How do i remove the hood for cleaning out debris?

There should be three screws on this unit to remove the clear plastic hood.

first, remove the dirty water container, there will be one screw there to remove. It should be rather long.

next turn the machine over, there will be 2 more screws under the corners of the front of the machine (you can see the threads through the plastic on the top) remove the two screws.

Now comes the tricky part. Turn the machine back over so that its the right side up again, you will want to pull away from the machine and up, kind of like you are going to bend the plastic up. Once you have that done the entire cover will come off.

Good luck,
Mark
