1. Remove the screw in the top. I found a hex key of around 3/32" did the job (long handle).
2. Remove the wheels. You need two flat blade screwdrivers to remove the center insert of each wheel and a lot of force.
3. Pulling the wheel back as much as possible and you should be able to see inside the wheel.
4. You should be able with a screwdriver to push the plastic prongs that keep the wheel on.
5. Pull the wheel off.
6. Do the same both side.
7. Hidden inside the wheel space are 2 more screws each side. Remove with hex key.
8. The cleaner should now come apart (thats a total of 5 screws to remove).
Good luck!
