5. Operation
5.1 Placing the Robot in the Pool
Gently lower the ULTRAMARINE P1 into the pool. Ensure it is fully submerged and air bubbles have escaped before starting a cleaning cycle. The robot will sink to the bottom.
5.2 Cleaning Modes and Settings
The ULTRAMARINE P1 offers versatile cleaning options controllable via the ECOVACS app:
- Floor Cleaning: Focuses solely on cleaning the pool floor.
- Wall Cleaning: Cleans pool walls and the waterline.
- Full Pool Cleaning: Provides comprehensive cleaning of both the pool floor and walls.
You can also adjust the suction power (Eco, Standard, Max) through the app to match the debris level and desired cleaning intensity. The robot provides up to 180 minutes of continuous operation in Eco mode, covering up to 180 m² on a single charge.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ULTRAMARINE P1.
6.1 Cleaning the Dual-Layer Filter
The ULTRAMARINE P1 features an innovative dual-layer filtration system. Regularly clean both the 180 µm outer mesh and the 3 µm inner filter to maintain optimal suction performance and water clarity.
- Open the robot's cover and remove the filter basket.
- Separate the outer mesh from the inner fine filter.
- Rinse both filter components thoroughly with clean water to remove all trapped debris.
- Ensure filters are completely dry before reassembling and placing them back into the robot.

6.3 Storage
When not in use for extended periods, clean the robot thoroughly, ensure it is dry, and store it in a cool, dry place away from direct sunlight and extreme temperatures. It is recommended to partially charge the battery (around 50%) for long-term storage to preserve battery health.
7. Troubleshooting
If you encounter issues with your ULTRAMARINE P1, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot not moving or stuck | Low battery; debris obstructing brushes/wheels; excessively slippery pool surface. | Charge the robot fully. Check and clear any debris from brushes and wheels. Ensure the pool surface is suitable for robotic cleaning. |
| Poor cleaning performance | Clogged filter; low suction power setting; blocked suction channel. | Clean the dual-layer filter thoroughly. Increase suction power in the app. Check for and clear any blockages in the robot's suction path. |
| App connection issues | Bluetooth off; robot out of range; app glitch. | Ensure Bluetooth is enabled on your smartphone and the robot is nearby. Restart the app and the robot. Try re-pairing the device in the app settings. |
| Robot not climbing walls | Low battery; dirty brushes; algae on pool walls. | Ensure the robot is fully charged. Clean the roller brushes. Address any algae growth on pool walls. |
