So a month back or so, my CO (carbon monoxide) detector went off. At first I thought it was a fluke, but it was periodical, meaning it would beep for half a minute then stop, and start beeping again a minute later. So I opened all the windows around me, but it still didn’t stop beeping. Finally I got pissed at it and moved it to another location. The beeping stopped. That led me to think there was something in the bathroom coming out that was triggering it. Anyways, I didn’t worry much about it.
A couple weeks ago, I moved the detector back since what good is a detector if I’m just going to put it in some random corner. It went fine for awhile, but started beeping again last week. At first, I was confuzzled, but then I noticed my Roomba was vacuuming the floor at the same time, so I started connecting the dots. The CO detector has this feature where you can test it by using your remote control. My Roomba has these virtual walls that also emit infrared signals.
So I took my virtual wall and aimed directly at it and the beeping went crazy. I turned off my virtual wall and the beeping stopped completely. Guess we found the culprit. Anyways, I didn’t need that virtual wall there. Turns out my Roomba has stairway detection so it won’t fall down the stairs.
Forgot to mention the fact that it went off last week was due to the fact I increased the power of the virtual wall. The virtual wall has 3 settings: 3′, 4′-7′ and 8’+ walls. I had increased the virtual wall from 3′ to 8’+ because I was working from home and didn’t want the Roomba to enter my little office.
