You'll need: A Phillips-head screwdriver, and a flat-head screwdriver.
First, make sure your machine is turned off, and unplugged.
Remove the clean water tank.
Now, remove the screw on the back of the carry handle with a Phillips-head screwdriver, twisting counter-clockwise. Using your thumb as leverage, pull outwards on each side of the carry handle to remove.
Next, use a flathead screwdriver to pry up both sides of the plastic cover at the base of the handle. Then pull up on the upper handle until it releases from the machine.
You now have your machine disassembled!
