<p>The invention discloses a suction device for thoroughly cleaning the bottom surface of a structure, covered with a non-porous plastic liner, that contains a body of water larger than 15,000 m3 for recreational use with color, transparency and cleanness characteristics similar to swimming pools or tropical seas at low cost, the device operating by suctioning impurities from the bottom surface by a pumping system of the structure. The device comprises a structural frame (10), a cover (6) comprising one or more suction connection pipes (8) that couple to the pumping system, a propelling device to move the suction device around the bottom surface of the structure. Rollers (11) or wheels (12) are provided for continuous movement of the suction device over the bottom surface to be cleaned. The device further comprises a fixed brush line (16) to remove precipitated impurities from the bottom surface of the structure, and bottom suction pipes (27) to allow suctioning the impurities from the bottom surface of the structure.</p> |
