ABSTRACT:
A vacuum cleaner has a cleaner body section having a first recess, and a second recess. The vacuum cleaner further has a first connector section, a second connector section, a suction pipe section and a brush section. First and second arc-shaped slots are provided in order for first and second protrusions of the first connector section to be slidably inserted in the slots and to be placed on the first recess. The second connector section is fixedly inserted in the second recess. The first connector section is connected to the second connector section. When the vacuum cleaner is used in the upright mode, the brush section is detachably connected to the first connector section and the suction pipe section is detachably connected to the second connector section, to thereby provide an air passageway from the brush section, the first connector section, the second connector section, and the suction pipe section, up to the cleaner body section. When the vacuum cleaner is used in the canister mode, the brush section is detachably connected to the suction pipe section directly to provide an air passageway from the brush section to the cleaner body section.
