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:

    I received my iRobot® Roomba® 870 discount from iRobot for my honest review. The Roomba 870 is easy to set up and use right out of the box. It includes a DVD and guide book. I programmed mine to run every night just after bedtime. It's pretty quiet and efficient and doesn't bother anyone. It's great at picking up little crumbs and things kids leave behind, esp on the hardwood floors. I don't know how I ever lived without it!

      Comments about iRobot Roomba® 870:

      I have now been using the roomba 870 forabout a month and a half. My house is run by a few furbabies. We have a chihuChihuahua, a Pomeranian, a long haired cat, and a short haired cat. We also have a 9 year old son. To say our floors are the collection bin for crumbs, chunks of food, cat litter, and hair is an understatement. We have an old two story farmhouse. The upper floor has three bedrooms and a bathroom. The first floor is the kitchen with an eat in bar area,the dining room, the living room, a bathroom, and a bit of open space. We have a lot of hutches, antique cabinets, and randomness that I typically can not get around and under while cleaning without totally moving everything, which I rarely have time to do. The first couple nights we had the vacuum, I literally had to run it about 4 to 5 times per floor. The debris bin would be full and battery would be low, so roomba would have to dock. After emptying the tank and allowing it to charge, I would literally hit the clean button again and let it run. After this initial what I consider a break in period, I would run the roomba on each floor every other day. It cuts down on my manual cleaning.I literally havery not swept in weeks.

      It manages to travel under the beds, chairs, hutches, and cabinets. The only problems we have is the cats corner it when it gets under the dining room chairs. It can't go completely under the chair. It would have to go in, hit the support bar, and then back out. However our cats will literally let it go under the chair and corner it, until roomba tells us torelocate it to a new area.

      The bathroom rugs seem to also hang it up at times. However we have started picking them up first thing of a morning. So this isis a minor inconvenience we are willing to tolerate since we have seen a huge improvement in the cleanliness of the floors.

      The last problem we have is one of our beds has a cross member which the vacuum can wedge under, however for whatever reason it hits it just right to turn it off as well. This room we typically just have to watch roomba closely.

      Now we have seen a huge improvement in the cleanliness of our hardwood floors. There are less dust bunnies. I have moretime for other things as I am not spending nearly as much time cleaning. The cats have an expensive new toy that keeps them occupied for several hours.

      I absolutely love the roomba. I am so glad I was invited to participate in this campaign. A few suggestions that I have. Add in a find me button on the docking station. Press it and the roomba should start beeping. This would alert me to its location in the event it gets hung up on something. When it got stuck under the bed it took me a bit to find it. Recess the power button a bit farther or add a cover to prevent accidental pushing when it gets wedged under something or when the cat bounces on it. Prevent tank spillage when you go to remove the tank to empty it. Every now and then mind would spill contents when I went to pour them.

      Overall I loved the campaign and would have no qualms about purchasing one full price. I got this rroomba at a discount through a bzzcampaign

      Comments about iRobot Roomba® 870:

      I don't have a lot of experience with robots, but I can tell you that Alice, my new iRobot Roomba 870, is my favorite. I received an iRobot® Roomba® 800 series discount from iRobot®.

      Before Alice, I used a complicated system to sweep our hardwood floors. I pushed around a wide dry mop, then cleaned the mop off with a handheld vacuum. It involved a lot tedious work and awkward bending over. In the carpeted basement, I used a traditional vacuum - again, a lot of work.

      Alice makes the whole process so much easier. Now when I want to clean our hardwood or carpet floors, I just turn her on and get out of her way. Like magic, I return to find the entire floor clean. It's amazing! I wish I had gotten a Roomba sooner.

      We named our iRobot Roomba 870 Alice, after Alice the maid from The Brady Bunch. My 2-year-old daughter was a bit scared of Alice at first, but she has gotten used to her. Now she chases her around the room saying "where's Alice going?" The thing is, you can't tell where she is going to go next, but somehow, Alice gets the entire floor clean. It gets around all your furniture, but we move the smaller stuff out of the way if we can, for a more thorough job. The Roomba is only about 4 inches tall, so it also fits under the couch - somewhere I NEVER bother cleaning myself!

      The iRobot Roomba 870 comes with two virtual walls, which prevent the robot from going where you don't want her (or him) to go. Those worked very well for us, though the Roomba turned around a few inches sooner than I expected when using them.

      The "cliff-detection" system, which prevents the Roomba from falling down stairs, did not really work for us. Alice comes to top of our stairs, stops, and says "error, please reposition Roomba and start again." But that's ok, because I just use the virtual walls at the top of the stairs.

      The bin of the Roomba does get full more quickly than regular vacuums, but that doesn't bother me. Obviously, the entire thing is much smaller than a regular vacuum. I have Alice clean our entire carpeted basement, which is about 700 square feet, and I only have to empty the bin once in the middle.

      As I said, I wish I had gotten a Roomba a lot sooner - it has saved me lots of time and effort. I will not be vacuuming our floors anymore. I love Alice the Roomba, and I would recommend the iRobot Roomba 870 to anyone.

        This is a powerful machine, lots of suction and quiet operation. I can set it to run when I want and it gets in all the nooks and corners with ease. The Roomba transitions from carpet to hardwood with ease and it finds the dog hair before I do. I love it.

          I have been loving the iRobot® Roomba® 800 that I received at a discounted price from iRobot®. I have tile, hardwood and carpet floors and it works great on all. I also live in a trilevel with tons of stairs but it is able to vacuum right up to the stair edge without tipping over. I was super impressed the first time I used it because it can navigate around chair legs without having to move the chairs, vacuums under the clothes in the closet and around exercise equipment and other obstacles.

          Not that it would change my review, but I did get this at a discount from iRobot to review.

          Now that we don't have to do it, our floors get swept and our carpets get vacuumed multiple times a week, especially our living room since our kids drag in Sand and Dirt daily. It is pretty quiet and does an amazing job at getting up so much dirt in places that already "look" clean. It does a great job but if I had to complain about something I would have to say that it has some spots it really likes to hang out in and others it just breezes through once. Still does a better job than I could do. Beats the pants off of my Kirby.

          Comments about iRobot Roomba® 870:

          This little guy will save you time, especially in a high traffic or dusty household. I have two dogs and one is a major shedder. Instead of hauling my big vacuum out every day, I run the Roomba so that I only have to vacuum once a week and things stay as clean as before!

          I was hesitant to purchase one at first. I obtained a great discount to try the 870 and am so glad I took the plunge. The overall convenience and time-savings has been great.

          There are a few things I wish were better:
          1. the bin is VERY small so I am emptying it constantly
          2. the unit comes with two 'virtual wall' accessories. I find these very necessary and even find you will probably have to purchase a few more to maximize the convenience of owning one of these.
          3. pets definitely hate this one. You'll have to separate the two because they don't play well together -- even if it is funny to watch.

          Comments about iRobot Roomba® 870:

          My name is Tonya. I live in a 1300sf house that has hardwood floors with my husband and five(5)cats. Up to this point, I have dustmopped and swept theI have been so wanting one of these for years, but was afraid of disappointment at a high price tag; but after receiving my trial coupon from BzzAgent, I really had nothing to lose.

          I wasn't quite thrilled with Rosie right out of the box. I didn't bother with programming. I just pushed the button and she took off. About three minutes later, I saw the "empty bin" light come on. Then, again another three minutes later and so on. My first thought was that I was going to have to continuously be emptying that little bin and then she quit right under the bed. Well, that's what I get for not giving her a full charge before hiring.

          The next day after a full charge, I sat down to program her. It was a very simple setup where she would clean every day at the same time. Then at the appropriate time later on that day, I heard her start up and take off. Oh the excitement. She was hugging the walls and zigging and zagging and going under the couch and chairs. She was picking up so much hair that I had to keep emptying the bin, but she was getting it all; she even twirled around all of the furniture legs where dust and hair collected, where I used to have to move the furniture to get to it or if I couldn't move the furniture, it just stayed until it grew into dust bunnies and they would blow across the floor like little tumbleweeds when someone walked by. She headed into the kitchen and swept under the bottoms of the cabinets and appliances. She must have been hungry because she headed for the saucers I have in the corner with kibble and a bowl of water for the cats. Oh no! I remembered there were two virtual walls in the box and set the one there immediately and she left them alone after that.

          I sat down for a bit and didn't hear her after a while and found her pushing a couple of socks I was missing out from under the bed. I was surprised she didn't eat them, but she was making a strange noise and after empying the bin I found that she did eat some dead leaves that had fallen from my ficus, a receipt and a couple of candy wrappers that my husband missed throwing in the trash. After clearing her throat, I switched her back on and she continued working away until the time when she drove back to her dock to rest for the night.

          Overall, I love Rosie. There, I said it. She runs daily and now I only have to empty the bin after each session. It takes her about an hour to take care of our entire house and she docks herself for charging. She is not noisy or scary to my cats like the upright, although she is nimble and powerful. It didn't take her but a couple of days to learn the layout and for me to learn where to put the virtual walls for best results. I am very thankful for her and very pleased with her work and look forward to a long lasting relationship.

            Thank you for the iRobot® Roomba® 800 series discount from iRobot. This is what I think of this product after using it for over a month. I will never go back to vacuuming again. The iRobot gets under furniture over carpet and around objects that are in the way. It picks up pet hair, dirt, small bits of stuff and even pieces of dog food that are on the floor. I don't have to move the furniture to reach the back side with the vacuum. I tell everyone about it and when friends come by they want a demonstration of it in action. The only problems I have had is on our new rug there are sections that are black and the roommba will not go over them. When it comes to a black section it stops and turns and goes a different way or it says error and to move Roomba lol. I think the sensor think that the black sections are drop off and not solid and it is a little louder than I would like but overall this is a fantastic product. Thank you for allowing me a chance to try it.
