To empty the Armor All AA155 wet dry vacuum, unplug the unit, release the side latches, remove the motor head, and pour the collected debris or liquid into a proper disposal area. Afterward, clean the tank, inspect the filter, and reassemble everything securely before the next use.
Regular maintenance helps any wet dry vacuum perform better and last longer. According to industry studies, routine vacuum maintenance can improve airflow by up to 30%, while clogged filters often reduce cleaning efficiency significantly. Many owners of the Armor All AA155 portable wet dry vacuum find that emptying the tank immediately after each job keeps suction strong and prevents unpleasant odors from developing inside the container.
Why You Should Empty the Vacuum Regularly
A full collection tank reduces airflow and lowers suction performance. Therefore, frequent emptying keeps the vacuum working efficiently during every cleaning session.
Wet debris also creates odors when left inside the tank too long. As a result, quick cleaning prevents mold growth and unpleasant smells.

What You Need Before Emptying
Prepare everything before opening the vacuum. This simple step keeps the process cleaner and much faster.
- Protective gloves
- Trash bag or garbage bin
- Drain location for liquids
- Clean cloth
- Mild soap and water
How to Empty Armor All AA155 Wet Dry Vacuum
Step 1: Turn Off the Vacuum
Switch off the vacuum completely before starting. Then unplug the power cord from the electrical outlet for safety.
Step 2: Move to a Disposal Area
Carry the vacuum near a trash container or drain. Consequently, cleanup becomes easier and prevents accidental spills indoors.
Step 3: Release the Side Latches
Locate the two side latches securing the motor head. Next, unlock both latches carefully without forcing them.
Step 4: Remove the Motor Head
Lift the motor housing straight upward using both hands. Place it safely on a dry, stable surface.
Step 5: Empty Dry Debris
Hold the collection tank over a garbage container carefully. Shake the tank gently until all dirt and debris fall out.
Step 6: Empty Collected Liquids
Pour collected liquids into an approved drain slowly. Avoid splashing because dirty water may contain harmful contaminants.
Step 7: Rinse the Tank
Wash the inside using warm water and mild soap. Afterwards, rinse thoroughly to remove remaining residue.
Step 8: Let the Tank Dry
Allow every surface to dry completely before reassembly. Moisture left inside encourages mildew and unpleasant odors.
Step 9: Inspect the Filter
Check the installed filter for dirt or damage. Clean or replace it whenever necessary for the best airflow.
Step 10: Reassemble the Vacuum
Place the motor head back onto the tank carefully. Finally, lock both side latches securely before storing the vacuum.
How to Empty Wet Debris Safely
Always wear gloves when handling dirty water from the vacuum. This habit reduces direct contact with bacteria and contaminants.
Dispose of wastewater according to local regulations whenever required. Never pour hazardous materials into household drains.
How to Clean the Collection Tank
Cleaning the tank removes residue that affects future performance. Fortunately, the process only takes a few minutes.
- Rinse thoroughly with warm water.
- Wash using mild dish soap.
- Wipe stubborn residue gently.
- Dry completely before storage.
How Often Should You Empty the Vacuum?
Empty the tank after every major cleaning project. This routine keeps suction consistent throughout future cleaning tasks.
Check the fill level during larger jobs involving heavy debris. Emptying earlier prevents reduced airflow and possible overflow.
Common Mistakes to Avoid
- Opening the vacuum while plugged into power.
- Storing the vacuum with standing water inside.
- Ignoring dirty or damaged filters.
- Overfilling the collection tank.
- Reassembling before every part dries completely.
Signs the Vacuum Needs Emptying Immediately
Several warning signs indicate the tank has reached capacity. Recognizing them early prevents unnecessary strain on the motor.
- Reduced suction power
- Higher operating noise
- Noticeable unpleasant odors
- Visible debris reaching the fill level
- Water approaching the maximum capacity mark
Maintenance Tips After Emptying
Inspect the hose for blockages before storing the vacuum. Clean airflow supports stronger suction during the next use.
Store the vacuum in a cool, dry location afterward. Proper storage protects electrical components and extends overall service life.
Troubleshooting After Emptying
Weak Suction Continues
Inspect the filter, hose, and nozzle carefully for remaining blockages. Replace damaged parts if cleaning does not restore airflow.
Latches Will Not Close
Check whether the motor head sits evenly on the tank. Then press both sides gently until the latches lock.
Bad Smell Remains
Wash the tank again using mild soap and warm water. Dry every component completely before the next use.
Conclusion
Learning how to empty Armor All AA155 wet dry vacuum correctly protects its performance and extends its lifespan. Regular cleaning also prevents odors, improves airflow, and keeps every cleaning session more effective.
