How to Maintain a Robot Vacuum
Robots run themselves, but only if the basics are maintained — the checklist that keeps yours cleaning.
A robot vacuum is a reliable daily promise only while its backups are maintained. The failure pattern is predictable: filters clog, side brushes wear, sensors smear, docks grime. This is the 10-minute routine that keeps the robot defending your floors.
Weekly: empty the bin (or empty dock)
Robots sweep much less volume than a stick, so the bin fills slowly — but auto-empty docks still need bag changes on schedule, and bins need the brushroll check.
Fortnightly: wash filters
Filters are the silent killer: a clogged filter drops airflow, and the robot keeps running on a declining baseline. Rinse cold and air-dry fully.
Monthly: clean the sensors and camera
Dust on obstacle sensors and the mapping camera produces ghost walls and missed corners. A dry wipe restores mapping navigation.
Quarterly: replace side brushes and rotate rollers
Side brushes are consumables — replace when the bristles bend. Check the main brushroll for hair; most modern units cut hair automatically but the debris tray still needs clearing.
Seasonal: deep-clean the dock
The auto-empty base and (on mop robots) clean water tanks accumulate grime; seasonally wipe the base plates and sanitise water tanks.

How often should I replace robot vacuum filters?
Every 2–3 months with fortnightly washing — treat filter life as engagement, not calendar.
Why is my robot missing spots?
Check the obstacle sensors and camera first — cleaned sensors fix the map's blind spots before you ever rebuild it.
