How do you assemble the vacuum?

1. Assembly of the floor brush and metal extension rod: When connecting, hold the floor brush, vertically insert the mounting hole under the metal extension rod into the floor brush connector, and align the conductive pins until you hear a "click" that means you have finished the assembly.
2. Assembly of the metal extension rod and vacuum body: Align the conductive pins of metal extension rod with the adaptor of nozzle, and push upward with force until you hear a locking sound of "click".
