When a Dyson DC17 suddenly stops pulling at the wand but still cleans the floor normally, the hose is usually the reason. This gray replacement hose assembly restores that above-floor airflow, so the crevice tool, stair tool and dusting brush work the way they did when the machine was new. The hose is the flexible section that connects the machine body to the wand, and it carries the full airflow whenever the tools are in use.
Hoses on uprights of this generation typically fail by splitting at a cuff or cracking along the convolutions after repeated stretching. The result is a sudden loss of suction at the tool while the motor still sounds and runs normally, which is why so many owners chase filters and brush bars first. Replacing the hose is a far smaller job than replacing the vacuum.
Use cases
- Households whose DC17 has lost attachment suction while floor pickup is still strong
- Stair and upholstery cleaning, where the hose is stretched and released on every pass
- Pet owners running a DC17 Animal daily, where hose wear shows up fastest
- Cleaning contractors keeping a spare hose on the shelf so a machine never sits idle
- Owners of older DC17 machines who would rather repair than replace

Notes
No manufacturer figure is published for the relaxed or extended length of this hose, so we are not quoting one. Because this is an aftermarket part rather than a Dyson original, fitting it can affect any remaining manufacturer warranty on the machine.
Frequently asked questions
How do I know the hose is the problem and not a clog?
Detach the hose and check that air moves freely through it end to end. If the machine pulls strongly at the port with the hose off and weakly with it on, the hose is leaking or blocked. Visible splits at either cuff confirm it.
Is this a genuine Dyson hose?
No. It is an aftermarket assembly built to replace the Dyson original, and it cross-references the Dyson part numbers listed above.
Does it fit a DC07 or DC14?
No. This assembly is listed for the DC17 family only. The DC07 and DC14 use different hoses.
Do I need special tools to fit it?
For most owners the hose is a hand-fit job at the cuffs. Consult your machine manual for the exact procedure on your model.
