Manual aquatic vacuum cleaner for cleaning hydromassage spa baths and similar

Abstract

A manual water vacuum cleaner for cleaning a whirlpool spa bath or similar, comprising a suction hose with an end receiving a quick-connect adapter for coupling a corner vacuum nozzle or seat vacuum nozzle and the opposite end with a spigot coupling for assembling the accordion coupling, which can be coupled to the drainage drain of water evacuation of the hydromassage spa bath. The accordion coupling in the drainage drain, once open and suction between the diametrical narrowing provided between the drainage drain and hose configures the Venturi effect to suck up dirt accumulated on the sides, seats and bottom of the hydromassage spa bath.

1 - 2 . (canceled) 
     
     
         3 . A manual aquatic vacuum cleaner comprising:
 a suction hose comprising: an end and a first opposite end;   a quick-connect adapter removably attached to the end of the suction hose, wherein the quick-connect adapter is configured to selectively couple with at least one of: a corner vacuum nozzle and a seat vacuum nozzle; and   a spigot coupling attached to the first opposite end of the suction hose, wherein the spigot coupling is configured to connect to an accordion coupling ( 14 ), wherein the accordion coupling is adapted to be fluidly connected to a drainage drain (DN) of a hydromassage spa bathtub (BH) for evacuating water (AG) and dirt.   
     
     
         4 . The manual aquatic vacuum cleaner of  claim 3 , wherein the accordion coupling comprises a flexible body comprising:
 a central accordion section;   a first end with a first opening configured for connection to the drainage drain (DN); and   a second opposite end having a tubular projection with a second opening configured to receive the spigot coupling, wherein the second opening has a smaller diameter than the first opening.   
     
     
         5 . The manual aquatic vacuum cleaner of  claim 3 , wherein the suction hose is made of a polymeric material selected from one or more of: polyvinyl chloride (PVC), and polypropylene. 
     
     
         6 . The manual aquatic vacuum cleaner of  claim 3 , wherein the quick-connect adapter is configured to selectively couple either a corner vacuum nozzle or a seat vacuum nozzle, wherein the corner vacuum nozzle comprising a tubular body with a sector terminating in a rectangular extension having an oblique end adapted for vacuuming narrow spaces. 
     
     
         7 . The manual aquatic vacuum cleaner of  claim 3 , wherein the seat vacuum nozzle is comprised of the shape of a “T” with a central tubular extension to be coupled to the quick-connect adapter from which a perpendicular member with a rectangular cross-section develops and with a suction nozzle with an edge fitted with a brush to sweep the contact surface.
