These Roombas are the lowest price they’ve ever been on Amazon — and one is almost 50 percent off.

Save up to 42%: The Roomba J7 and J7+ from iRobot are on sale at their lowest prices ever on Amazon right now.

Amazon’s acquisition of iRobot brings with it a lot of confusion regarding privacy, but it also brings about deals like we’ve never seen before. And considering now is the time when homes can be messier than ever (thank you so much, surprise house guests and kids all home for the holidays), having a Roomba to do all the dirty work for you is pretty much the ideal scenario. And thankfully, there’s never been a better time to buy.

As of Nov. 1, popular Roomba models the J7 and J7+ are on sale on Amazon at their lowest prices ever, for savings of up to 42%. Normally, the J7 comes in at almost $600 versus its current $349 price tag, while the J7+ is now $599, as opposed to its regular price of $799.99. That means you get one for 42% off, and the other for 25% off. A pretty sweet deal, right?

Let’s also make one thing pretty clear: These are not your standard, bottom-of-the-line Roombas. The J7 is definitely the lower model, but it comes complete with a powerful, three-stage cleaning system, Smart Map technology to avoid objects in its path, and can also create customized cleaning schedules for you based on your habits.

The J7+, on the other hand, is even more high-tech, featuring self-emptying technology, as well as Genius Technology and PrecisionVision Navigation to avoid small obstacles that you’d previously have to pick up before starting vacuuming, like phone chargers and pet waste. Long story short? You don’t even need to pre-clean, making this literally the most low-maintenance option available. So even though it might be a little more expensive, we’d say the peace of mind you get is well worth it.

If you’re looking to finally take the plunge into the wild and wacky world of Roombas, we’d say this is the best time to buy: You get high-end options for budget prices. Still, these deals won’t last forever.
