Abstract: Disclosed are a conversion member and an electric cleaner. The conversion member according to embodiments disclosed herein may be detachably coupled to a handle included in a main body and a pipe. Then, the main body may be connected to an intake port located at the lowest position, and the pipe may be connected to an extension handle, allowing the main body to be located at a lower position facing the intake port. Thus, the electric cleaner may have a low center of gravity. Further, when the conversion member is detached, the pipe may be located between the main body and the intake port to be connected to the main body and the intake port, respectively. Accordingly, the main body may be located at an upper position directed away from the intake port, allowing the electric cleaner to have a high center of gravity.

Abstract: A dust cleaner includes a primary cyclone part formed by an outer case and an inner case; and a secondary cyclone part including a set of cyclones. The secondary cyclone part includes a casing member mounted on the inner case and configured to form casings of the cyclones arranged around a hollow part; and vortex finders provided inside the casings and including guide vanes extending in a spiral direction and forming a revolving flow at outer circumferential surfaces. The casing member forms inlet flow paths of the cyclones, and each of the inlet flow paths is formed in a direction inclined with respect to a direction toward a center of each of the vortex finders to enable air to flow in a direction eccentric from the center of each of the vortex finders.
