Here in my country we say: don't look a gift horse in the mouth, hehe, it's a joke. I think for costing $14 it doesn't include so many functions, a random movement and the type of battery it uses already says a lot. Maybe it's more useful for spaces without obstacles and little traffic of people.
lol, we actually say similar things around here, I just needed to poke at it a bit. Plus the gifter won't ever find this so whatever haha.
Yeah, it'll be better in a bigger place with few obstacles, but I just feel there's a lot better things to be gotten with that money, and even if I must get a smart sweeper it has to be a better one.
