Solution Overview
Problem
Existing manually operated pool cleaners require an external garden hose to create a Venturi effect for suction, leading to inefficiencies due to unpredictable water pressure, cumbersome handling, and wasteful water use, which increases operating costs and reduces user convenience.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an external garden hose is used to create a Venturi effect for suction, then water and debris can be drawn into the cleaner, but the system becomes cumbersome and inefficient due to unpredictable water pressure, difficult handling, and continuous water waste
Solution Approach 1:
The patent extracts the water source requirement from the external environment and replaces it with an internal pump system. The pump is integrated directly into the cleaner housing, eliminating the need for an external garden hose connection. This allows the cleaner to operate independently without being constrained by external water pressure variations or hose handling issues.
Solution Approach 2:
The cleaner becomes self-sufficient by incorporating its own pump and power source (battery). The system serves itself by drawing water directly from the pool through its own pumping mechanism rather than relying on external water supply. This self-service capability eliminates dependency on external infrastructure and improves operational independence.
2Reliability
If an external garden hose is used to supply water, then suction can be generated, but water pressure variations from other home water uses cause poor cleaning results and longer cleaning times
Solution Approach 1:
The patent removes the cleaner's dependency on the home's main water supply system by extracting the water intake directly from the pool and using an internal pump. This extraction eliminates the interference from other water-using appliances (dishwashers, sprinklers, etc.) that cause pressure fluctuations in the municipal supply, ensuring consistent suction performance regardless of other water activities in the home.
Solution Approach 2:
The pump system operates with controlled suction that is not subject to external pressure feedback loops. Unlike the garden hose system where suction depends on external water pressure that fluctuates with home water usage, the pump provides active, controlled suction that maintains consistent performance. The pump can regulate its own operation to maintain reliable suction independent of external conditions.
3Ease of operation
If a garden hose is used with the cleaner, then water flow can be provided, but the hose is difficult to maneuver, prone to kinking, and requires continuous connection and disconnection which is time-consuming
Solution Approach 1:
The patent extracts the water supply function from the external garden hose and relocates it to an internal pump system integrated into the cleaner. This eliminates the physical hose that requires connection and disconnection. The cleaner can be deployed and retrieved without any hose attachment steps, significantly reducing setup and teardown time.
Solution Approach 2:
The cleaner operates as a self-contained unit with its own water pumping capability. It does not require external service connections for water supply during operation. The battery-powered pump provides all necessary water circulation functions independently, eliminating the need for user intervention to connect or manage water supply lines.
4Productivity
If continuous water flow from a garden hose is used, then debris can be drawn into the cleaner, but cold water continuously adds to the pool volume and lowers water temperature
Solution Approach 1:
The patent extracts the water circulation function from the external garden hose supply and replaces it with an internal pump that recirculates pool water. Instead of introducing continuous cold external water, the pump draws water from the pool, passes it through the cleaning mechanism, and returns it to the pool. This eliminates the temperature dilution effect while maintaining effective debris removal capability.
Solution Approach 2:
The system recovers and recirculates pool water rather than discarding it as continuous fresh water flow from a garden hose. The pump intake draws water from the pool bottom or surface, uses it for the cleaning process, and the water is returned to the pool. This recovery approach prevents continuous addition of cold water that would lower pool temperature and increase volume.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides efficient and reliable debris removal without the need for external water sources, reducing operating costs and improving user convenience by ensuring consistent cleaning performance and minimizing water waste.
Implementation Method 1
an impeller for drawing water and debris from the surface of the pool
Implementation Method 2
a Venturi effect is created by the high velocity, low pressure water flow. The low pressure zone draws water and any associated debris situated below the cleaner upwardly through the opening (inlet)

AI summary
An electric-powered submersible pool cleaner includes a base, discharge conduit, and outwardly extending flange. The base includes an inlet port, and the discharge conduit extends upwardly from the base and circumscribes the inlet port and a portion of an electric-powered impeller to direct the flow of water and debris drawn through the inlet. The outwardly extending flange extends from an upper portion of the discharge conduit and secures a filter to filter debris and pass clean water back into the pool. The impeller includes one or more blades having leading and trailing edges and is set at a height such that the leading edges of the blades are positioned to extend into the discharge conduit below a lower portion of the outwardly extending flange and the trailing edges of the blades extend above the lower portion of the outwardly extending flange. A handle provides maneuverability of the cleaner.
