## Useworthy take

Multiple hands-on tests support a low-maintenance ownership story, while also showing mopping misses and occasional rescue events. That makes it a useful Set-and-Forget benchmark.

## Purchase context

- Market: Global
- Price: €1,499 EU MSRP reported by reviewers; regional pricing varies
- Work-saved potential: High
- Setup burden: Low
- Smart premium: The premium is mainly for fewer stuck events, better obstacle handling and automated dock maintenance—not merely suction.

## Manufacturer claims

- **Suction:** 36,000 Pa manufacturer claim
- **Thresholds:** Adaptive lift chassis; up to 8.8 cm double-layer claim under specified conditions
- **Navigation:** StarSight Autonomous System 2.0
- **Dock:** Automated wash/dry/empty functions
