Brush on/off Brush on/off An on/off switch for the rotating brush lets you stop the brush from rotating when using tools or cleaning bare floors. That helps eliminate scattered dirt on bare floors and reduces the risk of injury if the vacuum tips over in use. It also reduces the risk of damaging a carpet or floor if the vacuum sits in place on the low-height setting.
