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:

    We purchased our Roomba 870 with a discount from iRobot, and are very pleased with the product performance. We have a dog who sheds, and being able to run the Roomba frequently on a programmed schedule helps us keep our house cleaner. The Roomba was easy to use straight out of the box (after charging of course) and provides excellent cleaning. We especially like how it can get under furniture like beds and coffee tables where we don't usually vacuum. It does occasionally get stuck in some corners or under an uneven surface, but in general it moves around the house efficiently, cleaning all the way. And then when it is finished or needs to recharge, it makes its way back to the charging station. What could be simpler?!?! When we first purchased it I was thinking how much time/effort can this really save us? But it really, really does. Being able to do some other chore (or maybe even something else fun!) while Roomba takes care of the vacuuming really does give us back some of our precious time.

      Comments about iRobot Roomba® 870:

      I received a discount for this product from iRobot. Let me just say, it has changed my life! I just put it in the room I need vacuumed, shut the door and come back later to a clean room! It's easy to use as well as easy to clean and maintain. My only slight critisism is that it's better in a closed off space or room. Our downstairs is an open concept floorplan and even with the invisible wall there is no way to "wall" off just a portion of the downstairs. So the vacuum has to do the living room, kitchen, dining room and hallway. Occasionally when it thinks it's done I have to get it back out to have him go over a portion again. It's just a really big space. That being said, that's rare, it usually does a great job. When you put it in an enclosed room it's simply amazing. Imagine shutting the door and walking away, only to come back an hour later to a spotless room. The dust that came out from under beds, couches, chairs, etc. is amazing (and disgusting!) Once it got under those areas though the cleaning process is faster and not quite so gross. My daughter and I both have long hair and not only does it pick up all the hair on the ground, when it comes time to clean the vacuum it slides right off the extractors. I didn't believe this until I saw it. Also, with 2 small kids I was worried about toys left on the ground being sucked up. It will pick them up but they are easy to fish out of the bin when you empty it. It's amazing the suction power this vacuum has! It's well worth the price tag.

      Comments about iRobot Roomba® 870:

      ehhh....I expected so much more when got a discount for my Roomba from iRobot. I really thought it would blow my socks off but I was a bit disappointed. I have a 1 year old who is always dropping crumbs all over the house and i figured this would solve most of that without me chasing her around with a dust pan but it seems that it kept missing whole spots on the floor and i found it didnt clean the carpets wel. Very sad :(

        Really enjoy this and never would have realized that our carpet was as dirty as it is. Went from vacuuming every other week to now 1-2 times per week in each room. The only thing I wish the Roomba could do is my stairs. I also wish it was a little better on tile. But this is great, better than I would have imagined.

            Comments about iRobot Roomba® 870:

            Here's the deal, I've always been in the mindset that robotic vacuums and their non-robotic counterparts are not one in the same. Although the 870 is an improvement over other cleaners I've had, it still has some of the drawbacks that they all share.

            Let's begin on where this one gets it right. It's quiet! Sneakily quiet. You'll know it's running, but it's honestly not distracting. Also, the fact that it's self-charging and has ample battery, means that I don't believe I'll see this thing dying mid-task.
            Also, this thing seems built very well.

            That leads me to the downsides. It only has a one-year limited warranty, which is scary when your vacuum costs as much as this one does. Also, you have to make sure your floor is basically ready for the Roomba. This means making sure that the floor is clear of small objects including cables. This might be a good thing anyway, but it's worth noting.

            Also, a big limitation is you'll be needing to empty the dirt compartment after each use. This is the bummer because if you still have to do something each time you use it, what's the point of having a robot right? Well, the thing is, is doesn't take very long and it's the nature of the product right now. All robotic vacuums are too small to keep and carry a large payload. It would be too much on the battery and make the unit larger. On the bright side, if you have pets you WILL see the pet hair this thing is picking up.

            As soon as they make this thing take out it's own trash, they can raise the price by 50%.

            I'd like to add that I received my 800 series Roomba at a discount from iRobot.com.

                I use this product to help control the pet hairs that are always around. I love that it fits under most of my furniture to get all the dust bunnies. Thought my dogs would be scared but they are not.. So glad I received a discount thru bzzagent to try this product. It doesn't go in a straight line or vacuum like I would but if I let it run it does get the entire floor.

                I recently purchased the Roomba 870 series vacuum when I received a discount from iRobot and we are very satifsified in our household with the great job it does. We primarily use the vacuum in our house which contains hardwood floors and tile throughout. I was skeptical at first about dirt being 'pushed' around like my other vacuums tend to do on hard flooring, but have been pleasantly surprised at how great a job it does a picking up the debris and not just relocating it. Since we have a dog in out house, hair shedding has always been a number one issue, and this device really does the job at keep the excess fur at bay. The only downfall I have is that it is not compatible for the optional lighthouse guides like the other series have. We have many rooms and smaller spaces, I think those would have helped guide the machine around with a little more ease. Overall, very pleased with the vacuum. Wish I had this sooner in life, I enjoy my free extra free time from daily vacuuming!
