Kit de puerta de succión Maytronics Dolphin Supreme M5 Bio - 9991078-ASSY

Maytronics Dolphin Supreme M5 Bio suction door kit

This is the genuine Maytronics replacement suction door kit for the Dolphin Supreme M5 Bio PVC robotic pool cleaner. The suction door is the hinged access panel on the robot’s filter chamber that seals the internal filtration cavity during operation and opens from the top for quick debris emptying and filter maintenance.

Function and role in the filtration system

The Dolphin Supreme M5 Bio PVC features a top-access filter chamber designed for uncomplicated cleaning and emptying of filter elements. The suction door forms a critical seal that directs water flow through the robot’s internal filtration path, supporting the machine’s three-level filtration system (50/100/200 microns). A compromised or broken suction door disrupts this seal, reducing suction efficiency and allowing debris to bypass the filter.

Compatibilidad

This suction door kit is specifically designed for the Maytronics Dolphin Supreme M5 Bio PVC robotic pool cleaner — a specialist robot built for bio pools and natural swimming ponds up to 15 m in length. The Bio PVC variant uses PVC-compatible materials suited to the irregular, slippery surfaces typical of natural pool environments. Do not fit this kit to non-Bio Supreme M5 variants without confirming part cross-compatibility with Maytronics.

Síntomas que indican que es necesario un reemplazo

Replace the suction door kit if you observe: the filter alarm triggering more frequently than usual despite a clean filter; visible cracking, warping, or a broken hinge or latch on the door; water bypassing the filter chamber; or noticeably reduced suction and debris pick-up during a cleaning cycle. The Supreme M5 Bio features an integrated alarm for obstructed or improperly sealed filters, and a faulty door can trigger false alerts.

Why fit a genuine Maytronics part

The Dolphin Supreme M5 Bio PVC operates across demanding natural pool conditions — stony bottoms, irregular surfaces, and biological debris loads. Genuine Maytronics parts are manufactured to exact tolerances to maintain the watertight seal required for the robot’s internal filtration modes and external suction port. Aftermarket doors may not replicate the precise clip geometry or hinge tension of the OEM assembly, leading to premature seal failure and reduced cleaning performance.
