Abstract
A cleaning machine for cleaning floor surfaces is disclosed characterized by a squeegee blade assembly that utilizes a number of connectors for dual functions. The squeegee blade assembly includes a holding subassembly for maintaining the squeegee blades in place. A plurality of connectors are used to connect the squeegee blades to the squeegee holding subassembly. A first set of these connectors also connects the squeegee holding subassembly to a squeegee mounting assembly, which is attached to the body of the cleaning machine. A second set of these connectors is also used to connect rollers to the holding subassembly. A third set of these connectors also attaches a caster assembly to the holding subassembly. Each squeegee blade is an integral, one-piece member but with an upper section having a greater hardness than the lower section.
