  • Publication number: 20070180645
    Abstract: A mobile hard surface cleaner includes a motorized scrub head, a fluid recovery device, a primary cleaning liquid component container, a cleaning agent container, a flow control device and a fluid flow path. The flow control device is configured to supply a flow of cleaning agent from the cleaning agent container at a predetermined volume flow rate of greater than 0 cubic centimeters per minute and less than 10 cubic centimeters per minute to a flow of primary cleaning liquid component from the primary cleaning liquid component container. The fluid flow path is configured to receive a flow of cleaning liquid, which comprises the cleaning agent and the primary cleaning liquid component.

  • Publication number: 20060150352
    Abstract: A cleaning tool generally comprises a hub having a longitudinal axis and a plurality of cleaning members. The cleaning members, formed of a fibrous material, are connected to the hub. In accordance with one embodiment, the cleaning members are distributed along the longitudinal axis. Also disclosed is a floor cleaning machine that includes a mobile body, the cleaning tool and a motor. The mobile body supports the cleaning tool and the motor and is configured to travel over a surface. The motor is configured to drive a rotation of the cleaning hub about the longitudinal axis.

  • Publication number: 20060137127
    Abstract: A cleaning system includes a supply of purified water, a supply of cleaning agent, a mixing junction, and a distributor. The mixing junction is configured to combine a flow of the purified water and a flow of the cleaning agent and output a flow of cleaning liquid comprising the flows of the purified water and the cleaning agent. The distributor includes an output through which the cleaning liquid can be discharged. In a method of cleaning a surface, flows of purified water and cleaning agent are provided. The flow of purified water and the flow of cleaning agent are mixed to form a flow of cleaning liquid. The flow of cleaning liquid is then discharged to the surface.

  • Publication number: 20060099351
    Abstract: The invention is directed to an aggregate floor coating and method/system for applying the same. In one embodiment, a base layer of epoxy or equivalent material may be applied to a prepared floor surface. Prior to curing of the base layer, a quantity of aggregate flooring material, e.g., quartz particles, may be broadcast over the exposed surface of the base layer. Upon curing of the base layer, an ultraviolet (UV)-curable topcoat layer may be applied. Exposure of the UV-curable topcoat layer to one or more specific wavelengths of UV energy results in fast curing of the topcoat layer, permitting quick resumption of floor traffic. Coatings of the present invention provide numerous advantages, such as allowing application of aggregate floor coatings in well-lit, e.g., sun-exposed areas.

  • Publication number: 20050217062
    Abstract: A surface cleaner includes a liquid dispensing system comprising a fluid flow path configured to receive a flow of liquid, a pump, an air purging component, and a valve actuator. The pump is in line with the fluid flow path and is configured to drive the flow of liquid through the fluid flow path. The air purging component includes an inlet in line with the fluid flow path, an outlet, an airflow path connecting the inlet and the outlet, and a valve in line with the airflow path. The valve includes an open position in which the airflow path is open between the inlet and the outlet and a closed position in which the airflow path is closed between the inlet and the outlet. The valve actuator is connected to the valve and is configured to bias the valve in the open position when air is detected in the fluid flow path.
