Benefits of technology

[0012]The present disclosure has been developed in order to overcome the above drawbacks and other problems associated with the conventional arrangement. An aspect of the present disclosure is to provide an upright type vacuum cleaner capable of preventing a connecting portion between a body duct of a cleaner body and a brush duct of a suction nozzle from being blocked and minimizing drop of suction force and increase of noise.

Problems solved by technology

However, when the flexible hose is used as the duct connecting the suction nozzle and the cleaner body, the flexible hose may be clogged with the drawn-in contaminants.
Also, because the flexible hose has the inner surface formed in prominence and depression portion, a suction force may be decreased and noise may be increased compared of a hose having a smooth inner surface.
Furthermore, the flexible hose has less stiffness so that it may be easily contorted while cleaning.
