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 love my iRobot Roomba 870. It works great on my hardwood floors, tile and carpet. The transition between surfaces is flawless.
    I especially love that it gets under my beds and furniture. No more trying to get all the dust bunnies for me! My robot does it!
    It is a bit expensive. (I did get a iRobot Roomba 800 series discount from iRobot, so that helped a lot.) However, if you compare it to the cost of a Dyson, it is comperable and, unlike Dyson, it does the work for you :)

      Comments about iRobot Roomba® 870:

      I was able to purchase this as part of a product review for BzzAgent. This product saves me so much time during the week. It is perfect for picking up the pet hair from our two dogs during the week. Because it can't do stairs and isn't great about getting in corners, behind does or furnitue I still vacuum with an upright on the weekend. I have noticed that since the floors are being swept daily or rugs are looking nicer between washing and there is less dog hair in our house in general. I love that it does it's thing and then docks itself without having to follow it around or use a remote. The virtual walls are a lifesaver too. We have stairs and dog bowls we need the Roomba to avoid. Everything else needs to be picked up. The Roomba doesn't get caught on or tangled up in much but of course it won't clean a spot if something else is already there. Its pretty good about sensoring walls and furniture but does bump in to a few things.

        I received an iRobot Roomba 800 series discount from iRobot. My brother's family has a very much older model and so after seeing it, I was pretty much on the fence about getting on. Lo and behold, a discount appears at my door to get the iRobot Roomba 800!

        I love how "independent" the Roomba 800 is! I just press the button to turn it on and off it goes! My house gets dusty and you can tell easily because I have hardwood flooring. The Roomba 800 does a great job to get those nooks and crannies and areas that I'm too lazy to bend down and clean by hand! The Roomba 800 keeps my hands clean and makes maintaining the cleanliness of the house easy!

        Whenever my little nephew (1 1/2 years old) comes by, he likes to press the button and claps for joy whenever little Recon (nickname for my Roomba) shoots off and searches and destroys the dust bunnies!

          I use the iRobot Roomba® 870 for my apartment and it sucks up every little dirt and garbadge. It knows when ti will hit a wall and will stop and spin around and proceed with the cleaning. Once done it goes right back to the docking station to charge. I have no complaints as of today

            Comments about iRobot Roomba® 870:

            I purchased my iRobot® Roomba® 800 series with a discount from iRobot®, and I was so excited to try their new model! This is my third Roomba and there are some great improvements that this one has over past models.

            First of all, I LOVE the new brushes, they're textured rubber instead of the bristle brushes and they're way easier to clean!

            Next, this model runs way quieter than previous models, I can actually have a conversation with it running in the room. Previous models I would turn on when I left the house because they were just so noisy while running.

            This model is also more efficient so it gets done faster and doesn't run out of battery half way through.

            It's even better about not banging into things than my previous model. I had a really early model that just about drove me crazy banging into walls and such, my second model was way better and didn't really bang into walls but it had a habit of banging into less stationary objects like chairs and such. This new model usually slows down and just taps the object instead of banging into it.

            I love my new Roomba!

              Comments about iRobot Roomba® 870:

              As a pet owner I am always looking for an easier and effective way to stay on top of cleaning dog hair from my carpet. That is why I was very excited to order a Roomba 870 when I received a discount from iRobot so I could review it.

              I thought it was extremely quick & easy to unbox Roomba and get it scheduled for daily cleaning. It only took a few minutes! I used one of the virtual walls to keep Roomba from getting stuck under my low sofa.

              The first few times I ran Roomba I was amazed how fast it filled up - I had been missing alot of dust and hair with my previous vacuum. Really helps me stay on top of cleaning up after my pet. My dog isn't best friends or ridding Roomba around like you see in some videos - but he isn't scared either.

              I was amazed the first time I saw Roomba 870 fit right under my bed and then return with all the dust. That was a place I never took the time to clean before getting a Roomba.

              Before I got my Roomba 870 I was worried it would go right over the edge of the stairs like a lemming. Fortunately it is smarter then that! My Roomba 870 turns away as soon as it gets close the staircase. This is however also a drawback as a standard vacuum is still needed to clean stairs.

              I love my Roomba 870 and have even personalized it with bunny ears so Room-Bun looks cute while cleaning up all the dust bunnies around my house!

                I love my Roomba. This model is much quieter than my previous 500 series. The brush was a bit tougher to clean, but it seems that it pulled more dirt from my rug. I didn't notice this, but someone had asked about the buttons and I had to push for them to lit up to know what it was for.

                  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.

                    We are a busy household with 4 cats - we rarely have time to drag out our heavy vacuum and do our floors. I love that I can schedule this unit super easy, and it goes to work, and transitions easily between carpet and hard wood! We have been very impressed with how much stuff it has extracted. It is fairly quiet (compared to our Dyson). So far we are in love. Best investment ever. I received my iRobot® Roomba® 800 series discount from iRobot®, and now my husband wants one that just does our upstairs too! Wish we had another discount! lol
