Abstract: A device for mixing-dosing liquid cleaning products with water or other carriers is disclosed. The device comprises a body with a cover, which is fixed and hermetically sealed to a flask containing a series of doses of liquid concentrated cleaning products diluted in the water in the act of use. A venturi is incorporated into the body with a cover and includes a water entry that receives a hose with the opposed end having easy coupling to a tap. An orthogonal hole is formed in the entry, with the hole opening in the interior of the flask and gauged to join the water flow with the appropriate quantity of the cleaning product.
