Abstract
Abstract An upright-type vacuum cleaner in which a cyclone body is connected to and separated from a cleaner body without the use of a separate tool. The upright-type vacuum cleaner has a cleaner body having a suction brush formed at a lower part, and a vacuum-generating device built therein. A cyclone unit for separating dust from the air drawn through a suction passage is connected with the suction brush, and discharges the cleaned air through a discharging passage connected with the vacuum-generating device. A dust-container is removably connected with a lower part of the cyclone unit, for collecting the separated dust by the cyclone unit. The cyclone unit has a locking handle, and a handle connection portion for removably connecting with the locking handle, formed on a corresponding place on the cleaner body.
