Dobby: Bumper Stuck

My pet Roomba, Dobby, got a thread wrapped around his constantly rotating whisk brush. Soon after that, a carpet loop got wrapped in there, too.

There’s poor ol’ Dobby, looking like he got stuck for no reason again. I’m really not sure if the thread aided him picking up a loop of carpet or not. You can be the judge. Here’s a view of the whisking broom with thread wrapped around it. The paler fuzz is the remnant of the carpet thread after I freed Dobby.

The loop of carpet prevented Dobby from moving in any direction. The robot voice insisted that Dobby had a “stuck bumper”, and I needed to tap on it a few times to clear whatever was sticking it. “The App” also claimed Dobby was experiencing a stuck bumper.

I just realized that iRobot (the corporation) has a “Vitruvian Roomba” depicted in The App when Dobby gets stuck.

Here’s all the thread I extracted from Dobby’s whisking brush:

It’s possible that black thread had been wrapped around his whisk for a while. Dobby is not a marine predator and is therefore not countershaded, which makes visual detection of black thread almost impossible
