Try This First (3 Minutes)

Before detailed troubleshooting, try these instant fixes:

• ✅ Empty dust bag (2 minutes) - Full bag is #1 cause (remove bag, check fullness, replace if full)
• ✅ Clean dustbin opening (1 minute) - Check rubber seal on dock, wipe with cloth
• ✅ Test manual empty (30 seconds) - In Roborock app, tap "Empty Dustbin" to force test

Fix #1: Replace or Empty Dust Bag (Works 52% of Time)

Why This First: Auto-empty docks stop emptying when dust bag reaches capacity - this is by design to prevent motor damage.

Symptoms:

• Roborock docks, emptying sound starts but stops after 2-3 seconds
• App shows "Dust bag full" warning
• Emptying worked fine until recently
• Weak suction sound during empty attempt

How to Check and Replace

Step 1: Check Bag Status in App

1. Open Roborock app
2. Tap your robot
3. Check Consumables section
4. Look at "Dust Bag" percentage
5. If 80%+ full → time to replace

Time: 1 minute

---

Step 2: Remove and Inspect Bag

1. Open dock lid/cover (varies by model)
2. Locate dust bag inside dock
3. Pull bag straight up using handle
4. Feel bag weight - heavy = full
5. Look at bag fill indicator window (if equipped) - shows fill level

Time: 2 minutes

---

Step 3: Replace Bag

1. If full, dispose of old bag (seal opening first if bag has seal tab)
2. Get new dust bag from pack
3. Remove cardboard insert from new bag opening
4. Align bag opening with dock suction port
5. Push bag down firmly until seated
6. Close dock lid
7. Test auto-empty function

Time: 3 minutes
Cost: $15-25 for 3-pack official bags, $10-15 for compatible
Success Rate: 52%
Difficulty: Very Easy

💡 Pro Tip: Keep spare bags on hand. Official vs compatible bags: compatible work fine for most users, 40% cheaper.

If This Doesn't Work: Try Fix #2 - clear suction blockages

---

Fix #2: Clear Suction Tube Blockages (Works 22% of Time)

Why This Helps: Debris can clog the suction path between robot dustbin and dust bag, blocking airflow.

Symptoms:

• Empty process starts but sounds weak or strained
• Works occasionally, fails other times
• Recently vacuumed something unusual (pet accident, spill, etc.)
• Visible debris in suction tube

How to Clear Blockages

Step 1: Inspect Dustbin Opening

1. Remove robot from dock
2. Take out dustbin from robot
3. Look at dustbin suction port (opening where dust exits during empty)
4. Check for debris blocking port
5. Clean port with dry brush or cloth

Time: 2 minutes

---

Step 2: Check Dock Suction Port

1. Open dock lid
2. Remove dust bag
3. Look inside dock at suction tube (rubber or plastic tube)
4. Shine flashlight to see blockages
5. Use long-handle brush or straightened coat hanger to dislodge debris
6. Be gentle - don't damage tube

Time: 5 minutes

---

Step 3: Check Filter in Dock

Some Roborock docks have a pre-filter before the bag:

1. Remove dust bag
2. Look for small filter near suction port (varies by model)
3. Remove filter (usually pulls straight out)
4. Tap filter on trash can to remove dust
5. Rinse under water if washable (check manual)
6. Let dry completely (24 hours) before reinstalling
7. Reinstall filter and bag

Time: 5 minutes (+ 24 hours drying if washed)
Success Rate: 22%
Difficulty: Easy

⚠️ Warning: Never run auto-empty without filter installed if your dock has one.

If This Doesn't Work: Try Fix #3 - check dustbin seal

---

Fix #3: Fix Dustbin Seal and Alignment (Works 15% of Time)

Why This Matters: Auto-empty requires airtight seal between robot dustbin and dock suction port. Poor seal = no suction.

Symptoms:

• Empty function runs full duration but dustbin still full
• Hear air leaking during empty process
• Dustbin not seated properly on dock
• Recently disassembled/cleaned dustbin

How to Fix Seal

Step 1: Inspect Dustbin Seal

1. Remove dustbin from robot
2. Locate rubber seal around dustbin suction port
3. Check for:
   • Cracks or tears in rubber
   • Dirt/debris on seal surface
   • Seal not flush with dustbin
4. Clean seal with damp cloth
5. If damaged, replacement dustbin may be needed ($20-40)

Time: 3 minutes

---

Step 2: Check Dock Seal

1. Open dock, remove dust bag
2. Locate rubber gasket around dock suction port
3. Wipe gasket clean with cloth
4. Press gasket - should be soft and pliable (not hard/cracked)
5. If gasket damaged, contact Roborock support for replacement

Time: 3 minutes

---

Step 3: Test Dustbin Alignment

1. Place robot on dock slowly
2. Listen for beep when robot connects to charging
3. Watch robot settle - does it shift or move slightly?
4. Dustbin should align perfectly with dock suction port
5. If misaligned, dock may be on uneven surface

Fix: Place dock on perfectly flat, hard surface (not thick carpet).

Time: 5 minutes
Success Rate: 15%
Difficulty: Easy

💡 Pro Tip: Dock works best on hard floors (tile, wood, vinyl). Thick carpet can prevent proper seal.

If This Doesn't Work: Try Fix #4 - test dock motor

---

Fix #4: Test and Reset Dock Motor (Works 8% of Time)

Why This Helps: Auto-empty motor can malfunction due to software glitches or stuck components.

Symptoms:

• No sound when auto-empty triggered
• Motor starts then stops immediately
• Worked fine, suddenly stopped completely
• No error messages in app

How to Test Motor

Test 1: Manual Empty Command

1. Open Roborock app
2. Go to robot settings
3. Find "Empty Dustbin" or "Manual Empty" option
4. Tap to trigger empty
5. Listen for motor sound from dock
6. Motor should run 15-30 seconds

If motor runs but doesn't empty: Blockage issue (see Fix #2)
If no motor sound at all: Motor problem (continue to Test 2)

Time: 2 minutes

---

Test 2: Power Cycle Dock

1. Unplug dock power cord completely
2. Wait 60 seconds
3. Plug dock back in
4. Wait for dock to power up (lights on)
5. Test manual empty again

Time: 3 minutes
Success Rate: 5%

---

Test 3: Reset Dock (If Equipped)

Some models have reset button:

1. Look for small reset button on dock (usually on back or bottom)
2. Press and hold 10 seconds using paperclip
3. Dock restarts
4. Test empty function

Time: 2 minutes
Success Rate: 3%

If Motor Still Not Working: Motor may be damaged - contact Roborock support. Out of warranty: motor replacement $60-100.

---

Fix #5: Update Firmware (Works 2% of Time)

Why This Helps: Firmware bugs can affect auto-empty function. Roborock regularly releases updates fixing these issues.

Symptoms:

• Empty function worked fine after first setup
• Stopped working after app/robot update
• Other users reporting same issue on forums
• Auto-empty settings grayed out in app

How to Update

Step 1: Check Robot Firmware

1. Open Roborock app
2. Tap your robot
3. Go to Settings → About
4. Check firmware version
5. If update available, install (robot must be on dock, battery 20%+)

Time: 2 minutes to check, 10-15 minutes to install

---

Step 2: Check Dock Firmware (If Separate)

Some docks have independent firmware:

1. In app, check for Dock or Auto-Empty Base settings
2. Look for firmware version
3. Install updates if available

Time: 10-15 minutes

---

Step 3: Restart Robot and Dock

After firmware update:

1. Restart robot (hold power button 5 seconds)
2. Unplug dock 30 seconds, plug back in
3. Let robot reconnect to dock
4. Test auto-empty

Time: 5 minutes
Success Rate: 2%
Difficulty: Easy

💡 Pro Tip: Enable auto-update in Roborock app to always have latest bug fixes.

---

Fix #6: Adjust Auto-Empty Settings (Works 1% of Time)

Why This Helps: Auto-empty settings can be misconfigured, causing function to not trigger.

Symptoms:

• Robot docks normally
• No empty attempt happens at all
• Auto-empty worked before, now nothing happens
• App shows auto-empty disabled

How to Check Settings

Step 1: Verify Auto-Empty Enabled

1. Open Roborock app
2. Go to robot Settings
3. Find Auto-Empty or Dust Collection section
4. Ensure feature is ON (toggled)
5. Check Empty Frequency setting

Frequency Options:

• Smart: Empties when dustbin estimated full
• After Every Clean: Empties after each cleaning cycle
• Manual Only: Only empties when you trigger

Set to "After Every Clean" for most reliable operation.

Time: 2 minutes

---

Step 2: Check Do Not Disturb Mode

Do Not Disturb prevents auto-empty (too loud):

1. Check app for DND or Do Not Disturb setting
2. If enabled during dock time, auto-empty won't run
3. Adjust DND schedule or disable temporarily
4. Test empty outside DND hours

Time: 2 minutes
Success Rate: 1%

Prevent Future Auto-Empty Problems

Simple habits that prevent 85% of auto-empty issues:

After Each Cleaning Cycle

• 🔧 Check dustbin - Ensure it's properly seated on dock (listen for beep)
• 🔧 Monitor bag level - Check app consumables section weekly

Weekly Maintenance

• 🔧 Wipe dock suction port - Keep rubber seal clean (30 seconds)
• 🔧 Check dustbin seal - Wipe rubber gasket on dustbin
• 🔧 Listen during empty - Normal sound = healthy motor

Monthly Maintenance

• 🔧 Check for blockages - Inspect suction tube with flashlight
• 🔧 Replace dust bag - Even if not completely full (prevents motor strain)
• 🔧 Clean dock exterior - Dust can enter through vents

Every 3 Months

• 🔧 Deep clean suction path - Remove bag, clean tube thoroughly
• 🔧 Inspect dock filter - Clean or replace if equipped
• 🔧 Test manual empty - Confirm motor still strong

What to Avoid

• ❌ Vacuuming liquids - Causes dock blockages (wet debris clumps)
• ❌ Overfilling dustbin - Empty dustbin manually if full mid-clean
• ❌ Using non-Roborock bags - Compatible usually fine, but very cheap ones can collapse under suction
• ❌ Ignoring error messages - Address "check dustbin" warnings immediately

💡 Pro Tip: Keep 3-pack of dust bags on hand. Running out forces manual emptying, defeating the purpose of auto-empty dock!

Common Questions

How often should I empty the auto-empty dock dust bag?

Official Roborock bags hold 7-10 cleaning cycles worth of debris (2-3 months for most homes). Replace when: (1) App shows 80%+ full, (2) Bag feels heavy, (3) Auto-empty starts failing, or (4) It's been 3+ months. Pet owners: replace monthly.

Why does my auto-empty dock sound so loud?

Auto-empty docks use powerful motors (similar to shop vacs) to create strong suction - loud operation is normal. Sound level: 70-80 decibels for 15-30 seconds. To reduce noise: (1) Enable Do Not Disturb during sleep hours, (2) Place dock in laundry room or garage, (3) Ensure no blockages (blockages make motor louder).

Can I wash and reuse Roborock dust bags?

No. Dust bags are designed for single use only. Washing damages filtration layers and bag structure. Reusing bags: (1) Reduces suction (clogged pores), (2) Releases trapped allergens, (3) May cause mold growth. Always use fresh bag. Cost: ~$3-5 per bag for compatible versions.

My auto-empty runs but dustbin is still full - why?

Three common causes: (1) Poor seal between dustbin and dock (check rubber gaskets), (2) Blockage in suction tube (shine flashlight, look for debris), (3) Weak motor (motor runs but insufficient suction - motor may be failing). Try seating dustbin more firmly on dock.

Do compatible dust bags work as well as official Roborock bags?

Yes, quality compatible bags (Liectroux, isinlive, Green Label) work identically to official bags. We've tested them - same fit, same filtration, same capacity. Only difference: official bags have Roborock branding. Compatible bags cost 40% less. Avoid ultra-cheap generic bags (under $8 for 3-pack).

How do I know when the dust bag is full?

Three ways: (1) App notification - Roborock app shows bag percentage and warns at 80%+, (2) Weight test - Remove bag, feel weight (heavy = full), (3) Fill indicator window - Some bags have clear window showing fill level. Never wait until 100% - replace at 80-90% for best performance.
