Dust bunnies
If you’re trying out a new skill, then it usually pays to familiarise yourself with the tools needed and how they work. The same would be a good idea if you’ve decided that this is the day you’re going to vacuum for the first time. Otherwise, you could end up with the same dusty feet as this guy.

Granted, putting the empty button next to the on button is a pretty clear design fault, especially when you’re dealing with cleaning newbies. If this guy ever does get over his vacuum trauma and decide to help out with the cleaning again, he’d better stand over the bin before he presses anything.
