Maytronics, the manufacturer of the Dolphin range of automatic pool cleaners have introduced two new cleaners for 2018 to replace the Dolphin Magic and the Dolphin Dynamic Plus. The new pool cleaners are called the M400 and the M500. Externally they look exactly the same but internally there are some significant differences.

First we’ll look at how the M400, full name the Dolphin Supreme M400, has improved upon the Dolphin Magic and then we’ll look at how the M500 differs from the M400.

The Dolphin Supreme M400 and M500 look alike but differ internally


The most obvious change is in the colour from the orange case of the Dolphin Magic to a more understated blue for the M400 but the Dolphin Dynamic Plus was blue before so now it is not so easy to tell them apart.


Extra Power

Maytronics have introduced a third roller brush to the new models. This is to give extra scrubbing power to get algea of the floor of the pool and also means that the problem that some cleaners have of getting stuck on a raised main drain is eliminated.

The Dolphin Magic had a bag to collect the debris in and so could not pick up the fine dust in the way that the Tiger Shark can. That has changed with the M400 because it now has paper filters like the Tiger Shark in two versions, fine and ultrafine but it can also have a filter bag if you prefer. Bags are easier to clean but paper filter can collect finer dirt.

When you want to take the bag or filter out to clean it on all other automatic swimming pool cleaners you have turn them on their side because the filters come out from underneath the machine. On the M4 the filters come out from the top, quite a handy little improvement.

Like all top end automatic swimming pool cleaners the Dolphin Supreme M400 will climb the walls and clean the scumline by default.


Wireless Remote Control

The Dolphin Supreme M500 differs from the M400 mainly because it has a wireless remote control. If the cleaner has missed a bit you can send it in to the area and make it clean up. In rectangular pools this is rarely necessary but is a very useful feature if you have free-form or kidney shaped swimming pool. As well as this the M500 tells you when the filter needs cleaning by means of a light on the transformer and the wall climbing mode can be switched off if required.

In the league table of automatic swimming pool cleaners the Dolphin Supreme M4 and M5 are clearly on top. There is no better pool cleaner but they are not cheap. At £1,325.00 and £1,895.00 they are the most expensive pool cleaners but they are definitely the best.
