This design is different from others. Most consist of a continuous ring that interferes with the Roomba's sensor. This design is similar to a fence, so only small areas of the sensor field are covered. This allows the Roomba to do its job without interference. There are two mounting options depending on the existing obstacles in the home: One complete and one partial. Both have proven themselves very well in practice. The complete version also detects smaller obstacles when the Roomba drives directly to them. I attached the bumpers with double sided tape.
