A:Answer The "dirt cup" is the entire clear plastic collection assembly on the vacuum cleaner. As per packaged instructions, you press the top dirt cup release button, pivot the cup, and lift the entire assembly out. Then, when holding the cup closely over a trash receptacle, open the bottom of the dirt cup by pushing the lower dirt cup door release lever. After emptying it, close the dirt cup door by pressing it firmly to secure at the front where the lever is. Then place the closed bottom of the dirt cup into the vacuum body first. Pivot the dirt cup and press frimly until it locks into place. Note: I have to run a paper-cloth- covered ruler up into and around in the collection assembly to get out all of the pet dander and hair since it won't fall out on its own. If your latching mechanism(s) is\are broken, you will have to arrange for repairs.
