What we do when we clean Willow out is, get everything ready to use, fresh bedding, compost bag in the bin ready for the refuse, etc. Then put Willow in her ball & let her play in that while I clean the cage quickly. I always put a treat in for her to find when she gets back in to encourage her back into the cage.
Let us know how you get on - I'm sure you'll be fine, but I know you will get more confident the more you do it
