Hayward PHS41CST AquaNaut Suction Pool Vacuum (Automatic Pool Cleaner)

Matching the AquaNaut PHS41CST

This is a suction-side automatic cleaner identified as model PHS41CST and size 400. The listing emphasizes turbine, tire, skirt, steering, and throat features rather than robotic battery operation.

• Debris and flow: The listing says V-Flex variable vane turbine technology eliminates clogs and maximizes power at almost any flow. It also lists three interchangeable throats for variable-speed pool pumps.
• Surface contact: The listed features include high-traction tires, an adjustable roller skirt for uneven surfaces, and multiple pre-programmed steering sequences for coverage. Confirm these match the cleaning challenges in your pool before choosing this model over a different AquaNaut variant.

Use the full model number when checking parts or service details, because size-only references may not identify the exact cleaner.
