I was intrigued so urned to G**gle and put in "Dyson DC15 remove" and got to the following:
Unwrap the cord from the backside of the Dyson DC15 Ball. If the machine is plugged in, unplug it now.
Press the wand release catch, located just below the handle, and detach the wand and hose from the machine.
Press the two retaining clips located beneath the wand release catch, and separate the top of the hose from the wand.
Rotate the base of the hose downwards, away from the machine, until it clicks.
Twist the base of the hose clockwise to remove this end of the hose from the Dyson DC15.
