How does this top housing fit my Polaris 380 or 360?

The 9-100-1240 top housing is engineered to the same specifications as the original factory component, so it lines up with the same screw holes, seals, and mounting points on the Polaris 380 and 360 models. Installation typically requires removing the old or damaged housing and transferring any retained hardware or gaskets to the new part.

• Direct factory-compatible replacement for Polaris 380 and 360
• Matches mounting hole pattern and seal positions
• Works with Vac-Sweep 380 and Vac-Sweep 360 variants
• Replaces only the top housing — cost-effective repair

What should I check before ordering this replacement part?

Confirm the model number of your cleaner (380 or 360) and whether it’s a Vac-Sweep variant to ensure compatibility. Also inspect the existing housing for retained hardware, gaskets, or internal components you may need to transfer, and note any additional parts that may be worn or missing.

• Verify model: Polaris 380 or 360 (including Vac-Sweep versions)
• Inspect and note transferred screws, gaskets, or internal pieces
• Measure housing condition to avoid unrelated leaks or damage
• Keep service manual or parts diagram handy for reassembly

Will replacing the top housing improve cleaner performance?

Replacing a cracked or distorted top housing can restore a proper seal and alignment in the cleaner’s upper assembly, which helps maintain suction balance and debris collection. While the housing itself doesn’t change motor or sweep action, correcting leaks and misalignment removes common mechanical causes of reduced cleaning efficiency.

• Fixes air or water leaks caused by damaged housing
• Reestablishes proper geometry for internal components
• Helps the cleaner maintain designed suction and motion
• Prevents water infiltration to components not meant to be wet

How difficult is the installation and what tools are needed?

Installation is generally straightforward for anyone comfortable with basic pool-cleaner maintenance: remove the old housing, move over any reusable parts, seat new gaskets if needed, and fasten the replacement with the original screws. Typical tools are a screwdriver and possibly pliers; consult the cleaner’s parts diagram for torque recommendations and gasket seating tips.

• Basic tools: Phillips or flat screwdriver, pliers if needed
• Transfer existing gaskets or replace them for optimal sealing
• Follow parts diagram to align holes and internal components
• No special adhesives or permanent modifications required
