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:

iRobot products are wonderful. Roomba 870 works just as described. I have had Roomba 530 since 1999 and it is still going strong. I needed another one for the upstairs so I did not have to be carrying it back and forth which is why I bought the 870. I have recently acquired a cat which sheds constantly and the 870 does an outstanding job of picking up the hairs. The programming works well.

My only complaint is that is doesn't do the stairs!!

    Comments about iRobot Roomba® 870:

    I started with my first Roomba 42xx Scheduler series vacuum in 2008. I bought it refurbished and we had hardwood floors. After 2 years of continual use and loving the idea of not having to vacuum manually again we moved into a new home that hard plush carpeting. The older 42xx vacuum didn't fare too well on carpet, so it went into hibernation. In 2014 we moved again and back with hardwood floors. I pulled out the Roomba and bought a new battery, worked like a champ. However, the older style brushes with bristles would often clog with our Golden Retrievers long and often shed fur. That's when I decided to go with the new Roomba 870. Completely autonomous scheduled for cleaning 3 times a week our entire first floor (hardwood floors and 2 large wool rugs), I couldn't be happier. I only have to empty the bin 3 times a week and clean the filter once a month. Excellent cleaning and suction on the new Roomba, no bristles on the rollers to get clogged, and reasonably quiet, I am very happy. I show our friends and family and I wonder why anyone would ever spend any time vacuuming now.

      Comments about iRobot Roomba® 870:

      Initially skeptical about the new rollers replacing the brushes. Quickly began to appreciate the cleaning power of the stronger air flow and no more cleaning of the brushes. The ends of the rollers still need cleaning but easier. Impressed that less carpet fibers are found in the dust bin and that the dust seems finer (size), helping with allergies. Maybe even less buildup on the HVAC filters? Noticed better cleaning of high traffic carpet vs the 700 series we've used for years.

      Comments about iRobot Roomba® 870:

      I paid full price for mine. I dont feel bad about that as I feel he is worth every cent. I AM sad I did not get the 880 because (as I have learned here) I cannot get a lighthouse for him. :(

      but hey in a few years....

      I have even contemplated giving my 870 to my son and getting an 880 for us. He does not know it yet but he would love it!

      have not programmed him to run on his own yet. still to new and having much fun with him.

      I DO tell everyone who will listen, you gotta get one of these things! told my doctor the other day in fact. Antonio is a marvel of modern engineering and is such a class act.

      if he were half an inch shorter he could get under my couches and coffee table. as it stands now he gets wedged under the coffee table from time to time. Will figure something out for that eventually I am sure.

      If you dont have one, GET ONE! Great gift idea also. It is a gift that will be used every day and enjoyed for a long time to come.

      The component construction means I will have this guy around for a long time. I can replace any small part that gives out. I just cannot say enough about this guy!

      O.K. I will shut up now and let you get to the other reviews. I read them all (282) and only 2 people said they would not recommend this machine to a friend. I suspect they had a defective unit.

        Run this little guy ragged! He is constantly on the go. Have to empty his butt often because of pet hair. Also have to clean his parts regularly for the same reason, but he is an amazing little guy! Got him for the wife for X-mas and we love him! I am amazed at what he picks up! This is truly the little robot that could! If you don't have one GET ONE!

        Comments about iRobot Roomba® 870:

        I was really impressed with the amount of dirt and duct this picks up. I have a Puggle dog that sheds a lot an the Roomba 870 is perfect for her. I can't believe how much this picks up, I thought it was manufacturing dirt and duct in the bin each time I emptied the bin. I like the way the Roomba vacuums under the bed and furniture, and that it will go back to the base and charge itself. I had the schedule set at 4 times a week and it worked perfectly, then unexpectedly it started not to pick up any more. I called Roomba Tech Support and the had me run a couple diagnostics to pick up dirt. They initially sent me a dirt bin replacement, but that didn't help. They after 3 calls to tech support they replaced the unit.
        PROS: Picks up great, quiet operation, vacuums under bed & furniture easily
        CONS: Small dust bin, expensive, breaks down sooner than expected.

            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.

            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!
