摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
