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.

        The Roomba 870 does a pretty good job picking up most things that find their way on the floor. Surprisingly it even picked up a bottle cap that made its way under a counter. I used the Roomba on hardwood floors and area rugs. On the hardwood floors, I found there were some fine dust foot prints and things that the Roomba would not pickup. It also seemed to get bogged down in our shag area rug. It made it through it but you could hear the motors struggle which will wear down the batteries fast.

        It handled everything else on my floor except for some very fine dust that I had to sweep up myself.

        I received a coupon to purchase this machine as part of a review program.

          Comments about iRobot Roomba® 870:

          We have had our Roomba for a month now and initially gave rave reviews. It cleans extremely well and is convenient and easy to use. However, after only one month, the battery life has deteriorated so significantly that it cannot even finish cleaning a small, barely dirty room. Battery life now is less than one hour!!
          Today it shut down after 45 minutes! In a three or four bedroom house, it would be a major pain to use the Roomba for decent cleaning if it needs to charge for hours and hours after just doing one small room!

          We regularly check and clean the brushes, wipe down the Roomba regularly, empty the dirt compartment, we clean out the filter - all on the recommended schedule or even more frequently - and yet it cannot ever clean for longer than an hour anymore without needing a full charge.

          What a huge disappointment!

            I have two cats and two boys so I normally sweep and vacuum every day to keep my house (especially my kitchen) the way I like it. Because I have chronic pain I would dread having to pull out the vacuum. This sweet little Roomba has been such a godsend. It is easy to set up, program and use. I can go relax while the Roomba cleans up all of the dirt, dust, and cat hair. It even gets the corners clean! When it is done, the collection bin is easy to empty, and I am always thrilled to see how much it sucked up off of my floors.

            I made the purchase because I was able to take advantage of a discounted price from iRobot. I am beyond thrilled that I did, and now I want one for my upstairs, too!

            I am so happy with my purchase of the Roomba 870. I received my iRobot® Roomba® 800 series discount from iRobot® and was thrilled to be able to try the Roomba with this promotion. We use our Roomba almost daily, moving it from the first to second floor and back every day. We are planning to get another base we can keep upstairs so we can make this easier for us. There really aren't too many negatives I could find with the Roomba 870 we purchased. It did get stuck under our coffee table so we place a rolled up blanket there to avoid that. Other than that we adore having our new robot and think it's worth every penny. It's such a time saver for us having two kids and a dog. We lead a busy lifestyle and vacuuming was always squeezed in after bedtime for the kids usually. Now we can run the Roomba while we are away at work and school. I wish we had purchased one sooner!

              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.

              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.
