Maytronics Dolphin Active Classic CB

Maytronics Dolphin Active Classic CB exploded view & spare parts

The Maytronics Dolphin Active Classic CB is a reliable in-ground robotic pool cleaner that keeps your pool spotless with intelligent CleverClean™ navigation and an anti-tangle swivel floating cable. Like every Dolphin robot, it is built from a well-defined set of components — each one replaceable with a genuine Maytronics spare part. This exploded-view diagram page gives you a numbered breakdown of every part in the Active Classic CB so you can identify exactly what you need and order with confidence from poolparthub.com.

How to use the numbered diagram to find the right part

The exploded-view diagram above shows the Dolphin Active Classic CB disassembled into its individual components, with every part assigned a unique reference number. To find the spare part you need, locate the relevant area of the robot — for example, the drive train, the filter basket, or the power supply — and note the reference number printed next to it. Match that number to the corresponding entry in the parts list below the diagram, where you will find the official Maytronics part name, part number, and an add-to-cart button. If you are unsure which part has failed, cross-reference with the component descriptions in the sections below before ordering.

Tracks, brushes and the drive system

The rubber tracks and scrubbing brushes are the Active Classic CB’s main contact points with your pool surface. The tracks grip the floor and walls, propelling the robot through each cleaning cycle, while the brushes agitate algae, biofilm, and fine debris loose so it can be drawn up into the filter. Because they are in constant contact with water, chemicals, and abrasive pool surfaces, both components experience steady wear. Check the tracks for signs of stretching, cracking, or slipping, and inspect the brush bristles for flattening or uneven wear. When the robot begins to struggle with traction or leaves visible debris behind after a full cycle, it is usually time to fit a fresh set of genuine Maytronics replacement tracks and brushes.

Filter panels, filter bags and the impeller

The Dolphin Active Classic CB captures dirt through a top-access filter basket that accepts both fine filter panels and ultra-fine filter bags, making it easy to switch filtration grade depending on the season and debris level. Maytronics recommends cleaning the filter basket after every single cleaning cycle — rinse the panels or bag with a garden hose while they are still damp, as dried debris is harder to remove. Over time, even well-maintained filter media develops micro-tears or loses its rigidity, reducing suction efficiency. Replace filter panels or bags when you notice the water returning to the pool is cloudy, or when the basket no longer seals firmly in its housing. The impeller sits just behind the filter basket and draws water through the filtration path; if it becomes jammed with hair, string, or debris, clean it according to the steps in your manual. A damaged or worn impeller should be replaced promptly, as a restricted flow puts extra strain on the motor unit.

Motor unit, floating cable and power supply

The motor unit is the heart of the Active Classic CB, driving both the pump and the drive wheels. It is a sealed, low-voltage assembly designed for long service life, but it can be damaged by prolonged exposure to unbalanced water chemistry or by running the robot outside the pool without water cooling. The floating cable connects the robot to the power supply unit (PSU) and features an anti-tangle swivel to keep it from kinking during operation. Always make sure the floating cable is free of obstacles before starting a cleaning cycle, and allow it to dry fully — spread flat — before storing. The PSU converts mains voltage to the safe low voltage used by the robot; never operate the Active Classic CB with a damaged or third-party power supply. Both the cable and the PSU are safety-critical components, so always replace them with certified genuine Maytronics parts.

Handle, caddy and everyday wear items

The handle is moulded into the top of the Active Classic CB’s body and is the correct lifting point when retrieving the robot from the pool — always pull the robot to the poolside using the floating cable first, then lift it clear of the water by the handle to protect your back and the internal components. The storage caddy keeps the robot, cable, and power supply neatly organised between sessions, protecting the unit from UV damage and accidental knocks. Caddy brackets and the handle itself can crack over years of use, especially in climates with strong sunlight, and both are straightforward parts to replace. Keeping a spare handle bracket and a set of tracks and brushes on hand means you can carry out routine maintenance quickly at the start of each season without waiting for parts to arrive.

Why genuine Maytronics parts matter

Every spare part listed on this page is an official Maytronics OEM component, engineered to the exact tolerances of the Dolphin Active Classic CB. Genuine parts are backed by a Maytronics limited warranty and are guaranteed to be compatible straight out of the box — no trimming, adapting, or risk of voiding your robot’s warranty. Third-party imitations may appear similar but are frequently made from lower-grade materials that degrade faster in chlorinated or salt water, leading to premature failure and potentially causing collateral damage to the motor unit or PSU. Choosing genuine Dolphin spare parts from poolparthub.com protects your investment, maintains optimal cleaning performance, and keeps your robot running season after season.
