Roomba 620 vs. 761

The odds are you’ve already aware of the existence of robotic vacuum cleaners. Usually, such appliances come at a really high price tag. However, there are still some alternatives in the marketplace that offer good value for the money. We’re going to talk about two products that fit into this category – namely the Roomba 620 and the Roomba 761.
