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-Based Vacuum Technology

  • 1

    The powerful Sirena motor provides 1200W 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. You can also add optional fragrances (from our Fragrance Pack) or a cap of our Ocean Breeze Deodorizer directly into the water before cleaning.


Step 2: Attach The Main Unit To The Basin

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. Connect the Power Nozzle or the wet/dry hose to the intake and you're ready to start cleaning!


Step 3: Use Different Attachments To Clean Your Entire 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 4: 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 5: 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) and throw the leftovers in the garbage (recommended if you're not comfortable flushing everything in the toilet).
