Automatic swimming pool cleaner for swimming pools and spas

Abstract

An automatic swimming pool cleaner generally includes a body and one or more turbines. The one or more turbines may be positionable on a bottom portion of the automatic swimming pool cleaner. In certain aspects, each turbine of the one or more turbines includes a plurality of blades arranged around a center axis of the turbine. Each turbine of the one or more turbines may include a non-uniform height, and a maximum height of the plurality of blades is at the center axis.

That which is claimed: 
     
         1 . A turbine positionable on a bottom portion of an automatic swimming pool cleaner (APC), the turbine comprising a plurality of blades arranged around a center axis of the turbine, and wherein the turbine comprises a non-uniform height and a maximum height of the plurality of blades is at the center axis. 
     
     
         2 . The turbine of  claim 1 , wherein the turbine further comprises a shaft, a body comprising the plurality of blades at a first end of the shaft, and a gear at a second end of the shaft. 
     
     
         3 . The turbine of  claim 2 , wherein the gear is a miter gear. 
     
     
         4 . The turbine of  claim 1 , wherein the turbine comprises a domed profile. 
     
     
         5 . The turbine of  claim 1 , wherein each blade extends outwards from the center axis and comprises a non-linear profile. 
     
     
         6 . The turbine of  claim 1 , wherein each blade of the plurality of blades comprises a convex curvature. 
     
     
         7 . The turbine of  claim 1 , further comprising a brush extension extending outwards from one blade of the plurality of blades. 
     
     
         8 . The turbine of  claim 7 , wherein the brush extension is removable from the one blade of the plurality of blades. 
     
     
         9 . An APC comprising the one or more turbines of  claim 1 . 
     
     
         10 . An automatic swimming pool cleaner (APC) comprising:
 a body configured to travel along a surface of a pool to be cleaned, wherein the body comprises a wheel perimeter at an end of the body; and   a turbine on a bottom portion of the body, wherein the turbine comprises a non-uniform height such that the turbine is within the wheel perimeter.   
     
     
         11 . The APC of  claim 10 , further comprising two wheels, wherein each wheel is at an opposing end of the body and defines the wheel perimeter. 
     
     
         12 . The APC of  claim 10 , wherein the turbine comprises a plurality of blades arranged around a center axis of the turbine, and wherein a maximum height of the plurality of blades is at the center axis. 
     
     
         13 . The APC of  claim 12 , further comprising at least one brush extension extending outwards from at least one blade of the plurality of blades. 
     
     
         14 . The APC of  claim 10 , wherein the turbine comprises a domed profile. 
     
     
         15 . An automatic swimming pool cleaner (APC) comprising:
 a body configured to travel along a surface of a pool to be cleaned;   a turbine on a bottom portion of the body, wherein the turbine comprises a plurality of blades with a non-uniform height and a maximum height of the plurality of blades is at a center axis of the turbine; and   at least one brush extension extending outwards from at least one blade of the plurality of blades.   
     
     
         16 . The APC of  claim 15 , further comprising a skirt attached to the body, wherein the skirt is movable between a closed position and an open position, wherein, in the open position, the skirt is configured to redirect water flow from the turbine. 
     
     
         17 . The APC of  claim 16 , further comprising a wheel perimeter at an end of the body, wherein, in the open position, the skirt extends outside of the wheel perimeter. 
     
     
         18 . The APC of  claim 15 , wherein the at least one brush extension is removable from the at least one blade of the plurality of blades. 
     
     
         19 . The APC of  claim 15 , wherein the at least one brush extension is monolithic with the at least one blade of the plurality of blades. 
     
     
         20 . The APC of  claim 15 , wherein the turbine comprises a domed profile.
