The complete Fluffycones hard-floor cleaner head should be isolated from its owner-removable connections before a powered-head motor, control, or whole-head failure is considered. Multidirectional Fluffycones head with four soft conical brush bars, plus a separately powered compact hair tool on equipped packages. This procedure is scoped to the PencilVac (SV50) and its cordless Dyson stick-vacuum platform.

Instructions
How to complete this repair
- Bright flashlight
- Scissors or a seam ripper for wrapped fibers
- Soft dry brush
- Clean lint-free cloth
- Power the vacuum off, disconnect its charger, and remove a detachable battery only when the exact owner guide describes that action.
- Use only owner-access points and maintenance actions documented for the exact machine code.
- Do not cut toward the brush surface, wiring, soft roller, or cleaner-head housing.
- Do not open a brush motor, gearbox, powered-head wiring channel, or sealed bearing housing.
Confirm the PencilVac configuration
PencilVac (SV50) is a bagless cordless body with a wand and Fluffycones hard-floor cleaner head. Cataloged variants include PencilVac Fluffycones. The verified owner-service profile identifies it as the Dyson PencilVac Fluffycones slim cordless platform. Match the machine code and serial label before ordering a filter, bin, wand, cleaner head, battery, or charger; a retail family name can cover incompatible hardware.
Isolate the complete powered head or tool
Follow the exact owner guide to detach the Fluffycones hard-floor cleaner head as a complete owner-removable assembly. Multidirectional Fluffycones head with four soft conical brush bars, plus a separately powered compact hair tool on equipped packages. Detach the floor tool or cleaner head from the machine before working around the brush.
Rule out a brush jam inside the head
Cut and lift away hair, thread, and fibers in small sections. Remove debris from accessible end-cap and inlet areas without prying off a sealed bearing or gear cover. Check for melted fibers, cracks, distortion, or an end that remains seized.
Check the platform-specific connection
Inspect the external electrical contacts and latches between the Fluffycones hard-floor cleaner head and the next owner-removable assembly. Contacts must be dry, clean, straight, and free of scorching. This is not a belt-replacement path.
Make one controlled brush test
Reassemble the machine completely and test the Fluffycones hard-floor cleaner head briefly on a clear, suitable surface. Stop if it stalls again, pulses, smells hot, shows an error, or makes a grinding noise.
A brush that remains stationary after debris and external connections are checked needs professional cleaner-head, drive, or control diagnosis.
