How do I set up a robot vacuum so it actually works?
Preparing the house rather than the robot, the first mapping run, and the maintenance that stops it degrading.

Short answer
Most of the setup is to the house, not the machine: cables cleared, light objects moved, thresholds checked and no-go zones set. Run the first mapping pass with the house tidy and in daylight, then empty the bin and clean the brush regularly or performance falls off within weeks.
A robot vacuum works well or badly depending almost entirely on the environment it is given, which is why the same model delights one household and is abandoned by another.
Safety
Step by step
- Do a proper tidy before the first run.Cables, phone chargers, shoelaces, socks, small toys, rugs with tassels, pet bowls. The first run defines the map and it also decides whether the robot survives it — cables are the main cause of failure.
- Tie up or clip every trailing cable.Cable clips along the skirting or ties behind furniture. A robot that eats a lamp cable stops mid-room and it happens on the first run more than any other time.
- Place the dock properly.Against a wall on a hard floor, with clear space either side and in front as the manual specifies, and not in a corner or under furniture. A dock it cannot find reliably means it strands itself.
- Run the first mapping pass deliberately.House tidy, all internal doors open, curtains open if it uses a camera. That first map is what everything afterwards depends on, so it is worth setting up for.
- Name and edit the rooms afterwards.Splitting and naming rooms in the app is what makes 'clean the kitchen' possible. It takes five minutes and it is the difference between a useful device and one that only does whole-house runs.
- Set no-go zones.Around pet bowls, a floor-standing lamp, cables you cannot move, a child's play area, a rug it keeps getting stuck on. Virtual barriers are more reliable than hoping.
- Check thresholds and floor changes.Most manage about 20mm. A higher threshold, a thick rug edge or a step means it either fails to cross or gets stranded on the other side. Measure the ones that matter.
- Deal with dark flooring.Cliff sensors read very dark mats and flooring as a drop and refuse to cross. It is a common and confusing problem, and moving the mat or covering the sensor issue is the only practical answer.
- Schedule it for when you are out.They are noisy and work best on empty floors. Mid-morning on weekdays is the usual answer, and scheduling is what makes it maintain the house rather than just clean it occasionally.
- Empty the bin every run or two.The onboard bins are small and suction falls off sharply when full. This is the most common reason people conclude it has stopped working well.
- Cut hair off the brush weekly.Hair wraps the main brush and the side brush and stops them turning. Most come with a small cutting tool. With pets or long hair it needs doing more often.
- Clean the sensors and wipe the charging contacts.A dry cloth over the cliff sensors and the dock contacts. Dusty sensors cause erratic behaviour and failure to dock, and it takes seconds.
- Wash or replace the filter.Monthly, and every few months for replacement. A clogged filter reduces suction considerably and is easy to forget entirely.
- Understand what it will not do.Corners, stairs, deep pile carpet, large debris and edges are all weak points. It maintains a level of cleanliness between proper vacuuming rather than replacing it.
- Check the mopping function honestly.Most robot mops spread a damp cloth over the floor. Useful for dust and light marks, not a substitute for mopping a kitchen properly.
Tips
- Spend an hour on cables and clutter before the first run. It is the single thing that determines whether the robot succeeds.
- Empty the bin every run or two. Almost every 'it stopped picking up' complaint is a full bin or a hair-wrapped brush.
- Name the rooms in the app. It converts a whole-house device into one you can send to the kitchen after dinner.
Common mistakes
- Running it before clearing cables and small objects — It wraps cables round the brush and stops, and the first run also creates the map. Cables are the main cause of failure and of frustration.
- Never cleaning the brush and filter — Hair wraps the brush and the filter clogs, and suction falls off within weeks. Most people conclude the machine has failed when it needs five minutes of maintenance.
If it doesn't work
Not picking up as well as it did
Cause: Full bin, hair-wrapped brush or clogged filter — Fix: Empty the bin, cut the hair off both brushes, and wash or replace the filter.
Refuses to cross a dark mat or floor
Cause: Cliff sensors reading very dark surfaces as a drop — Fix: Move the mat or set a no-go zone. It is a sensor limitation rather than a fault.
Gets stuck in the same place every time
Cause: A threshold, a rug edge or low furniture — Fix: Set a no-go zone there, or fit a small ramp at the threshold.
Cannot find the dock
Cause: Dock obstructed, dirty contacts, or map corruption — Fix: Clear the space either side of the dock as the manual specifies, wipe the contacts, and remap if it persists.
Map keeps changing or resetting
Cause: Doors closed on different runs, or furniture moved — Fix: Keep internal doors open during cleaning runs and remap after any significant rearrangement.
Questions people ask
Why has my robot vacuum stopped picking up properly?
Almost always a full bin, hair wrapped around the brushes, or a clogged filter. Empty the bin every run or two, cut hair off the brushes weekly, and wash the filter monthly.
Why does my robot vacuum avoid a dark rug?
Its cliff sensors read very dark surfaces as a drop and it refuses to cross. Moving the rug or setting a no-go zone is the practical answer — it is a sensor limitation, not a fault.
