With these pool cleaners, if they are not backing up, there are several things that you could try. Lift the valve out of the water and watch the jet. It should be going on and off. If it is not, you will need to replace the back up valve. If it appears to be working properly, try adjusting your wheel RPM.

If your pool cleaners not making proper cleaning patterns on the pool floor or turning it tight circles, try checking your RPM and adjusting your thrust jets. If the RPM is higher than 32, you will need to decrease the water flow. Also, make sure that your feed hose is floating and is not becoming tangled. Finally, check the filter bag, if full it can weigh the cleaner down on one side.
