  • Patent number: 9375124
    Abstract: A scrub deck assembly (59) comprises a scrub deck frame (76) and a pivot arm (70) having a first end (72) and a second end (74). The pivot arm is rotatably coupled to the scrub deck frame at the first end, and a scrub brush (56A) is operably coupled to the pivot arm at the second end. The scrub deck assembly further comprises a retraction mechanism (80) configured to allow movement of the pivot arm, relative to the scrub deck frame, about the first end. A release mechanism (92) is operably coupled to the retraction mechanism, and is configured to disengage the operation of the retraction mechanism.

  • Patent number: 9341209
    Abstract: A retainer clip for a squeegee assembly comprises top and bottom clip members each having an interior surface and an exterior surface. The interior surface of the top clip member includes a first channel portion adjacent to a first end and a first interlocking feature adjacent to a second end. The interior surface of the bottom clip member includes a second channel portion adjacent to a first end and a second interlocking feature adjacent to a second end. Mating the first interlocking feature with the second interlocking feature positions the first channel portion adjacent to the second channel portion to form a pin receiving channel.
