Shark robot vacuums are designed to simplify your cleaning routine, but like any tech device, they can encounter issues. One common problem is the clean and dock lights flashing, which can indicate various underlying issues. Understanding these indicators and knowing how to troubleshoot them is essential for maintaining optimal performance.

Normal Functionality of Lights
Shark robot vacuums are equipped with several lights and indicators that provide information about their status. The clean light typically illuminates when the vacuum is in operation, while the dock light indicates the charging status when the robot is on its dock. The charge indicator lights show the battery level, cycling while charging and remaining steady when fully charged. Understanding these normal behaviors helps you identify when something is amiss.
Abnormal Light Behavior
Abnormal light behavior, such as flashing patterns, often signals an issue that needs attention. For example, a red flashing clean light usually indicates a problem preventing the vacuum from functioning correctly. Similarly, the dock and spot LED lights flashing together or alternately can point to software glitches, hardware issues, or navigation system problems. Identifying the specific pattern is the first step in diagnosing and resolving the issue.
Troubleshooting Clean Light Flashing Issues
Red Flashing Clean Light
A red flashing clean light can stem from several causes, including clogged brushes, a full dustbin, filter issues, or software/hardware malfunctions. To troubleshoot, start by inspecting the brushes and wheels for blockages and cleaning them if necessary. Next, empty the dustbin and check the filter for dirt or damage. If the issue persists, ensure the vacuum’s software is up to date or consider resetting the device to factory settings.
Other Clean Light Issues
Other clean light issues, such as unusual flashing patterns or colors, may also arise. Regular maintenance, including cleaning the filter and emptying the dustbin after each use, can prevent many of these problems. Additionally, keeping the software updated ensures the vacuum operates smoothly.
Troubleshooting Dock and Spot LED Light Issues

Flashing Together
When the dock and spot LED lights flash together, it often indicates a software glitch, hardware issue, or navigation system problem. Begin by restarting the robot and checking for software updates. Ensure the robot is properly calibrated and that its sensors and charging pads are clean. If the problem continues, a factory reset may be necessary.
Flashing Alternately
Alternate flashing of the dock and spot LED lights typically points to connection and charging issues, software or firmware problems, or hardware malfunctions. Verify that the robot is securely connected to its dock and that the charging process is functioning correctly. Updating the software and inspecting the hardware can often resolve this issue.
Advanced Troubleshooting and Maintenance
Resetting the Robot
If basic troubleshooting steps don’t resolve the issue, resetting the Shark robot vacuum to factory settings can help. This process clears any software glitches and restores the device to its original state. However, use this as a last resort, as it will erase any saved settings or maps.
Contacting Customer Support
For persistent issues, contacting Shark’s customer support is the next step. Provide detailed information about the problem, including the light patterns and any troubleshooting steps you’ve already taken. Customer support can offer further assistance or arrange for repairs if needed.

Regular maintenance is key to preventing issues and ensuring optimal performance. Clean the filters weekly, replace them every two months, and empty the dustbin after each use. Inspect and clean the brushes, wheels, and sensors periodically. Keeping the software updated also helps avoid software-related problems.
