If your Roborock vacuum isn’t working properly – whether it’s sensor errors, cleaning issues, or docking failures – running a built-in self-test can help. To enter Roborock BIT mode: remove the robot from the docking station, turn it off, then hold down the ⏻ Power button and quickly press the 🏠 Home button five times in a row. This activates Roborock test mode for diagnostics. This guide explains how to run the test and what each step means.
🤖 Which Roborock Models Support BIT Mode
BIT (Built-In Test) mode is available on many Roborock models with advanced diagnostic capabilities. These typically include:
- Roborock S7 Series
- Roborock S8 Series
- Roborock Q7 Series
- Roborock Q8 Series
- Roborock X Series
- Roborock T Series
Models with voice feedback, multi-sensor arrays, and smart docking stations are more likely to support BIT mode. If unsure, check your model’s manual or contact Roborock support.
🛠️ How to Enter Roborock BIT Mode
- Remove the robot from the dock and power it off by holding ⏻ Power button.
- Hold the ⏻ Power button and press the 🏠 Home button five (5) times quickly.
- Release all buttons. The robot will announce BIT mode and light up all LEDs.
- Press ⏻ Power button once, then 🏠 Home button once to begin the test.
- Use 🏠 Home button to move forward through tests; ☐ Spot cleaning to go back.

⚠️ Common Issues BIT Mode Can Identify
BIT mode helps detect hardware and sensor faults that may cause cleaning or navigation problems. Common issues include:
- Brush motor failures (side or main brush not spinning)
- Sensor malfunctions (cliff, wall, bumper sensors)
- Water tank detection errors or missing water level signals
- Wheel overcurrent or movement issues due to obstructions
- LIDAR or camera faults affecting mapping/navigation
- Charging circuit problems or docking failures
- IR communication failures (positioning errors)
- Microphone or Wi-Fi module issues (connectivity problems)
If BIT mode reports a “Fail” or no response, clean the affected part, check for firmware updates, or refer to the official Roborock repair guide.
And if you’re managing other smart devices, like a NAS system, it’s just as important to follow proper shutdown procedures to avoid damage. See our guide on Shutdown Synology NAS Safely: Avoid Critical Errors for best practices.
✅ Conclusion
BIT mode is a built-in tool for smart vacuum diagnostics. It helps identify issues like brush failure, cliff sensor errors, or water tank detection problems. Use it for regular maintenance or when troubleshooting cleaning problems, firmware issues, or dock errors. It’s a simple way to keep your Roborock running smoothly.
