Abstract
Abstract A vacuum cleaner handle comprising a connection member connected to a handle tube and a handle member by which the vacuum cleaner handle is held during use and may be moved along with only little effort. In the working position of the vacuum cleaner, this handle member includes a handle portion positioned at least partly disposed over the axis of a central handle tube and at an acute angle thereto. A cord drum is attached to the vacuum cleaner handle. A cord of the vacuum cleaner may be wound up in the cord drum simply and neatly without the cord drum placed under the vacuum cleaner handle interfering with the use of the vacuum cleaner.
