Dreame L20 Ultra
★ STRENGTHS
- Obstacle avoidance repeatedly verified by owners: cords (even on carpet), shoes, plants, and pet waste
- Strong autonomy: self-maintaining dock, AI Clean Genius mode, optional water/drainage hookup kit
- App transparency: photos of detected obstacles plus a misidentification feedback loop
✗ WATCH OUT
- $1500 list price; observed buy prices $945-$1050 make value discount-dependent
- One 9-month owner reports declining cleaning, mop-pad docking failure, and no fix via factory reset
- After-sales service rated very poorly by the only long-term owner
Roborock S8 Pro Ultra
★ STRENGTHS
- Highly reliable mapping and navigation compared to older iRobot models
- Autonomous mopping system is highly effective for hard floors
- Mop pads are easily removable and washable
✗ WATCH OUT
- The all-in-one docking station is extremely large
- Obstacle avoidance is considered lackluster for a flagship device
- High flagship price point implies a steep investment
