Corrections are acted on. Requests for a diagnosis of a specific machine are not something this site can responsibly answer, and the diagnostics are a better use of your time than waiting for a reply.
Partnership and affiliate enquiries are welcome through the same address. Product samples are not, because nothing here is tested and accepting hardware would imply otherwise.
Common questions
What should I include in a correction?
The page, the figure you think is wrong, and where the correct one comes from, ideally a manual or a manufacturer specification. Every number on this site is labelled as either a published standard or a service convention, so it also helps to say which of those you think has been misapplied.
Can you tell me what is wrong with my vacuum?
Not reliably, and it would be irresponsible to try from a description. The diagnostics work through the causes in the order a service counter uses and explain what each result would mean, which is genuinely more useful than a guess from someone who cannot see the machine. Start with suction loss triage.
Do you accept products for review?
No, because nothing on this site is tested and accepting hardware would create an obligation the site cannot honestly discharge. Recommendations come from published specifications, current listings and verified owner reports, and keeping it that way is what makes the roundups worth reading.
Every figure here comes from published manufacturer specifications, owner reported measurements and repair documentation, and each is labelled as either a standard or a convention. This is researched general information to help you diagnose and plan, not professional advice, and it cannot tell you what is wrong with one particular machine. Your own manual and the part number printed on your machine are the final word.
