    摘要： Embodiments include a surface maintenance machine, comprising a maintenance tool chamber comprising a first side, a second side, a third side and a fourth side. A rotary broom is housed in the maintenance tool chamber and substantially enclosed by the first, second, third and fourth sides thereof. The rotary broom sweeps particulate from the surface. A vacuum system generates vacuum for drawing particulate swept by the rotary broom. The vacuum system is positioned proximal to the first side. A skirt assembly extends substantially around the second, third and fourth sides of the maintenance tool chamber. The skirt assembly has a vacuum passage defined therein and in fluid communication with the vacuum system to direct air flow into the vacuum passage, thereby drawing particulate into the vacuum passage and preventing particulate accumulation at portions of the second, third and fourth sides that are distal to the vacuum system.

    摘要： A cleaning head assembly for a surface maintenance machine comprising a cleaning tool having a tool adapter, a driver adapted to provide a generally rotational motion to the cleaning tool to clean the floor surface, the driver being releasably connected to the tool adapter of the cleaning tool by a hub, and an aligning receptacle coupled to the tool adapter of the cleaning tool and positioned between the hub and the tool adapter, the aligning receptacle having an receptacle opening for receiving the hub, wherein the aligning receptacle is adapted to guide and matingly seat the hub into the receptacle opening and thereby engage the cleaning tool to the driver such that the cleaning tool and the driver are rotationally aligned and a rotational motion of the driver is transferred to the cleaning tool by the hub.

    摘要： Certain embodiments include a fluid recovery system. The fluid recovery system includes a vacuum system that applies a suction force on fluids on the floor surface to draw fluids to a fluid recovery tank. A reservoir is operably coupled to a recovery hose. The reservoir includes an inlet passage, an outlet passage leading to the recovery hose, and a fluid trap portion positioned between the inlet and outlet passages. The reservoir permits passage therethrough of fluids suctioned by the vacuum system from the floor to the recovery hose, and traps a backflow of fluids from the recovery hose in the fluid trap portion when the vacuum system stops suctioning fluids from the floor to the recovery hose. The reservoir is shaped to be generally self-cleaning and clears most fluids trapped in the fluid trap portion when the vacuum system starts suctioning fluids from the floor to the recovery hose.

    摘要： An electrolysis cell (10) is provided, which includes an inlet (12, 63, 65), an outlet (36, 63, 65), and coaxial, cylindrical inner and outer electrodes (20, 22). A cylindrical ion- selective membrane (18) is located between the inner and outer electrodes (20, 22) and forms respective first and second electrolysis reaction chambers (14, 16) on opposing sides of the membrane (18). Fluid flow paths along the first and second chambers (14, 16) join together as a combined inlet flow path (70) through the inlet (12, 63, 65) and a combined outlet flow path (72) through the outlet (36, 63, 65).
