Flies are quick and annoying and very difficult to deal with. The standard flyswatter requires a lot of energy and skill.
This carnivorous clock actually waits for dinner to arrive on a silver platter (or the little sticky belt). This robot is quite the hunter.
The idea is that different pests will be browsing around your living area and they may land on the clocks sticky belt. The belt will then roll the bugs into a chemical vat. The reaction causes fuel for the clock to run.
