Publication number: 20180325342Abstract: A cleaning device may include a solution tank configured to store cleaning solution. The device delivers the cleaning solution from a pump discharge of the cleaning device to a flow meter. The device initiates a priming mode by opening a first valve associated with a bypass line of the device, closing a second valve associated with a cleaning head of the cleaning device, and delivering the cleaning solution from a discharge of the flow meter to the inlet of the solution tank through the bypass line. When the device is primed, it initiates cleaning by closing the first valve associated with the bypass line, opening the second valve associated with the cleaning head, and delivering the cleaning solution to the cleaning head.Type: ApplicationFiled: July 24, 2018Publication date: November 15, 2018Inventors: Stephen J.

Patent number: 9609991Abstract: A method of cleaning an area using an automatic cleaning device may include receiving, from a video camera, information associated with an edge located on a surface, determining, by an automatic cleaning device, a position of the automatic cleaning device on the surface relative to the edge and using the received information to move the automatic cleaning device from the determined position along a path so that the automatic cleaning device cleans the surface along the path. The path may be substantially parallel to the edge, and the edge may be located a distance from a reference point on the automatic cleaning device during movement of the automatic cleaning device.Type: GrantFiled: February 10, 2014Date of Patent: April 4, 2017Assignee: Diversey, Inc.Inventors: Henry L.

Publication number: 20160360940Abstract: A method of causing a mobile robotic device, such as an automated cleaning device, to navigate an area includes using a video camera to collect visual information associated with an area in which a mobile robotic device is located. A system receives information from the video camera, wherein the information comprises a value associated with a detected color in the area. The system compares the value associated with the detected color to a value of a requested color, and the system determines whether the value associated with the detected color is within a tolerance range of the value of the requested color. If the value associated with the detected color is within a tolerance range of the value of the requested color, the system accepts the color. The system uses the received information to adjust a position of the mobile robotic device in the area.Type: ApplicationFiled: August 11, 2016Publication date: December 15, 2016Inventors: Henry L.

Patent number: 9028617Abstract: A cleaning device may include a solution tank configured to store cleaning solution. The solution tank may include an inlet and an outlet. The cleaning device may include at least one discharge line filter in fluid communication with the solution tank and a pump having a pump intake and a pump discharge. The pump may be configured to direct cleaning solution from the solution tank outlet through the at least one discharge line filter. The cleaning device may include a cleaning head in fluid communication with the pump discharge and a bypass line in fluid communication with the pump discharge and the inlet. The bypass line may be configured to divert cleaning solution received from the pump discharge away from the cleaning head and toward the solution tank.Type: GrantFiled: April 12, 2011Date of Patent: May 12, 2015Assignee: Diversey, Inc.Inventors: Stephen J.

Patent number: 8958937Abstract: A floor cleaning machine includes a set of obstacle sensors that detect when the machine is approaching an obstacle. If the obstacle is less than a threshold distance away from the machine, the machine may output an alert and override the operator's command with a command to reduce the speed of the machine. If the obstacle is less than a minimum threshold distance away from the machine, the machine may come to a complete stop to prevent the collision.Type: GrantFiled: March 12, 2013Date of Patent: February 17, 2015Assignee: Intellibot Robotics LLCInventors: Henry L. Hillman, Jr., Erick Frack, Daniel M. Daly, David M. Knuth, Jr.

Publication number: 20100114372Abstract: A method of cleaning a surface using an automatic cleaning device may include learning, by an automatic cleaning device, one or more cleaning methods. Each cleaning method may be associated with a code corresponding to a radio frequency identification tag positioned in a vicinity of a surface to be cleaned. The method may also include receiving, by the automatic cleaning device, a target code from a target radio frequency identification tag positioned in a vicinity of a target surface to be cleaned, determining the cleaning method associated with the target code and applying the associated cleaning method to the target surface when the target radio frequency identification tag is detected.Type: ApplicationFiled: October 30, 2008Publication date: May 6, 2010Applicant: INTELLIBOT ROBOTICS LLCInventors: David M.
