  • Patent number: 11793375
    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.
