Clearer water. A free weekend. A longer life.

NanoFilters™ change what the water looks like.
Standard panels hold leaves. NanoFilters™ hold the dust, pollen, sand and algae that mesh lets through, which is the difference between a clean floor and a pool that sparkles. Spares for the ProLine™, the one upgrade for the Escape and Cayman.

Dolphin accessories: frequently asked questions
Which accessories fit my Dolphin?
NanoFilters fit the Premier, Sigma, Quantum, Escape and Cayman. The weekly timer power supply is the Escape's add-on and the replacement for timer-equipped Dolphins. The Universal Caddy and both caddy covers fit every Dolphin. The UltraFilters kit converts bag-filter Dolphins such as the Nautilus Pool Up. Each product page lists the fit, and we confirm by serial number on request.
Are these genuine Maytronics parts?
Yes. Every accessory on this page is a genuine Maytronics Dolphin part or accessory sold by an authorized dealer, with the Maytronics part number on its page.
Do accessories ship free?
Yes. Accessories ship free from our warehouse to the lower 48 states, usually within one business day, with 30-day returns.
Which upgrade makes the biggest difference?
For water clarity, NanoFilters: they catch the fine dust, pollen and algae that standard panels miss. For convenience, the weekly timer power supply: it runs the robot on a schedule with no app. Most Escape and Cayman owners add both.
I need a replacement part, not an accessory. Where do I look?
The parts hub lists filters, brushes, tracks, cables and power supplies by robot, with Maytronics part numbers. Start at /parts/ and pick your Dolphin.
Upgrade the Dolphin you own, or pick the one that ships ready.
Every ProLine™ robot ships with NanoFilters™ and a weekly timer in the box. The Max-Series™ takes both as upgrades. Either way it ships free with a full Maytronics warranty.
