  • Squeegee assembly and method of using same
    Patent number: 8051530
    Abstract: A squeegee blade assembly and method of use for a floor surface maintenance machine. A blade/guide subassembly is inserted into a channel of a scrub head prior to operation. During operation, the subassembly is retained with the channel via friction and/or protruding structures. During a blade exchange procedure, the subassembly is retracted from the channel prior to separation of the blade from the guide. Interaction with a protruding structure within the channel signals to an operator that the subassembly has been properly positioned.
