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 received a discount from iRobot to purchase the iRobot Roomba 870 and review it. On the whole I think it's a good machine. My husband has been wanting to get one for awhile now, so he was all for trying it out. My cats were actually not as spooked by it as I thought they would be, so I don't have to worry about how they will react while it's running. I like the convenience of letting it run while I'm busy doing something else, although I wish there was an auditory alert when the bin is full or that it would pause itself. As it is, I do have to check on it occasionally to see if the light is on saying the bin needs to be emptied. It picks up cat fur pretty well, which is something I was worried it wouldn't be able to do. I'll continue to use it to help maintain the floors and keep up with all the cat fur, but I don't yet think it will replace my Dyson vacuum.

    Comments about iRobot Roomba® 870:

    So our Roomba 870 (Whom we named Chase) is awesome! There are not many other words that can encapsulate our Roomba Mr. Chase.
    Chase cleans all floors, including all thicknesses of carpets, wood floors, linoleum tile, ceramic tile. Pretty much everything.
    He is methodical and efficient. It is a great motivator for our kids to clean up before Chase comes in to consume all things on the floor. He works great.

    Some bullet points to highlight some pros and cons:

    Pro:
    * Automated cleaning machine. He cleans unattended any floor.
    *He will avoid cliffs and is capable of negotiating obstacles including cords and furniture.
    *easy to service, easy to clean. Seriously his rollers come out with two clips. The filter is one clip.

    Cons:
    While there are not many and the ones that exist are minor. I still give this device a 5/5 stars
    * The invisible walls that contain the Roomba have a conical beam like "<" which makes blocking some types of entrances awkward if you still want the Roomba to get close
    * His bin is pretty small, though after 'seasoning' the surfaces, he typically will not fill up before completing the floor
    *He can get lost in larger rooms and the Lighthouse component is not compatible with this Roomba (bummer).
    *He once and awhile will get stuck in our sliding door track depending on his angle of approach.

    Overall Roomba 870 is a great investment. I was able to pick this guy up with a generous discount from iRobot which made it even more worth the investment.

    Comments about iRobot Roomba® 870:

    I was a little hesitant to make such a large purchase on a vacuum, but since I received this at a promotional cost, compliments of iRobot, I decided to make the purchase. I must say the Roomba cleans very well and takes the thought and effort out of cleaning. I will note though, that it is a very good idea to walk through your house, before the Roomba cleans, in order to move objects out of its way or off the floor, i.e. shoes, pet toys, cords to lamps, etc. Especially helpful since I did not vacuum every week, and it sure is wonderful to have crumb & debris free tile floor throughout my house. I have many things to review: (1) Because I have such an open floor plan with my living room, kitchen and dining room, the two lanterns/lighthouses come in superbly handy to contain the Roomba to a smaller area and once it's finished, I move it to the next area. I usually divide my large open space in half with the lanterns. Once it finishes the entire house, it returns to the docking station on its own. (2) the Roomba maneuvers very well around furniture and up onto our heavy pile area rugs. I have yet to see it get stuck where I had to manually move the Roomba. This is a necessity if you're going to auto schedule your cleaning during hours that you are not home. I have noticed the Roomba has a few scratches on top after 5 or 6 uses from rubbing under furniture, but the furniture is not damaged. (3) At first, our cat didn't know what to make of this thing. He would stare it down like it was an alien. After a few uses, he could care less. He's even been sitting in the living room looking out the sliding glass door and the Roomba came up and bumped him in the butt, he turned around with a careless look on his face and went about his usual business. However, the Roomba does move his food & water bowl, but that's a small price to pay for what this vacuum does. Also, my cat has a few toys that contain strings and the Roomba catches these items in the rollers and jams, so it's important to move all these items from the floor. (4) I have shoulder length hair and find that the Roomba often needs its roller brushes cleaned out to remove hair. This is probably my only gripe about this product, hence the 4 stars, since I set the auto cleaning feature and on more than once occasion I have found the Roomba stopped in a room with the error light blinking because the rollers needed cleaning to remove debris (aka hair). (5) I am amazed at the amount of cat hair this things picks up throughout the house. I was shocked & disgusted at the thought that I was living in such filth on my tile and area rugs. (6) I have read about people complaining that the Roomba is very noisy. I don't think it's anywhere nearly as loud as a regular vacuum, especially when its running on carpet. Overall, I am very happy with this purchase. While I would not say this is the end all be all of vacuuming, I think it definitely helps keep my house clean and dramatically reduces the need for me to to manually run a vacuum. Less time cleaning = more time having fun...and that I love!

    Comments about iRobot Roomba® 870:

    When I received my Roomba 870 I got it all set up and set it on the charger. I have had a Roomba before, it was a discovery model and it was noisy, battery needed a longer life. So last year I finally cut ties and recycled her. Then I got this great chance to get one from Roomba at a steep discount to try their product. I have to say I am back on the Roomba bandwagon. This new 870 makes about half the noise and picks up twice the dirt for twice as long. It actually gets my living room, dining room and hallway done before it goes back to home base. I also like the newly designed and much larger waste bin. It seemed like I had to empty the old one out before she was done in one room. This 870 does 2 rooms and a hall without filling all the way up. Overall great product. Thankful for the discount.

      As a father of 4, we use the Roomba very often to clean up after the kids. Its such a nice feeling to see a completed room and empty the Roomba bin. I love it and can't stop talking about it with my friends and family. It is truly awesome!

      I love Herbie! Ever since I used it for the first time, I am so happy I spent the money. My carpet has never looked better, and all I have to do is dump the bin when it's full and clean the filter once in a while. I was doubtful because I have two small indoor dogs, but it picks up their hair like it's nothing. I'm thrilled with it and highly recommend.

        Comments about iRobot Roomba® 870:

        I received my Roomba 870 series for an honest consumer review with a discount provided by iRobot. I have now had the roomba for exactly 4 weeks tomorrow and it arrived the day after I had surgery. My restrictions were no vacuuming so I became enamored with my Roomba right away. I have spent the last month paying close attention to the detailed selling points iRobot uses on their video on this website. Cliff Detect, Clutter Navigation, Anti-tangle, Light Touch, Soft Touch, Persistent Pass, Wall Follow, and Escape Behavior. I have done "set-ups" to test these features and each time Roomba has passed my expectations. The only thing I can say is you must empty after each use especially if you have a schedule on it. I think the buttons and sub prompts for menus are easily understood. I have to empty 2x if I allow Roomba to do entire home of 2100 sq ft. Also keeping hepa filter clean for use is important. I would recommend purchasing extra hepas and whiskers.

        We use the Roomba® 870 in our kitchen and family rooms which are the areas my toddlers do their most damage. Our are is marbled floors so I don't know its performance on carpet but for us it to my suprise works really well. We have lots of obstacles (toys, chairs, etc...) in our kitchen/family room and the Roomba navigates the area well. It cleans up our area so well, there a few hard to reach corners that it can't get to but overall does a pretty good job and saves me the hassle of vacuuming everyday with all the food my little monsters drop. Would be nice if they can integrate the wet mopping function they have into one unit which is something I would be very interested in since my toddler's not only drop food but juice too.

        We received iRobot Roomba 800 series discount from iRobot.com. My wife and I really love it. Performance wise it is highly rated – we love how this robot performed on all types of indoor surfaces such as carpet, hardwood, tiled and linoleum flooring but they mentioned that you shouldn't ditch the full sized vacuum just yet and they did question if you should invest this much in a robot for a simple task for vacuuming. But for those busy folks who can afford it, it is a smart buy.

          I love my new Roomba® 800 seriesI use it everyday. At first i was having to empty quite often this was because it was vacuuming in places I could have never reached with a normal vacuum (like under our beds). But now after having used it for a few weeks I only empty after it finishes. It is amazing how much cleaner my floors are!!!! I couldn't be more pleased! Thank you iRobot for the amazing discount!!
