This is the complete drive motor unit (DB \u2014 Diagnostic Basic) for the Maytronics Dolphin Supreme M3, Swash, Orion and related floor-cleaning robots. Running on 230 V AC through a DC power supply, it provides the traction and drive that moves the robot across the pool floor for a full 3-hour cleaning cycle. When this unit fails, the robot stops moving or loses drive on one or both tracks entirely.<\/p>\n
The motor unit is the heart of the Dolphin’s drive system. It converts the low-voltage DC signal from the power supply into the mechanical rotation that turns the robot’s wheels or tracks. Without a functioning motor unit the robot sits motionless regardless of what the power supply or control board outputs. This assembly ships pre-built and ready to drop directly into the chassis.<\/p>\n
This unit fits Dolphin floor-cleaning robots in the DB (Diagnostic Basic) family operating on a 3-hour cycle: Dolphin Supreme M3 (Supreme 3), Dolphin Swash, Dolphin Orion, Dolphin X Force 10, Dolphin Swell, and Dolphin Battista Junior. It does not fit wall-climbing variants or models requiring a different motor family. The parent product in this listing is the Dolphin EasyKleen \u2014 confirm your serial-number plate before ordering if you are replacing from an EasyKleen chassis.<\/p>\n
The clearest sign is a robot that powers on \u2014 PSU LED is green, cable is live \u2014 but does not move, or pulls consistently to one side. You may also hear the motor attempting to start (a brief hum or click) before cutting out. A seized or water-ingressed motor unit will sometimes trip a thermal cutoff on the PSU. If the robot fails all motion only underwater and runs briefly in air, the internal immersion sensor is intact but the motor windings or gearbox have failed.<\/p>\n
Motor units are among the most commonly cloned Dolphin components. Aftermarket units frequently use undersized windings and inferior shaft seals, leading to premature water ingress and early failure. This is an OEM Maytronics assembly \u2014 same tolerances, same immersion-rated seals, and the same internal sensor that prevents dry-running damage. A counterfeit unit that fails in-warranty will not be covered by Maytronics service centres.<\/p>","protected":false},"excerpt":{"rendered":"
