ABSTRACT:
An automatic floor scrubber (10) is disclosed having its frame divided into a truck (12) and an upper assembly (14) isolated from each other by a multiplicity of elastomeric isolator mounts (106) arranged in a nonlinear fashion. The wheels (18, 20), the drive motor (22), the squeegee system (26), and the brush scrub system (28) are mounted to the subframe (16) of the truck (12). The control handle (46), solution tanks (48, 50), and batteries (74) are mounted to the chassis (44) of the upper assembly (14). The mounts (106) include integral first and second portions (108, 110), with the first portion (108) sandwiched between the subframe (16) and the chassis (44) and the second portion (110) insertable into a mount aperture (118) and axially compressed into a mushroom shape by bolts (122) to capture the mount aperture (118). An acoustical tunnel (84) extends longitudinally in the chassis ( 44) intermediate the batteries (74) and defines a closed volume lined with foam sheets (88). The outlet hose (104) of the vacuum system (52) extends through the open end of the tunnel (84) and exhausts the air therein, with the air escaping from the closed volume flowing around the outlet hose (104) and through the open end of the tunnel (84).
