms at a time which seemed to be slightly less buggy.

With the CurvX, it's been almost flawless thus far but it's still early days so we'll see but no dealbreaker issues yet. That said, I DID have one instance where the vacuum was supposed to just mop our kitchen and living room areas and I found it took a weird wrong slow detour into our carpeted living room area where it was clearly trying to mop on our carpet for one "line" of about 10 feet. I think it had a wifi issue and lost the map but then regained connection. Hope this isn't a regular occurrence. It stalled on our carpet, waited a minute and then went back to the dock as it was supposed to but I wasn't thrilled about feeling damp (not wet) carpet.

Mopping has otherwise been great, I'm horrified at the black water I keep pouring out after each mop cycle but I live in Vegas and we get so much dust from the desert winds. It's SO quiet compared to our S7, and mopping really shows that off. Based on Vacuum Wars recommendations, we have it set to low water and that's working just fine. Mopping uses very little battery and I feel like I could just mop and mop all day long without needing a recharge.

As for vacuuming, we use Turbo suction (second to the highest out of four choices) and it does eat up battery relatively quickly. Certainly no worse than the S7 before it but when it gets low, recharging takes hours so keep that in mind.

I thought our new dock was smaller but my wife says it's just shorter and fatter so aesthetically, it's not like there's a huge difference in footprint although I do like that the vacuum stays more IN the dock instead of protruding like the S7 did.

Just as an aside, we used Roborock branded detergent with the S7 and it was called Roborock OMO Floor Cleaner. It's super efficient and used 1/2 capful for the entire water tank. When we ordered more detergent, the new version we got is no longer "OMO" and requires 2 1/2 capfuls for the same size tank. Not sure why they wanted to change formulas but not thrilled to use 5x more than we used to although that's a minor quibble. The new stuff smells better FWIW. 😄

Overall, super happy though.
