By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-According to news reporting originatin g from Washington, D.C., by NewsRx journalists, a patent application by the inve ntors Chandrashekaraiah, Karthik (San Francisco, CA, US); Gervais, Tristan Pierr e (Sunnyvale, CA, US); Jain, Vishal (Santa Clara, CA, US); Kumar, Anshuman (San Francisco, CA, US); Liao, Kaiwen (Sunnyvale, CA, US); Madonia, Nathan Elio (Moun tain View, CA, US); Plummer, William George (London, GB), filed on August 10, 20 23, was made available online on February 15, 2024. No assignee for this patent application has been made. Reporters obtained the following quote from the background information supplied by the inventors: "Conventional vacuum systems can use brush rollers to assist i n moving dust and debris to be suctioned by the vacuum. However, brush rollers o f conventional vacuum systems have various issues such as cleaning efficiency, n oise, and power consumption. Hairs can wrap and accumulate around the outside of the brush roller, which worsens cleaning performance. Hairs can also jam or uns eat rotating brush rollers, which completely stops cleaning performance until th e brush roller is unjammed or reseated. Flaps of brush rollers can be noisy as t hey successively strike the ground during cleaning. Conventional vacuum systems may also expend additional power to rotate a brush roller against additional fri ction caused by hairs that accumulate around the brush roller and may wrap aroun d a rotating portion of the brush roller (e.g., a drive pinion). Cleaning fibrou s debris from conventional vacuum systems can be inconvenient for the user and i s often challenging because removal or insertion of a vacuum's brush roller requ ires complex procedures, additional tools, or undue force, which may damage the vacuum or brush roller. Furthermore, large debris may be unable to be ingested i nto conventional vacuum systems due to insufficient room or because the large de bris enters at edges of a brush roller.
