Of the Dolphins we don't stock, the Proteus DX5i has the strongest review record — four stars across several hundred reviews. It pairs Wi-Fi scheduling with real waterline scrubbing at 17.4 lb, which is a genuinely good combination.
Waterline scrubbing done properly
Maytronics is specific here: the DX5i maintains constant grip on the wall, which is what gives the brush sustained contact with the tile band. A robot that loses traction near the top gets a fraction of a second on the waterline and leaves the grey line intact.
Scheduling
MyDolphin Plus handles recurring schedules and remote start. Set it overnight and the pool is ready in the morning without you touching anything.
Weight
17.4 lb puts it among the lightest corded robots with this feature set. That matters every single time you take it out.
Worth knowing before you buy
We don't stock the DX5i. If you'd rather buy from us, the Dolphin Quantum covers similar ground with our own support behind it — worth comparing the two.
