Premium kit
Quick answer
A printable maintenance and diagnostics kit is in preparation. Everything needed to keep a household vacuum running is already free on this site, in the diagnostics and the parts finder.
In preparation
A printable maintenance and diagnostics kit is being put together: the checking orders, the filter and belt schedules, and a log to keep with the machine so the intervals are recorded where the work actually happens.
In the meantime everything it will contain is already on this site and free. The five diagnostics are the place to start, and the parts finder covers what each check ends at.
Common questions
What will the kit contain?
A printable version of the diagnostics, the filter and belt schedules, and a maintenance log to keep with the machine, so the checks can be run at the cupboard rather than at a screen. Everything in it is derived from what is already published free on this site.
Is anything on this site behind a paywall?
No. Every diagnostic, every reference table and every parts page is free and will stay that way. The kit is a convenience format for people who would rather work from paper, not a way of gating anything that is currently open.
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.
