Hayward AquaVac 650 (AV650 WiFi) exploded view & spare parts

This page covers the complete exploded-view diagram and bill of materials for the Hayward AquaVac 650 WiFi robotic pool cleaner, sold through Bosta under part references 7029617 and 7025399. The diagram breaks the AV650 down into every major assembly and sub-component — from the power supply and motor box through to the cyclone canister, brushes, wheels, and separation filters. Whether you are a pool owner carrying out routine brush or wheel replacement, or a technician diagnosing a drive or suction fault, you will be able to identify the exact part you need within minutes. All stocked parts carry a Bosta SKU that can be added directly to your basket.

How to use the numbered diagram to find your part

Every numbered call-out on the diagram corresponds directly to a row in the parts list below; the position number printed beside a component in the drawing is the same number shown in the leftmost column of the table. Start by locating the area of the cleaner where the fault or wear has occurred — for example, the drive base, the cyclone canister, or the power supply section — then find the relevant call-out number on the drawing. Cross-reference that number to the table to confirm the description and, where available, the Bosta SKU. Bear in mind that some position numbers appear in more than one location on the drawing: this is normal for shared fasteners, seals, or trim pieces that are used in several spots on the same assembly. Pay close attention to lettered suffixes — positions 21a and 21b, for instance, are two different brushes for the same location, and positions 25a and 25b are two different separation filters with different filtration ratings. Ordering the wrong variant will mean the part does not function correctly even if it fits the aperture. Where a SKU column is blank, the component shown is a cosmetic or structural shell part that is currently supplied as part of a larger assembly rather than individually; in those cases, contact our team for guidance. Finally, note that the last row of the BOM (position reference 7029617 / 7025399) is the parent unit identifier for the HAYWARD AQUAVAC 650, not an orderable line item.

Main replaceable assemblies on the AquaVac 650

The power and control section centres on the Power Supply AV650 WiFi (position 2, SKU 7034434) and the associated Power Supply unit (position 11, SKU 7034437); these are distinct parts, so confirm which unit has failed before ordering. The floating power cord assembly (position 3, SKU 7034435) connects the supply to the cleaner in the water and is a common wear item. At the heart of the cleaner’s filterless suction system is the Cyclone Assembly Kit (position 7, SKU 7034436), which houses the cyclonic separation technology that maintains consistent suction power throughout the cleaning cycle. The canister section also includes the Cyclone Check Valve Assembly (position 4) and the Cyclone Cosmetic Top AV650 in blue (position 5), along with the Canister Twist Lock (position 6), which secures the debris canister to the body. The Motor Box Assembly AV650 WiFi (position 15, SKU 7034441) contains the drive electronics and is the primary assembly to address when the cleaner loses motive power entirely. The Pump Motor Shaft Coupling (position 14, SKU 7034440) transfers drive between the motor and the pump and is a relatively accessible wear component. The Gear Box Assembly (position 22, SKU 7034445) governs the six-roller HexaDrive system that allows the cleaner to navigate pool floors and climb walls. The vacuum inlet is split between the Vacuum Inlet Top Assembly (position 12, SKU 7034438 in black or 7034439 in grey) and the Vacuum Inlet Bottom (position 19, SKU 7034442), both of which should be inspected when suction performance drops. Cleaning contact with the pool surface is maintained through the Middle Short Brush Assembly in dark grey (position 20, SKU 7034443) and the long brush options at position 21 (see variants below). The wheel system consists of the Wheel Assembly Kit in blue (position 23, SKU 7034446) and the Wheel Tread Kit in metallic blue (position 24, SKU 7034447); treads typically wear before the wheel assembly itself and can be replaced independently.

Choosing between variants and pack sizes

Position 21 has two distinct variants: 21a is the PVC brush long exterior in grey (SKU 7034444), a firm-bristle brush suited to plaster and concrete pool surfaces, while 21b is the long grey foam brush (SKU 7029616), which is better suited to smoother vinyl or tiled surfaces. Fitting the wrong brush type will not damage the cleaner, but it may reduce scrubbing effectiveness on your particular pool surface, so select the variant that matches your pool finish. Position 12 similarly comes in two colour variants — black (SKU 7034438) and grey (SKU 7034439) — which correspond to different shell colour configurations of the AV650; the functional specification is identical, but only the colour-matched part will align correctly with the surrounding shell panels at position 17. Position 25 offers two separation filter ratings: 25a is the 300 micron filter (SKU 7034448) for general debris, and 25b is the finer 125 micron filter (SKU 7034449) for pools with fine silt or small particulate matter. Choosing the correct filtration grade for your pool conditions will maintain the cleaner’s cyclonic suction performance over the length of a cleaning cycle.
