Dolphin C3 vs Dolphin Premier Comparison

Build Quality and Look

The dolphin pool cleaners are known to provide efficient cleaning robots. As both cleaners are from the same brand let us start by comparing the different looks of both the cleaners. the Dolphin C3 comes with a classic combination of white and black colour. The shiny bright white covers the entire body of the cleaner and the black is used for the detailing. The Dolphin premier looks very different in comparison to C3, the premier comes in the basic and elegant colour combination of blue and grey colour. The entire body is covered with grey colour and few areas are provided with refreshing blue colour detailing. When looking at the dimensions, the C3 has 23.6 x 20 x 19.5 inches and weighs 24.6 pounds. The dimensions of the premier are 23.5 x 19.5 x 14 inches and weigh 22 pounds.

Both the cleaners are lightly built compared to the competing models. Both have similar look with the handle at the top, but the material of C3 gives it a much more elegant look. Both the cleaners are equipped with tracks instead of separate tires. The tracks provide the cleaners with the extra required grip needed to climb the walls of the pool. The tracks also allow the smooth movement of the cleaner while cleaning. The length of the cable is also the same, both have 60 feet cable which means both cleaners can cover similar sized pools. There hardly lies any difference in both the cleaners in terms of the look, the elegant and futuristic look of C3 is all that makes it a bit more eye-catching rest of the features are similar.

Cleaning Technique

One thing that dolphin pool cleaners never let you down on is the cleaning performance of its pool cleaners. The Premier works on a dual scrubbing brush system. There are two brushes at the front and two at the back to reach corners and angles. The scrubbing brushes are able to loosen bio-film and algae from the surface of the pool before sucking the dirt into the filter. The premier can cover the pool surface of gunite/plaster, vinyl, and fiberglass. The C3 includes two similar scrubbers which also have blades attached to them. The blades can easily scrub off any dirt or algae from the bottom of the pool. The suction inlet of the C3 can remove 4000 gallons per hour, however, in this case, the premier is slightly better as it can remove 4500 gallons every hour. Both the pool cleaners cover the area of pool surface, walls, and the waterline effectively. In terms of cleaning performance, one cannot be disappointed with either of these cleaners. Although they slightly differ in terms of technique both still do their job commendably.

Navigation System

As technology is advancing at the speed of light nowadays, pool cleaners are not left behind. The majority of the pool cleaners come with an in-built navigation system, which is able to control their movement and doesn’t let them wander off aimlessly. The C3 and Premier both come with different navigation systems. The C3 is equipped with CleverClean navigation technology. The CleverClean technology is designed to swiftly scan the swimming pool and gather information regarding the measurements and shape of the pool. With this, the cleaner is sent to a timesaving route by covering the walls and the side area of the pool. It also helps in identifying and avoiding obstacles.

The cleaner is also able to create a new route with every new cleaning cycle. The special algorithm used by the software ensures that the cable cord remains tangle-free. The premier on the other hand uses the SmartNav navigation system. The SmartNav system just requires a few seconds of immersion in the water to be able to scan the area and then plans the area that needs to be cleaned by avoiding obstacles in its way. This navigation system avoids the cleaner to go to the same place which has been already cleaned. None of the cleaners will wander in an indecisive manner in your pool. The navigation systems however different are incredible in their work.
