It has been far too common for a company to promise an upgraded version of its current product with refinements in performance and new features. Disappointing iteration unfortunately follows quite often, too.
Your favorite features are no longer supported and there are too many unnecessary bells and whistles in the updated version. In the Dolphin DX4S, however, you have none of those.
Main Features of Dolphin DX4S Automatic Robotic Cleaner
Intended to be the better upgraded more powerful version of the popular DX3S, Dolphin still gives all major features in the DX4S. An advanced IntelliScan Technology remains present to analyze pool surface and determine the best possible cleaning routes.
It may take a little bit longer for the robot to clean the entire surface at first-time cleaning, but the analytic software allows for better recognition ability afterwards. Faster cleaning is expected after several cycles.
The DX4S comes with all the core Dolphin robotic pool cleaner features including 60 feet swivel cable, dual bottom-mounted quick-release filter cartridge, suction rate of more than 4,000 gallons per hour, 2.5 hour default cleaning cycle, and weekly timer.
Maytronics, the company behind Dolphin Pool Cleaners, has managed to improve some of those core functionalities. The weekly timer is now more effective thanks to full filter indicator.
It means you can basically leave the robot for as long as you want in the pool and take it out only when the indicator turns on. Also, the optional remote control opens access to shorter 1-hour cleaning cycle.
The real highlight in the Dolphin DX4S is its ability to clean floors, walls, coves, and even tile lines. It actually makes no sense if a robotic pool cleaner only scrubs floor, and you must do the rest of the jobs manually. This robot is packaged with a Pro Caddy at no additional cost.
On the plus side, the Dolphin DX4S is an honest product that delivers actual improvements over its predecessor. Newly added features make the robot easier to use particularly with full filter indicator and the optional remote control.
Pretty much everything else is still the same, and in this case, that is a good thing. IntelliScan Technology planted to this robot is also an updated version for better intelligence and accuracy.
A minor drawback is that the package does not include the remote control. If you want to use the 1-hour cleaning cycle, you must purchase the remote separately. Considering this is a minor improvement, it seems silly that the company tries to make you purchase two new products, so you can use less necessary upgrade. Read more reviews here.
