Roborock S8 MaxV Ultra vs Roborock Qrevo Curv
Quick take: The Roborock Qrevo Curv costs $100 less; the Roborock Qrevo Curv has stronger suction (18,500 vs 10,000 Pa); the Roborock Qrevo Curv runs longer per charge (240 vs 180 min).
Which one to buy
Spending $100 more on the S8 MaxV Ultra buys one thing the Qrevo Curv can't match: obstacle avoidance owners trust. S8 owners say it dodges shoes, cables, socks and dog toys consistently enough to leave running unsupervised around pets. Curv owners say the opposite about cords, their top complaint: it runs into them, gets confused and drags them, so they tidy before every run.
On almost everything else, the cheaper Curv matches or beats the older flagship. Both have hot-water mop washing, dual-roller-style brushes that resist tangling, and mop lifts that keep medium-pile carpet dry. The Curv is rated at 18500 Pa against 10000 Pa and at 240 minutes against 180, its split DuoDivide brush posted a perfect zero-tangle result in pet-hair testing, and its AdaptiLift chassis climbs 4cm thresholds. Owners describe spotless hard floors and full coverage in homes over 3,600 sq ft. Its soft spots are pet hair on rugs, which is only okay, and a handful of defective units out of the box.
S8 MaxV Ultra owners praise its carpet pickup of litter and fine dust and the per-room suction and mop settings. They grumble about a massive dock, refilling the tank every 3-4 cleans, a thin strip missed along baseboards, and rubber rollers that can fling small toys across the room. Its app also has a steep learning curve.
Both are now discontinued (Roborock's replacements are the Saros 20 Flow at $1500 for the S8 MaxV Ultra and the Qrevo Curv 2 Flow at $700 for the Curv), so this is a leftover-stock choice. The Curv is the better buy for most homes, and the clear one if you have raised doorways. The S8 MaxV Ultra earns its extra $100 only where the floor is never clear of cords and toys and nobody is going to pick them up.
Roborock S8 MaxV Ultra
Now discontinued, but worth the extra $100 if your floors always have cords, socks or pet toys on them, since owners trust its obstacle avoidance to run unsupervised.
Roborock Qrevo Curv
Now discontinued, but for most homes, and especially ones with raised doorways or long-haired pets, it's the stronger cleaner for $100 less, provided cords get picked up first.

Roborock S8 MaxV Ultra vs Roborock Qrevo Curv: common questions
Is the Roborock S8 MaxV Ultra's obstacle avoidance worth $100 over the Qrevo Curv?▾
Only for a cluttered home. S8 MaxV Ultra owners describe its avoidance as reliable around shoes, cables and pet toys. Curv owners say cords are its main weakness, while homes without floor clutter report almost no interventions, so a tidy household doesn't need to pay extra.
Can the Qrevo Curv climb thresholds the S8 MaxV Ultra gets stuck on?▾
That's its signature feature. The Curv's AdaptiLift chassis raises the body over thresholds up to 4cm and onto thick rugs, and owners of older homes with raised doorways cite it as their reason for buying. The S8 MaxV Ultra has no comparable climbing chassis.
Which robot has the bigger dock to make room for, the S8 MaxV Ultra or the Qrevo Curv?▾
S8 MaxV Ultra owners describe its dock as massive, with several rearranging furniture to fit it. The Curv's rounded dock looks less like an appliance but takes up about as much space as boxier rivals, so measure for either.
