Rule out the obvious causes of poor vacuum first. Make sure the water level in the pool is sufficient and air is not being sucked in through skimmer inlets.

Also, how do I fix the suction on my pool vacuum?
Accordingly, what is the most common symptom of a pump suction leak?
Besides, why is my automatic pool vacuum not moving?
If your robotic pool cleaner stops moving, check the power cord. It may not be plugged in properly or there may be a problem with the power supply. Check the power supply to make sure the indicator light is on. If it is and the pool cleaner is still not moving, then the problem lies with the cleaner.
