Fix 1: Remove Hair from Main Brush (Works 68% of Time)

Yep, this is hands-down the most common issue.

Why This First: Dreame's main roller brush accumulates hair fast, especially long human hair or pet fur. Hair wraps around brush ends, jamming the motor.

Symptoms:

• Main brush not spinning at all
• Brush spins slowly or intermittently
• Grinding or whining noise from brush area
• Cleaning performance suddenly dropped
• Recently vacuumed long-hair area

How to Fix:

Step 1 - Remove Main Brush:

For Dreame L10s/L10 Pro/L20 Ultra:

1. Flip Dreame upside down on soft surface
2. Locate main brush cover (center, between wheels)
3. Push release clips on both sides
   • Clips usually marked with arrows
   • Squeeze both simultaneously
4. Lift cover off
5. Pull brush straight out
   • Brush slides out from one side
   • Note which end has bearing cap

For Dreame D10/D10 Plus:

1. Flip robot upside down
2. Find brush cover (rectangular panel)
3. Twist cover 90 degrees counterclockwise
4. Lift cover off
5. Pull brush out

For Dreame W10/W10 Pro (Mop models):

1. Flip upside down
2. Remove mop pads first (if attached)
3. Brush cover near front
4. Push clips, remove cover
5. Extract brush

Step 2 - Inspect Hair Buildup:

1. Check both brush ends (bearings)
   • Hair wraps around gray/white bearing caps
   • Creates tight "donut" of tangled hair
2. Check brush bristles
   • Hair wrapped in bristles
   • Debris caught in rubber fins
3. Check brush axle
   • Hair on metal shaft itself

Step 3 - Remove Hair:

Method 1 - Scissors (Fastest):

1. Use scissors to cut hair wraps
   • Cut along brush length
   • Don't cut bristles or rubber fins
2. Pull hair away from bearings
3. Unwind remaining hair
4. Takes 2-3 minutes

Method 2 - Cleaning Tool (Thorough):

1. Use Dreame cleaning tool (included with robot)
   • Small plastic blade with comb
2. Slide blade under hair wrap
3. Cut and pull hair free
4. Comb bristles to remove embedded hair
5. Takes 5 minutes, more thorough

Step 4 - Clean Brush Housing:

1. While brush removed, inspect housing
2. Remove debris from brush cavity
   • Use fingers or vacuum
   • Check both ends where brush sits
3. Wipe bearing sockets clean
   • Small circular sockets at each end
   • Dust/hair can jam here too

Step 5 - Reinstall Clean Brush:

1. Align brush with housing
   • Square end fits specific side
   • Round bearing cap on other side
2. Slide brush in until fully seated
   • Should sit flush, not sticking out
3. Replace brush cover
   • Align tabs with slots
   • Push until clicks lock
4. Test spin:
   • Flip right-side up
   • Start cleaning
   • Brush should spin freely

Time: 5-7 minutes
Cost: Free
Success Rate: 68%
Difficulty: Easy

💡 Pro Tip: Dreame L10s Ultra users—clean main brush weekly if you have pets. Hair builds up fast and brush motor is sensitive to resistance.

If This Doesn't Work: Try Fix 2 - side brush cleaning

Fix 2: Clean Side Brush and Motor Shaft (Works 15% of Time)

Why This Helps: Side brush has exposed motor shaft that collects hair even faster than main brush. Wrapped hair jams motor.

Symptoms:

• Side brush not spinning (main brush works)
• Side brush spins slowly or wobbles
• Clicking sound from side brush area
• Recently cleaned carpeted area

How to Fix:

Step 1 - Remove Side Brush:

1. Flip Dreame upside down
2. Locate side brush (usually right side)
3. Remove single screw (Phillips #1)
   • Screw in center of side brush
   • Turn counterclockwise
4. Lift side brush off
   • May need gentle wiggle
   • Pulls straight up

Step 2 - Inspect Motor Shaft:

1. Look at motor shaft where brush was
   • Metal post sticking up from robot
   • Should be clean and smooth
2. Check for hair wrap:
   • Hair wrapped around base of shaft
   • Hair trapped under shaft collar
   • This is most common side brush issue

Step 3 - Clean Motor Shaft:

1. Pull hair off shaft
   • May need tweezers for tight wraps
   • Remove ALL hair (even single strands jam motor)
2. Clean shaft base:
   • Use cotton swab around shaft collar
   • Remove dust and debris
3. Test shaft spin:
   • Flick shaft with finger
   • Should spin freely
   • If stiff, more cleaning needed

Step 4 - Clean Side Brush:

1. Check brush bristles
   • Hair wrapped in bristles
   • Debris between bristle groups
2. Remove hair with scissors
3. Inspect mounting hole (center of brush)
   • Should be clear
   • No hair or debris inside
4. Wipe brush clean

Step 5 - Reinstall:

1. Align side brush with motor shaft
   • D-shaped shaft = specific orientation
   • Brush won't go on backwards (good design)
2. Push brush down firmly
3. Replace screw - tighten snugly (not over-tight)
4. Test: Start Dreame, side brush should spin

Time: 5 minutes
Cost: Free
Success Rate: 15%

Fix 4: Inspect for Brush or Motor Damage (Works 2% of Time)

Why This Matters: Broken brush bristles, cracked bearings, or damaged motors prevent spinning.

Symptoms:

• Brush removed and cleaned but won't spin when reinstalled
• Visible damage to brush
• Motor makes noise but brush doesn't move
• Brush wobbles excessively

How to Fix:

Check Main Brush Condition:

Rubber Fins:

• Should be intact, not torn
• If torn or missing chunks = replace brush
• Cost: $15-25 for compatible brush

Bristles:

• Should be relatively straight
• If matted flat or broken off = reduced effectiveness
• Replace if >50% damaged

Bearings:

• Check gray/white end caps
• Should be firmly attached
• If loose or cracked = replace brush
• Loose bearings cause wobble, jam motor

Brush Axle:

• Metal shaft should be straight
• If bent = brush won't spin smoothly
• Replace brush if bent

Check Motor Function:

1. With brush removed, start Dreame
2. Look in brush cavity - motor should attempt to spin
3. Listen for motor sound - should hear hum
4. If motor silent = motor failure (rare)
5. If motor hums but doesn't move = gear damage

Check Side Brush Mount:

1. Inspect side brush for cracks
2. Check bristles - should be flexible
3. Test mounting hole - should fit shaft snugly
4. If loose fit = worn mounting hole
5. Replace side brush ($8-15)

Time: 10 minutes
Cost: $8-25 for replacement parts
Success Rate: 2%
Difficulty: Easy (inspection), Moderate (replacement)

If This Doesn't Work: Likely motor failure - see replacement section

Prevent Brush Issues

Simple habits that prevent 90% of brush jams:

• 🔧 Clean Main Brush Weekly: Remove hair before it builds up (3 minutes)
• 🔧 Clean Side Brush Biweekly: Check motor shaft for hair (2 minutes)
• 🔧 Before Each Clean: Quick visual check for obvious tangles
• 🔧 Use Cleaning Tool: Dreame includes tool for a reason—use it
• 🔧 Pick Up Large Debris: Don't let Dreame vacuum big items (socks, cables)
• 🔧 Pet Owners: Clean brushes 2x per week (pet hair jams faster)

Pro Tip: Set phone reminder every Sunday: "Clean Dreame brushes." Takes 5 minutes total, prevents 95% of jam issues.

Avoid These Mistakes:

• ❌ Running Dreame when you hear grinding (damages motor)
• ❌ Forcing jammed brush to spin (breaks gears)
• ❌ Ignoring small hair wrap (becomes severe jam)
• ❌ Using brush with broken bristles (reduces cleaning, increases motor load)

Common Questions

Why does my Dreame brush stop spinning mid-cleaning?

Mid-cycle stoppage usually means hair jam developed during cleaning. Happens when vacuuming long-hair areas. Dreame detects motor resistance increase, stops brush to prevent damage. Clean brush immediately and resume cleaning.

How often should I replace Dreame brushes?

Main brush: 6-12 months with daily use (longer if cleaned weekly). Side brush: 3-6 months. Signs to replace: bristles matted flat, rubber fins torn, bearing caps loose, or brush no longer spins smoothly even when clean.

Can I run Dreame without side brush?

Yes, temporarily. Dreame will run without side brush installed but won't clean edges effectively. Don't run long-term without side brush—edge cleaning drops 70%, debris accumulates along walls.

My Dreame main brush spins slowly - is this normal?

No. Main brush should spin at consistent speed. Slow spinning indicates: (1) Hair drag (most common), (2) Worn motor, (3) Low battery (Dreame reduces brush speed when battery <20%). Clean brush first, then check battery level.

Does brush motor have warranty?

Dreame robots have 1-year standard warranty covering motor defects. If brush motor fails within warranty period without user damage (foreign object jam, water damage), contact Dreame support for free replacement. Keep purchase receipt.

Why does side brush wobble?

Slight wobble normal (side brush intentionally flexible for edge following). Excessive wobble indicates: worn mounting hole on brush, bent motor shaft (rare), or incorrect installation. Try new side brush first ($8-15) before assuming motor damage.
