If the hooks on the sander are getting gummed up with fuzz so they don't work anymore, you could try cleaning it with a file card. You know those flat metal toothed brushes for cleaning files. You should be able to get one a any hardware store if you don't have one already. A good thing to have around regardless.

: Hi,
: I am doing my sanding with my ROS sander. After a half hour of sanding the
: loop and hooks break off and the disc comes off for good. Is this what
: happens to these things for everyone? And is there any good way to take
: the cottony residue left on the sander from the disc. Also, can the disc's
: be reaplied using a spray contact glue or will that mess up the sander's
: loops or hooks.
: Thanks
