Actually works in the dryer!
This works great, though not in the way I anticipated.  I stick the two half spheres to the inside drum of my dryer and dry a load as I normally would. After the cycle I remove and wash all the pet hair off the the half spheres (not letting it go down my sink), and place the half spheres on a rack to dry for the next drying cycle.  We’ve tried a lot of washer / dryer products, but this is the only one that actually works!
