First, please check whether your pool robot is fully charged and switched on.
Inspect the pool for possible obstacles such as ladders, severe liner wrinkles, or other objects where the pool robot could get stuck. Uneven pool floors or pronounced wrinkles may negatively affect the cleaning performance and driving behavior of the device. If necessary, the cleaning brushes/lips can be removed to reduce the risk of the robot getting caught on the pool liner.

A common cause of malfunctions is dirt or debris inside the device. Hair, fibers, or similar residues can block the water outlet nozzle, propeller, impeller, pump shaft, rollers, or the base plate. This can significantly reduce the pump performance, causing the cleaner to clean poorly, stop rotating, or remain stationary.

Therefore, regularly clean:

• the filter unit and debris flap,
• the water outlet nozzle and propeller,
• the impeller and shaft,
• the rollers or wheels,
• as well as the device’s base plate.

Dirt between the upper housing and the water outlet nozzle can often be removed using a water jet, for example from a garden hose. To thoroughly inspect the impeller and shaft, the motor unit must be removed.
If the measures listed above do not resolve the issue, there may be a defect in the motor unit or the base plate. You can find a tutorial for replacing the motor unit at the following link.

This is not a technical defect and is completely normal. The pool robot starts its cleaning cycle with a short delay and begins moving and cleaning automatically about 15 seconds after being switched on in the water. This brief waiting time is necessary for the correct startup process of the device in the water.

The pool robot beeps when the ON/OFF button is pressed outside the water. This is due to the integrated water sensor. Put the pool robot into the water and after 15 seconds it will start cleaning the pool.

If your pool robot does not reach all areas of the pool, this is usually not due to a defect, but rather to its operating principle and usage conditions. The pool robot moves in a random pattern, so complete pool coverage depends on running time. In larger pools, it may happen that after one cleaning cycle some areas are not yet covered.

• Switch off the filter pump shortly before and during operation of the pool robot. This allows dirt particles to settle on the pool floor, enabling the cleaner to work more efficiently.
• It is also recommended to clean the debris container before each cleaning cycle, as contamination can also reduce cleaning performance.
• Increase the cleaning time to give the robot sufficient time to clean all areas of the pool.
• For battery-powered devices, it is recommended to fully charge the pool robot before use to ensure maximum cleaning performance.
• For cable-connected devices, make sure that enough cable is placed in the pool so the cleaner can reach all areas. At the same time, only place as much cable into the water as necessary to avoid twisting of the floating cable.
• Depending on the model, you can also adjust the nozzle or wheel settings. This changes the cleaning radius and helps the robot reach different areas more effectively. Please always refer to the user manual for correct adjustment instructions.

By following these measures, you can significantly improve cleaning performance and achieve better overall pool coverage.

If your pool robot does not sink properly, moves in circles, or stops at the pool wall during cleaning, this is usually not caused by a defect, but rather by trapped air inside the device, dirt buildup, or water conditions.

Please check the following points:

• Before starting, the pool robot should be fully submerged to allow all trapped air to escape from the housing. Place the device into the water at a slight forward angle and briefly turn it upside down afterwards so that all enclosed air can fully escape. This ensures optimal contact between the wheels and the pool floor, allowing the cleaner to operate reliably.
• If air remains inside the device, the pool robot may float up, move in circles, or stop at the pool wall.
• Another common cause of malfunctions is dirt or debris inside the device. Hair, fibers, or similar residues can block the water outlet nozzle, propeller, impeller, pump shaft, rollers, or the base plate. This can significantly reduce pump performance, causing the cleaner to work poorly or stop moving completely.

Therefore, regularly clean:

• the filter unit and debris flap,
• the water outlet nozzle and propeller,
• the impeller and shaft,
• the rollers or wheels,
• as well as the device’s base plate.
   
• Please also check the salt level and pH value of your pool water and adjust them correctly if necessary, as water conditions can also affect the driving behavior of the cleaner.
• If the pool cleaner only moves vertically in the pool even after all air has been removed from the device, additional weighting of the cleaner may be required. In this case, please contact our service center.
