in fact with long haired the fleece is a blessing! their fur is absolutely clean (my Calliope is a bit dirty because she uses to wee after walking backwards and her long hair sometimes is wet in her butt).
I also sweep up, not because of their bedding, but because they spend long time on the floor where I put a box with the hay. Then it happens that we put a foot into the cage for lifting the piggies... and poo remains stuck under the sole or on the floor tile. I want to say: the mess is caused by our carelessness, not the bedding itself, which works perfectly and remains dry. The only wet part is some sport under the fleece, usually always in the same corners and you need to remove the wet paper.
I have 4 pieces of fleece (one is not good, though). I remove once a day the fleece and I hang it out the balcony (if it is raining I don't do that). My piggies in the meanwhile are strolling in the kitchen. Then I arrange again the cage with the same fleece. I change it after 3-5 days... sometimes only for changing the colour of the cage. Then I wash all the fleeces together (after a spinning 1200rounds they come out almost dry). I can put fleece in washing machine even with normal laundry. For sure I don't switch on washing machine only for washing the fleece! the machine starts when it is filled with clothes to be washed. Fleece can be washed once a week, too. It works as a filter, it is clean and needs to be shaked only for removing hair.
Puppy pads of course work fine, too, but I prefer saving my money considering that I don't spend anything for getting free supermarket leaflets (they are left here in my building, but I can take tons of them even at the check out of the supermarkets). Maybe puppy pads last more days, I don't know... and you should remove the poo on the fleece...
Look, I hate cleaning up the house, but for shaking the fleece with poo and leftovers on the floor, sweeping up everything, removing the wet leaflets and cover again with the fleece I need only 3-4 minutes...
I add some useful picture of this daily job:

as you see, nothing special...
