Beneath the aggressive sales model sits legitimate mechanical innovation. Traditional vacuums draw particulate matter into porous paper bags or cyclonic plastic chambers. As dust cakes the interior walls of a bag or canister filter, airflow chokes and suction drops. The Rexair water filtration vacuum operates on a fundamentally different principle: "Wet dust cannot fly."

Incoming air pulls debris straight down into a two-to-four-quart basin filled with plain tap water. Inside this churning bath, an aerodynamic dirt separator spins at approximately 23,000 RPM. This high-speed separator creates a violent water vortex that forces heavy particulate matter, hair, and grit into the water while preventing liquid from entering the motor housing. Because the water does not clog in the way paper pores do, suction volume remains static from the beginning of the chore to the end.

Water alone cannot catch everything. Sub-micron particles, ultra-fine combustion soot, and certain micro-allergens can escape within airborne bubbles before they become saturated. To solve this legacy flaw, modern units incorporate a rear-mounted HEPA neutralizing filter. The liquid basin captures roughly 98% to 99% of macro-debris, leaving the secondary HEPA media to catch remaining microscopic particles before clean exhaust returns to your living space.
