Enquiry preparation
Vacuum cleaner: keep a note of the different occasions
For a vacuum cleaner enquiry: Retain settings and outcomes from ordinary use already observed. An intermittent issue can be difficult to describe from memory. Do not run further demonstrations of smoke, tripping or dangerous leakage.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Describe which function changed, any warning and the charging behaviour where relevant. The team must confirm the actual model and requested work before accepting a small-appliance enquiry.
Why this belongs in the enquiry
The vacuum cleaner reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Before arranging a visit
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
