Your robot climbs because pump suction holds it to the wall while the drive system propels it up the wall.
If wheels and treads are moving smoothly with NO wheel hesitations but robot won't climb...
A. CHECK THE IMPELLER! Remove the cap on top of the robot and remove all hair or other obstructions. If the pump can't pull enough water, your robot won't climb to the waterline.
B. Replace the rubber treads
C. Clean the Bag
If the wheels are moving intermittently, or in a halting manner, then change the
, all 4 bushings on the drive side...that's one each for the wheels and 2 for the drive gear that turns the belts and change the stepped rollers. Thats 4 bushings, 2 stepped rollers. 2 belts.
Less likely but possible is a worn drive gear. Scroll down to ROBOT NOT MOVING for more information'
Look at the wheel axles that sit in the bushings. If they look like the wheel on the right (below), replace the wheel.
AQUABOT IS DEAD IN THE WATER
If BOTH pump and motor are not working, (Pool cleaner is not pumping water or moving) then the problem is most likely electrical Troubleshoot the power supply
1) Reset your GFI outlet and test the outlet for power with a multimeter on the Vac 200 setting or plug a small appliance into the outlet.
2) Press the reset (if equipped) on the Power Transformer and check the fuse. Some transformers have a reset switch that must be pushed every time the machine is started.
3) Check for voltage at the Power Transformer with a multimeter set to Vac 200. Replace the transformer if no voltage is detected.
Aquabot Troubleshooting-The transformer: case open and UNPLUGGED.
I say again, DO NOT PLUG IN the transformer with the case removed.
NEVER do a continuity check with the power on.
a)Perform a continuity check on the reset button by holding a probe on each terminal and holding in the reset. Continuity should be there when the button is pressed. If not, replace the reset switch
b)Perform a continuity check on the fuse holder.
c)Perform a continuity check of the on/off switch.
If the transformer is OK, on to step 4.

4) With the robot submerged, wiggle the cord between the handle and the motor. If the robot momentarily comes to life,
replace or repair the cord.
Check the cord plug end for broken contacts. Replace the plug if needed. May be checked with a continuity test on the multimeter.
5) BE SURE THE PLUG IS IN ALL THE WAY!
PUMP IS WORKING, POOL CLEANER WILL NOT MOVE.
1) Look for a broken or loose slipping drive belt. Be certain the belts are routed properly over the stepped rollers.
2) Be sure the sideplate bushing that holds the drive shaft is intact.
3) The drive shaft has a plastic coated end that inserts into the bushing. If the plastic is gone, replace the drive shaft assembly
2) With the robot submerged, check to see if the drive gear is turning. If YES,
replace the belts.
If NO, check that the pin pressed into the axle to turn the drive gear is still there. SEE BELOW PHOTOS.
As a LAST resort do number 3
3) Remove the robot from the water and lay upside down. Turn on the robot for a maximum of ONE minute. Turn a wheel a little in each direction to unbind the motor.
