bObi uses infrared light to detect stairs or edges in your home. Because dark carpeting tends to absorb infrared light, it can sometimes seem like an edge to bObi.
If bObi continually displays ER 01 on her remote while she is working on dark carpeting, you may need to blindfold her.
Flip bObi over onto a flat surface. bObi's 4 edge sensors (highlighted in red) are located on her underside.
Use the blindfold stickers that came in bObi's box to blindfold her sensors. Peel off the plastic covering on one side of bObi's blindfold stickers and place them onto each of bObi's 4 edge sensors.
Make sure each sensor is fully covered. Remember, while bObi is blindfolded, she will not be able to detect stairs or edges!
