I had a similar problem 2 years ago with my Aquabot Classic. Replaced the drive belts and solved the problem. I forget who I got the belts from - maybe Aqua directly.

Bad chips by: Dominik Landowski
As noted by the admin, could be bad belts/bushings. This is the most likely cause, however the driver chips could be failing. You'd need an oscilliscope and to dissect the unit until you get to the chips the measure the on waveforms. They should be a clean sin wave. Now the main processor to those drive chips begins to act up and starts throwing out a random distorted signal.
I know no cure for this besides board replacement as no one but Aqua Products has the ability to program and reflash the main processor.
Inspect the bushings/rollers/belts. If they are not damaged, I would run it till it fails, sell it for parts on fleabay and get another one.
My personal opinion is Aquabots are the best in the industry, both for design and functionality, however repair is a PITA!!! Dolphins are much easier to work on but have no way to be repaired or replaced when it comes to main boards. Parts for aquabots (besides main processor) are available and they don't remove the part numbers like dolphin does.
With that said I hope it's your belts, and I suspect it is.
Let us know!

Motor or belts by: ADMIN
The motor could be failing or the belts have an area stripped of teeth.
