## Useworthy take

CHIP finds excellent cleaning and a useful service station, while the category still faces weight, setup and supervision constraints that normal spec sheets underplay.

## Purchase context

- Market: Europe / Global
- Price: About €500–€600 class in recent EU testing
- Work-saved potential: Medium
- Setup burden: Medium–High
- Smart premium: The station improves pad care, but a window robot only wins if per-pane setup and supervision do not consume the time it saves.

## Manufacturer claims

- **Station:** Vortex Wash / pad-cleaning station
- **Cleaning:** Multi-nozzle spray + microfiber cleaning
- **Power:** Portable station + tethered safety workflow
- **Control:** App / connectivity
