Aquabot Turbo T seems to have lost some power

I have an aquabot turbo t and today I put it in the pool and it doesn't seem like it is hugging the floor of the pool well and when it tries to climb the walls it stays on the bottom of the wall and the brushes just spin. The filter is clean but it doesn't seem like it picking up dirt very well either. It is moving and everything. Any ideas?
