Deals Week is the best time of the year to buy a Roomba, and four different models are down to all-time low prices for the occasion today.

The entry-level Roomba 652 doesn’t have too many bells or whistles, but it’s still an excellent little vacuum that cleans well, and is good at finding its way back to its charger, in my experience, even if it looks a little stupid ping-ponging around your house.

For $25 more, you can upgrade to the Roomba 690, which is basically identical to the 652 in use, but with the addition of Wi-Fi so you can control and schedule it from your phone, or even with your voice via an Amazon Echo.

Newly added today is the 860, which does not have Wi-Fi, but claims five times the suction of the 600 line, and easier-to-clean brushes. $350 is an all-time low, and $150 less than usual.

And on the high end, the 980 is even more powerful than the 860, and includes a suite of advanced sensors that map your house to help it clean more efficiently, and let you know which rooms still need attention. $799's a lot of money, but it’s $100 less than usual, and an all-time low.
