Fleece does tend to draw the urine away from the surface much better than towels do. When I tried towels, I ended up having to change them three times a day to keep the surface dry. The best washable bedding I tried was something called VetBed which is a thick fleecy material designed for using with animals. It draws the urine away from the surface briliantly, so with a few sweeps up of poops in between, it's a couple of days before it needs washing.
Plus another 'con' for me (with anything washable) was that however well I brushed off the hairs, some got in the machine and clogged up the filter. Plus it was a drag doing all that washing, and if the weather wasn't nice enough to dry outside, drying was a pain too! I know it works well for some people, but it didn't suit me!
