If your robot is not climbing walls, this can be normal behavior depending on several conditions.

🔋 Battery level

Wall climbing depends on the battery level:

• The robot climbs walls mainly when the battery level is above ~65%
• When the battery level drops:
  • The robot prioritizes floor cleaning only

👉 This is expected behavior to optimize cleaning efficiency.

⚙️ Selected cleaning mode

Make sure the correct mode is selected:

• Floor only mode → no wall climbing
• Wall or Floor & Walls modes → wall climbing enabled

👉 Wall climbing only occurs in the appropriate modes.

🏊 Pool conditions

Wall climbing performance may be affected by:

• Very smooth or slippery surfaces
• Algae or dirt on the walls
• Irregular shapes or obstacles

👉 Clean surfaces improve climbing performance.

🧹 Robot condition

Check that the robot is in good condition:

• Filters not clogged
• Brushes clean and not worn
• No debris blocking movement

⚠️ Important

• The robot does not climb walls continuously during the entire cycle

• Wall climbing typically occurs at the beginning of the cycle, when battery level is higher

• Reduced wall climbing later in the cycle is normal behavior, not a malfunction

• The robot does not climb walls at the end of the cleaning cycle

• At the end of the cycle, the robot:

  • moves to the waterline for retrieval
  • waits for a short period
  • then switches off

👉 This movement to the waterline is not a wall-cleaning phase, but a normal end‑of‑cycle behavior.

✅ In summary:
Wall climbing depends on battery level, selected mode, and pool conditions. Reduced climbing is often normal behavior, not a fault, and the robot does not climb walls at the end of the cycle.
