Your vacuum could be blowing dust back into your home every time you clean: the 5-minute reset most missYou push it across the rug, watch the little light glow, and figure the dust is going in. That’s what happens when an ordinary vacuum gets a little neglected, and nobody notices. As dust piles up, less air gets through, and the motor works harder to move less. When the intake gets choked and the airflow slows, the motor gets weaker and hotter. Instead of catching dust, the vacuum starts spraying a fine mist of it right back into the room.
