No recharging. No constant pulling the robot out of the pool. Just set it and forget it. Taking an in-depth look at one of the BEST robotic pool cleaner on the market - the ProLine's Dolphin Sigma. This isn't just another pool robot - it's a GAME CHANGER.

Built on Maytronics' commercial-grade ProLine platform (the same one used in the $2,500 Wave 80!), the Sigma crushes the competition with THREE commercial motors and a gyroscope. The results? Absolutely jaw-dropping. This beast filters over 75 gallons per minute - nothing else even comes close!

WHY THE SIGMA DOMINATES:
THREE Commercial-Grade Motors (4,500+ gallons/hour!)
Built-in Gyroscope for precision navigation
MyDolphin Plus App with FULL automation
Weekly Smart Timer (set it and forget it!)
Superior NanoFilters capture microscopic particles
Waterline cleaning with Dual Stabilizer technology
No recharging hassles - superior corded power
3-Year Warranty (50% longer than standard)

If you've struggled with pressure-side cleaners, suction-side models, or been disappointed by cordless robots that need constant charging, the Sigma will blow you away. After testing dozens of pool robots, I can confidently say this is in a league of its own.

The MyDolphin Plus app transforms your pool cleaning experience - schedule cleanings, control remotely, and track performance metrics. Forgot to start a cleaning cycle before leaving for vacation? No problem! Just open the app from anywhere and you're covered.

FILTRATION THAT SETS NEW STANDARDS
The dual-filter system with Gen-2 NanoFilters captures EVERYTHING - from leaves to microscopic dirt particles. Top-loading design means easy access and cleaning without flipping the robot over.

Compared to other Dolphin models like the Premier, or any cordless robot on the market, the Sigma's combination of power, precision, and automation is untouchable. It's the difference between "good enough" and "wow, that's spotless."

Yes, it's an investment - but after seeing what it can do, you'll wonder how you ever lived without it. This commercial-grade performance combined with residential convenience delivers a level of clean that is a level above.
