How Does a Water Filtration Vacuum Cleaner Work?

When it comes to working, water filtration vacuum cleaners use water to trap dust and other waste inside the main tank. The dirty air comes inside from the main floor head where the dust settles with water. The moist air revolves in the container where spiral plastic filters catch the dust. Water drips back to the tank, and vacuum releases clean and fresh air. In simple steps:

  1. The vacuum sucks air containing the sand.
  2. The motor pulls the air and dust inside the water tank, where all the dust particles mix with water.
  3. The air, which is now moist because of the water content, will keep moving through the tank to pass some spiral plastic filters.
  4. The filters will separate the dust containing water droplets from the moving air, and water drips down to the tank. Now the air coming out of the vacuum is free from dirt and allergens.
