Frequently Asked Questions

What is the Dolphin ProLine?

The Dolphin ProLine is Maytronics' premium lineup of robotic pool cleaners featuring commercial-grade dual motors, NanoFilters, and extended warranties up to 3 years. ProLine robots represent the highest tier of residential pool cleaning technology for 2026, delivering professional-level performance for homeowners.

Which Dolphin robots are in the ProLine lineup?

The Dolphin ProLine includes top-tier models such as the Dolphin Sigma, Dolphin Premier, and Dolphin Quantum. Each ProLine robot features commercial-grade motors, advanced filtration, and comprehensive cleaning coverage across floors, walls, and the waterline.

The ProLine focuses on maximum cleaning power with commercial-grade motors and NanoFilters for ultra-fine filtration. The Max-Series emphasizes ease of use with the exclusive MaxBin top-loading debris system for effortless filter maintenance. Both are Gen-2 lineups with upgraded features, but they cater to different priorities.

What is NanoFilter technology in Dolphin ProLine robots?

NanoFilters are an advanced filtration system exclusive to select Dolphin robots that captures ultra-fine particles standard filters miss, including algae, sand, pollen, and other microscopic debris.

Why should I choose a Dolphin ProLine robot?

ProLine robots are the best choice for pool owners who want the most thorough clean with the best warranty coverage. With commercial-grade dual motors, NanoFilters, and up to 3-year warranties, ProLine delivers the highest level of cleaning performance. They are ideal for larger pools, heavy debris, or anyone who wants the best Dolphin has to offer.

What warranty do Dolphin ProLine robots come with?

Dolphin ProLine robots include extended manufacturer warranties of up to 3 years from the date of purchase through authorized dealers like Poolbots. This is among the longest warranty coverage available in the residential robotic pool cleaner market, providing long-term peace of mind and protection for your investment.
