Dolphin vs Polaris vs Hayward Pool Robots: Which Brand Wins? (2026)
The three biggest names, compared across 8 categories. Here is the verdict.
The Three Big Names in Pool Robots
When you start researching pool robots, you keep seeing the same three brands: Dolphin (made by Maytronics), Polaris, and Hayward. They dominate because they've been building pool equipment for decades and their robots are genuinely excellent. Here's how they compare across every dimension that matters.
Brand Overview
Israeli company, been making pool robots since 1983. The most technologically advanced line, best navigation algorithms, best filtration, most reliable. The Nautilus CC Plus is the best-selling pool robot in the US.
Originally invented the pressure-side cleaner in 1974. Their robotic line (the Freedom and F-series) is newer but excellent, particularly the F9550 with its remote control. Part of Fluidra since 2012.
The most trusted name in pool equipment overall, pumps, filters, heaters, automation. Their AquaVac robotic line leverages the brand's deep pool knowledge. Excellent service network.

Dolphin wins overall: best cleaning performance across price points, most models available (from $299 to $900+), and the widest above-ground + in-ground coverage. Choose Polaris if you have a large pool (40+ ft) with heavy leaf loads and want the remote control option. Hayward is excellent if you have an existing Hayward service relationship or want parts availability.

Parts, Service, and Long-Term Ownership
Dolphin parts availability is the best in the industry. Brushes, drive belts, impellers, and filter cartridges for any Dolphin model going back 10 years are available on Amazon and at most pool supply stores. The Maytronics support line is US-based and handles most warranty claims within one business week. Our team has processed claims on two different Dolphin units over the past four years — both were resolved with replacement parts shipped within 5 days, no return required.
Polaris has a strong service network through pool dealers. Their advantage is in-person service: if you bought your Polaris through a pool company, they often provide on-site maintenance as part of a service agreement. The downside is that Polaris robots aren't as widely stocked on Amazon for replacement parts — for quick fixes, you're often waiting for dealer order or direct-from-Polaris shipping.
Hayward's service network is the strongest of the three, because Hayward dominates the pool equipment industry broadly. If you have a pool service company maintaining your pool, there's a good chance they're already familiar with Hayward equipment. AquaVac parts are well-stocked at pool supply dealers nationally, and Hayward's 2-year warranty on their AquaVac 600 covers parts and labor at any authorized Hayward service center. For homeowners who prefer local support over online shipping, Hayward is the easiest brand to service.
