I have a new Roomba 570 that is afraid of falling into a black carpet. In other words its ‘cliff sensors’ indicate a cliff when on black carpets such as a door matt or Ikea style carpets with bold geometric black patterns. This a real pain since it constantly gets stuck and t…

I should just add that the IRobot Roomba is a great appliance. I wouldn’t want to do without it, even with its flaws. If you find that appliances such as dish washers and washing machines are useful to you, then you will get satisfaction out of owning the IRobot Roomba. hope …

I am a bit upset. I have just spent $25,000.00 (does not include equiptment) to build a nice Media room. My thoughts were TO DO IT RIGHT…I must make it BLACK. So the walls are black (pool table felt) and short nap black marine carpet. Of course you knew BEFORE you read this that …

After I wrote yesterday that I was upset…I went to brain storming and I came with a TESTED way to make the unit think the carpet is NOT black. I have tired the foil and the white papaer. It works sometime and other times it does not…plus U disable your unit form seeing a drop off…

@edleblanc1 It has been about 14 months since your post and, assuming iRobot isn’t interested in your solution and your aren’t commercializing it otherwise, would you be willing to share the concept? I have a new Roomba 650 and it refuses to clean the black-grey-white patterned …

It has been around 4 months since your post and, expecting iRobot isn’t occupied with your answer and your aren’t commercializing it overall, would you be willing to impart the idea? I have another Roomba 650 and it declines to clean the dark dim white designed cover in the loung…

It seems to me that part of the problem with covering the cliff sensors with paper or foil is lack of space for the infrared light to reflect and be received on the other side. I solved this by creating a reflecting surface with a mm or 2 of space between it and the sensor windo…

I had a similar problem, involving the Braava and a concrete floor, which is grey but apparently too dark for the edge sensors. I was able to solve the problem with aluminum foil and electric tape. I had mixed/bad luck with smooth pieces of foil cleanly taped over the sensors; c…

I use a Eufy 11+. It can’t navigate the black swirls on our many rugs. I used black electrical tape to secure 3 carefully cut and folded pieces of manila folder between the bumper and and the body of the robot covering, but not touching the 3 sensors. The results are excellent…

Why not make the checking of the sensors a choice in the app? Seems like a simple software change in the app and an updated version for the Roomba.

We unfortunately have not heard from @edleblanc1 and nothing has been commercialized yet to fix this issue. If you feel comfortable, you may open up your robot and tape the receiver and transmitter together for each sensor. As shown in this blog.
