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.

        - even my husband does not mind "vacuuming" now. He has heart issues and could not vacuum before. I have a bad back and it gets under beds and couches so much better than I ever could. I had a 550 Roomba for some time and just "upgraded" to the 870 - it is wonderful.

          The last Roomba Scheduler 300 series I owned since 2007 gave up summer 2014. The Roomba 870 that I now use to clean my living room carpet of dog hair is far more powerful and efficient at picking up the hair and dust. I can vacuum with my heavy duty vacuum one day and the next day the Roomba will still pick up dirt that the upright missed.
          What I learned from my first Roomba is that they need constant maintenance to function properly. Besides emptying the bin, it is necessary to follow all the steps for maintenance often. Do that and you will enjoy your "helper" for many years.

            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.
