ABSTRACT:
The floor cleaning machine utilizes an integrated sound baffle to reduce the noise level of the machine during operation. The floor cleaning machine relies upon a vacuum motor to create a negative pressure in a recovery tank for operation of a vacuum squeegee. The integrated sound baffle is a hollow u-shaped body having an interior passageway through which the exhaust from the vacuum motor is directed. The noisy exhaust is required to turn four 90.degree. corners as it passes through the interior passageway of the baffle which reduces the noise level of the exhaust. The moist exhaust is also isolated from the brush motor and the vacuum motor while it passes through the hollow baffle. The baffle is an integrated component of the apparatus and is a load bearing member for the solution tank and the recovery tank. The baffle can be roto-molded using conventional techniques with a thermoplastic such as HDPE.
