Problems solved by technology

Even when not in use when washing and not conducting air during washing operations, the dry sweep dust filter becomes saturated and clogged with damp and wet debris due to its close proximity to the debris hopper
Therefore, a saturated filter drier becomes ineffective when required as a drier dust filter

Abstract

An industrial floor scrubber includes a solution tank and delivery system for applying the solution to the floor, and one or more rotating brushes for removing dust and debris from the floor and respectively directing same to a squeegee and to a debris hopper. The trailing squeegee removes the remaining solution from the floor and, in combination with a vacuum system, directs the recovered solution to a cleaning solution recovery tank in the scrubbing mode of operation. In a sweeping mode of operation, the use of a dust filter is eliminated as the dust-laden air is directed past the debris hopper and onto the upraised squeegee which confines and directs the dust-laden air into a spray of fine water particles which adhere to and transport the dust-bearing water particles to the recovery tank via an applied vacuum. The heavy dust-bearing water particles drop into the recovery tank, while a demister removes the remaining water vapor with the dry air discharged to the atmosphere via a vacuum impeller.

Description

technical field [0001] The present invention relates generally to apparatus and methods for maintaining and conditioning generally planar surfaces, and in particular to washing and cleaning floor surfaces using a single apparatus that is easily transitionable between a wet washing / sweeping mode of operation and a dry sweeping operation without altering or replacing any components or systems. Background technique [0002] Industrial floor scrubbers typically include: a cleaning solution tank; a solution delivery system for applying cleaning solution to the floor in front of one or more rotating cylindrical or disc scrubbing brushes for cleaning the floor; tail for drying the floor; a vacuum system for recovering the cleaning solution; and a recovery tank for holding the recovered cleaning solution. In addition, floor scrubbers employing cylindrical scrub brushes often have a debris hopper located at the rear of the scrub brush to capture wet debris swept from the floor by ty...
