Abstract
A floor nozzle of a vacuum cleaner is provided with an upper nozzle housing hingedly connected to an intake joint of the cleaner and a lower nozzle housing securely connected to the upper nozzle housing through a bumper, with an intake opening being formed on a lower side of the lower nozzle housing. A first air passage communicating between the intake opening and the intake joint is formed in the upper and lower nozzle housings. A dust collector is accommodated in the nozzle housings, and defines in it a second air passage communicating the first air passage. A thread catcher is so accommodated in the dust collector as to be rotatable in response to forward and rearward movement of the floor nozzle. The thread catcher is capable of catching waste thread on a surface to be cleaned when it rotates upon forward movement of the floor nozzle. A scraper is accommodated in the dust collector for removing the waste thread caught by the thread catcher when the thread catcher rotates upon rearward movement of the floor nozzle. A covering member is hingedly connected to the dust collector for opening or closing the second air passage.
