Last chance on Prime Day iRobot deals, including a 2-in-1 Roomba for over 40% off

This streamlined model is beloved for its ability to get the job done quickly, quietly and effectively. It's compact (only 3.1 inches high) for shimmying under shallow areas, offers three levels of suction and maps out carpet and hardwood floors in neat rows to ensure it doesn't miss a beat. 

Control it using Alexa voice commands or the iRobot app and let it do its thing. After 120 minutes worth of cleaning, it will return to its dock for charging. 

"I'm a professional cleaner, so I have high expectations and so far this has met my needs," said one fan. "It has some 'sweeper legs' that get in corners or edges like under counters and sometimes it does miss stuff, but I know it's working as I have to empty the dirt bin frequently ... I set mine to go off at 12 p.m. every day and like clockwork, Dusty comes out and goes to work!"

For a deeper clean, consider this multitasker, which offers the same hands-free commands, smart navigation, run time and auto-charging feature as the Q0120, plus mopping capabilities. 

According to the brand, the washable microfiber mop pad is good for up to 30 sessions — that's a lot less grunt work and mop wringing for you. The clincher: Right now, you can save $230 (that's 43%).

"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 what some other reviews have said, I don't think she makes that much noise. I can watch TV with her running."

The i3+ Evo operates in the same fashion as the Roombas above, but with more attention to detail: It's designed with dirt-detection technology that homes in on grittier areas that may not be as obvious to the naked eye, giving them two passes to ensure nothing gets by. It has a battery life of 75 minutes, and 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. At only $290, it's at the lowest price we've ever seen. It's nearly 50% off!

"A master class in refinement," said a devotee. "Not only does the i3 smartly navigate the home, but it is much more gentle on your furniture. It deftly figured out how to navigate the maze of table legs underneath my kitchen table, and it no longer attempts to leap over the stabilizing arm of my coffee table, like Bigfoot crushing a row of cars. It also seems to better cope with 'low clearance' issues. It seems more cautious when entering tight fits and less likely to get stuck. Even the fit and finish ... is a cut above. The textured plastic on the top looks like a cloth finish and is resistant to fingerprints. 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."

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. 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 floor-cleaning shop. The clincher: an impressive $270 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. "You'd be surprised the places these strands can end up. However, because they're so long and thick, they're death for vacuums, and I've grown up constantly cutting hair out of the bottoms of my heavy vacuums while dust pours out, a gross process. Roomba solved this! Yes, we do have to take him apart every now and again and we do have to cut some hair loose from the rotators; but the parts are totally built for this! 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 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. I haven't had to buy any replacement parts, though they're cheap if we need them!"
