Roborock robot vacuum announces “Error 8” / “Dustbin is not installed” even though the bin appears to be in place.

Safety first: Power off the robot before removing the dustbin.

Step-by-step:

• Remove and reseat dustbin: Pull out the dustbin completely, check for debris on the rails, then slide it back in firmly until it clicks.
• Inspect dustbin tabs: Look for small plastic tabs or protrusions on the dustbin that engage the internal switch. If a tab is broken, the robot may not detect the bin.
• Clean detection area: Use a dry cloth or compressed air to clean the dustbin cavity, especially around any small switches or optical sensors.
• Try a different bin (if available): If you have a spare or replacement dustbin, install it to see if the error clears.

If the error remains: The dustbin detection switch or sensor on the main body may be faulty and require internal repair or replacement.
