Hayward / Poolvergnuegen PBS20JSTHBX 2-Wheel Cleaner Headbox (Head-Only)

SKU/Part Number: PBS20JSTHBX
Vendor/Brand: Hayward / Poolvergnuegen
Condition: New

Product Overview

The Hayward PBS20JSTHBX is an OEM replacement headbox (internal cleaner assembly) for the 2-Wheel suction side PoolCleaner lineup. If the head of your Poolvergnuegen cleaner (models like PBS20JST or W3PVS20JST) is worn out, cracked, or performing poorly, this head-only unit restores full suction, steering, and debris pickup—without needing to replace hoses or the full cleaner. Built with rugged materials, it offers durability in harsh pool conditions and extends your equipment’s lifespan.

Key Features

• Complete Internal Cleaner Assembly – All critical internal parts included: steering/mechanism, self-adjusting turbine vanes, regulator/bypass valve, vacuum lock, universal hose adapter, dual throats. 

• OEM Genuine Headbox – Designed by Hayward/Poolvergnuegen for compatibility with original cleaner models for reliable fit & operation. 

• Steering & Flow-Adaptive Vanes – Turbine vanes adjust to incoming flow; steering system ensures good coverage of pool surface. 

• Durable Construction – Engineered to resist UV, pool chemicals, and wear from debris; built for long operational life. 

• Cost-Effective Repair Option – Head-only replacement saves you from buying full cleaner if hoses, body frame, and accessories are still usable. 

What’s Included

• (1) Headbox Assembly – internal cleaner head for 2-Wheel suction system (PBS20JSTHBX) 

• Regulator / Bypass Valve Vacuum Lock 

• Universal Hose Adapter 

• Two interchangeable throats 

Technical Specs

• Part Number: PBS20JSTHBX 

• System Compatibility: Hayward / Poolvergnuegen 2-Wheel suction side cleaners (e.g. PBS20JST, W3PVS20JST)

• Included Accessories: Head components listed above; does not include hoses 

• Material & Durability: OEM grade plastics, resistant to pool chemicals and UV exposure; internal parts designed for reliable performance. 

• Operation: Works via pool’s suction line / filter pump; requires proper suction flow and regulator valve or bypass to avoid overloading or underperforming.

• Warranty: Manufacturer’s limited warranty. Check Hayward’s warranty terms.

Ideal For

• Pool owners whose 2-Wheel suction cleaner’s head is damaged but hoses etc. are still usable.

• Those who want to restore performance without buying an entirely new unit.

• Residential pool setups where standard suction-side cleaners are used.

• Situations where steering, suction and coverage are suffering due to worn or missing internal parts.

Installation & Warranty Guidance

• Installation: Headbox replacement can often be done by a knowledgeable homeowner or standard pool technician. Basic tools may suffice; no full system re-plumbing needed if hoses, body, and cleaner frame are intact.

• Hoses and Accessories: Not included; ensure existing hoses fit or order separately. Use correct hose diameter + skimmer connection.

• Warranty: Warranty may require proof that parts are genuine OEM and installed properly. Retain receipts. Contact Hayward for terms.

Compliance & Notes

• Designed for suction side systems only — requires adequate pump/filter flow. Using without regulator / bypass valve can lead to poor performance or damage. 

• No hoses included — existing hoses must be in good condition; leaks or cracks in hoses will reduce cleaning efficiency.

• Not a motorized or robotic cleaner — relies entirely on pool suction and flow for operation.

• Chemical exposure (pH balance, sanitizers) influences lifespan of plastic components; regular maintenance helps.

Customer Q&A

Q: Will this head unit work if my cleaner body is cracked or wheels broken?
A: Only if the rest of the body frame and hoses are intact. This head-only unit replaces the cleaner’s full head unit. If those are damaged, you’ll need a more complete replacement.

Q: Can I use this with any suction pump flow?
A: It requires a suction pump with enough flow and a regulator/bypass valve to keep suction at optimal levels. Low flow or missing regulator will reduce cleaning performance.

Q: Does this restore the cleaner to like-new suction power?
A: In many cases yes — replacing worn internal vanes, steering and throats can significantly improve debris pickup and navigation. But overall performance also depends on hose condition, filter & pump condition, and pool surface/shape.
