Abstract: A floor maintenance machine includes a clean fluid tank with a discharge funnel running therethrough that forms part of an exhaust pathway for a vacuum source. The vacuum source discharges an exhaust during operation of the machine from the exhaust outlet into the discharge funnel. The exhaust may be gaseous and/or include a liquid component in the case of a machine malfunction if liquid from a recovery chamber is non-ideally drawn into the vacuum source in the case a fail-safe does not work. The discharge funnel can provide a way for the liquid to exit the interior of the machine in such case.

Abstract: A floor maintenance machine includes a chassis, a floor-cleaning implement adapted for engagement with the floor, and a service cabinet. The floor-cleaning implement is supported by the chassis. The service cabinet is coupled to the chassis and defines a cavity. The cavity receives a plurality of fluid access points collectively therein.

Abstract: A fueling mat includes a main body configured as a sheet. The main body includes an opening defined in the main body and a plurality of tabs. The opening defines an outer perimeter and the tabs extend inwardly from the outer perimeter. The tabs are configured to flex out of the opening. With this structure, the tabs can protect the region of a fuel port from damage, whether or paint or structural, during fueling and further can help cover the opened fuel port, at least fractionally, before a fuel nozzle is inserted.

Abstract: A floor maintenance machine has an adjustable deck assembly. The floor maintenance machine includes a deck supporting a floor cleaning implement. A lifting arm extends away from a frame of the floor maintenance machine and is rotatably coupled to the deck. The lifting arm is rotatably actuatable to adjust a position of the deck relative to the frame. A support member is rotatably coupled to the frame and movably coupled to the deck. A stop member is supported by the deck and extends toward the lifting arm for selective engagement therewith. When the lifting arm is rotated relative to the frame to lift the deck, the stop member is driven into the lifting arm to limit relative rotation between the lifting arm and the deck beyond a set angle.

Abstract: A fluid collection system for a floor maintenance machine provides improved collection of fluid, foam, and debris prior to the vacuum source. The fluid collection system includes a recovery chamber defining a volume, a hollow structure (such as a modified skirt) having an internal chamber, and a vacuum source in fluid communication with the volume of the recovery chamber via the internal chamber and a vacuum line. The vacuum source draws a vacuum in the volume of the recovery chamber by drawing a gas from the volume of the recovery chamber through the internal chamber of the hollow structure and through the vacuum line.

Abstract: A machine with a cleaning system and a tugging system. The cleaning system can include a floor cleaning feature configured to dispense a cleaning solution onto a floor surface, agitate the cleaning solution, and remove the cleaning solution from the floor surface. The cleaning system can include an onboard cleaning solution tank, an onboard recovery tank, and an onboard vacuum. The tugging system can include a hitch coupled to a front end of the machine and can be configured to tow an airplane.

Abstract: A floor maintenance machine includes a clean water tank and a brush deck. A first and second fluid supply system place the clean water tank in fluid communication with outlet(s) at the brush deck. The first fluid supply system includes a first fluid supply line adapted to receive a soap or detergent therein supplied from a soap or detergent well. The second fluid supply system includes an ozone generator and a second fluid supply line adapted to receive injected ozone therein with the ozone being generated from the ozone generator.

Abstract: A floor cleaning implement, such as a disc brush, for use in a floor maintenance machine includes a core providing a female portion of a mating interface. The female portion has a central recess with a plurality of pockets extending radially outward from the central recess. Each of the plurality of pockets has a head section that is radially distal from the central recess and has a neck section that is radially intermediate the respective head section and the central recess. Each head section is wider in an angular direction than the corresponding neck section.

Abstract: A cylindrical brush with an improved core and a mating driving hub have axially inclined splines that engage one another to form an improved cylindrical brush assembly for a floor maintenance machine.
