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:

Things that still needed work.
- The unit still finds itself trapped underneath furniture when there's wires. It would get entangled and because of the low clearance, it's unable to lift itself up above the wires. Thin wires would sometimes get sucked up into the brush heads.

- It's able to find it way into a situation/area but then it gets trapped. The unit would vacuuming into an area but when it tries to get out, it can't find the exit. Better algorithm to mapping a room it just vacuumed.

Great things about the Roomba 870
- Definitely took care of the need for every day vacuuming. Cleaner floors, rugs, carpets. Much less dust on the floors.

- We have a 7-year old who's not the cleanest when it comes to eating snacks and would sometimes leave crumbs on the floor. We know the Roomba would come pick it up when it does its schedule run.

Comments about iRobot Roomba® 870:

I hate to admit this but one of my favorite morning rituals now is emptying the Roomba tray (Roomba's equivalent of a vacuum bag). I have no idea how, despite a pretty good discipline of taking our shoes off before entering our house, so much darn dirt gets trapped by our little Roomba.

Honestly, how do people live without a Roomba anyway? No, it doesn't replace a bi-weekly cleaning for us. But there's a special pleasure in life to waking up every morning to clean floors and those zig-zagged Roomba patterns on our carpets. Especially in a family of 6. But I'll still want one years from now when we're a family of 2.

I had a previous version of Roomba before getting the 870. The big difference is that the new Roomba picks up a lot more dirt. Just to demonstrate the point: The day after our bi-weekly cleaning, our Roomba tray still had a ton in it. I don't know whether to fire our cleaners or tell them to start using our Roomba instead.

It seems especially effective on our tile floors where the previous Roomba would sometimes just shoot dirt to another part of the house. The new Roomba brush also seems to require a lot less maintenance.

Biggest complaint about the Roomba 870: It's too expensive to justify one for each part of our house. ;) (And I got a Roomba upgrade with a discount from iRobot.)

    I received a discount from iRobot to trial the Roomba 870 as part of the BzzAgent team. I love that I no longer have to clean the floors and it does a better job than I ever did. It picks up all the sand and hair from the dog as well as other dirt. I love that it has these little brushes that extend from the edge of the machine that sweep dirt from hard to reach corners and edges, then sucks it right up into the vacuum. I am no longer a slave to my floors.

        I just recently took out my old vacuum to compare and contrast with the Roomba, and quite to my surprise, the iRobot Roomba870 actually picks up the cat fur, dust, hair, and cat litter BETTER than my conventional vacuum! The only thing I use my conventional vacuum for now is my stairs... Can't wait for them to create a model that can climb! This product is worth EVERY PENNY!

        Thanks to IRobot and the awesome discount, I was able to purchase this phenomenal product. It is very easy to set up and takes away long back breaking hours of sweeping. The only thing that kind of annoys me is the constant noise. But overall, it is a great product and my floors will be cleaner because of the I Robot Roomba 800 series. Totally recommended!

          I love my iRobot Roomba 870. It works great on my hardwood floors, tile and carpet. The transition between surfaces is flawless.
          I especially love that it gets under my beds and furniture. No more trying to get all the dust bunnies for me! My robot does it!
          It is a bit expensive. (I did get a iRobot Roomba 800 series discount from iRobot, so that helped a lot.) However, if you compare it to the cost of a Dyson, it is comperable and, unlike Dyson, it does the work for you :)

            I was able to purchase this as part of a product review for BzzAgent. This product saves me so much time during the week. It is perfect for picking up the pet hair from our two dogs during the week. Because it can't do stairs and isn't great about getting in corners, behind does or furnitue I still vacuum with an upright on the weekend. I have noticed that since the floors are being swept daily or rugs are looking nicer between washing and there is less dog hair in our house in general. I love that it does it's thing and then docks itself without having to follow it around or use a remote. The virtual walls are a lifesaver too. We have stairs and dog bowls we need the Roomba to avoid. Everything else needs to be picked up. The Roomba doesn't get caught on or tangled up in much but of course it won't clean a spot if something else is already there. Its pretty good about sensoring walls and furniture but does bump in to a few things.
