Roomba is like a little robot that cleans your floors for you, and there are many different kinds!
Some Roombas have a special box that empties itself so you don't have to, and some can even mop the floors too.
The Roombas with letters and numbers like 'j9+' are the smartest, while the ones with just numbers are simpler.
You can choose the Roomba that has the right features for your home, like how smart it is or if it can avoid small things.
