Thomas Allergy and Family is a premium vacuum cleaner with an AQUA-BOX, turbo brush, and nozzles for parquet care. Allergy and Family is a high-quality German multifunctional vacuum cleaner with premium features and a unique Thomas AQUA-BOX water filter that cleans dust-laden air by 99.99% and pollen by 100%. The operating principle of the AQUA-BOX is based on wet-jet dust suppression technology, which creates the so-called rain effect. The air that enters the vacuum cleaner flows through a water wall, causing the dust to become wet, heavy, and sink to the bottom of the water box.
