I have a roomba 530 pet series. It appears that the brushes aren't turning. They are free of dirt and debris and move easily when manually turned. But, You can tell there may not be a motor turning, because the roomba is more quiet than normal when you turn it on. Also, the hair just collects along the bottom of the brush and doesn't get pushed into the bin

The belt either broke or has come off the track.... this should be easily accessable from the underside of vaccuum

No belt..
Roomba has a number of modules that can be replaced, including its drive
wheels, side brush, main cleaning head, vacuum bin, caster wheel, and
battery.
To access Roomba’s replaceable modules, remove the bottom cover of
Roomba by removing the four screws that hold down the bottom cover and the
screw that holds the spinning side brush.
try removing/replacing main cleaning head
