Abstract: A street sweeper with vacuumized dust control where a rotary broom chamber surrounds a rotary broom. The rotary broom chamber connects by a conveyor housing containing a conveyor mechanism to a hopper having a powered fan and a filter. A vacuum or low pressure is created within the hopper which communicates through the conveyor housing to the rotary broom chamber which creates an airflow therebetween which carries dust or other light debris to a filter which filters out the dust particles or other light debris. The conveyor housing and other components are positionable to accommodate various modes of operation.

Abstract: A battery powered floor maintenance machine (100) is alienable with a battery docking station (200) that can slidably receive a spent battery assembly (108) from the floor maintenance machine (100). The floor maintenance machine (100) includes locking and aligning mechanisms (120) to safely attach the machine (100) to the docking station (200). Once attached, the battery assembly (108) is slid onto the docking station (200) for recharge. The floor machine (100) can be removed from the docking station (200) and attached to a second charging station (200) with a fully charged battery assembly (108) thereon. The battery assembly (108) can be slid from the second charging station (200) to the floor maintenance machine (100), allowing the machine (100) to be returned to service.

Abstract: A control system for controlling the work output delivered to a floor surface by a work tool (18) associated with a floor maintenance machine (10), such as a burnisher, is provided. In one embodiment, a voltage regulator regulates the voltage provided to the motor assembly (16) that drives the work tool. A current sensor (50) monitors the motor current drawn by the motor assembly and provides a signal representative thereof to a controller (60). The controller also receives as an input a work selector signal representative of a desired level of work output. Based on the work selector signal and the sensed motor current, the controller provides a control signal to an actuator (20). In response to the control signal, the actuator raises or lowers the work tool (18) relative to the floor (24) as need to control the work output delivered to the floor. In another embodiment, the voltage regulator is omitted, and the controller is configured to generate the control signal based on the product of the motor current and the voltage provided to the motor assembly.

Abstract: A torque transmitting ball joint can include a spherical ball, a stem extending from the spherical ball, one or more pins coupled to the spherical ball, and a socket. The socket can define an opening sized to contain the spherical ball within the socket and one or more slots sized to accommodate a pin of the one or more pins. The one or more pins can be contained by the one or more slots and can translate within the slot as the spherical ball rotates relative to the socket about a pivot center. At least one of the one or more pins can abut a sidewall of its slot and transmit torque from the stem to the socket via the spherical ball when the stem and spherical ball rotates relative to the socket.

Abstract: A handheld suction device (10) may provide an ergonomic and convenient device for cleaning a variety of floor surface soils, including liquid soils. In different configurations, the device may provide a variety of different features to efficiently collect and hold liquid removed from the floor surface and/or prevent vacuum motor flooding if the operator over rotates the device when filled with liquid. In some applications, the handheld suction device provides an interchangeable system that allows the operator to switch between different suction attachments designed for picking up liquid soil and solid soil.

Abstract: Systems and methods for detecting a site maintenance operation done by a maintenance device are described. At least one motion sensor and at least one localization system can each be operatively coupled to the maintenance device to detect one or more motion parameters of the maintenance device via the motion sensor and the localization system. The maintenance device can be localized (e.g., its position located) on the indoor map. A movement of the maintenance device can be characterized and/or tracked on the indoor map. A motion map can be displayed to illustrate (e.g., visually represent) the characterized movement. An offsite computer can be used to determine whether the site maintenance operation has commenced at the indoor location, measure one or more maintenance parameters of the site maintenance operation and/or compare the one or more maintenance parameters to predetermined benchmark parameters to determine whether the site maintenance operation has been completed.

Abstract: Embodiments include a waste recovery system for a floor surface maintenance machine. The waste recovery system comprises a squeegee assembly having a squeegee frame, a squeegee retainer extending below the squeegee frame and a reservoir integrally defined in the squeegee retainer. The reservoir can have an inlet passage proximal to the floor surface, an outlet passage fluidly coupled to the fluid suction path and leading to the waste recovery tank, and a fluid trap portion positioned between the inlet and outlet passages. The fluid trap portion can retain backflow fluids in the fluid suction path. The reservoir is positioned at a clearance distance from the floor surface in a direction normal to the floor surface such that the reservoir forms the lowest portion of the waste recovery system in the direction normal to the floor surface.
