## Useworthy take

Independent testing is unusually revealing: the core vacuum is capable, while the headline arm has struggled with basic object handling and adds battery/software complexity.

## Purchase context

- Market: Global
- Price: Premium; regional pricing varies
- Work-saved potential: Medium–High
- Setup burden: Medium
- Smart premium: The robotic arm is the smart-premium test: if it cannot reliably remove enough prep work, the extra complexity is not useworthy.

## Manufacturer claims

- **Feature:** Foldable five-axis OmniGrip arm
- **Suction:** 22,000 Pa manufacturer claim
- **Height:** 7.98 cm body claim
- **Navigation:** StarSight Autonomous 2.0
