Several possibilities to consider...
How old is the filter bag and is it clean?
Older bags or bags not thoroughly cleaned can resist water passing thru them to the point there is not enough downward pressure to allow the unit to 'bite' the pool surface and climb.
How worn are the brushes and tracks?
Worn brushes and tracks will slip once worn enough. Replacing them could fix the problem.
Is it trying to climb or does the unit start up the wall and immediately reverse?
If your motor has been replaced new style motors spend far less time climbing assuming most debris will instead be found on the pool floor. If it has not been recently replaced the program within the motor may be failing.
What is the condition of the pool?
Low water temperatures and/or algae can cause the unit to slip in place and as a result it will not climb. Eventually it will scrub enough to gain traction and will slowly progress up the wall. For temperatures below 70 degrees the unit will find in more and more difficult to climb the lower the temperature.
What material is the pool surface?
Some linered pools and fiberglass pools require climbing rings in the brushes. Do you have those? If so, what condition are they in? Worn rings or missing rings will prevent climbing those and other smooth pool finishes.
