  • Patent number: 10881260
    Abstract: 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.

  • Patent number: 10595697
    Abstract: 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.

  • Patent number: 10470637
    Abstract: An auxiliary waste removal system for a surface maintenance machine, having a vacuum wand for removing waste from the floor surface, a reusable bagless waste collection container removably coupled to the vacuum wand, and a vacuum source fluidly coupled to the bagless waste collection container, the vacuum source generating a vacuum flow from an inlet of the vacuum wand to a vacuum outlet, the vacuum outlet being positioned downstream of the bagless waste collection container and the vacuum source such that the waste suctioned from the floor surface by the vacuum wand travels along the vacuum flow path and is directly received in the bagless waste collection container.
