The TRUTH About Vacuums #4
Old-time vacuums could handle carpet powder much better than most new ones. When carpet powder gets in the pores of your filters or bag, it cuts off airflow, which makes the motor run hot as it tries to get air. Heat + plastic equals a melted vacuum, and/or a burned up motor. If the vacuum is bagless, the problem is much more pronounced, as you keep the same filters in for a long time, & changing them more frequently is cost-prohibitive.
