Life’s too short to vacuum every other day, but luckily, you can pawn that tedious chore off to a Roomba, and the entry level 652 model is marked down to $250 today on Amazon, which is the best price we’ve seen on any Roomba ever.
From what I can tell, this is basically identical to the entry-level Roomba 650, but with a Lithium Ion battery included, rather than nickel-metal hydride, which should enjoy a longer lifespan and provide fade-free power to the vacuum.
