How It Works

Not Your Average Vacuum Cleaner

Unlike traditional vacuum cleaners, the Sirena vacuum uses water instead of bags and filters to trap dust, dirt, and allergens. The air is water-washed and vented fresh and clean back into your home.

Water Vacuum Technology

  • 1

    The powerful Sirena motor provides 1000W of suction power.

    Dust, dirt, pet hair, and other contaminants are sucked into the basin.

  • 2

    The basin holds up to 3.5 liters of clean water.

    Once the dirt hits the water it's trapped. The rapidly spinning separator prevents the water from entering the motor.

  • 3

    The air is vented through a HEPA filter.

    The washable HEPA filter captures the odd particles that didn't get trapped in the water basin (usually < 0.01% of all particles). The clean air is then vented out.

How To Use Your Sirena

Step 1: Fill The Basin

Begin by filling the basin with regular tap water. Make sure the water level is above the "MIN" line and below the "MAX" line. The "MAX" line is important to note if you're planning to pick up liquids with your Sirena. It indicates the maximum amount of liquid the basin can hold before it must be emptied. Otherwise, adding extra water above the "MIN" line will have little to no impact on the cleaning performance.


Step 2: Add Optional Fragrances Or Deodorizer

Add optional fragrances (from the Sirena Fragrance Pack) or a cap of our Ocean Breeze Deodorizer directly into the water before cleaning. This will help either aromatize the air or remove unwanted odors such as pet, smoke, or food. We do not recommend using third-party aromatizer or deodorizer solutions with your Sirena vacuum.


Step 3: Assemble Your Sirena Vacuum

Use the two clamps to secure the main Sirena unit to the water basin. Then put the unit with the basin attached onto the dolly. Attach the Power Nozzle or the wet/dry hose to the intake (or exhaust if you want to use the blower function) and you're ready to start cleaning!


Step 4: Harness The Power Of Nature To Clean Your Home

Mix and match hoses, extension wands, and attachments to reach everywhere and clean everything around the house. The floor brush works best on hard surfaces while the Power Nozzle is unmatched on carpets. Stacking all extension wands together will let you reach up to 12 ft (3.65 m) in the air. You can even connect a hose to the exhaust and turn your Sirena into a powerful blower!


Step 5: Look Inside The Basin To Find Out How Dirty Your Carpets Really Were

All done? Detach the main unit from the basin and take a look inside. Do you know the feeling of being simultaneously grossed out and immensely satisfied? That's what you'll experience when you see the water after using your Sirena vacuum for the first time. Remember, everything you see in the water was on your carpets, floors, and furniture!


Step 6: Discard The Dirty Water And Clean The Basin

There are 3 ways to discard the dirty water:

  • Dump the water outside in your backyard.
  • Flush the water in the toilet (in most cases it's completely safe and won't clog your pipes).
  • Carefully drain the water (tip: use cheesecloth or a strainer) and throw the leftover solid debris in the garbage (recommended if you're not comfortable flushing everything in the toilet).

Once you've discarded the dirty water, wash the inside of the basin with warm water and dry with a rug or let air dry. DO NOT store the basin attached to the main Sirena unit! Doing so will create an air-tight seal which will cause mold and mildew growth inside the basin over time and result in bad smell and discoloration of the plastic.
