Enquiry preparation
Vacuum cleaner: mention a relevant recent change
For a vacuum cleaner enquiry: A moved appliance, interruption or different setting may provide context. Describe what actually happened and avoid treating timing alone as proof of a cause.
Model and requested work checked before an appointment is agreed.

Apply this to your product
Identify the corded, cordless or robot product and explain which function changed. Ask about the actual model and requested work before assuming it can be accepted.
Why the detail helps
The vacuum cleaner reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Before an appointment is agreed
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
