A brush assembly comprising a cushion pad and a plurality of brushes secured to the cushion pad. The cushion pad has a 25% compressibility within the range of 6.9 kPa (1psi) to 2413 kPa (350 psi). At least one of the plurality of brushes comprises: a brush base, and bristles, the bristles comprising moldable polymeric material and abrasive particle additives.
技术功效语段：
The present invention provides a durable cleaning device for hard floors that is more efficient and consistent than existing brush assemblies. The brush assembly includes a cushion pad and a plurality of brushes secured to the cushion pad. The cushion pad has a compressibility within a certain range and includes abrasive particles to improve cleaning and polishing of floor surfaces. The brush assembly allows for individual replacement of brushes, reducing waste and improving economy. The cushion pad compensates for uneven surfaces and can easily remove and replace a single broken or worn brush without replacing other brushes. The present invention provides a better solution for cleaning, resurfacing, and finishing rough floor surfaces.
