Roomba Dark Rug Issue

Debris on the roombas sensors underneath the unit.

Roomba dark rug issue. If your robot is having issues navigating on dark surfaces please ensure there is no dust or debris blocking the cliff. I have two roomba discoveries and niether one of them would roll over black color lines in any of my area rugs. Yes even the top of the line roomba 980 is plagued by this problem. Basically you need to trick the 4 sensors on the front of the machine as a dark area rug will trick the roomba in thinking it is falling down the stairs.

This is a common issue with the roomba 650. Roomba avoids black color pattern on rugs. Then cut into 4 small pieces that will cover the sensors. Later roomba models have rubber rollers that are much better at not getting stuck.

Bad or no continuity of the roombas sensors located on the bottom of the 650 finally and most likely the docking station pins are not operating correctly. Roomba 960 and 980 need light. I had a working s9 for 2 months before it broke and after troubleshooting over the phone 3 different times was. For the last point the issue is inside the docking station.

Therefore when the roomba rolls over a black dark carpet or border it interrupts the absence of reflected infrared light as a cliff. But a roomba s problems with rugs does not stop there. I contacted irobot customer support. It could the result of.

Tape them in place over the sensors on the. Dark colors absorb light and light colors reflect it. They use dual beam cliff sensor technology which improves their ability to clean over dark surfaces while also being able to detect cliffs or edges. Your roomba will act confused and start going back and forth as it tries to get away from the black or very dark carpet in order to keep itself from danger.

Roomba does not go well with black or dark patterns on carpet. This is a safety mechanism included in all roomba models. They would stop at the edge of the black and change direction as if they detected a step or ledge. I discuss two other rug issues in later sections.

All irobot roomba models have this issue. I am now on my 5th defective roomba s7 and s9. And also earlier roomba models such as the 400 and 600 series had bristle rollers and the bristles got caught on the carpet fibres. Roomba i series and s series robot vacuums can navigate on dark surfaces.
