Abstract: A tool for a floor machine. The tool includes a base having a plurality of slots, and a cleaning element provided in each of the slots. The cleaning elements are oriented along a secant or chord of the base. The cleaning elements have abrasive portions with abrasive grit thereon, and may be non-planar at least at a portion of the abrasive portion.

Abstract: A floor treatment assembly may include drive block and a plurality of floor abrasion assemblies. The drive block includes a top side and a bottom side, the plurality of floor abrasion assemblies are coupled to the bottom side of the drive block. Each of the floor abrasion assemblies includes a nest movably coupled to the drive block, and an abrasion feature mounted to the nest such that the abrasion feature and the nest are operable to move relative to the drive block. In embodiments, each of floor abrasion assemblies includes a support plate mounted to the drive block, with the nest and the abrasion feature being movable relative to the support plate. The abrasion feature may be a grinding wheel or filament (or tufts of filament) supported by the nest.
