Maybe one way of cleaning the room would be to remove everything but the large furniture, put the removed stuff into a room you are not using. Before taking it back, go thru it and decide does it really need to go back.
Make a place to fold fabric - cutting table and take a few pieces in at a time, fold and put them away before bringing in any more.
I put the books back into the room first after the big removal. Then the fabric and put it away.
