Does the robot circle, click, drag, or consistently pull toward one side?
One-sided travel makes a wheel, track, caster, drive module, or dragging brush more likely than a map-only problem.
If yes, possible repair paths include:
Vacuum symptom guide
Why Is My Robot Vacuum Navigating Incorrectly?
Navigation trouble describes circling, drifting, missed areas, false obstacle detection, localization errors, or repeated stops away from the dock. Wheels or tracks, cameras, LiDAR, cliff and bumper sensors, brush drag, battery runtime, mapping state, and controls can produce different versions of that behavior.
Important distinction
A symptom is not a repair diagnosis
The same symptom can come from several assemblies. The options below explain what our technician may inspect; final diagnosis, parts selection, and pricing happen through professional service.
Compare the clues
What else is happening?
You do not need to test or take apart the vacuum. If you have already noticed one of these combinations, it can help narrow which professional repair is most likely.
Does the error occur mainly near stairs, dark flooring, mirrors, or strong direct light?
Surface- or lighting-dependent behavior points toward the camera, cliff, bumper, LiDAR, or another sensing system interpreting the room incorrectly.
If yes, possible repair paths include:
Does the robot lose power before finishing a route or returning to the dock?
Incomplete routes paired with rapidly falling charge can make lost battery capacity part of the navigation complaint.
If yes, possible repair paths include:
Do movement and sensor behavior appear normal while localization or mapping remains consistently wrong?
When drive and sensor inputs are confirmed, a navigation or main control fault becomes a more credible service path.
If yes, possible repair paths include:

Repairs that can fit this symptom
These are professional service possibilities, not a definitive diagnosis. Our technician confirms the failed assembly before recommending or pricing a repair.
Robot Drive RepairPossible professional repairThis repair becomes more likely when:Circling, dragging, clicking, or uneven travel follows one wheel, track, caster, or drive module.View professional serviceRobot Sensor RepairPossible professional repairThis repair becomes more likely when:The behavior follows a camera, cliff sensor, bumper sensor, LiDAR unit, or other sensing module.View professional serviceBattery ReplacementPossible professional repairThis repair becomes more likely when:The robot loses the runtime or stable voltage needed to finish navigation and return normally.View professional serviceBrush Roll RepairPossible professional repairThis repair becomes more likely when:A jammed main or side brush adds drag or triggers an error that interrupts navigation.View professional serviceControl Board RepairPossible professional repairThis repair becomes more likely when:Drive and sensor inputs test correctly but a confirmed navigation or main controller remains faulty.View professional service
Service timing
Schedule service before the problem gets worse
Navigation errors can strand the robot, create repeated impacts, and overload a dragging drive or brush. Service is especially worthwhile when the same physical direction, sensor error, or route failure repeats across cleaning cycles.
Useful service details
What to tell our technician
Share only what you have already observed. These details are specific to robot navigation or sensor trouble and help us arrive prepared without asking you to open or test the machine.
- Whether the robot circles, drifts, stops, misses rooms, or reports a named sensor error
- Whether the behavior occurs everywhere or only near stairs, dark surfaces, mirrors, or strong light
- Whether one wheel, track, caster, bumper, or brush is obstructed while power is off
- Whether a map reset or documented restart changes the behavior without changing the hardware
Repair intake
Still not sure which repair fits?
Start with the make, exact model, photos, and what the vacuum is doing. Inspection confirms the failed assembly before we source service parts or begin repair work.
