Maytronics - Dolphin EasyKleen internal float - 6250931

Maytronics Dolphin EasyKleen internal float

This is the genuine OEM internal float for the Maytronics Dolphin EasyKleen robotic pool cleaner, also cross-referenced across the Dolphin Supreme M3, Neptune, DX3, DX3s, and Atlantis platforms. Mounted inside the robot’s body, it provides the buoyancy balance that keeps the cleaner tracking correctly against the pool floor and walls during a cleaning cycle.

What this internal float does in the Dolphin

The internal float is a sealed buoyancy insert housed within the robot’s shell. It counteracts the weight of the motor and drivetrain, setting the robot’s neutral buoyancy point so that the cleaning brushes and suction inlet maintain the correct contact pressure against pool surfaces. When the float is cracked, waterlogged, or missing, the robot becomes bow-heavy, loses wall-climbing ability, and may stall on the pool floor.

Which Dolphin models it fits

Part number 6250931 is the confirmed internal float for the Dolphin EasyKleen (listed parent product) and is cross-referenced to the Dolphin Supreme M3, Neptune, DX3, and DX3s. Verify your model number on the label inside the filter-access hatch before ordering — do not fit to models outside this range.

Signs it needs replacing

The cleaner sinks nose-first or sits heavily on the pool floor rather than rising freely when you lift the cable. You may also see the robot failing to climb walls or completing only flat-floor cycles. A visual inspection of the float itself will show cracking, deformation, or water ingress — any of these means replacement is overdue.

How to install it

Open the top cover of the robot to access the internal cavity. Remove the old float — it typically clips or slots into a moulded recess in the shell — and press the replacement into position until it seats fully. No adhesive or tools are required. Reassemble the cover, lower the robot into water, and confirm it floats level before starting a cycle.
