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:

After installing a doggy door for our two short-haired dogs, we were constantly stepping on dirt and debris that they tracked in. Not only does the Roomba keep the hardwood and carpet floors clear, but it also picks up a mass amount of dust and hair on a daily basis that we never even noticed before or saw the need the clean up as often. My couches are too low for it to fit under, but the fact that it gets under the bed is wonderful.

TIPS FOR USE - I would have it scheduled at least 5 days out of the week. The more it's running, the less it has to pick up and the less you'll have to empty its bin because it fills easily. Also, don't give up if your floors aren't clear after the first few days - it picks up so much that you need to give it time to get the floors in good shape. If you want a specific room cleaned efficiently, just shut the Roomba in the room or use a virtual wall to keep it in there. It will keep running until it deems the room clean, but if it has full range of the house, it will stop before the entire house is clean.

TIPS FOR PURCHASING - I'm actually a recent college grad currently drowning in student loans and following my military husband around the country. I know these things are expensive - but they are completely worth it. DEFINITELY spend the extra $$ to get a model with the rubber, as opposed to brush, rollers. Cleaning the Roomba each week is a simple but meticulous job, but the rubber rollers make it so much easier to take care of. I can't imagine cleaning out brushes every week, especially if you have long hair.

    This little Robot gets it all! I turn it on every morning before I leave the house. I have 2 small dogs inside & 1 large dog that's only inside at night, and this great little Robot gets all the dog hair, plus everything else. It goes around the furniture and reaches all the corners, it even gets under my chairs! I can't say one bad thing about it, it's one of the best things I've ever bought! I recommend it to everyone!!

    Comments about iRobot Roomba® 870:

    PROS
    Vacumed and mopped the floors before I used the Roomba 870 the first time. I am shocked about how much dirt and fuzz bunnies it picks up every day.

    Allegy systoms are already greatly reduced in only one week.

    Major time and back saver.

    Beaters and suction much better than I expected.

    Doesn't hang on fringe on Persan carpets and moves from hardwood to tile to different height rugs without problem.

    CONS
    Doesn't navigate between rooms in a larger (2,400 sq. ft.)home well. I have to break up the house into four sections using the virtual walls and manually move the Roomba between rooms.

    Drives me nuts to watch its random cleaning pattern. Solution: Don't watch just listen to make sure it is still working.

    SUMMARY
    I should have been cleaning the floors every day and just wouldn't do it. Roomba allows me to keep the house clean without devoting my life to it.

    FYI. If you don't have pets, don't waste the moneyon the 880. The 870 has the same "guts" and the "virtual walls" work just as well as the "lighthouses".

    Punchy does a fantastic job cleaning, but he does get stuck under the couch a lot. In addition I'm getting an error 5 which I've turned in a ticket to irobot. It's been a few days and I still haven't heard back. I'm sure it's a fluke, and I'd still buy another.

      This is my second. My Son has my first one after he rescued it and bought a new battery. It is probably 15 years old. They run it after the maid comes and it still fills up with dust. Seldom so I have to dust if I run it regularly on a schedule. Would never want to be without my Roomba.

      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.

          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.
