How to fix it

  1. Carry robot back to Home Base manually.
  2. Leave doors open during cleaning cycles.
  3. Keep Home Base in a permanent location with 1.5 ft clearance on each side and 4 ft in front.
  4. On i/j/s/900 series, wipe the camera lens on top of the robot with a soft dry cloth.
  5. Ensure rooms have adequate ambient light during scheduled cleans.
  6. Re-train smart maps in the iRobot app if room layout changed significantly.

Why it happens

Typical signs: 'Error 17' voice prompt · Robot stops in unfamiliar area · Couldn't dock at end of cleaning

  • Doors closed during cleaning Robot left a room it can't get back to.
  • Home Base moved Dock was relocated mid-cycle, breaking the mental map.
  • Furniture rearranged Major changes to the room confuse vSLAM-based navigation (i/j/s series).
  • Dirty camera lens (vSLAM models) Top-mounted camera covered in dust can't navigate visually.
  • Low light conditions vSLAM models need ambient light to navigate.
