Vacuum Troubleshooting Guides
Every guide on this site solves one specific symptom on one type of cleaning machine — a vacuum that won’t start, a robot that won’t dock, a mop leaving streaks. They are written to be used while you are standing over the machine, so each one opens with a direct answer and the first checks to make.
They are also deliberately brand-neutral. Cordless vacuums, robots and mops share the same handful of subsystems whoever made them, so every fix here is diagnosed by behavior rather than by model number. That matters most if your machine came from a marketplace listing with no manual and no support line — you can still work out what is wrong. Where something genuinely varies between models, such as what a particular blinking light means, we say so and point you at your manual instead of inventing a code table.
