Robot Vacuum Troubleshooting: Stuck, Not Charging, Weak Suction and More

Fixes for common robot vacuum problems: getting stuck, not charging, weak suction, not returning to dock, app connection and mapping errors.

This guide is based on manufacturer specifications, published information and buyer feedback. We do not claim hands-on testing. Always follow the instructions that come with your own robot vacuum.

Here are common robot vacuum problems and the basic checks to try first. Steps differ by model, so use your manual for details.

It keeps getting stuck

  • Pick up cables, socks and small objects before a run.
  • Check for thresholds, rug fringes and dark rugs that can confuse cliff sensors.
  • Use no-go zones in the app for problem areas.

It will not charge

  • Clean the charging contacts on the robot and dock.
  • Check the dock is plugged in and has clear space around it.
  • Try another outlet and check the battery as the manual advises.

Weak suction

  • Empty the bin and clean the filter.
  • Clear hair from brushes and the suction path.
  • Check for blocked inlets and a full dock bag.

It does not return to the dock

  • Keep the dock in an open spot with a clear path.
  • Clean the dock sensors.
  • Check the robot has a clear map and the dock location is correct.

App or Wi-Fi problems

  • Check your home network band; many robots need 2.4 GHz.
  • Move the router or add coverage near the dock.
  • Update the app and robot firmware.

Strange behaviour or wrong maps

  • Wipe all sensors and cameras.
  • Rebuild the map after moving furniture.
  • Restart the robot as the manual describes.

When to contact support

If basic fixes do not help, note the model, error code and what you tried. Check the warranty period and keep your receipt. See how to maintain a robot vacuum.

  1. Look at the app for error messages.
  2. Clean the brushes, wheels and sensors.

  5. Update the app and firmware.
