Hydraulic Timer Pool Cleaner for Continuous Vacuuming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pool cleaners often limit vacuuming to forward motion and require specific scrubber assemblies for operation, restricting their ability to effectively clean pool surfaces during backward and turning movements.
Innovation Solution
A pressure-driven pool cleaner with a timer disc assembly and thrust jets that redirect pressurized fluid for forward, backward, and turning motions, allowing independent suctioning during all movement states and eliminating the need for permanent scrubber assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vacuum systems are integrated with drive systems in pressure side cleaners and suction cleaners, then the drive system can provide propulsion, but vacuuming can only occur during forward motion limiting cleaning effectiveness during backward and turning movements
Solution Approach 1:
The drive system and vacuum system are separated into independent components. The drive system uses hydraulic turbines connected to drive wheels for propulsion, while the vacuum system uses a separate venturi vacuum assembly with its own suction inlet and debris bag. This allows the vacuum system to operate independently during forward, backward, and turning motions without being constrained by drive system orientation.
2Productivity
If scrubber assemblies are used as drive wheels in robotic cleaners, then the cleaner can be driven along pool surfaces, but the cleaner cannot operate without these scrubber assemblies present
Solution Approach 1:
The scrubber assemblies are removed from the drive system entirely. Instead, the patent uses hydraulic turbine assemblies connected directly to drive wheels for propulsion. The venturi vacuum assembly provides separate cleaning capability by suctioning debris into a debris bag. This extraction of scrubbers allows the cleaner to operate without them while maintaining both propulsion and cleaning functions.
3Device complexity
If conventional pressure-driven pool cleaners use integrated vacuum and drive systems, then the structure is simplified, but the vacuum system is restricted to forward motion only
Solution Approach 1:
The system is segmented into independent hydraulic turbine drive assemblies for propulsion and venturi vacuum assemblies for cleaning. The timer disc assembly controls hydraulic fluid distribution to thrust jets and turbine assemblies separately, enabling coordinated but independent operation. This segmentation allows vacuuming to continue during forward, backward, and turning motions without relying on integrated drive-vacuum coupling.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and directional cleaning of pool surfaces with enhanced suction capabilities during all movement states, improving cleaning coverage and efficiency while maintaining stability and preventing damage from large debris.
Implementation Method 1
a first thrust jet in fluid communication with the first outlet port, a second thrust jet in fluid communication with the second outlet port, and a third thrust jet in fluid communication with the third outlet port. The first thrust jet is positioned along the housing to direct pressurized fluid away from the rear of the housing to assist in forward motion of the pool cleaner.
Implementation Method 2
a turbine assembly which rotates in one of a first direction and a second direction to drive the at least one drive wheel
Implementation Method 3
a venturi vacuum assembly. The method also includes receiving water from one of a pool pump and a booster pump into the distributor manifold and directing the water from the distributor manifold to the hydraulic timer assembly and the venturi vacuum assembly.

AI summary
Embodiments of the invention provide a system and method for operating a pressure-driven pool cleaner. The system includes a hydraulic timer assembly and a venturi vacuum assembly. The method includes directing water to the hydraulic timer assembly and the venturi vacuum assembly, driving the pressure-driven pool cleaner with the hydraulic timer assembly according to a timed movement cycle including a combination of backward movement and forward movement, and suctioning debris with the venturi vacuum assembly. The venturi vacuum assembly is independent of the hydraulic timer assembly so that suctioning occurs during the backward movement and the forward movement.
