ROTARY SURFACE CLEANING TOOL

摘要

599883 A rotary surface cleaning machine, comprising: a rotary surface cleaning tool coupled for high speed rotary motion and further comprising a substantially circular operational surface; a plurality of individual arrays of cleaning solution delivery spray nozzles being angularly distributed across the operational surface of the rotary surface cleaning tool and being coupled in fluid communication with corresponding liquid cleaning fluid distribution channels of a cleaning fluid distribution manifold portion of the rotary surface cleaning tool, wherein each of the plurality of individual arrays of cleaning solution delivery spray nozzles further comprises at least one or more individual delivery spray nozzles that are radially oriented across a maximum annular portion of the substantially circular operational surface of the rotary surface cleaning tool between an inner radial limit and an outer radial limit; a plurality of suction extraction shoes being angularly distributed across the operational surface of the rotary surface cleaning tool and being projected therefrom alternately between the arrays of cleaning solution delivery spray nozzles, and each of the suction extraction shoes further comprising a fluid extraction passage communicating with a vacuum manifold; and a vacuum plenum communicating with the vacuum manifold of the rotary surface cleaning tool, the vacuum plenum forming a cavity having an opening thereinto and further comprising a removable vacuum inlet cap assembly, comprising: an inlet cap sized for being releasably sealed with the opening into the cavity of the vacuum plenum, and a cleaning solution delivery tube sealed to the inlet cap and sized for being releasably sealed in communication with the plurality of suction extraction shoes.
