Why Does My Roborock S8 MaxV Ultra Keep Running Into Obstacles?
- Obstacle avoidance sensitivity set too low
- Camera lenses dirty blocking AI vision
- Lighting too dim for camera-based detection
Problem Description
Your Roborock S8 MaxV Ultra has advanced obstacle avoidance with cameras and AI but it keeps running into objects and pushing things around. Cables get tangled, pet bowls get pushed, and toys get run over. The reactive AI is supposed to see and avoid these obstacles but it fails constantly. This expensive vacuum should do better.
Symptoms
- Vacuum pushes pet food and water bowls
- Power cables and cords get tangled in brushes
- Small toys and socks get eaten by vacuum
- Vacuum bumps into furniture legs repeatedly
- Dark colored objects not detected and hit
- AI avoidance worked initially but degraded over time
Recognize these? Here's what usually causes it.
Common Causes
- Obstacle avoidance sensitivity set too low
- Camera lenses dirty blocking AI vision
- Lighting too dim for camera-based detection
- Object recognition turned off in settings
- Firmware needs update for improved detection
- Obstacles too small for current AI capabilities
Most fixes happen in the first 3 steps.
No obstacle avoidance is perfect. Keep valuable fragile items off the floor regardless of AI capabilities.

Step-by-Step Solution
Maximize Obstacle Avoidance Sensitivity
Open the Roborock app and go to your S8 MaxV Ultra settings. Find Obstacle Avoidance and set sensitivity to maximum. Lower settings allow the vacuum to clean closer to objects but increase collisions. Maximum sensitivity keeps the vacuum further from detected obstacles even if it means missing some edge cleaning.

The S8 MaxV Ultra uses front and side cameras for obstacle detection. Dust on lenses severely degrades detection. Use a soft dry microfiber cloth to clean all camera lenses on the front of the vacuum. Do this weekly or more often if you have pets. Dirty lenses are the most common cause of detection failures.
Check Room Lighting
Camera-based obstacle avoidance requires adequate lighting. In dark rooms the cameras cannot see obstacles clearly. If your vacuum runs at night or in dim rooms it will hit more objects. Schedule cleaning during daylight or turn on lights before cleaning starts. The vacuum works best in normally lit rooms.
Enable All Object Categories
In the app go to Obstacle Avoidance settings and make sure all object types are enabled for detection. Categories include cables, shoes, pet waste, fabric, and more. If any category is disabled the vacuum will not avoid those objects. Enable everything for maximum protection.
Create No-Go Zones
Some obstacles are too challenging for any AI. Pet bowls with reflective water surfaces and thin black cables are difficult to detect. In the app tap your map and create no-go zones around these permanent obstacles. The vacuum will never enter these zones eliminating the problem entirely.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
The AI learns over time. When it hits something it should not have take a photo in the app to help train the recognition model.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
- Obstacle avoidance sensitivity set too low
- Camera lenses dirty blocking AI vision
- Lighting too dim for camera-based detection
- Object recognition turned off in settings
- Firmware needs update for improved detection
