iRobot Roomba® 870 Full Specifications

The AeroForce Performance Cleaning System
Ideal for homes with pets and allergy sufferers, Roomba 870 traps dirt, particulates and allergens, drawing them into the sealed, HEPA-filtered bin. Here's how AeroForce works:

  • Tangle-Free AeroForce Extractors: Dual extractors grab and break down dirt and debris from any floor type. No brushes mean no tangles for you.
  • Airflow Accelerator: The accelerator creates a sealed channel that concentrates the airflow, drawing in more debris.
  • High-Efficiency Vacuum: A compact and efficient high-powered motor provides a 5X improvement in air power than previous Roomba generations.

Effortless Cleaning
Dirt happens every day. Keeping up with it just got easier.
  • Docks And Recharges: Roomba returns to its Home Base® to dock and recharge.
  • Cleans On Schedule: Roomba can be preset to vacuum up to seven times per week.
  • iRobot XLife™ Battery: iRobot XLife Battery delivers twice as many cleaning cycles as previous Roomba batteries, doubling the time before you may need to replace your Roomba battery.
  • Avoids Off-Limit Areas: A Virtual Wall® keeps Roomba in the rooms you want to vacuum and out of the ones you don't.
  • Lets You Know When Bin Is Full: Indicator lets you know when bin needs to be emptied.

iAdapt® Responsive Navigation Technology
In coverage tests, Roomba out-cleans the competition thanks to iAdapt Technology, iRobot's advanced system of software and sensors. iAdapt enables Roomba to find its way around any shape or size of home, covering every area of floor multiple times.
  • Finds Dirt And Debris: With Dirt Detect Series 2, Roomba uses optical and acoustic sensors to find dirt and perform concentrated cleaning.
  • Cleans Like You Would: The Persistent Pass Cleaning Method employs a back-and-forth cleaning pattern to apply elbow grease in areas where it senses excessive dirt.
  • Vacuums Along Wall Edges: Roomba uses Wall-Following Technology to clean right up to wall edges and kickboards.
  • Won't Get Tangled Up: Anti-Tangle Technology keeps Roomba from getting stuck on cords, carpet fringe and tassels.
  • Won't Fall Down Stairs: Cliff-detection sensors allow Roomba to avoid stairs and other drop-offs.
  • Won't Damage Furniture: The molded, soft-touch bumper cushions the contact between Roomba and furniture, walls and other objects.
  • Pushes Past Soft Obstacles: Light-Touch Bumper Technology accurately discerns soft barriers from solid barriers, allowing Roomba to go under curtains, bed skirts and couch skirts.

      Comments about iRobot Roomba® 870:

      I purchased the iRobot Roomba with a discount by iRobot and I'm happy I did.

      I was skeptical that the iRobot Roomba was going to be able to keep my floors clean. With 2 dogs, a cat and a busy family in and out of the house all day, I wondered how good will this product clean?

      The product was easy to set-up and was up and running in no time. It's looks well built and bigger and thinner than expected.

      Vacuuming is a chore nobody in my house likes to do and with two clicks of the "clean" button the iRobot, that chore is now much easier. It cleans in an unorganized fashion, all over the room, but it was able to cover the entire carpeted living room in about a half hour. The vacuum suction was strong, picking up pet hair, dust and fibers without losing power. It circles furniture legs, and moves under furniture easily and makes flawless passes between carpet and bare floors. The red indicator lights up when it's full and it's easy to empty. I had to empty this three times through the clean session of the whole house.

      The iRobot is a lot quieter than expected. Most of the time I didn't pay attention to it at all. It self docks and recharges itself.

      A couple of times the iRobot got itself trapped in wires running behind furniture and once it got itself trapped in a corner and couldn't find an exit, but overall, this is an amazing machine.


      To vacuum other rooms, like bedrooms, you do have to physically pick it up and place it in there. After about an hour, I empty it and bring it to the next room. At the end of the week, I have to clean the front wheel and spinning side brush from hair and long fibers.

      Overall, the iRobot Roomba has made an incredible difference on my floors. They always look clean and dust free. About once a week I have to do a manual cleaning on the floors, but that goes much more quickly than what it use to. It's great product and I would recommend this to anyone.

      Comments about iRobot Roomba® 870:

      Our Roomba is very helpful cleaning up after us and our 2 dogs. We've been finding less time to cleanup with our toddler and another on the way. It's a pretty versitale machine and I'm impressed how well it crosses between hardwood, tile, area rugs and even other surfaces!

      We have to empty the bin every day, but that's to be expected with the amount of messes we make. We have run into problems where the Roomba has trouble going over our rug with a dark pattern. It goes sometimes and other times it gets stuck because the cliff sensor think the black is a gap and stops the Roomba from "falling". Since out first floor doesn't have any "cliffs" on our first floor, we just taped over the sensors and it seems to be working.

      Comments about iRobot Roomba® 870:

      I received a discount from iRobot to purchase the iRobot Roomba 870 and review it. On the whole I think it's a good machine. My husband has been wanting to get one for awhile now, so he was all for trying it out. My cats were actually not as spooked by it as I thought they would be, so I don't have to worry about how they will react while it's running. I like the convenience of letting it run while I'm busy doing something else, although I wish there was an auditory alert when the bin is full or that it would pause itself. As it is, I do have to check on it occasionally to see if the light is on saying the bin needs to be emptied. It picks up cat fur pretty well, which is something I was worried it wouldn't be able to do. I'll continue to use it to help maintain the floors and keep up with all the cat fur, but I don't yet think it will replace my Dyson vacuum.

        Comments about iRobot Roomba® 870:

        So our Roomba 870 (Whom we named Chase) is awesome! There are not many other words that can encapsulate our Roomba Mr. Chase.
        Chase cleans all floors, including all thicknesses of carpets, wood floors, linoleum tile, ceramic tile. Pretty much everything.
        He is methodical and efficient. It is a great motivator for our kids to clean up before Chase comes in to consume all things on the floor. He works great.

        Some bullet points to highlight some pros and cons:

        Pro:
        * Automated cleaning machine. He cleans unattended any floor.
        *He will avoid cliffs and is capable of negotiating obstacles including cords and furniture.
        *easy to service, easy to clean. Seriously his rollers come out with two clips. The filter is one clip.

        Cons:
        While there are not many and the ones that exist are minor. I still give this device a 5/5 stars
        * The invisible walls that contain the Roomba have a conical beam like "<" which makes blocking some types of entrances awkward if you still want the Roomba to get close
        * His bin is pretty small, though after 'seasoning' the surfaces, he typically will not fill up before completing the floor
        *He can get lost in larger rooms and the Lighthouse component is not compatible with this Roomba (bummer).
        *He once and awhile will get stuck in our sliding door track depending on his angle of approach.

        Overall Roomba 870 is a great investment. I was able to pick this guy up with a generous discount from iRobot which made it even more worth the investment.

        10/10

        Comments about iRobot Roomba® 870:

        I was a little hesitant to make such a large purchase on a vacuum, but since I received this at a promotional cost, compliments of iRobot, I decided to make the purchase. I must say the Roomba cleans very well and takes the thought and effort out of cleaning. I will note though, that it is a very good idea to walk through your house, before the Roomba cleans, in order to move objects out of its way or off the floor, i.e. shoes, pet toys, cords to lamps, etc. Especially helpful since I did not vacuum every week, and it sure is wonderful to have crumb & debris free tile floor throughout my house. I have many things to review: (1) Because I have such an open floor plan with my living room, kitchen and dining room, the two lanterns/lighthouses come in superbly handy to contain the Roomba to a smaller area and once it's finished, I move it to the next area. I usually divide my large open space in half with the lanterns. Once it finishes the entire house, it returns to the docking station on its own. (2) the Roomba maneuvers very well around furniture and up onto our heavy pile area rugs. I have yet to see it get stuck where I had to manually move the Roomba. This is a necessity if you're going to auto schedule your cleaning during hours that you are not home. I have noticed the Roomba has a few scratches on top after 5 or 6 uses from rubbing under furniture, but the furniture is not damaged. (3) At first, our cat didn't know what to make of this thing. He would stare it down like it was an alien. After a few uses, he could care less. He's even been sitting in the living room looking out the sliding glass door and the Roomba came up and bumped him in the butt, he turned around with a careless look on his face and went about his usual business. However, the Roomba does move his food & water bowl, but that's a small price to pay for what this vacuum does. Also, my cat has a few toys that contain strings and the Roomba catches these items in the rollers and jams, so it's important to move all these items from the floor. (4) I have shoulder length hair and find that the Roomba often needs its roller brushes cleaned out to remove hair. This is probably my only gripe about this product, hence the 4 stars, since I set the auto cleaning feature and on more than once occasion I have found the Roomba stopped in a room with the error light blinking because the rollers needed cleaning to remove debris (aka hair). (5) I am amazed at the amount of cat hair this things picks up throughout the house. I was shocked & disgusted at the thought that I was living in such filth on my tile and area rugs. (6) I have read about people complaining that the Roomba is very noisy. I don't think it's anywhere nearly as loud as a regular vacuum, especially when its running on carpet. Overall, I am very happy with this purchase. While I would not say this is the end all be all of vacuuming, I think it definitely helps keep my house clean and dramatically reduces the need for me to to manually run a vacuum. Less time cleaning = more time having fun...and that I love!

        Comments about iRobot Roomba® 870:

        When I received my Roomba 870 I got it all set up and set it on the charger. I have had a Roomba before, it was a discovery model and it was noisy, battery needed a longer life. So last year I finally cut ties and recycled her. Then I got this great chance to get one from Roomba at a steep discount to try their product. I have to say I am back on the Roomba bandwagon. This new 870 makes about half the noise and picks up twice the dirt for twice as long. It actually gets my living room, dining room and hallway done before it goes back to home base. I also like the newly designed and much larger waste bin. It seemed like I had to empty the old one out before she was done in one room. This 870 does 2 rooms and a hall without filling all the way up. Overall great product. Thankful for the discount.

          I love Herbie! Ever since I used it for the first time, I am so happy I spent the money. My carpet has never looked better, and all I have to do is dump the bin when it's full and clean the filter once in a while. I was doubtful because I have two small indoor dogs, but it picks up their hair like it's nothing. I'm thrilled with it and highly recommend.

            Comments about iRobot Roomba® 870:

            I received my Roomba 870 series for an honest consumer review with a discount provided by iRobot. I have now had the roomba for exactly 4 weeks tomorrow and it arrived the day after I had surgery. My restrictions were no vacuuming so I became enamored with my Roomba right away. I have spent the last month paying close attention to the detailed selling points iRobot uses on their video on this website. Cliff Detect, Clutter Navigation, Anti-tangle, Light Touch, Soft Touch, Persistent Pass, Wall Follow, and Escape Behavior. I have done "set-ups" to test these features and each time Roomba has passed my expectations. The only thing I can say is you must empty after each use especially if you have a schedule on it. I think the buttons and sub prompts for menus are easily understood. I have to empty 2x if I allow Roomba to do entire home of 2100 sq ft. Also keeping hepa filter clean for use is important. I would recommend purchasing extra hepas and whiskers.
