Top 4 Best Robotic Pool Cleaners for Commercial Use

Dolphin C3

Being the most dominant force in the industry, our list is full of Maytronics products. First off is the Dolphin C3, a sleek, compact robotic pool cleaner that is designed to clean inground pools of up to 50 feet in length.

The Dolphin C3 uses CleverClean technology to scan its surroundings and create the most efficient cleaning route for maximum coverage per cycle. Dual standard brushrolls work quickly at scrubbing the slimiest algae off of pool lining and waterline to give your pool the crystal-clarity after 2.5 hours of work.

Dolphin C4

Next is the Dolphin C4, a robot with two standard brushes and an active brush that serves to pull in all pool debris into its suction inlet. It also relies on CleverClean software to navigate the floors and walls of your pool to remove as much debris as possible in p to 3.5 hours of nonstop work.

The twin top-loaded filters separate large from fine debris in order to maintain more than 1,000 GPM of water recirculation. Apart from the standard controller module, you also get a handy remote control for quick controls from a distance.

Dolphin C5

The Dolphin C5 is a lot like the previous two models, except that its anti-tangle swivel cord supports coverage of inground pools of up to 88 feet long. Since it covers a wider area per cycle, it spends considerably more time submerged—up to 8 hours for enhanced cleaning.

The Dolphin C5 differs from the previous two by its filtration system’s design. Instead of two top-loaded filter baskets, it uses a single bottom-load filter bag that collects all debris for quicker cleanup. Two filters of different sizes ensure that its inlet is left unclogged for longer.

Dolphin C6 Plus

Last is the Dolphin C6 Plus, a robotic pool cleaner truly made for commercial purposes seeing as how its power cord supports free, uninhibited movements in pools of up to 121 feet in length. This beast utilizes four standard brushes that scrub floors, walls, and waterlines much more efficiently than the rest.

Like the C5, The Dolphin C6 Plus allotted cleaning times range from four to eight hours to ensure perfectly clean water and pool linings in large inground pools. The width of this robot is nearly twice that of the C3 or C4, allowing it to clean a wider surface area with each pass in less time.

Why the Maytronics Dolphin Series Is the Best Choice

Maytronics has been in the robot producing game for several decades now. Their line of robotic pool cleaners is often considered to be the best of the best for several very, very good reasons.
First, they filter and circulate more than 1,000 gallons of water every minute.

Next, they come with pretty advanced navigation software that creates the most efficient route in order to cover more square feet of pool walls and floors in its allotted cleaning time. And finally, they’re simply the best in terms of performance, design, convenience, and reliability.

Important Considerations

Coverage Distance

The most important thing to take into account is whether the Dolphin robotic pool cleaner can clean your pool from end to end. You first need to measure the length of your pool and determine the longest distance, and then you can decide which of these Dolphin robotic pool cleaners will work.

A general rule of thumb is to find a robot that has a coverage distance of 10 to 20 feet more than the actual length of your pool.

Cleaning Coverage

This point refers to which surface or surfaces the robotic pool cleaner can get to. Obviously, the robot should be able to scrub the base of your pool, but can it propel itself vertically to clean the walls and waterline? All four of these Dolphins can.

Top-Load Filter Baskets vs. Bottom-Load Bags

The C3 and C4 have top-load filter baskets which are quicker and easier to access and clean compared to the bottom-load bags found in the C5 and C6 Plus. However, the bags can hold onto more pool gunk than the filter baskets so there’s less actual cleanup required.


1. What are the differences between commercial and residential robotic pool cleaners?

The main difference between commercial and residential robotic pool cleaners is the length of its cord. Home-grade robotic pool cleaners typically have a maximum reach of 50 feet, whereas commercial-use robots, as you can see on our list, can travel beyond 100 feet before the cord becomes taut.

2. Can you leave a robotic pool cleaner in the pool?

Some robotic pool cleaners should only be placed in the water to run its cleaning cycle, but the four Dolphins on our list don’t. You can leave them fully submerged for weeks at a time without the slightest indication of corrosion or damage to its internal components. However, we suggest taking it out when your pools are inoperable during the colder months.

3. How often should I run the robotic pool cleaner?

It depends on how often you use your pool and how dirty it gets. In general, running the robot once a week should suffice, although some robots have programmable schedulers that automatically commence its cleaning cycle one, twice, or three times a week. Sadly, this isn’t the case with any of these four Dolphin robotic pool cleaners.

4. How long to robotic pool cleaners last?

Robotic pool cleaners, on average, have a maximum lifespan of five years, though it’s not uncommon to get eight to ten years out of a single robot with proper care. Surfacing the robot when it’s not needed in during fall and winter can increase its lifespan significantly since they can remain completely dry when not in use.
