Vacuum cleaner with water filtration

Abstract

The present invention relates to a vacuum cleaner, in which circulates a flow of drawn-in air loaded with particles, between an inlet nozzle and an aperture communicating with a suction chamber. The vacuum cleaner includes a water-air separator intercalated between an upstream conduit and suction device, capable of orienting the gas phase into the suction chamber, and the particles into a tank. The invention relates to a heating body incorporated in the vacuum cleaner. The vacuum cleaner also includes a filament embedded in ceramic materials, and a spray chamber formed by a helical space between two bodies or casings nested into each other, at least one of the bodies or casings being a ceramic body incorporating, embedded, a metallic filament.
