Both brands clean well. They differ in navigation philosophy, mopping, and how much ongoing fiddling they demand.
Quick verdict
- Roborock — better navigation, better mopping, more settings to tune
- Roomba — simpler, more reliable obstacle avoidance, less capable mop
Head to head
| Roborock (placeholder) | Roomba (placeholder) | |
|---|---|---|
| Navigation | LiDAR + camera | vSLAM camera |
| Mapping speed | Fast, accurate first pass | Slower to build, improves over runs |
| Max suction | placeholder — higher Pa | placeholder — strong but lower |
| Mopping | Vibrating / sonic scrubber | Basic pad drag |
| Obstacle avoidance | Good, occasional cable issues | Best in class |
| App depth | Very detailed | Clean, limited |
| Self-empty dock | Widely available | Widely available |
Navigation
Roborock maps faster and cleans in straighter, more efficient lines. Roomba takes a few runs to settle but is less likely to get stuck on cables and shoes — its obstacle avoidance is the best we have tested.
Mopping
This is not close. Roborock’s scrubbing pad removes dried spills; Roomba’s pad mostly spreads moisture around. If hard floors dominate your home, that alone decides it.
Maintenance and consumables
| Item | Frequency | Notes |
|---|---|---|
| Dust bag | 4–8 weeks | Both brands, similar pricing |
| Filter | 2–3 months | Washable on both |
| Brush roll | 6–12 months | Rubber rolls resist tangles better |
| Mop pad | 2–3 months | Roborock only |
