you have to undo the screws at the bottom - all of them
then take the head bit off - ie the bit the revolving brush is on
then once you get the casing off you will be left with the motor inside a plastic unit
you then have to loosen the wire a bit to give you a bit of room to work
then you press the motor out via the side - ie where the belt goes on
the rubber bit will then come off leaving you with the motor.
putting it all back together - well thats another question -- lol
all i can say is good luck
