Designed for use in fountains, wading pools, and reflection pools, with the capability to function in water as shallow as 8 inches
Infinity edge (vanishing edge) pools are some of the most beautiful—and most difficult—pools to clean. You're dealing with continuous water overflow that constantly moves debris toward the edge, complex shapes and slopes near the vanishing edge, and higher cleaning demands due to the pool's design. Entry-level robots completely fail in infinity pools. The constant debris movement, complex geometry, and demanding cleaning requirements mean you need a premium robot with commercial-grade power and advanced navigation.
The defining feature of an infinity pool—continuous water overflow at the vanishing edge—creates a unique cleaning challenge. Water flow pushes debris toward the edge constantly. While the catch basin handles some of this, fine debris, sediment, and organic matter accumulate near the edge and along the pool floor faster than in a conventional pool. You need a robot with strong, consistent suction to keep up with this constant debris movement.
Infinity pools are demanding. The robot needs to maintain strong suction throughout the entire cleaning cycle without power drops. This is where corded robots with commercial-grade motors have an absolute advantage. Battery-powered robots can't deliver the consistent power an infinity pool demands—suction drops as the battery drains, exactly when you need it most near the overflow edge.


Infinity pools often have complex geometries—the vanishing edge, varying depths, slopes near the overflow, and sometimes curved or irregular shapes. Random-pattern robots can't handle this complexity. They get stuck near the vanishing edge, miss areas due to the unusual layout, and waste cycle time bouncing between surfaces without a plan. Smart navigation maps the pool's unique geometry and creates efficient cleaning routes that account for every surface.
SmartNav™ 3.0 with gyroscopic stability is the ideal navigation system for infinity pools. The gyroscopic component maintains the robot's orientation on slopes near the vanishing edge, while the mapping system ensures systematic coverage of the complex layout. The robot knows where the overflow edge is and navigates accordingly—cleaning effectively without risking getting caught in the overflow.
Infinity pools have extensive surface area that needs cleaning—floor, walls, and the waterline on the non-vanishing sides. The water overflow creates organic buildup near the edge that needs regular attention. Full-coverage robots that clean every surface in a single cycle are essential for maintaining the pristine appearance that infinity pool owners expect.
The area near the vanishing edge accumulates debris faster than the rest of the pool due to the constant water flow toward the overflow. A robot with smart navigation can prioritize this area, providing extra passes near the edge while still maintaining complete coverage of the rest of the pool. App-controlled spot cleaning is particularly valuable for targeting the edge zone between full cleaning cycles.


Infinity pools demand premium motor power. The slopes near the vanishing edge require strong climbing ability, the constant debris flow needs powerful suction, and the complex geometry means the robot's motors are working harder than in a standard pool. Commercial-grade dual and triple motor systems deliver the sustained power that infinity pools require—strong wall climbing, consistent suction, and the endurance to complete full cleaning cycles in demanding conditions.
Infinity pools work robots harder than standard pools. The increased surface area, constant debris, and complex navigation put more wear on motors and components. Commercial-grade motors and ProLine™ build quality are designed for exactly this kind of demanding use—delivering longer operational life and consistent performance even under the elevated workload of an infinity pool.
App control is particularly valuable for infinity pool owners. The vanishing edge area accumulates debris between full cleaning cycles, and the ability to send the robot directly to that zone for a quick spot clean keeps the pool looking pristine. Instead of running a full 2+ hour cycle, you can target the edge area in minutes from your phone.
The remote drive feature available on the Dolphin Sigma lets you manually control the robot from your phone, directing it to specific problem areas. For infinity pools, this means you can guide the robot along the edge area, around slopes, or to any zone that needs extra attention—giving you precise control over cleaning in the most demanding pool design.

Yes, but only premium robots with smart navigation and commercial-grade motors. Budget and cordless robots fail in infinity pools due to the complex geometry, constant debris movement, and higher power demands. The Dolphin Premier and Dolphin Sigma are designed for this level of demand.
No. Smart navigation systems map the pool including the vanishing edge and navigate accordingly. The robot cleans near the edge without going over it. The vanishing edge's design (water overflowing into a catch basin) doesn't create a physical drop that would cause a properly navigating robot to fall over.
Infinity pools have higher demands: constant debris movement toward the edge, complex geometry with slopes, more surface area, and harder working conditions. Budget robots lack the motor power, navigation intelligence, and build durability to maintain performance in these conditions.
The Dolphin Premier is the best overall choice with commercial-grade triple motors and oversized debris capacity. The Dolphin Sigma is the best premium choice with SmartNav™ 3.0, app control, and remote drive for targeted edge cleaning.
Daily. The constant water overflow moves debris continuously, so daily automated cycles prevent accumulation. Use the programmable weekly timer to automate daily cleaning without manual intervention.

Scrubs the tide line where oils and scum collect — the dirtiest part of the pool. A must for inground pools.

Partial wall cleaning. These models don't reach the waterline, but they clean far more than floor-only robots.

Program the power supply once and the robot cleans on schedule — every day, every other day, or every third day.

The cable spins freely as the robot turns, so it covers the whole pool without knotting up.

Pleated ultra-fine filters that trap silt, pollen and algae a standard mesh filter lets through.

Premier's exclusive filter set: fine filter, NanoFilter™, oversized leaf bag and a disposable bag option.

Start, steer, schedule and read cleaning stats from your phone over Wi-Fi or Bluetooth.

Gyroscopic sensors map the pool so the robot cleans methodically instead of bouncing at random.
