Product details

The Maytronics 3884073-ASSY is the wheel bearing used across a long list of Dolphin robotic pool cleaners, from the Nautilus and Triton through the M200, M400 and Supreme series. It is the genuine Maytronics part.

Why it fails

The bearing sits in the wheel hub, underwater, in the dirtiest part of the pool. Fine sand works past the seal and grinds away at it, and the wheel that used to spin with a flick of a finger starts to feel notchy and then locks up. The cleaner keeps trying to drive, so what the owner sees is a machine that pulls to one side, misses whole sections of floor or gives up halfway up the wall.

Checking and replacing

Take the wheel off and spin the bearing by hand. Any roughness, drag or side to side play means it is done. Bearings on one cleaner have all logged the same hours, so if one has failed it is worth checking the rest while the machine is apart.

Fitment

Dolphin Nautilus Plus, Nautilus, Triton, Triton Plus, M200, M400, C3 CB, C4 CB, Discovery, Saturn, Edge, Endeavor, Supreme M3, Supreme M4 and Supreme M5.

Questions and answers

What people ask about this product, answered by our pool techs.

Which Dolphin models does it fit?
Nautilus Plus, Nautilus, Triton, Triton Plus, M200, M400, C3 CB, C4 CB, Discovery, Saturn, Edge, Endeavor, Supreme M3, Supreme M4 and Supreme M5.
How do I know a bearing has gone?
The cleaner drags to one side, climbs badly or stalls, and a wheel that should spin freely by hand feels notchy or stiff. Pull the wheel off and the bearing will usually be full of grit.
How many do I need?
Count the wheels on your cleaner and check each bearing. Bearings on the same machine have all done the same hours, so most people replace more than one at a time.
Is it a genuine Maytronics part?
Yes. It is Maytronics part number 3884073-ASSY.
