I use a shop vac for the dust collector in my cabinets. 
the dust can and will cause an early failure to the motor.
To help stop this,  fill the bottom of the canister with
2" to 4" of water and make sure the diverter on the input
is pointing down.  The water will trap most of the dust so
doesn't make it to the motor.

Also using an additional canister between the shop vac and
the cabinet will help catch the dust.
