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 Amazon ratings with 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
