Roborock Q Revo MaxV vs Roborock S8 Pro Ultra
Quick take: The Roborock S8 Pro Ultra costs $230 less; the Roborock Q Revo MaxV has stronger suction (7,000 vs 6,000 Pa).
Which one to buy
Both Roborocks are now discontinued: the S8 Pro Ultra's successor is the Saros 10R at $900, and the Q Revo MaxV's is the Qrevo 2 Pro at $650. At $470 the S8 is $230 less than the Q Revo MaxV, but either way you're buying leftover stock of a retired model.
On the merits, the two split cleanly. The S8 Pro Ultra has dual rubber brushes, and its owners report zero tangling even with several pets, while Q Revo MaxV owners complain that its bristle-and-rubber brush wraps long hair. The MaxV answers with three things the S8 lacks: a camera for obstacle avoidance that owners say reliably dodges cables, shoes and pet toys; a hot-water dock; and dual spinning mop pads that press hard enough to lift dried spots. S8 owners say it runs into shoes, cables and pet bowls, that its cold-water dock leaves the pads musty after a few weeks unless you clean it monthly, and that its sonic mop can't handle dried or sticky spills. Its 5mm mop lift isn't enough for high-pile carpet either.
Neither is a thick-carpet machine. They're rated at 7000 Pa and 6000 Pa, MaxV owners notice the drop on high pile, and S8 owners say it struggles with debris embedded in thick carpet.
For a long-haired, multi-pet home with floors kept clear, a discounted S8 Pro Ultra still does the vacuuming half better, and $230 is real money. For everyone else, the MaxV's camera and stronger mopping made it the one to get, and anyone who wants a model still in Roborock's lineup should look at its successor, the Qrevo 2 Pro.
Roborock Q Revo MaxV
For a home with cables, shoes and pet bowls on the floor, or dried spills to mop, it handles both, though it is now discontinued with the Qrevo 2 Pro as its successor, with a hot-water dock that keeps pads fresh.
Roborock S8 Pro Ultra
Worth it only as a discounted leftover for a multi-pet, long-hair home with clear floors, accepting that it's discontinued and washes its pads in cold water.

Roborock Q Revo MaxV vs Roborock S8 Pro Ultra: common questions
Is the discontinued Roborock S8 Pro Ultra still worth buying over the Q Revo MaxV?▾
Only at a clear discount and only for the right home. Its dual rubber brushes are its best feature for pet hair, but it has no camera, no hot-water washing and a weaker mop. Since it's discontinued, factor in that you're buying a retired model when the $230 saving looks tempting. The Q Revo MaxV is discontinued too, replaced by the Qrevo 2 Pro.
Which is better for long pet hair, the S8 Pro Ultra or the Q Revo MaxV?▾
The S8 Pro Ultra. Its owners report zero tangling from the dual rubber brushes even in multi-pet homes. Q Revo MaxV owners say its bristle-and-rubber combo brush tangles with long hair more, though it otherwise handles daily pet hair on hard floors well.
Does the S8 Pro Ultra's dock get smellier than the Q Revo MaxV's?▾
Its owners say so. The S8 washes pads with cold water, and they report a musty smell after a few weeks unless the dock is cleaned monthly. The Q Revo MaxV washes its pads with hot water, which owners credit with keeping them fresh without manual work.
