What Comes Inside the Box
Begin by unpacking every component carefully before assembly. Place all parts on a clean, flat surface for easier inspection.
Most packages include the vacuum tank, motor head, hose, extension wands, utility nozzle, floor nozzle, cartridge filter, foam sleeve, caster wheels, and owner’s manual. Check each item for shipping damage before continuing.

Prepare Your Workspace
Select a dry, open area with enough room for assembly. Good lighting also helps identify every connection point correctly.
Keep children and pets away during setup for better safety. Additionally, avoid placing small accessories where they could become misplaced.
How to Assemble the Vacuum
Install the Caster Wheels
Turn the collection tank upside down on a soft surface. Press each caster firmly into its socket until fully seated.
Rotate every wheel by hand after installation. Each caster should move freely without excessive resistance.
Attach the Power Head
Return the tank to its upright position before installing the motor head. Align the top assembly carefully with the tank opening.
Next, secure the side latches tightly on both sides. Confirm each latch locks completely before moving forward.
Install the Correct Filter
Dry cleaning requires the cartridge filter for proper dust collection. Wet pickup requires replacing it with the supplied foam sleeve.
Never operate the vacuum without the correct filter installed. Doing so may reduce performance and damage internal components.
Connect the Hose and Accessories
Insert the hose into the inlet port until it locks securely. Twist gently if necessary to ensure a firm connection.
Attach the desired cleaning accessory to the hose end afterward. Extension wands increase reach for floors and ceilings.
Common Attachments and Their Uses
- Utility nozzle for general debris collection.
- Floor nozzle for smooth flooring surfaces.
- Crevice tool for narrow spaces.
- Extension wands for extended cleaning reach.
Prepare the Vacuum for Dry Cleaning
Install the cartridge filter before collecting dust or dirt. Ensure the filter sits securely on the filter cage.
Replace dirty filters when airflow decreases noticeably. Regular maintenance also improves suction and extends equipment life.
Prepare the Vacuum for Wet Pickup
Remove the cartridge filter before vacuuming liquids. Install the foam sleeve according to the instruction manual.
Empty the collection tank immediately after wet cleaning. Moisture left inside may create unpleasant odors over time.
Check the Power Supply
Inspect the power cord before plugging the vacuum into an outlet. Never use damaged cords or loose electrical connections.
Choose a grounded outlet that matches the manufacturer’s electrical requirements. This practice supports safe daily operation.
Perform the First Test Run
Turn the power switch on after completing assembly. Listen for smooth motor operation without unusual sounds.
Test suction using a small amount of dry debris first. Then verify every attachment remains securely connected during operation.
