There are some things, though, that just shouldn't be vacuumed up--for your health and that of your machine.
Problem: Carpet powder is so fine it escapes bags and filters and gets into the bearings, motors, and the fans of your machine. This, in addition to damaging critical inner-workings, sends the dust into the air and your lungs. Carpet powder is also known to clog the pores in vacuum bags and filters. This means your vacuum can not breath and could overheat--possibly to the point of burning out the motor.
Solution: If you want to improve the smell of your vacuum, spray a favorite scent onto a tissue and vacuum it into the machine. (Do NOT spray anything directly onto a bag or filter, it will cause damage)
