Title: William George Plummer: Innovations in Autonomous Cleaning Systems
Introduction
William George Plummer is an inventor based in London, United Kingdom, whose work focuses on autonomous vacuum technology. He is associated with Matic Robots, Inc. His patent portfolio includes 2 patents addressing mopping and sweeping systems for autonomous vacuums.
Latest Patents
Plummer’s latest patents describe complementary approaches to improving the cleaning performance and operation of autonomous vacuums.
The **Autonomous vacuum mopping system** combines mopping and sweeping functions. A magnetic locking system holds the cleaning head in its mopping position, enabling the vacuum to move a mop roller back and forth to scrub stubborn stains. Snorkel ducts route liquid waste and water from the roller to a waste bag, keeping them separate from dry debris. The ducts kink shut during sweeping to prevent unnecessary suction. The system also uses cleaning routines to monitor and control roller saturation and drying, and to perform automatic mop cleaning.
The **Autonomous vacuum sweeping system** uses a brush roller to move dust and debris toward a collection duct. Guards and buffer zones help limit fibrous debris from wrapping around rotating parts, reducing friction. After the brush roller is unlocked from its position against the cleaning head, debris collected in the buffer zones can be suctioned into the debris compartment. A wedge seals the debris-ingestion cavity from the surrounding environment.
Career Highlights
Plummer’s disclosed inventions address practical challenges in robotic floor care, including stubborn stains, separation of wet and dry waste, brush maintenance, and debris collection. Together, the systems describe ways to coordinate mopping and sweeping functions while managing waste and reducing operational friction.
