  • the upright type vacuum cleaner 610 has a configuration in which the suction nozzle 613 is directly connected to the vacuum cleaner main body 611, and thus has the following advantages compared to the canister type vacuum cleaner. That is, the canister type vacuum cleaner is configured to be used with a hose or an extension pipe connected between the vacuum cleaner main body and the suction nozzle, but the upright type vacuum cleaner 610 includes the vacuum cleaner main body 610 and the suction nozzle. 613 is substantially integrated. Therefore, its mobility is better than that of a canister type vacuum cleaner. Moreover, since the upright type vacuum cleaner 610 can generally exhibit a strong dust collecting force because the suction nozzle 613 includes a rotating brush, it can be preferably used for carpet cleaning, for example.
  • the user may hold the upper handle 614 and move the suction nozzle 613 through the lower cleaner body 611.

Therefore, when the upright type vacuum cleaner 610 is used, a negative pressure for sucking the floor surface is always generated on the lower surface of the suction nozzle 613. This negative pressure can be a resistance when the suction nozzle 613 is moved. Furthermore, if the floor surface is a carpet, even if the lower surface of the suction nozzle 613 simply comes into contact with the carpet pile, it receives a certain amount of resistance. In addition to this, if the carpet pile is lifted up while the rotating brush rotates, the lower surface of the suction nozzle 613 will receive even more resistance.
