(Last updated: 12/27/11) Black Friday and Cyber Monday are past, but there are still deals this holiday season. I’ve decided to keep track of any deals that are available for robotic vacuums. This page will be updated as things happen. I’m on the lookout for any deals, so if you see any, let me know in the comments!

We’ve tested the Neato Robotics XV-11, iRobot Roomba 780, and the Evolution Mint and Mint Plus robots, and decided to put together something like a consumer reports style buying guide which compares and contrasts these products. All of these robotic floor cleaners are great labor-saving devices, but which device is going to be better for you depends on your preferences and situation.
Cleaning In our testing, all the robots did a good job of cleaning floors, so cleaning in and of itself isn’t a reason to choose one brand over another. One of the things to keep in mind is that these devices have cumulative effect. So the more you use them, the more clean your floors will be overall. Here are the strengths and weaknesses of each of these robots:
Pros: Powerful vacuuming, maps the room, avoids bumping furniture, can vacuum whole house in one go, can be scheduled, has auto charging dock. Mostly easy to maintain and in our limited testing requires less maintenance than the Roomba. Cons: No dirt-detect, no side brush, misses corners and areas right against furniture. Noisy. Will occasionally get lost or stuck. Can and will eat cords.
Pros: Thorough vacuuming from a product which has been around a long time and thus has been improved and upgraded over the years. Many models can be scheduled, will detect dirty areas, and have auto charging docks. Newer models like Roomba 780 detect when they’ve sucked up cords and will spit them out. Cons: Noisy, brushes and beaters require regular maintenance, robot runs into furniture,
Mint and Mint Plus
Pros: Silent, thorough, easy to use, maps the room as it goes, extremely easy to maintain. Can do double-duty, mopping as well as sweeping. Doesn’t require much room prep. Doesn’t eat cords. Takes up less storage space than the competition. Cons: Can’t be scheduled, doesn’t do carpets, won’t automatically dock to charger.
There really are some differences. Check out these two movies which compare how these three robots handle the same tasks, cleaning around a table leg and cleaning a corner.
Head to head
Neato XV-11 vs iRobot Roomba Executive Summary: We think that if the XV-11 had a side brush, and could stop eating cords, it would beat the Roomba, but for now, iRobot has the lead with the 700 Series robots.
By virtue of the fact that it runs into everything in the room, the Roomba is generally more noisy than the XV-11, which has a louder vacuum and beater. The Roomba strikes me as being more thorough, since it has a side brush, gets into corners better, and can fit under more furniture. The iRobot vacuum cleans sort of randomly, whereas the Neato maps out the room and cleans methodically, but our opinion is that, in the end, this doesn’t make that much of a difference to how clean the robot makes the room.
The XV-11 generally takes 30 minutes to clean our living room, and the Roomba takes about 50 minutes. The place where the XV-11 really outshines the Roomba is when it cleans multiple rooms. If you have thoroughly prepped all the rooms on one floor of your house, you can set the XV-11 running (or schedule it), and it will vacuum the entire floor with no human intervention and no need for arranging lighthouses. In our case, that’s a kitchen, bathroom, living room, office, and bedroom. Also, the XV-11 doesn’t bang into furniture and walls. Although it will gently bump things here and there, it is much more gentle with your furniture.
Neato XV-11 vs Evolution Mint Cleaner Executive Summary: If your house is mostly hardwood floors/linoleum or you’re only interested in cleaning your kitchen and bathroom, the Mint is the clear winner. If purchasing a robot to clean lots of carpeted areas, then the Neato wins.
As with all comparisons to vacuum cleaners, the first thing that must be mentioned is that the Mint doesn’t do carpets. So if your house is mostly carpeted, your choice to get an XV-11 instead is a no brainer. Our seriously unscientific timing indicated that the Mint is usually faster to clean a room for some reason. The Mint is almost silent. The Mint doesn’t suck up things like cords and cables, and so the Mint is less obnoxious and requires less room prep before running.
The Mint is shorter than the XV-11 and thus can fit under more furniture than an XV-11. So once again, in an uncarpeted room, the Mint is going to be a little more thorough because it can get in more spots and also because it does corners way better. Sadly, the Mint cannot be scheduled. Again, as with the comparison to the Roomba, the XV-11 outshines the Mint in multi-room cleaning, and is also (just a little tiny bit) more gentle on furniture and walls than the Mint.
Evolution Mint Cleaner vs iRobot Roomba Executive Summary: As with the above comparison, if your house isn’t mostly carpeted or you’re only interested in cleaning your kitchen and bathroom, the Mint is the clear winner. If you are interested in cleaning a carpeted house then the Roomba wins.
Yep, the Mint can’t do carpets. So that should be your number one factor in deciding between the two robots. The Mint cleans rooms much faster and is methodical where the Roomba is thorough with repetition. The Mint is quiet enough that you can have a phone conversation in the same room, whereas the Roomba you will want to run it when you’re not at home. The Mint doesn’t require as much room prep and almost no maintenance
Besides being the carpeting champ, the Roomba can be scheduled and also handles multi-room situations better than the Mint. The Roomba requires much more maintenance.
Mint vs iRobot Scooba Executive Summary: Problems with the Scooba line make it a robot we can’t recommend. For instance, see this Amazon page for user reviews of the iRobot Scooba 380. This is true of the older Scoobas, as well as the new Scooba 230, which we reviewed here. Please see our comparison article, here.
If you’re looking for a mopping robot, you should really spring the extra money for the Mint Plus (a.k.a. the Mint model 5200), which has a special mopping head. See our review of the 5200 Mint here.
And so there you have it. If you’ve got a house with a lot of carpeting, we recommend the Roomba 700 series robots over the Neato XV-11. There are cases where a person might want to go with the XV-11, which can clean a whole house floor in one go and is more gentle on the furniture. It’s also a little less expensive than most of the Roombas. For someone who is just buying a robot for kitchen and bathroom floors, the Mint is the obvious choice. With the Mint you get good performance and reliability at a much lower price. For a house that is mostly hardwood floors, the Mint might be the best choice there, too, depending on how many area rugs and how important some of the Roomba features (like scheduling) are to you.
Later note – Announced August 22, 2013, iRobot is now selling the Mint 5200 re-branded as the Braava 380t.
I bought the original Evolution Robotics Mint (model 4200) a year ago and I use it every week at home and love it. It’s really well designed and does a great job keeping our hardwood and tile floors clean. When I found out that Evolution Robotics was coming out with a new improved model, the Mint Plus (models 5200 and 5200C) I was really excited to see what they had done to improve this simple automatic sweeping and mopping robot. The good news is that they’ve really improved the robot, especially when it comes to mopping, and we whole-heartedly recommend spending the extra money to get the newer model.
Very briefly, the Mint robot is built to sweep and mop floors. It comes with wet microfiber cloths for mopping and dry microfiber cloths for sweeping. When it sweeps, it runs around the floor in straight lines. When it mops it uses a back and forth and side-to-side motion to wet and then pick up dirt as it goes.
Unlike Roombas, the Mint robots actually navigate around the room and keep track of where they’ve been. To navigate, they use a device called a NorthStar beacon which is a cube that you turn on and place on a table or counter in the room that the Mint is cleaning. The Mint cleans a room by going back and forth over the floor, and then running around the perimeter of the room. Like a Roomba, it has sensors to keep it from running off of cliffs and stairs.
The main advantages a Mint has over most robotic vacuums:
More gentle on furniture
Cleans same size room faster
Mops in addition to sweeping
Less prep work before cleaning
Some other robot vacuums have advantages over the Mint. For example, the Mint:
Can’t do carpeting (this is, admittedly, a big one)
Can’t be scheduled
Won’t return to charging dock when finished and charge itself automatically
For a more in-depth review of the original Mint, check here. For a side-by-side comparison of the Mint robot to an iRobot Roomba, read here.
The first thing I noticed when unboxing the Mint Plus, was that instead of using huge blocks of styrofoam to pack the robot, everything is in cardboard trays. I know not everybody cares about this, but for me it’s a big plus to have a company care about the environment and use “green” packing materials.
The Mint cradle model (the 5200c) comes with a cradle. Otherwise, the cradle is available for purchase separately.
In the box you get everything you need to get started. Everything is very clearly marked, and many of the items are packed with simple instructions in the packaging wrapped around the item (like the Pro-Clean Reservoir) or printed directly on them (like the NorthStar module). The NorthStar cube requires two C size batteries, and those are provided in the box, which is awesome.
What’s different in the Mint Plus
As you can see, the Mint Plus is black. Both robots are the same size and height. The Mint Plus comes with a cleaning pad that has a reservoir for dispensing liquid as it mops. The Mint Plus charges more quickly, getting a full charge in two hours. It also lasts 25% longer on a full charge than the original model. The NorthStar2 module is supposed to be more efficient and also has a better scheme for having the robot clean several rooms at one go. The Plus has a quick cleaning mode where it skips doing the perimeter. The Mint Plus also has a Pause and Resume feature where it can pick up from where it started if you need to interrupt it for some reason. The Mint Plus is made so that it can be kept in a charging cradle.
Looking at the Mint Plus, you can see that the front edge has more padding on it. There’s a rubber pad that runs all the way around the front. Like iRobot Roombas, the Mint robots will run into your furniture and walls. They try to slow down before they hit things, but people who use cleaning robots do tend to notice wear after using them for years. This padding is to help keep the robot from doing eventual damage to your things, and is much more substantial than the padding on the original Mint.
Under the hood, the Mint Plus has an upgraded battery. Both robots come with a 7.2 Volt NiMH (nickel-metal hydride) battery, but whereas the original Mint came with a 1500 mAh battery, the Mint Plus is packing a 2000 mAh battery. The measure “mAh” is short for milli-Amp hours and is a measure of how much energy a battery can supply over a period of time. Do the math how you will, but the manufacturer states that Mint Plus has 25% more battery time. The connectors for the different batteries are not compatible, so you won’t be able to buy a replacement battery for one model and use it in the other.
While the regular microfiber cleaning cloths are basically identical, the wet cleaning cloths for mopping are a little different. The cloths are a little smaller in the direction that gets tucked around the cleaning pad. This doesn’t reduce the cleaning surface at all, and was probably done to help keep the ends of the cloth from getting bunched into the middle and cause problems mounting the pad to the robot.
The charging brick is built so it won’t block other power outlets around it. This is awesome!
Evolution Robotics has made changes to the NorthStar Navigation Cube, which they are calling the NorthStar2. The original NorthStar cube was model 4261. Mint also sells a “second room” cube which is model 4262. The new Mint NorthStar module is model 4264 (which leaves me wondering what happened to 4263). The main change to the navigation system occurs when you get more than one cube and place them in different rooms. With the original system, the second cube would keep the robot out of the second room, and then when it was finished cleaning the first room, you had to pick the robot up and carry it into the second room. The new NorthStar system works such that the robot will clean the first room and then move into the second room by itself, afterwards. This makes better sense and doesn’t require human intervention to clean two rooms in one session.
Also related to the NorthStar, the Mint Plus is supposed to navigate more efficiently. I timed both robots cleaning a few rooms, and for a room that took around 15 minutes to clean, the Plus took about a minute off of the cleaning time when sweeping. Watching the robots when sweeping, I don’t notice any real difference. The promotional literature about the Plus claims that the NorthStar makes the robot clean larger areas more efficiently, so maybe I need larger test areas.
The Cradle is Nice
The Mint Plus is built with contacts on the back end to charge in a cradle. One nice thing about the cradle is that you don’t have to plug the robot in manually. With a cradle, there’s a space where the Mint “belongs” so it’s more likely to end up there. Also, it helps make the Mint fit into a way smaller space.
Mopping Has Improved!
If you’ve read my original Mint cleaner review, you’ll know that I wasn’t particularly impressed with the mopping job that that the robot did. To mop, you wet a mopping cloth, put it on the cleaning pad, and then run the robot. The problem is that the mopping cloth usually dries out before the robot can finish the room. So it never cleans up all the sticky spots or places where there is mud tracked into the room.
The engineers at Evolution must have known this was a problem because they’ve come up with a solution: The Pro-Clean Reservoir Pad. Basically, this is a pad that’s pretty much like the regular all-purpose pad that you attach the cleaning cloths to, except that it has a container for water (and mild soap if desired) and a wick that lets the liquid in the reservoir seep out into the cleaning pad. So the mopping cloth doesn’t dry out. As you can see from the picture, the reservoir is clear, so you can see what the water level is.
Since we got the Mint Plus, we’ve used the mopping feature twice. Once to clean the kitchen floor after it hadn’t been mopped in a long time, and the second time just before we had company. On the first run, there were several spots where something sticky had been dropped on the floor and dirt had accumulated on the spots. These were the kinds of areas where the original Mint might or might not do a good job on them. We were pleased and surprised when these spots disappeared from one cleaning with no pre-wetting of the spots. The second time, we needed to clean because it had rained all day, and we had carried groceries and other things in and out of the house enough times that there was some mud tracked into the kitchen. Again, the Mint Plus did a great job where the original Mint might not have got everything.
A Few Gripes
While it’s not as important with a Mint as it can be with its more noisy and obnoxious vacuum cleaning cousins, I really wish the Mint came with a scheduler. The rest of my complaints are really just minor quibbles. Here goes: While the cradle is nice, if it’s on the same floor as the robot is cleaning, the Mint will push it around the room. So you have to put the cradle somewhere else. Next, having two cleaning pads means that you need somewhere to store the one that currently isn’t on the robot (I told you these were quibbles!). Also, you have to remember to empty the Pro-Clean reservoir before putting it away because otherwise it will continue to leak water after you’ve put it away. Finally, the glossy black finish on the Plus collects and shows fingerprints, dirt, and dust.
A great little cleaning robot just got a lot better! While I would have really loved a scheduling feature on this robot, that’s my only really substantial complaint. The robot charges more quickly, can clean more area on one charge, has some other features like Pause/Resume that make it easier to use, and it does a much better job of mopping. Also, the robot can be used with a cradle, which is really nice. As of this writing, the original Mint is $200 US, and the Mint Plus is $300 without the cradle. The cradle is about $70.
If you’re wondering if a Mint robot is for you, consider whether or not a robot vacuum makes more sense. Our house is mostly hardwood floors with a tile floor in the kitchen and linoleum/marmoleum in the bathroom. For us, the Mint replaced our Roomba, and we love it. Someone with wall to wall carpeting throughout their house should consider how much they hate sweeping and mopping their kitchen and bathroom floors.
So, is the Plus worth the heftier price tag? I would say that if you already have a Mint and it’s working great for you, the new model is worth it if you really want or need one or more of the substantial improvements, like the fast charging, the improved mopping, and/or the cradle.
The same answer goes for someone trying to decide between getting the original 4200 or the Plus 5200. If you tend to get the deluxe model when you’re buying an appliance, it’s a no-brainer to get the Plus. Otherwise, you have to decide if the improvements are worth the extra cost. I didn’t expect to like the mopping feature as much as I did. I ran it just before some friends were coming over for dinner. I was preparing food while the robot was mopping the kitchen, and it “just worked”. To me, the satisfaction was worth it.
