🔍 Why Robot Vacuums Get Stuck on Thresholds

5 Common Causes:

1. Threshold Too High (40%): Exceeds robot's max climb height
2. Dirty/Stuck Wheels (30%): Reduced traction and power
3. Approach Angle (15%): Robot hits threshold at wrong angle
4. Low Battery (10%): Not enough power to climb
5. Wheel Wear (5%): Worn tires lose grip

Maximum Climb Heights by Brand:

💡 Measurement Tip: Measure your threshold height with a ruler. If it's above your robot's max climb, you'll need ramp assistance.

🔧 Fix #1: Clean All Wheels

Success Rate: 40% | ⏱️ Time: 5 minutes | 💰 Cost: $0

Dirty wheels are the #1 cause of threshold problems.

How to Deep Clean Wheels:

All Brands (Similar Process):

1. Flip robot upside down on soft surface
2. Clean drive wheels (2 large side wheels):
   • Remove ALL hair wrapped around axles
   • Use scissors to cut through hair bundles
   • Wipe tire surface with damp cloth
   • Spin wheel - should rotate freely
3. Clean caster/swivel wheel (front wheel):
   • Pull straight out (some models require unscrewing)
   • Remove every strand of hair from axle
   • Wipe wheel and cavity clean
   • Ensure wheel spins AND swivels freely
   • Reinstall firmly
4. Test traction:
   • Place robot on threshold manually
   • Wheels should grip, not slip

✅ Success Sign: Wheels spin freely with no resistance

💡 Pro Tip: Clean wheels after EVERY 3 cleanings if you have pets or long hair.

🔧 Fix #2: Optimize Approach Angle

Success Rate: 25% | ⏱️ Time: 10 minutes | 💰 Cost: $0

Robots climb best when approaching thresholds head-on (perpendicular).

How to Improve Approach:

For Mapping Robots (Roomba i/j/s, Roborock, Neato):

1. Edit virtual map in app
2. Create no-go zones that force perpendicular approach:
   • Block diagonal paths to threshold
   • Leave only straight-on approach open
3. Use zones/rooms to control cleaning order
4. Test multiple cleanings to verify consistent approach

For Random Navigation (older Roomba, budget Eufy):

1. Place furniture strategically:
   • Create a "funnel" leading to threshold
   • Force robot to approach straight-on
2. Use magnetic strips (if robot supports):
   • Guide robot path to threshold
   • Block diagonal approaches

💡 Physics: A 45-degree approach doubles the effective height. Straight-on is always better.

❓ Frequently Asked Questions

Q: Can robot vacuums climb over 1-inch thresholds?

A: Most cannot. Maximum climb for most robots is 0.6-0.8 inches. For 1-inch thresholds, you MUST use ramps.

Q: Why does my robot cross some thresholds but not others?

A: Approach angle and battery level. The same threshold may be crossable when approached straight-on at 80% battery, but impossible at 45-degree angle with 30% battery.

Q: Will threshold ramps be a tripping hazard?

A: Low-profile ramps (under 0.5 inch) are generally safe. Place bright tape on edges for visibility, or use transition strips that mount flush.

Q: My robot used to cross thresholds fine, now it gets stuck. Why?

A: Dirty wheels or wheel wear. Clean wheels thoroughly. If tires are smooth/shiny, they may need replacement ($15-35 per wheel).

Q: Can I train my robot to cross thresholds better?

A: No, but you can optimize conditions: Clean wheels, ensure full battery, use max power mode, and force perpendicular approach with virtual barriers.

Q: Do robot vacuums learn threshold locations over time?

A: Yes, if they have mapping. Smart models (Roomba i/j/s, Roborock S series, Neato D series) remember where thresholds are and can adjust approach angles.

Q: Should I carry my robot over thresholds manually?

A: Only as a temporary solution. This defeats the purpose of automation. Install ramps or virtual barriers for long-term fix.

Q: Can thick carpets cause threshold-like problems?

A: Yes. High-pile carpet edges act like thresholds. Use carpet mode (if available) or place tape to create gradual transition.
