A floor cleaning machine having a body in which the body cover assembly is hollow and serves as the recovery solution reservoir; while the lower body assembly, which is also hollow, serves as the cleaning solution tank or reservoir. In addition, the lower body has a recessed area proportioned to receive and secure the batteries required for driving the motors involved in the floor cleaning machine. A trans-axle drive supports the lower body and has a drive wheel at each end powered by a motor differential engaging the axles coupled to the wheels. Together the body and trans-axle drive comprise a modular power unit. Mounting means are provided on the forward portion of the lower body of the power unit for lift arms to be secured to various power floor scrubbers for use on hard floors or a carpet extractor for cleaning carpeted floors. The linkage for the floor scrubber mode and carpet cleaning mode is the same. Such linkage also uses a maximum number of resiliently mounted bushings which, along with the monocoque body and retained fluid movement, cushion against damage by impact under power.

Floor cleaning machine and method

Disclosed is a wet/dry carpet cleaner having a large tank assembly for fluids. A bladder containing fresh or cleaning water is positioned in the large tank. Nozzles for dispensing the cleaning water to a brush, a vacuum nozzle for vacuuming and returning soiled fluid to the recovery tank portion of the tank assembly is also provided. The present invention includes the method of securing a brush head assembly pivotably to the chassis assembly and includes the driving motor, rotating brush, and spray mechanism. The pivotal securement results in the weight of the brush head assembly applying a constant force on the brush throughout the entire cleaning cycle, independent of the amount of fluid contained in the recovery tank or the bladder. Also, the method is addressed to configuring and proportioning the bladder to insure a relatively constant load on the nozzle. By balancing the nozzle loading and, therefore, the downward pressure per square inch on the nozzle throughout the cycle compensation results for fluid loss or fluid re-distribution. With the brush loading remaining constant throughout the cycle, consistency is maintained during the entire period while the carpet is being cleaned.

Vacuum cleaner method

Disclosed is a wet/dry carpet cleaner having a large tank assembly for fluids. A bladder containing fresh or cleaning water is positioned in the large tank for dispensing the cleaning water to a brush. A vacuum nozzle for vacuuming and returning soiled fluid to the recovery tank portion of the tank assembly is also provided. The present invention stems from the development of a brush head assembly which is pivotably secured to the chassis assembly and includes the driving motor, rotating brush, and spray mechanism. The pivotal securement results in the weight of the brush head assembly applying a constant force on the brush throughout the entire cleaning cycle, independent of the amount of fluid contained in the recovery tank or the bladder. Secondarily, the present invention is addressed to configurating and proportioning the bladder to insure a relatively constant load on the nozzle. By balancing the nozzle loading and, therefore, the downward pressure per square inch on the nozzle throughout the cycle to compensate for fluid loss or fluid re-distribution; with the brush loading remaining constant throughout the cycle, consistency is maintained during the entire period while the carpet is being cleaned.
