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™ Extended Life Battery: iRobot® XLife™ Extended Life 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:

    When we unpacked the machine and used it the first time, I was disappointed how frequently it needed to be emptied and cleaned. I have since discovered that after the initial cleaning and the rooms got "broken in," that it does a much quicker and efficient job. Cleaning the bin was not as simple as knocking it against the trash bin. I had to shake and bang and stick my fingers in the opening to get all the dust out. Mind you we have pets and had never vacuumed under the beds, so of course it filled up so quickly, but not anymore! Now it is nice to be able to turn it on and let it do its thing.

    Comments about iRobot Roomba® 870:

    We have two dogs and have always struggled to keep our home free of dog hair accumulations which appear daily. The Roomba is the perfect solution, it picks up the dog hair from our main floor each night and has thus relieved us from daily manual vacuuming. Our home is much cleaner and we love it!

      Comments about iRobot Roomba® 870:

      We have an Alaskan malamute in a home with hardwood floors. This is a recipe for furballs big enough to swallow children. Instead of spending all evening vacuuming, we got a Roomba. We had been using a 500 series, which was excellent. I saw that the 870 has a different vacuum system designed to prevent fur tangling, which was a major issue with the 500 series brushes. After several weeks of daily operation, I am comfortable saying that the 870 lives up to my expectations and fur tangling has not been a problem. I was a bit disappointed to see the same old front wheel caster that I have to replace a lot due to the fur clogging the shaft. Overall, this is a great product that is worth the cost.

      Comments about iRobot Roomba® 870:

      The Roomba 870 is an excellent robot vacuum and generally performs very well. I bought it mainly for the main floor of my home and I am satisfied with the results. Main floor is all hardwood and ceramic tile. I'm always amazed at the amount of dirt this little robot picks-up. I sometimes wonder what pattern it follows but at the end, coverage is excellent as it manages to pass everywhere several times.

      My Roomba has some difficulty with my dog's hair on carpets (2nd floor of the house). It will pick them up but if I wait too long between cleanings, the Romba clumps the hair together and leaves it behind. Too much pet hair I guess and it sticks like velcro to the carpet. That's about the only downside I can see so far, which I can manage with more frequent cleanings.

      Maintenance on this model is a breeze. It takes about 5 minutes to remove the main parts and vacuum out the build up debris, then wipe it down with a clean cloth.

      I would definitely recomment this robot to a friend, especially if the price comes down a bit.

        Comments about iRobot Roomba® 870:

        I got this for a Christmas gift and I am so thankful that I did! I had discussed the Roomba products with a friend who has a one as well, so I knew what to expect before ever turning it on.
        I was amazed after the first time I used it. I had recently cleaned the house and I just couldn't get over how much dust, dirt, and hair it picked up. One of my favorite things is that it gets under furniture. I have hard surface floors in most of my house and with normal living plus pets, hair and dirt goes everywhere. it's so nice to look under a bed or dresser and not see dust bunnies everywhere!
        The thing about this machine is that it is a machine. My point is, it may leave a little dirt behind sometimes, it may not clean like I would, but I knew this going in. Running the roomba regularly helps a ton with everyday dirt and hair, but you still have to clean your house! It just almost seems like people think it's a huge miracle (which I think it is!), but I still clean my house once a week including sweeping and mopping.
        I am very impressed with this robot and am so glad I have one now! I have told anyone and everyone that'll listen that they should get one, too! I am very impressed and highly recommend.

        Comments about iRobot Roomba® 870:

        Fell in love with my Roomba 870 for a couple weeks. Then I noticed that it was leaving small 'strings' of rolled up dog hair. Contacted customer service who were so nice to send a new head. It didn't solve the problem. Another call to customer service, they send a replacement Roomba. Still same problem. Note that I have a long-haired Golden Retriever that is inside only in the evenings. I didn't want to return it because it is so convenient especially when I have to vacuum every day due to dog. I was willing to try anything to keep it. Problem was referred to tech people and they determined that it was not for my household. In summary, if you don't have a long-haired dog that constantly sheds, then I would highly recommend the Roomba 870.

              - even my husband does not mind "vacuuming" now. He has heart issues and could not vacuum before. I have a bad back and it gets under beds and couches so much better than I ever could. I had a 550 Roomba for some time and just "upgraded" to the 870 - it is wonderful.

                Comments about iRobot Roomba® 870:

                The last Roomba Scheduler 300 series I owned since 2007 gave up summer 2014. The Roomba 870 that I now use to clean my living room carpet of dog hair is far more powerful and efficient at picking up the hair and dust. I can vacuum with my heavy duty vacuum one day and the next day the Roomba will still pick up dirt that the upright missed.
                What I learned from my first Roomba is that they need constant maintenance to function properly. Besides emptying the bin, it is necessary to follow all the steps for maintenance often. Do that and you will enjoy your "helper" for many years.
