Vacuum cleaner · Focused observation
The problem comes and goes
A short record of the programme, time into use and warning is helpful. An appliance working once between failures does not establish that the underlying problem has gone.
Model and requested work checked before an appointment is agreed.
How this relates to your vacuum cleaner
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.
Keep evidence and assumptions apart
Describe what you saw during ordinary use, then retain the complete model. An observation can help frame an assessment but does not establish which part is faulty.
When to stop demonstrating
Do not repeat a cycle to recreate smoke, tripping, burning, unsafe movement or leakage near electrical parts. Keep connected equipment in place and do not remove covers.
Your product, your place
