摘要
A roller brush (310, 310a, 310b) for a cleaning appliance (100) that includes a brush core (314) defining a longitudinal axis of rotation (XA, XB) and three or more dual rows (325) of bristles (318, 320, 330) disposed on and equidistantly spaced along a circumference the brush core. Each dual row of bristles includes a first bristle row (325a) of a first bristle composition and having a first height (LB, LB1) and a second bristle row (325b) of a second bristle composition stiffer than the first bristle composition and having a second height (LB, LB2). The second bristle row is circumferentially spaced from the first bristle row by a gap (DC) less than or equal to 10% of the first height. Also, the first height is less than or equal to 90% of the second height.
