the robot keeps getting stuck under my couch, it goes in but then just spins its wheels.

Diagnosis

The issue occurs because the Samsung Bespoke Jet Bot Combo AI possesses a chassis height that is nearly identical to the clearance of many modern couch frames. When the LiDAR sensor detects a gap, the robot attempts to enter; however, once inside, the top-mounted LiDAR turret or the chassis's upper edge makes physical contact with the underside of the furniture. This creates a "pinch point" where the robot is physically wedged, but not enough to trigger a hard collision sensor. Because the robot is stuck, the drive wheels lose traction on the floor, causing the "spinning wheels" behavior. The AI navigation system detects that it is not moving despite the motors running, which triggers a recovery loop. The robot will spin in place attempting to find an exit path, but because the friction from the couch frame is holding it in place, it cannot execute the reverse maneuver required to escape. You can confirm this by checking the SmartThings app for a "Stuck" or "Unable to move" notification, or by noticing the robot is centered exactly under the lowest hanging rail of your sofa.

How to Fix It

To permanently prevent the robot from entering the "danger zone" under your couch, you must implement a digital perimeter using the SmartThings ecosystem. Follow these precise steps:

1. Open the SmartThings App on your mobile device and select your Bespoke Jet Bot Combo.
2. Navigate to the Map view. Ensure you have already completed a full "Home Mapping" run so the app has a precise layout of your living room.
3. Tap on the No-Go Zone icon (usually located in the bottom menu or under the 'Map Settings' gear icon).
4. Select Add Zone. Instead of a broad square, use the drag-and-drop handles to create a narrow rectangular strip exactly where the couch's under-clearance begins.
5. Ensure the zone extends at least 2 inches beyond the actual edge of the couch to account for the robot's turning radius and sensor buffer.
6. Tap Save or Apply. The map will now show a shaded red or grey area. The AI will now treat this area as a solid wall and will not attempt to enter the gap, regardless of what the LiDAR sees.

If That Didn't Work

• Adjust Object Recognition Sensitivity: If the robot is still trying to "peek" into the zone and getting snagged, go to Settings > Robot Settings > Object Recognition. Change the sensitivity from 'Medium' to 'High'. This forces the AI to be more cautious around low-profile obstacles, making it more likely to avoid the couch entirely.
• Physical Furniture Risers: If you actually want the robot to clean under the couch, the clearance is likely less than 4.5 inches. Install heavy-duty rubber or plastic furniture risers (available in 1-inch or 2-inch increments) under the couch legs. This provides the necessary overhead clearance for the LiDAR turret to rotate without friction.
• Physical Barriers: If the software zones are glitching due to poor Wi-Fi signal in that specific corner, place a discreet physical object (like a decorative floor plant or a weighted doorstop) at the entry point of the couch's under-area. The Bespoke Jet's 3D sensors will detect the object and steer clear.
• Reset Mapping Data: If the robot is ignoring No-Go Zones, the internal map may be corrupted. Go to Map Settings > Delete Map and run a fresh mapping cycle. Ensure all doors are open and the floor is clear of small debris to ensure the most accurate spatial coordinates.

Heads Up

• Avoid Magnetic Strips: Do not waste money on third-party magnetic boundary strips. The Bespoke Jet Bot Combo relies on LiDAR and AI vision; it does not have a magnetic strip sensor and will drive right over them.
• Check the LiDAR Turret: Periodically wipe the top LiDAR sensor with a dry microfiber cloth. Dust buildup on the rotating sensor can cause "ghost" obstacles or a failure to recognize the boundaries of your No-Go Zones.
• Avoid "Dark" Under-Couch Areas: If your couch is extremely deep and dark, the AI vision sensors may struggle to distinguish the floor from the furniture frame, increasing the likelihood of the robot attempting to "explore" the void.
