A floor scrubber (10) is disclosed including a drive lug (62) for removably connecting a scrubbing member (64) to a drive (60) and having a trough for receipt and catching of solution for passage to the surface. The mount (58) for the drive (60) is biased by a spring (67) to pivot relative to a linkage plate (46) in turn pivotably mounted to the chassis (12) at an acute angle to the forward movement direction. The vacuum assembly (92) is sandwiched in a socket (100) formed in the bottom wall of a recovery tank (90) by a mount (106) to deaden the sound generated thereby and to allow air communication is inside of the socket (100) but generally preventing entry of solution therein. The squeegee assembly (152) is biased by a gas spring (150) to engage the surface at a constant force independent of the pivotal position of the squeegee mount (148). The batteries (68, 70) can be easily electrically connected and disconnected to each other in series and to the scrubber (10) by polarity type connectors (80, 82, 84, 86) for ease of removal, replacement, and interchange of the batteries (68, 70) in the scrubber (10) without requiring the use of tools. The bumper wheels (30) are secured to a first plate (32) of a pocket (28) by a pin connector (36) passing therethrough and through the legs of a U-shaped bracket (42) having a central portion flushly abutting with a second plate (38) of the pocket (28) for transferring forces thereto.

1. A mechanism for a surface cleaning machine comprising, in combination: a bracket for mounting to the surface cleaning machine; a mount pivotably mounted to the bracket about a mount axis generally parallel to the surface; means secured to the mount for picking up solution from the surface; a gas spring having a first end pivotably mounted about a first axis relative to the bracket and a second end pivotably mounted about a second axis relative to the mount, with the first and second axes being parallel to and spaced from the mount axis to thereby engage the picking up means with the surface at a force which is constant independent of the pivotal position of the mount about the mount axis.
