I LOVE having the hayloft, and so do my boars. I use fleece on the bottom level and if they spent all their time down there cleaning would be a nightmare. I use fitted liners in a covered cage, so pulling them out to shake is too difficult, and I rely on vacuuming.
In the hayloft, I use towels under newspaper. They spend most of their time up there eating (pigs!), so most of their wee etc. ends up there. It's super quick to roll up the newspaper, lay new stuff down, and put down hay every other day. Meanwhile, the fleece only needs a quick vac a few times a week, and a complete change every 7-10 days. I get SO much longer out of my fleece.
So in a way, I think it ends up being LESS work for me. That wouldn't be the case if you used fleece or something in the loft, but if you use newspaper and hay, or some other disposable bedding, that you can just roll up and toss in the bin, it takes seconds.
