He sounds to be doing quite well overall although it's up & down, the cage clean may have disturbed him a bit & been the reason for the sudden activity.
I would remove any levels or areas he might fall from even if he does still have active spells keep things as flat & level as possible.
If he's having trouble grooming then you can gently bath any matted fur with cotton wool just damp with warm water, you don't want him to actually get wet.
