Maytronics Dolphin C6 CB

Maytronics Dolphin C6 CB exploded view & spare parts

The Maytronics Dolphin C6 CB is a heavy-duty commercial robotic pool cleaner built to keep large pools spotless with minimal manual effort. Engineered with dual drive motors, CleverClean™ navigation and multi-layer filtration, this robot scrubs the floor, walls and waterline on every run. Like all mechanical equipment used in demanding environments, its components wear over time — and having fast access to the right spare part is the key to keeping downtime short. This exploded-view diagram page lists every numbered component of the Dolphin C6 CB so you can identify, order and fit the exact part you need, quickly and with confidence.

How to use the numbered diagram to find your part

Every component in the exploded-view illustration carries a unique reference number that maps directly to the part listings on this page. Start by locating the area of the robot that needs attention — for example, the drive train, filtration chamber or power unit — then match the relevant number in the diagram to the corresponding product below. This one-to-one system removes all guesswork: you will always order the part that was designed for your exact C6 CB configuration, not a generic equivalent that may not fit. If you are unsure which section of the diagram to look at, use the category headings below as a guide to the main assemblies.

Main replaceable parts on the Dolphin C6 CB

The C6 CB is built around several key assemblies, each of which can be serviced individually. The rubber tracks provide the grip and traction that allow the robot to climb walls and navigate slopes — without them the drive system cannot function effectively. Paired with the tracks are the scrubbing brushes, which create the mechanical contact needed to dislodge dirt, algae and debris from pool surfaces. The filter panels and filter bags form the robot’s multi-layer filtration system, capturing everything from fine dust particles to coarse leaf matter in a single pass. At the heart of the hydraulic circuit sits the impeller, which generates the suction that draws water and debris through the filters, while the motor unit powers both the drive and the pump. Connecting the robot to its power source is the anti-tangle floating cable, equipped with Dolphin’s swivel technology, and the power supply (transformer unit) converts mains electricity into the safe low-voltage current the robot requires. Finally, the handle and the matching caddy make lifting and transporting this commercial-grade robot straightforward, even when it is wet and heavy after a cleaning cycle.

Common wear items and when to replace them

Certain parts of the Dolphin C6 CB experience more stress than others and will need periodic replacement as part of routine maintenance. The tracks are among the first components to show wear: look for cracking, stretching or reduced grip on walls as your signal to replace them. The brushes wear down with every cleaning session; once the bristles are visibly shortened or flattened they can no longer scrub effectively, leaving algae and biofilm on pool surfaces. Filter panels and bags should be rinsed after every cycle and inspected regularly — tears, holes or persistent clogging that does not clear with rinsing indicate it is time for a new set. The impeller can become cracked or clogged by sharp debris, leading to a noticeable drop in suction; if cleaning the impeller does not restore flow, replacement is the next step. The floating cable is subject to UV exposure, pool chemicals and repeated flexing, so any cracking of the outer sheath or loss of buoyancy means it should be swapped before an internal fault develops. The power supply is the electronic brain of the system; if the robot fails to start or behaves erratically after ruling out other causes, the power supply unit is the component to test and, if necessary, replace.

Handle and caddy — often overlooked, always essential

The Dolphin C6 CB is a substantial commercial machine, and its handle is the primary lifting point every time the robot is retrieved from the pool. A cracked or loose handle is both a safety risk and a frustration, and it is one of the more straightforward parts to swap using the diagram. The matching caddy (cart/trolley) is equally important in a commercial setting: it keeps the robot, cable and power supply organised, protects the unit between cycles and makes it easy to move the equipment around the pool deck. Replacement caddy parts — including wheels, axles and frame components — are listed individually in the diagram so you can repair rather than replace the entire trolley.

Why genuine Maytronics parts matter

Fitting genuine Maytronics spare parts to your Dolphin C6 CB is not simply a brand preference — it is a practical decision that protects your investment. Genuine parts are manufactured to the same tolerances as the originals, so tracks seat correctly on drive sprockets, brushes align flush with pool surfaces, and filter panels seal properly within their housing without gaps that would allow debris to bypass the filtration stage. Third-party components may appear similar but can accelerate wear on adjoining parts, reduce cleaning performance and, in the case of electrical components such as the power supply, introduce safety risks. All genuine Dolphin parts sold on poolparthub.com are sourced directly from Maytronics, ensuring full compatibility with your C6 CB and giving you the assurance that your robot will perform exactly as it was designed to.
