Patent number: 9861242Abstract: A vacuum cleaner is described that includes an elongated vacuum body, an optional battery-pack attached to the bottom end of the elongated vacuum body, and a removable backpack assembly with shoulder and waist straps attachable directly to the elongated vacuum body. The shape of the elongated vacuum body is such that the center of gravity of the body is shifted close to the body of the vacuum appliance user, allowing for greater freedom of movement during use. The vacuum appliance also includes exhaust air vents positioned to reduce the noise output of the vacuum appliance as perceived by the user during use.Type: GrantFiled: August 31, 2016Date of Patent: January 9, 2018Assignee: EMERSON ELECTRIC CO.Inventors: Mark Tomasiak, Douglas K. Ritterling, Shane Glasgow

Patent number: 9282861Abstract: Described is a vacuum cleaner, such as a wet/dry vacuum cleaner, having an improved vacuum hose storage assembly and dust pan assembly for use with a vacuum cleaner having a debris collection drum. The integrated pickup port in the dust pan can be formed by the shape of the product its used on or become a separate piece such as used in this design. The advantage of having the design integrated in the vacuum allows the user to pick up debris either collected by a broom or by other means into the collection chamber of the vacuum without having to remove the hose from the storage position and without having to hold the product while in use; freeing the users hands to control the broom or other device to direct additional debris to the vacuum for collection.Type: GrantFiled: May 13, 2013Date of Patent: March 15, 2016Assignee: EMERSON ELECTRIC CO.Inventors: Douglas Schultz, Douglas K. Ritterling, Shane Glasgow
