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
Shark AI Ultra 2-in-1
- ✓Large 500ml dustbin means fewer empties between self-empty cycles
- ✓Widely available at Target, Walmart, and Costco with easy returns
- ✓LiDAR navigation creates accurate maps quickly
- ✓Self-empty base is smaller and more compact than many competitors
- ✓Good US-based customer support
- ✗Mopping is basic — passive drag-style, no spinning or pressure
- ✗No obstacle avoidance means it bumps into furniture and cables
- ✗Shark app is functional but clunky compared to Roborock or Dreame
- ✗No mop lifting — mop pad must be removed for carpet-only cleaning
