Dolphin Sigma vs. Polaris F9550

Portability Comparison

The dimensions of Dolphin Sigma are 23 x 19.5 x 13.5 inches, while Polaris 9550 has a 22 x 22 x 22-inch cubic shape.

Dolphin is significantly more lightweight than Polaris, weighing in at 35 pounds compared to Polaris’ 43.6 pounds.

Dolphin Sigma boasts a sleek white design, while Polaris 9550 is characterized by its blue color and intimidating appearance with its large side wheels.

Dolphin employs a unique brush system consisting of dual scrubbers and hyper grip tracks, unlike the solid-blade brush and aqua-Trax tires utilized by Polaris 9550.

Power Comparison

Dolphin Sigma is only compatible with Fiberglass, Gunite/plaster, Vinyl pool surfaces, and is recommended for pools measuring 50 feet in length.

In this round, the Polaris pool cleaner has an edge due to its ability to effectively clean all floor types and the capacity to clean pools up to 60 feet.

Despite both machines having a cleaning cycle of 2.5 hours, the Dolphin lacks an easy lift system found in the Polaris, making it more fatiguing to use over extended periods.

The Polaris 9550 pool cleaner utilizes a water propulsion system which enables it to effectively clean debris in hard-to-reach areas such as tight corners and under stairs. In contrast, the Dolphin Sigma’s anti-tangling swivel cable allows for unrestricted movement throughout the pool.

Both machines operate quietly, with low motor noise, ensuring that you won’t be irritated by clicking sounds like some other cleaners find it irritated like some other cleaners that produce clicking sounds.

Despite this, the Dolphin Sigma’s larger filters allow for a more efficient flow of water and a more thorough cleaning of contaminants.

Features Comparison

Both Dolphin Sigma and Polaris can set timers and have advanced navigation, but there is a key difference in how they are controlled. Dolphin Sigma can be controlled remotely through a smartphone app, while Polaris requires the use of a handheld remote, which can be less convenient. Losing or breaking the remote can cause issues with managing the Polaris robotic pool cleaner.

Lastly, the simple lift mechanism on the Polaris 9550 is a standout feature. With just the press of a button, the robot will rotate counter-clockwise and wait by the waterline for you to retrieve it. This makes it effortless to remove the device from the pool. In contrast, the Dolphin Sigma does not have this capability, making the Polaris the preferred choice for us in this comparison.
