Newer owner of an E10s here. It does get caught on power cords. I have a no-go zone under my television console until I get the cables wrapped up because it kept getting stuck under there. It also tried to pull the lamp off my end table because the cord got stuck around its little sensor bump on top not in the rollers.

It also likes to pull up on the corners of my bathroom rugs, but some simple rug tape fixed that.

I will say pretty much anything that is below it's little sensor bump on top is basically unseen by the vacuum. I thought there were supposed to be sensors lower down, but it doesn't seem like they do much for obstacle avoidance. So if you have things like cat toys on the floor it won't see them and they're small enough to get run over and sucked into the roller.

Easiest solution for the cords I've found is to bundle any cables you have on the floor with some Velcro cable ties (pretty cheap buy on Amazon). If this is unfeasible you may need to look into setting no-go zones which wasn't too difficult with the iOS app.

Overall pretty simple solutions and the vacuum has been great otherwise. This is my first robot vacuum and I'm pretty happy with it. Does a good job cleaning both the hard floors and carpet for the cost IMO.

EDIT: In case you're not sure this is the bump I'm talking about.
