  • Patent number: 11090794
    Abstract: A self-adjusting cable guide can be coupled to a nosepiece assembly having a contact end and can be movable between an extended guide position and a retracted guide position relative to the contact end of the nosepiece assembly. A contact trip arm can be adjacent the cable guide and can have a distal end positioned to contact a cable received within a guide recess of the cable guide. The contact trip arm can be movable between an extended arm position corresponding to an inactive state of the tool and a retracted arm position corresponding to an active state of the tool. In addition, the cable guide can have a non-aligned orientation, in which cooperating misalignment stop surfaces can engage each other to stop movement of the self-adjusting cable guide toward the retracted guide position and an aligned orientation in which movement into the retracted guide position is permitted.

  • Patent number: 10918248
    Abstract: A vacuum cleaner that can quickly be configured in various operating modes, including a standard-style upright vacuum, upright vacuum capable of cleaning under furniture, stick vacuum, handheld vacuum, and pod vacuum. An example embodiment is a surface cleaning apparatus that includes an elongated support member, a handle coupled to an upper end of the elongated support member, a vacuum module slidably and detachably coupled to the elongated support member, and a hose coupled to the vacuum module and expandable to accommodate lower and upper positions of the vacuum module along the elongated support member. The surface cleaning apparatus can further include a floor nozzle detachably coupled to a lower end of the elongated support member and the hose.
