Roborock S8 Pro Ultra vs Roborock Qrevo S
Quick take: The Roborock Qrevo S costs $20 less; the Roborock Qrevo S has stronger suction (7,000 vs 6,000 Pa).
Which one to buy
Both of these Roborocks are discontinued, so this is a choice between two leftovers $20 apart, and the right one depends on whether your bigger mess is hair or floors that need mopping. They share a lot: no camera, docks that self-empty and wash pads in unheated water, a 180-minute battery and the same app. Owners of each say cables and pet bowls must come off the floor first.
The S8 Pro Ultra, at $470, is the hair machine. Its owners report zero tangling from the dual rubber rollers even in multi-pet homes, and say it's strong on hard floors and low-to-medium carpet. Its mopping is a vibrating pad at 3000rpm that handles daily dirt but not sticky spills, and its 5mm lift is too low for high-pile carpet.
The Qrevo S, at $450, mops better. Owners call its mopping great, its spinning pads lift over carpet with a 10mm lift, and they go weeks hands-free. Its weaknesses are vacuuming ones: weak on carpet, especially patterned carpet, and long pet hair can jam its intake, with one owner returning theirs because the auto-empty couldn't move heavy dog hair.
For a shedding dog or several cats, the S8 Pro Ultra is the safer leftover. For a mostly hard-floor home with light shedding, the Qrevo S mops better for a little less.
Roborock S8 Pro Ultra
For a home with heavy shedding, its dual rubber rollers are the deciding feature, as long as you accept buying a discontinued model.
Roborock Qrevo S
Suits a tidy, mostly hard-floor home with light shedding that wants better mopping and a higher 10mm mop lift, knowing it's also discontinued.

Pros & cons
Roborock S8 Pro Ultra
- ✓Dual rubber brush system excels at picking up pet hair without tangles
- ✓Self-washing dock eliminates the grossest part of robot mop ownership
- ✓Sonic mopping vibrates at 3000rpm for surprisingly effective floor cleaning
- ✓Excellent multi-floor mapping — remembers up to 4 floors reliably
- ✓Consistently strong owner sentiment across thousands of verified reviews
- ✗No camera means it can bump into small obstacles like shoes or cables
- ✗6000Pa suction struggles with heavier debris on thick carpet
- ✗Dock does not use hot water, so mop pads can develop odor over time
- ✗VibraRise mop lift is only about 5mm, not enough for high-pile carpet
Roborock Qrevo S
- ✓Highest recommendation count in owner-community polls — 82% positive across 247 owners
- ✓Complete dock (self-empty, mop wash, hot-air dry, water refill) at a price rivals charge for empty-only
- ✓Dual spinning mops at 200RPM outclean the drag-pads on same-price competitors
- ✓Roborock app maturity: no-mop zones, per-room routines, multi-floor maps
- ✓10mm auto mop lift handles low and medium carpet transitions
- ✗No camera-based obstacle avoidance — pre-tidy cables and pet toys or it will find them
- ✗Mop washing uses unheated water, so pads need an occasional manual deep clean
- ✗7000Pa suction is fine for daily cleaning but not deep carpet extraction
- ✗Single rubber roller tangles with very long hair more than the DuoDivide brushes
Roborock S8 Pro Ultra vs Roborock Qrevo S: common questions
Are the Roborock S8 Pro Ultra and Qrevo S both discontinued?▾
Yes, both are. You're choosing between remaining stock of two retired models, each with a 1-year warranty. That makes a current robot worth a look too, but between these two the choice comes down to pet hair versus mopping.
Which handles heavy dog hair better, the S8 Pro Ultra or the Qrevo S?▾
The S8 Pro Ultra. Its owners report zero tangling from the dual rubber rollers in multi-pet homes. Qrevo S owners say long pet hair can jam the intake, and one returned theirs after the auto-empty couldn't handle heavy dog hair.
Does the Qrevo S mop better than the Roborock S8 Pro Ultra?▾
Owners suggest so. The Qrevo S uses spinning pads that owners call great at mopping and lifts them 10mm on carpet. The S8 Pro Ultra's vibrating pad handles daily grime but not dried or sticky spills, and its 5mm lift is too low for high-pile carpet.
