I love this little vacuum for picking up piggy poo -- and with seven piggies, we have a lot of poo! However, it doesn't do as well with hay, because it clogs the nozzle and/or the container fills up too fast. I confine hay to the lofts and use a dustpan and brush for those areas for daily spot cleaning. But in the rest of the cage I vacuum the fleece flippers daily with this little wonder. Using it on poo makes the filters get filthy more quickly than household vacs (and I use it only for the piggy poo), but you can buy new filter sets easily on Amazon.
