摘要： 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.
