Textile covering i.e. carpet, cleaning device for motor vehicle e.g. car, has extrados bulged in brush driving direction and including cleaning surface to tap and sweep textile covering, when brush is rotatably driven by driving units

摘要

The device (1) has driving units rotatably driving a brush (10) around a rotation axis (X-X). The brush has clipped groups (20) of brushing filaments (22), which are distributed in spaced manner along a direction peripheral to the axis. The filaments of each group have a curved longitudinal section to collectively define an extrados bulged in a brush driving direction (R). The extrados has a cleaning surface to tap and sweep a textile covering, when the brush is driven by the units. The filaments are made of abrasive particles e.g. aluminum oxide or silicon carbide particles, loaded nylon. An independent claim is also included for a method for fabricating a brush for a cleaning device.
