I have a 2-wheel, suction side Poolvergnugen The Pool Cleaner unit… Had it quite some time now and have maintained it carefully. According to my local pool supply lady, I’ve replaced everything that can be replaced within the last 24 months. Visually, the mechanisms all appear to be in good working condition, gears are not worn either in the gearbox, the drive shafts or on the wheels, I just bought a new set of wheel hubs and tires this year. All the driveshafts have been replaced.
My problem is the unit has no power when traveling forward. Trying to climb out of the deep end of the pool or running in to a wall cause the wheels to stop. The unit will spin around, and it does so with power… when its spinning I cannot stall the wheels by trying to grab on to the tires. Soon as its done spinning, the unit stalls again, unless it happens to be pointed downhill.
What part of the mechanism would be the cause of this kind of behavior?
