Maybe there is no elec­tricity in the socket

• Discon­nect the robotic cleaner power supply from the socket for 30 seconds, then plug the robotic cleaner back in and switch it back on. If it still doesn't work, try another socket.

• Recon­nect the robotic cleaner cable to the power supply.

Some­thing could be obstructing the free move­ment of the drive belts, drive tracks or wheels 

• Flip the robotic cleaner upside down and try to rotate the wheels by hand, remove any debris from the drive system (hair, leaves, etc.).

The impeller could be seized by an accu­mu­la­tion of hair

• Discon­nect the robotic cleaner from the power supply. Remove the upper screws from the top of the robotic cleaner and check that the impeller does not need to be cleaned. (DO NOT use elec­tric screw­drivers for this oper­a­tion, use hand tools only).

The pH level is not correct

• Check that the pH level is between 7.0 and 7.4, correct it if necessary.
• Remove the robotic cleaner from the pool while adjusting the pH level.

The water temperature is not optimal

• Check the water temperature: if it is less than 13° C, adjust the floats depending on the robotic cleaner model.

The batteries are empty

• Check the batteries by pressing the buttons, the red indicator light on the remote control will not light up if the batteries are empty.
• Replace the remote control batteries.

The remote control is not paired with the power supply

• Pair the remote control with the robotic cleaner power supply.
• Refer to the instructions enclosed with the remote control.

Dirty filters can affect movement of the robotic cleaner

• Make sure that all the filters are clean.

The filter access hatch underneath the robotic cleaner is not closed properly

• Make sure that the hatch is closed properly.

The cable was tangled before the robotic cleaner was placed in the pool

• Make sure that the cable is spread out and untangled before placing the robotic pool cleaner in the pool.

There is too much cable in the pool

• Make sure that the cable is long enough to reach the end of the pool, but no longer than this. 
• For example, in a 10 m x 5 m pool with the power supply in the middle, do not put more than 6 m of cable in the pool.

The impeller is broken or seized by an accumulation of hair

• Disconnect the robotic cleaner power supply before carrying out this intervention.
• Remove the screws on top of the robotic cleaner and check that the impeller is not broken or in need of cleaning.
• When replacing the robotic cleaner cover, use hand tools only. DO NOT USE power tools for this intervention.

The Chlorine level is not correct

• Check the Chlorine level, make sure that it is not too high.

The cable is not long enough to reach the far end of the pool, or the cable is too tangled 

• Make sure that the cable is long enough to reach the end of the pool but not any longer than that.
• Check that the cable is not tangled.

The orientation of the robotic cleaner's handle may affect its travel under water

• Increase the diagonal angle of the handle by pressing on the handle pin and turning it.
