Patent attributes
A vacuum cleaner includes a first tube and a second tube positioned within the first tube, where a first end of the first tube is connected to an outlet of the backbone and a first end of the second tube connected to an inlet of the backbone. A handle is on the first end of the first tube. When the backbone is in a retracted position the first end of the first tube surrounds the second end of the second tube, the second end of the second tube obstructs the outlet of the backbone, and the second end of the first tube surrounds the first end of the second tube. When the backbone is in an extended position the second end of the first tube aligns with the second end of the second tube, leaving the outlet of the backbone unobstructed to a dustcup. A floor nozzle is connected to the inlet of the backbone and includes a nozzle motor configured to operate a brush roll axle and a casing that provides an airpath to the inlet of the backbone.
