Select a cleaning mode:
- Press the Mode button to cycle through available modes.
- Alternatively, open the app, choose a mode, and tap Start.
  
  Mode Coverage
  
  Waterline cleaning Waterline and corners
  
  Surface cleaning Water surface only
  
  Combo cleaning Waterline and water surface
Place the robot into the pool, and it will begin cleaning automatically.
Note: The robot will clean until the battery runs low. If there is sunlight, it will recharge itself and continue cleaning.

Retrieve the Robot

To finish cleaning, activate Remote Mode in the app and tap Park to bring the robot to the poolside.
Important: Ensure that both your phone and the robot are connected to the same Wi-Fi network with a strong signal. For Bluetooth control, keep your phone within 10 m of the robot.

Note: You can also use the directional controls in the app to guide the robot to an accessible location for retrieval. Use the retrieval hook if needed.

Eco Mode
When the battery level drops below 20%, the indicator light turns orange, and the robot switches to Eco Mode. In this mode, the robot works intermittently. Only the debris intake impeller and propellers remain active to conserve power.
If sunlight is available, the robot will use solar tracking to move to a sunlit area in the pool for charging. Once sufficiently charged, the robot will resume its previous cleaning task.
Note: Eco Mode is automatically managed by the robot and requires no manual intervention.

Anti-stranding Bars

When to use: Deploy the anti-stranding bars if the pool has shallow steps or obstacles that may trap the robot.

How to use: Rotate the bars outward to activate them. To retract, rotate them back into place.
