As a protective measure, the first thing we need to do is unplug the Clean Base from the wall.
To unclog the clean base, we need to access the automatic dirt disposal tube on the bottom of the base. To do this, simply turn the Clean Base on its side.
If your Clean Base is clogged, it's likely the clog is in the tubing underneath. Fortunately, the tube is clear, so you should be able to easily find the clog.
Unscrew the five screws securing the tube to the bottom of the Clean Base. Once you remove the screws, you can remove the tube by pressing the tube out from the top.
With the tube removed, you can easily access the debris and unclog the tube.
