The real differences
Stripped of marketing. Just facts.
| Spec | roborock Qrevo Series Robot... | DREAME X40 Ultra Robotic... | Note |
|---|---|---|---|
| Suction Power | 8000Pa | 12000Pa | Dreame's suction is 50% higher, better for deep carpet cleaning. |
| Mopping System | Dual spinning mops with 10mm lift, auto mop washing and drying | Removable and liftable mop (10.5mm) with 158°F hot water self-cleaning | Both offer advanced mopping; Dreame allows mop removal for carpets, Roborock has continuous spinning. |
| Navigation & Obstacle Avoidance | PreciSense LiDAR + Reactive Tech obstacle avoidance | 3D structured light + camera + LED light | Both are highly accurate; Dreame's camera can recognize more objects, but LiDAR is reliable in dark. |
| Noise Level | 64 dB | 70 dB | Roborock is noticeably quieter during operation. |
| Battery Capacity | Not specified (180 min runtime) | 6400 mAh (180 min runtime) | Both offer similar runtime; Dreame's larger battery may degrade slower. |
| Tangle-Free Brush | Asymmetrical side brush and full-rubber main brush (0% hair tangling certified) | Standard brush with liftable side brush (no specific anti-tangle claim) | Roborock's SGS-certified design reduces hair tangling significantly. |
| Weight | 33.49 lbs | 28.7 lbs | Dreame is lighter, making it easier to move the dock if needed. |
