Owning a swimming pool is great, especially in the high summer temperatures because you can easily jump in for a refreshing dip when things get too hot. However, maintenance of the swimming pool is where things get a bit tough for most people.
From ensuring that the pumps and mechanical circulation and filtration systems are working as they should to cleaning of the walls and floor, a swimming pool requires a significant time investment if you want to keep it looking good and working great.
Fortunately, technology has made this process easy so that swimming pool owners can enjoy the fun and convenience of having a swimming pool at home without having to spend too much time on maintenance.
One such innovation is the pool cleaner that will automatically move around the swimming pool floor and walls removing any dirt or debris present to leave you with a swimming pool that looks clean and inviting.
Let’s start by taking a quick look at the different types of pool cleaners available on the market today.
Types of Automatic Pool Cleaners
There are three broad groups of automatic pool cleaners. The main difference between these three groups is the method used to clean your swimming pool.
Suction-side Pool Cleaners
Suction-side pool cleaner’s work by attaching to the vacuum side of the swimming pool. The vacuum is then passed through the cleaner where it is used to suck in the dirt and debris and also to propel the cleaner around the swimming pool.
This type of pool cleaner is usually very affordable to buy, but it puts pressure on your existing filtration system because all the collected dirt and debris will go through the pool’s filtration system. It could also increase the pool’s running costs because you will have to keep the circulation system running for the pool cleaner to function.
Pressure-side Pool Cleaners
On the other hand, pressure-side pool cleaners use pressure from the water as it is pumped back into the pool from the pool’s filtration and circulation system. These cleaners use the venturi effect created by water as it passes through a narrow throat in the filter to create a suction that lifts dirt and debris from the pool floor and walls. This pressure also powers the wheels to help the cleaner as it moves around your home.
Unlike suction-side pool cleaners, these pool cleaners usually come with their filter bags, so the impact of the cleaner on your filtration system is relatively low. However, they will also need pressure from your circulation system so you will have to keep it running while cleaning is in progress.
Robotic Pool Cleaners
Finally, there are robotic pool cleaners that are intelligent self-powered devices that move around your swimming pool automatically collecting dirt and debris. Some will even filter some of the water in the process of cleaning to reduce the pressure on your filtration system.
These pool cleaners don’t need any input from your pool’s circulation system so you can leave it off as they work. They come with pumps and filters so they will produce the same results regardless of how weak or strong your swimming pool pump and filtration system is. They are however more complex and as a result more expensive than the other two types of automatic pool cleaners.

Dolphin C Series for Commercial Use
Let’s now take a look at the tougher commercial models. In Dolphin’s C series, there are currently four models. These are the C3, the C4, the C5, and the C6 Plus pool cleaners. The C3 is by far the most popular in the series because it is tough, affordable and durable enough to withstand commercial use.
When it comes to size, none of these robots are similar. The C3 can clean pools of up to 50 feet, the C4 takes it a notch higher by cleaning up to 68 feet pools, the C5 can handle up to 88-foot pools and the C6 can handle the largest pools up to 121 feet.
All four models will clean the floor, walls, and waterline and they come with both fine and ultra-fine filters.

The filters on the C3 and C4 are the easy to use top-load filters while the C5 and C6 Plus come with the more difficult to handle bottom-load bags.
Scrubbing brushes are a bit different across the series because the C3 and C5 come with two standard brushes, the C6 Plus comes with four standard brushes while the c4 comes with one active brush and two standard brushes.
When it comes to cleaning cycles, the C3 comes with two cleaning cycles: a quick 1-hour cycle and a longer 2.5-hour standard cycle. The C4 also comes with the two cycles in the C3 and an Enhanced 3.5-hour cycle. Finally, the C5 and C6 Plus come with a 4-hour quick cycle, a 6-hour standard cycle, and an 8-hour enhanced cycle.

Dolphin H Series for Commercial Use
The H series has three options: the H50, the H80, and the H120. These three models are tough and will withstand the tough requirements of commercial use. Like it is in the C series, the H50, which happens to be the cheapest one, is the most popular of the three.

When it comes to cleaning cycles, the H50 is the fastest and the simplest with a cleaning cycle of 3-hours. The other two have more options. You can choose the quick 4-hour cycle, the standard 6-hour option or the enhanced 8-hour option.
They all come with caddies that make it easy to transport the machines to whichever pool you’d like to clean. Once they are inside the pool, CleverClean navigation technology kicks in to ensure that the pool cleaner quickly scans the pool to come up with the most efficient cleaning pattern.
Now that we know what is available from some of the most popular pool cleaners from Dolphin, let’s identify some of the important things that you should keep in mind as you shop for a pool cleaner for your swimming pool.
We have looked at several different robot pool cleaners from Dolphin. Although this list contains the most popular models in all categories, it is not a conclusive list of all the robot pool cleaners made by Maytronics under the Dolphin brand.
It gets worse: the market has other models made by other manufacturers each claiming to the best in its category. This means that as a buyer, you will be bombarded by hundreds of models each claiming to be the best for you.
