It was at the Las Vegas Convention Center at CES earlier this year we first encountered the white Yves Behar designed Mint prototype, merrily sweeping up dust and dirt purposely spilled by the Mint staff, impressing a curious crowd with its friendly design and navigation system. In a growing field of robotic technology cleaners, the Mint was aiming to differentiate from the competition, simplifying the interface, and offering a "less is more" experience for household floor cleaning duties. Now it was time to see how it would do in a real-world setting...
The top control panel is all you'll really need to learn how to use. Turn it on, alongside the Northstar Navigation Cube, choose from dry or wet surface cleaning and let the Mint do its thing.
The design philosophy of Evolution Robotics's Mint versus the popular iRobot Roomba is similar to the philosophical differences between Apple and Google's offerings: one aims to simplify features, while the other aims to incorporate as many as possible. The physical design magnifies the comparison further, with the Mint looking arguably like something Apple might offer if they jumped into the cleaning appliance market. Nowhere is this more evident than the top control panel of the Mint, where just three icon-labeled buttons are offered with nothing else by the Mint branding tastefully on a corner.
After charging the unit overnight (sort of a bummer for an impatient type like ourselves who wanted to get cleaning right away), we positioned the Northstar Navigation cube onto our living room coffee table, turned on the Mint (a friendly chime welcomes and alerts you it is on) after adding a dry sweeping cloth, and then watched as it journeyed across our living room like the cleaning droid of our dreams.
Choose between a wet or dry cloth pad. Swiffer disposable pads can also be used, but we liked the eco-friendly reusable inserts best.
It should be noted the Mint isn't a vacuum like iRobot's units. The Mint uses reusable or disposable Swiffer-style cloths to pick up lighter debris and pet hair onto the cleaning cloths. Hardwood floor owners and people with pets will specifically benefit from having the cleaning services of the Mint to fill-in inbetween more serious vacuuming sessions; the amount of debris picked up during a single cleaning session was actually surprising, since we think of ourselves as atypically fond of vacuuming. Thanks to the low profile, oversized modernist Chiclet gum design, the Mint easily gets under furnishings where we obviously forgot to vacuum or sweep. Our cats also seemed to find the unit to their amusement.
The Mint performed well at cleaning up our hardwood floors of small sized debris, pushing and catching them onto the cleaning cloth.
For the most part, the Mint was able to navigate furnishings without issue, though one tight spot left it stuck and stranded
Another way the Mint differs from the competition is its Northstar Navigation system. The GPS-based system is derived from the same tech inside those Sony Aibo robotic canines that were all the rage years back. The nav system directs the Mint to sweep across as much surface area as possible without too much overlap, utilizing proximity and directional sensors in the unit orchestrated by infrared lights sent up and bounced back from the base unit down to the Mint. If you've got stairs, no need to worry. The Mint has an edge detection unit which prevents it from taking a suicidal leap.

The Mint also does a decent job of cleaning kitchen floors with the wet cloth.
Although the Mint is not engineered to clean carpet, it did traverse across some low pile FLOR carpet tiles, revealing itself to be capable of handling less-than-ideal surfaces. The two times the Mint found itself in trouble was while navigating inbetween a wall and the home office task chair, and also later finding itself wedged underneath a stove (we found out only after noticing we didn't hear its motors from the other room, and we ran to its aid like a worried pet owner with a new pup). The unit can sometimes drift over to other unintended rooms, since the nav system does not limit it to specific boundaries. Each situation magnifies robotic navigation is still in its infancy, and is still prone to common household pitfalls that require occasional human observation.
Though not as thorough as washing the floors by hand, the Mint did leave the kitchen floors much nicer, and the proof was all there on the pad.
In the kitchen, partnered with the wet cleaning cloth and some Mrs. Meyers all purpose cleaner, the Mint was switched onto a Mop function and let loose. A half hour later, the floors not only looked cleaner, but the proof was right there on the cleaning cloth; the unit's 4lbs weight provides enough surface pressure to remove surface stains capably. Admittedly, the Mint is nowhere as thorough as hand cleaning the floor, but we could easily get used to relying upon a weekly schedule with the Mint doing kitchen duty, partnered with a monthly hands-on thorough cleaning for spic 'n span floors.
Improvements we'd love to see in version 2.0: daily and weekly scheduling via a wi-fi interface. Imagine being able to program a customized schedule, while also possibly offering feedback which rooms had the most debris cleaned, perhaps with a GPS-based visual mapping system to show the "where" and "how much was cleaned". Also a cradle charging system for the unit to automatically return to would make any future Mint model more hassle-free; it doesn't take that much effort to plug-in, but enough to warrant a note that you're responsible for keeping it properly juiced up for duty.
Overall, the Mint offers what we'd call a "charming" impression. It's not as tech-laden as the Roomba, but that's part of its appeal. Carpet and rug owners should stick to vacuuming, but if hard surface flooring is what you need, the Mint does it pretty well and at a reasonable price. And pet owners will likely find the unit coming back with a (disturbing) bonanza of their pet's shed coats.
Do we need a Mint? Hardly, as sweeping and vacuuming by hand isn't too difficult. But do we want one now? Certainly, as the white little robot quickly proved its capable ability to reduce cleaning duties over the span of the week, leaving us more time for work and play.
Pros: Yves Behar design, simple and friendly user interface, navigates furnishings well, able to perform several cleanings before recharge is needed, very capable dust and pet hair cleaning performance.
Cons: No scheduled/automatic cleaning or charging, can occasionally find itself stuck in a tight corner, not a replacement for vacuum.

Looks to be an interesting tool but seems to be slow. How big was the kitchen that took 30 mins to clean?
An all night charge gives how much cleaning time?
How much are the swiffer-like pads? I'm not sure it makes sense to spend that much on one of these when it's going to have an ongoing resupply cost, unlike the roombas.
Also, surprised the cat gets along with it!
SF Chris: we tested it for three sessions without needing to charge, but recharged it without letting it completely drain. T
yuppiescum: you can use any Swiffer or Swiffer-compatible inserts; the reusable inserts are currently included as a free 3-pack with every Mint (wondering if I should include the used ones when I return the unit).
I have a Roomba Dirt Dog and love it. It's just a sweeping unit, but it always performed beautifully sweeping up pet hair when I lived with cats. I feel like those sweeper things only work for dust/hair, and not for crumbs- if you had onionskin on the floor, for example, it would just push it around instead of sweep it up. I do like the mop pad function though, that's kinda neat!
I have a Japanese broom that spent years hanging on the wall when it wasn't getting me into clubs, but now that I have genuine imitation wood floors with a high rise sun that shows every. piece. of dirt, I am using it as a broom. It cleans like nothing else. It has a three foot wide sweep, and gets everything. I used to use it to get what the sweeper or the Swiffer missed, but I now I use it first, and use a dust buster to pick up the pile of dirt and dust. It's amazing. And it is soft soft soft so it doesn't scratch my incredibly delicate floors.
Picked up a Mint this weekend. For lack of a better name right now, I named it M-O after the little white cleaning robot in WALL-E). Hardest thing about it so far was waiting for its initial charge to complete (16 hours...). It's a lot of fun to watch. Was supposed to save me time cleaning, but I spent the time laughing as it bumped into furniture and figured out the small world of my apartment -- like a puppy, sort of.
I did a thorough mopping of my hardwood floors before running the Mint. I have a dog, so the little Mint had its work cut out. It did a fantastic job and I was impressed (disgusted?!) by the amount of debris and dog hair it picked up even after I had mopped.
Of course, cleaning does take a lot longer for the Mint than if I'd done it myself. It seems to do a nice job navigating tight spaces and around furniture legs. It only got stuck once, but that was kind of my fault as I wanted to see just how tight of a spot it could find its way out of. Oddly enough, I felt bad and caught myself apologizing to a little robot. It didn't seem to mind and just went on its way.
Unit did about 3 medium-sized rooms on a single charge. Clean up was a breeze -- just tossed the dirty cleaning wipe into the laundry and then plugged the Mint back into its charger.
I was happy to reclaim from chores a bit more time of my life to spend with what matters.
I got a Mint recently and have been using it twice a week. It's been really great because we have a small 1950s bungalow with hard wood floors (sorry all you apartment-dwellers).
To give one or two answers to some of the questions here in the comments, our Mint will sweep about 800 sq ft worth of rooms before needing a charge. It's nice in that it will finish the room when it needs a charge, but then it will refuse to do anything else until you charge it. Charging seems to take overnight, which I find frustratingly slow.
We use the washable sweeping pads and they work great! So I don't think people should worry about suddenly needing to buy swiffer pads.
I'm kind of an enthusiast and have posted a review here:

My Husband bought me a Mint while I was recovering from hip surgery. Kept the floors super clean and kept me entertained while on bed-rest!
