How It Works

Harness The Power Of Nature

Like Mother Nature, Sirena uses water as its filter. Separator technology forces air into the water, keeping dirt from being exhausted into your air. Dirt is trapped within the water. The air in your home is water-washed, and returned fresh and clean.

Water-based filtration technology for superior cleaning performance

Unlike traditional vacuum cleaners, Sirena doesn't require bags to collect dust and dirt. A large 3.5L basin filled with water is where all dust and dirt gets trapped. Water never clogs the way most bags, or filters in bagless vacuums, do. Sirena cleans 100% of the time — at 100% efficiency.

When the air is pulled inside, it is forced to pass through the water where the contaminants (e.g. dust, pet hair, dust mite droppings, etc.) are trapped in a swirling bath of water. A rapidly spinning separator prevents the water from entering the motor. The air is then forced through a washable HEPA filter which retains anything that didn't get trapped in the water (usually less than 0.01% of all particles). Finally, the clean, water-washed air is exhausted back into the room.

Vacuuming with Sirena is a breeze. 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.

Adding fragrances or deodorizer doesn't affect the cleaning efficiency. You can also switch the scents half-way through. Simply inject a few drops directly into the intake, there is no need to turn the machine off or to open the basin! Our Fragrance Pack includes four natural fragrances: Pine/Tropical/Apple/Eucalyptus.

Sirena's water basin is designed to protect the motor from being damaged by large debris entering the machine. A special baffle is located right behind the intake port to help keep large debris away from the separator and to intensify the "rain storm" inside the basin.

Sirena's large 3.5L basin allows you to clean the entire house without needing to replace the water. When you have finished cleaning, detach the basin and pour the dirty water (it will be very dirty the first time you use Sirena) down the toilet or outside.

We want your Sirena to last a very long time! It is designed with safety and longevity in mind. The motor is bypass-cooled, so it will never overheat. Sirena also features an interlock system which prevents it from turning on if the water basin is not attached.
