Quick Diagnosis: Why Won't It Start?

Before fixing, identify which type of "won't start" you're experiencing:

Type 1: No Response at All

• Press button, nothing happens
• No lights, no sounds
• Robot appears completely dead

Type 2: Lights/Sounds but Won't Clean

• Button press makes lights flash or beep
• Error message in app
• Robot acknowledges command but won't execute

Type 3: Starts Then Stops Immediately

• Robot begins moving
• Stops within seconds
• Returns to dock or just stops mid-floor

Type 4: App Command Fails

• Physical button might work
• App commands don't start cleaning
• Connection issues suspected

Try This First (3 Minutes)

Quick checks for all "won't start" scenarios:

• ✅ Check battery level (10 seconds) - Below 20% may prevent starting
• ✅ Press and hold button (5 seconds) - Ensure robot is actually on
• ✅ Check for errors in app (30 seconds) - May explain why it won't start
• ✅ Remove and reseat dustbin (30 seconds) - Misaligned bin prevents startup
• ✅ Check mop attachment (30 seconds) - If equipped, ensure it's seated properly
• ✅ Lift robot off dock and press clean (30 seconds) - Rules out dock issues

↳ Most Common Cause: Low battery or unseated dustbin (34% of startup failures).

Fix 1: Charge and Power Cycle (Works 34% of Time)

Best For: Type 1 (No response) or Type 2 (Lights but won't clean)

Why This Works: Roborock won't start cleaning below certain battery thresholds, and power cycling clears temporary glitches.

Symptoms:

• Robot responds slowly or not at all
• Battery indicator shows low or won't show
• Robot tries to start then immediately docks
• App shows low battery warning

How to Fix:

Step 1: Verify Power

1. Check robot power switch is ON (some models have switch on bottom/side)
2. Place robot on dock
3. Verify dock is plugged in and has indicator light
4. Wait for robot to show charging indicator

Step 2: Full Power Cycle

1. Hold power button 5 seconds until robot turns off
2. Remove robot from dock
3. Wait 30 seconds
4. Hold power button to turn on
5. Place back on dock
6. Let charge for 30+ minutes before testing

Step 3: Check Battery Level

1. Open Roborock app
2. Check battery percentage
3. If below 20%, let charge to at least 30%
4. Try starting clean

Time: 5 minutes (plus charging) Cost: Free Success Rate: 34%

💡 Pro Tip: Roborock reserves some battery for returning to dock. If battery is low, it won't start a cleaning cycle to prevent getting stranded.

How to Fix - Dustbin:

1. Remove dustbin completely
2. Inspect bin:
   • Check for damage
   • Empty if needed
   • Clean filter
3. Check bin sensor contacts:
   • Look at where bin connects to robot
   • Wipe contacts with dry cloth
4. Reinstall firmly:
   • Push until you hear/feel click
   • Shouldn't be loose
5. Test startup

How to Fix - Mop Attachment (S7, S8, Q7 models):

1. Check mop plate installation:
   • Should be fully seated
   • Magnets aligned properly
2. Check water tank:
   • Has water (if using mop)
   • Properly inserted
3. Remove mop if not using:
   • Some settings won't start mopping on carpet
   • Try with mop removed to test
4. Test startup

Common Questions

My Roborock button lights up but won't start cleaning - why?

Usually an error preventing startup. Check the app for specific error message. Common causes: cliff sensors need cleaning, dustbin not seated, mop tank empty (if mop mode enabled), or battery too low. Address the specific error shown.

The robot says "Starting cleaning" but then immediately docks - why?

Battery is likely below the threshold for a full clean. Roborock reserves battery for returning home. Charge to at least 30-40% before starting. Also check if scheduled cleaning overlapped with charging - it may have tried while not ready.

Why won't my Roborock start from the app but the button works?

Connection issue between app and robot. Check that robot shows "online" in app. If offline, reset robot's Wi-Fi connection and re-pair in app. Also verify phone and robot are on same 2.4GHz network.

My Roborock beeped and now won't start at all - what happened?

The beep pattern may indicate specific error. Check app for error code. Common issues: picked up during cleaning (confused sensors), dust in cliff sensors, or hardware error. Power cycle and clean sensors. If problem persists, note the error code for support.

Can I start my Roborock without the app?

Yes, press the main button on top. Single press starts full cleaning. Some models have spot clean button too. App is not required for basic operation - just for scheduling, mapping, and advanced features.
