Dead easy.
Pull the hose back at the bottom where it connects to the machine. Behind the hose there is a plastic tag that you must pull back. This releases a catch and allows the hose and connector to be pullled upwards and out of the machine. It may need a little force but it will definitely come out.
As to the handle - I suspect that the handle comes as a complete assembly with the metal wand.
