Check a used cleaner as a complete system
Verify identity, included parts and replacement costs before comparing a used appliance with a complete alternative.
Updated:
Get the exact model and included-parts list
A used cleaner listing should identify the appliance and the equipment actually included. Ask for the model reference, the correct charger or mains arrangement where relevant, and a clear list of heads, hoses and accessories. Compare that list with the official model documentation instead of assuming every item shown in an original retail photograph is present.
The cylinder photograph illustrates why the body alone is not a usable setup for every task. Missing components can change the cost and practicality of a purchase. If the identity or included equipment cannot be established, keep the comparison unresolved rather than guessing which replacement part might fit.

Inspect condition without improvising repairs
Use the manufacturer's guidance for the model and seek competent assessment when condition is uncertain. Do not use a visibly damaged electrical appliance or improvise a charger, cable repair or battery substitution. This checklist is a buying organisation aid, not a repair procedure or a guarantee that a used machine is safe.
Ask the seller what maintenance has been performed and whether documentation is available. Treat unsupported claims as unanswered questions. A short demonstration may show that an appliance turns on, but it cannot establish remaining service life or every operating condition. Avoid opening electrical assemblies to investigate a possible bargain.
Calculate the ready-to-use subtotal
For a hypothetical listing at £70, assume a confirmed compatible missing tool costs £25 and required consumables cost £15. The ready-to-use subtotal is £110 before any delivery or other work. If a complete alternative costs an assumed £125, the apparent saving is £15, not the £55 difference between the headline prices.
Use current checked quotations for the exact parts when making a real decision. Do not count a repair as a simple consumable purchase, and do not assume an uncertain fault has a cheap fix. Keep unknown costs outside the subtotal with a clear note. If they are essential to using the machine, the comparison is not complete.
Verify the consumables and care instructions
Miele's UK finder demonstrates a model-specific approach to bags and filters. Use the appropriate official lookup for the appliance you are considering. A filter that resembles the pictured part may still be the wrong reference or may have different washing and replacement requirements.
For washable filters covered by Dyson's guidance, full drying is required before refitting. Ask about the condition of removable user-serviceable components, but do not assume a freshly washed appearance proves correct care. Save the manual and identify what permitted maintenance you would need to perform before normal use. Keep that work and any waiting time visible in the decision.

Choose only after the unanswered questions are resolved
Write down the model, included components, observed condition, verified replacement prices and anything still unknown. If the purchase depends on an unverified part or undocumented repair, pause the comparison rather than assigning a convenient zero to the uncertainty. A low headline price is not useful if the required configuration cannot be established.
As a final sensitivity check, an additional assumed £30 necessary part would raise the earlier £110 subtotal to £140, above the assumed £125 complete alternative. This is arithmetic, not a prediction of failure. It shows why identification and a full parts list matter before committing to a used appliance.
