42-inch wide sweeping path 759936694882with 17 cu. ft. hamper. Higher tip velocity; brushes have more force to move object up off the ground and into the hamper. Consistent brush to ground contact prevents unit "skipping". By reducing tip lift (the distance the brushes actually lift off the surface between strokes), 6-brush design increases brush to ground contact. Six 11" diameter brushes. Exclusive self-storing feature provides compact storing in upright position.
