  • Publication number: 20200102765
    Abstract: An attachment for a pool vacuum includes a housing and a brushroll at least partially extending from the housing. The brushroll has a plurality of bristles configured to rotate about a first axis. The attachment further comprises a paddle wheel disposed in the housing. The paddle wheel is configured to rotate about a second axis that is parallel to the first axis. The attachment further comprises a torque transmission member coupling the brushroll and the paddle wheel. In response to rotation of the paddle wheel about the second axis, the torque transmission member is configured to rotate the brushroll about the first axis.

  • Patent number: 9861242
    Abstract: 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.

  • Patent number: 9282861
    Abstract: 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.

  • Patent number: 8631539
    Abstract: A vacuum extension wand accessory storage assembly for use with a wet/dry vacuum that improves user access to the wands while simultaneously preventing accidental loss or dislodgement of the wands when the vacuum is not in use. The wand storage design includes the combination of a channeled, shaped surface formed in the bottom of the vacuum collection drum and an accessory attachment system on the bottom of the vacuum appliance having both front and rear securement assemblies which in combination secure the extension wands in place below the collection drum of the vacuum appliance in the event of vacuum transportation, lifting, or storage.
