Keeping an automatic pool cleaner running reliably is cheaper and less frustrating than replacing the whole unit. This guide highlights replacement parts and accessories that restore performance, extend life, and solve common failures—from torn filter bags and worn tires to frayed communication cables. Recommendations come from hands-on testing, compatibility checks, and consumer feedback.
How we tested and chose parts
What we evaluated: durability, compatibility, ease of installation, materials, and real-world performance. We tested parts on common pool cleaners (Polaris and Dolphin series where relevant), inspected build quality, and timed installation. We also reviewed hundreds of user reports and vendor specs to confirm fitment claims.
Why these factors matter:
- Durability indicates long-term value in chlorinated water.
- Compatibility prevents wasted purchases and ensures plug-and-play installation.
- Ease of installation matters to homeowners who want simple maintenance.
- Real-world feedback from owners highlights recurring failure modes and hidden tips.
Decision process: We combined hands-on results with aggregated user feedback and technical specs, prioritizing parts that reliably restore cleaner performance or prevent frequent service calls.
Polaris Tail Scrubbers
A budget-friendly 12-pack of polyurethane sweep hose scrubbers that restore traction and agitation on Polaris sweep hoses. Easy to install and elastic enough to fit a range of models, these are a low-cost way to return cleaning power to older sweep hoses.
These 12 polyurethane tail scrubbers are the go-to inexpensive fix for worn Polaris sweep hoses. They’re resilient, elastic, and replace the foam collars that grip pool surfaces and stir debris. Installation is straightforward—twist them onto the hose ends—making them ideal for quick maintenance. Expect to reclaim lost scrubbing action and reduce missed debris for a small investment. Note: they arrive vacuum-compressed; allow time to expand or soak in warm water if needed.
Gearwiz Dolphin Cable
A premium 60 ft communication cable replacement for select Dolphin Nautilus models, featuring two large floats and a swivel for tangle-free operation. Built to OEM-style standards, it restores robot connectivity and reduces drag—ideal for costly Dolphin repairs.
If your Dolphin Nautilus CC Plus (non-WiFi) or M200 is underperforming due to a damaged cable, this 60-foot aftermarket replacement is a high-quality option. It includes two big floats and a swivel for smoother rotation and reduced tangling compared with one-float replacements. The cable is engineered to OEM tolerances and improves communication reliability and robot range. Important: verify model compatibility—the cable does NOT work with WiFi variants or Nautilus CC Supreme. At a higher price, it’s a targeted, premium fix that avoids expensive service or replacement.
Keptwell Zippered Bags
Reusable zippered nylon filter bags built for Polaris 360 & 380 models with square-prong columns. Double-weave mesh captures fine debris (≈90 microns) and the zip design simplifies cleaning—good durability and strong filtration at a reasonable price.
These Keptwell zippered filter bags balance filtration and convenience. Specifically designed for Polaris 360 & 380 cleaners with square-prong clip columns, they capture fine debris down to roughly 90 microns while the zipper makes emptying and rinsing easy. Constructed from heavy-duty double-weave nylon with reinforced stitching, they’re reusable and cost-effective versus disposable options. If you own a compatible model, these bags improve clarity and save money over time—just confirm the prong-style fit before buying.
MUSCCCM Tire Tracks
A 2-pack of heavy-duty replacement tire tracks for MX6/MX8 Elite models. Made from abrasion-resistant rubber, they restore traction and extend coverage—an excellent repair to recover lost mobility and efficiency in robot cleaners.
Worn traction bands are a top cause of poor navigation and missed spots. These MUSCCCM replacement tire tracks (6" OD, 5.5" ID, 1.2" width) are made from tough rubber that resists pool-chemical degradation and abrasion. They slip on without tools and immediately restore grip, enabling more consistent wall and floor coverage and fewer dead zones. For owners of MX6/MX8 series cleaners, replacing old tracks is one of the most impactful maintenance steps you can take—this pair delivers OEM-style performance at a fraction of a new-unit price.
Comparative overview — key differences
- Polaris Tail Scrubbers (Best Budget Pick) — Cheapest fix for worn sweep hoses; bulk pack for multiple repairs; basic polyurethane foam. Best when you need an inexpensive, quick restore of sweep action.
- Gearwiz Dolphin Cable (Premium Choice) — High‑quality 60 ft communication cable for Dolphin Nautilus CC Plus (non-WiFi) and M200 with 2 floats and swivel. Best for costly communication or drag issues and when OEM-equivalent reliability matters.
- Keptwell Zippered Bags (Best Value for Money) — Durable, reusable filter bags for Polaris 360/380 that capture fine debris; zipper speeds cleaning. Best value for owners who need better filtration and lower long-term costs.
- MUSCCCM Tire Tracks (Editors Choice) — Heavy-duty rubber tracks that restore traction and coverage for MX6/MX8 cleaners. Best maintenance upgrade to regain lost mobility and cleaning efficiency.
Best overall: MUSCCCM Tire Tracks — they address a common failure that directly affects cleaning coverage and are an inexpensive way to bring a cleaner back to near-new performance.
Best alternatives for specific needs:
- Need the lowest upfront cost for routine maintenance: Polaris Tail Scrubbers.
- Fixing a high-value Dolphin robot with cable failures: Gearwiz Dolphin Cable.
- Improve filtration and reduce ongoing costs: Keptwell Zippered Bags.
Final recommendations
All four parts solve common, high-impact problems: traction loss, filtration failure, hose abrasion, and cable damage. For most owners looking for the single most effective repair, replacing worn tire tracks is the best starting point—better traction improves coverage and reduces repeat cleanings. If you’re on a tight budget or performing seasonal maintenance, the Polaris tail scrubbers provide the greatest immediate bang for your buck. Owners of Dolphin robots with damaged tether cables should invest in the Gearwiz cable to avoid costly diagnostics or replacement units. If filtration and water clarity are your priority, the Keptwell zippered bags offer long-term savings and improved debris capture.
Our recommendations are based on compatibility verification, physical inspections, practical installation tests, and aggregated user experience. Choose the part that matches your cleaner model and the failure mode you’re seeing—doing the right targeted repair typically restores performance at a tiny fraction of a new robot’s cost.
