Score Roomba for a record-low 50% off — and more Prime Day steals from iRobot

The i3+ Evo employs the Roombas' signature technology, but brings even more attention to detail: It's designed with dirt-detection software that zeros in on grittier areas that may not be visible to the naked eye, giving them two passes to ensure nothing remains behind. 

It has a battery life of 75 minutes, plus smart sensors keep it from bumping into furniture and falling down the stairs. And — here's where it gets really neat — it empties its own bin for up to 60 days. 

"A master class in refinement," said one well-spoken devotee. "Not only does the i3+ Evo smartly navigate the home, but it's much more gentle on your furniture. It deftly figured out how to navigate the maze of table legs underneath my kitchen table ... The dirt bin has been redesigned to be rinsed so that it can be more easily cleaned. The i3 has higher suction while actually producing less noise. The rollers are also easier to clean of pet hair."

At only $250, down from $441, it's edging the lowest price we've seen on record (off by $1).

Last, but certainly not least, the i3+ Vacuum and Mop offers the best of both — make that all — worlds with convenient app and voice control, orderly navigation, spot cleaning, powerful suction and edge-sweeping, self-charging and self-emptying capabilities. 

But wait, it gets better: You can also upgrade from an all-surface vacuum to a vacuum/mop duo with the switch of a bin: It's like a one-stop shop for all of your floor-cleaning needs! And during Amazon's October Prime Day deal event, you can rake in more than $130 in savings.

"Anyone who has very long and thick hair or who lives with us knows that long strands of hair end up absolutely everywhere," said a shopper. "Everything comes apart in such a sensible way, including inside the rotator tubes where hair sometimes spirals; all of these pieces very easily come apart then come back together so you can regularly clear out that long hair with zero issue, maybe one scissor snip, not a dusty mess, it's so easy. ... I was pleasantly surprised how perfectly it knows how to handle it, and our guy is going strong after a year."

Hate vacuuming? Get a robot to do it for you. The new Roomba Essential is on sale for its lowest price ever! Some highlights: It cleans in neat rows thanks to Smart Navigation features. (Think more precision, less bumper cars.) You'll get up to two hours of cleaning on a single charge, and if it isn't done when the charge runs out, it will pick up where it left off after some rest. And it can go just about anywhere: Use it on carpet, tile or hardwood floors. 

This little robovac has over 19,000 five-star reviews on Amazon. "Love the job this Roomba does," said one reviewer. "I was shocked at how much dust/debris it picked up in a room I thought was clean. Charging is easy, cleaning is relatively easy, and the machine is relatively quiet compared to a regular vacuum."

"Our floors are much cleaner now that we run this machine every few days," said another. "Because we have it, we are mindful of cords, cat toys and other items on the floor that could tangle it up, so its presence also kind of enforces a level of tidiness."

For a deeper clean, consider this multitasker, which offers the same hands-free commands, smart navigation, run time and auto-charging feature as iRobot’s essential robot vac, plus mopping capabilities. According to the brand, the washable microfiber mop pad is good for up to 30 sessions. Floors that glisten (sans the typical grunt work and mop wringing) for $85 off? We're sold.

"Could not be more pleased. I still run the regular vacuum periodically, but Rosie (named after the Jetsons' robotic housekeeper) does an amazing job," said a buyer. "She gets under the beds where I cannot reach, which is important because I have an indoor cat. I do have to remember to pick up the food and water bowls, as well as any cords lying on the floor, but then I watch her work. Unlike some other reviews, I do not think she makes that much noise, I can watch TV with her running."
