Sirena’s water-based filtration makes it a fundamentally superior vacuum. 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 never clogs the way bags and filters do. Sirena cleans 100% of the time — at 100% efficiency.
