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.

  • Stuck Under Couch

Best Uses

  • High Traffic Rooms

Comments about iRobot Roomba® 870:

At first, a miracle. More lately, we have found it stopped a couple of times and reality has set in: there are no miracles. Once it got stuck on a string bag my kids left on the floor, and more than once it has been pinned under the couch where the sag is gradual so the bumper can't detect an obstacle. That said, the bin picks up an incredible amount of pet hair and dust bunnies and lets be honest, we are no longer vacuuming our house.

Comments about iRobot Roomba® 870:

I purchased the Roomba 870 as a Christmas gift for my mother. Now I know what many of you may be thinking, but when I showed my mom how it works, and she saw how much dust she wasn't getting with her traditional means of cleaning she quickly fell in love.

Traditional ways of cleaning your home can't hold a candle to what the great people at iRobot have been able to achieve. This gets every spec of dust, nothing is left behind, and the unit is extremely thorough.

There are a few instances where the machine jams up because the rug is too large, or it gets caught under one of our coffee tables which is low, but aside from that I've never had any issues. The unit cleans, and it cleans well!!!

We don't have pets or carpeted rooms, just carpets. It works great on carpets, it just jams up when driving off our carpet which is pretty thick.

People don't believe how clean my house is, and they believe it less when I tell them it's because of my mom's Christmas gift. If your mother is in her mid to late 50's, and planning on retiring this is a great gift! If you're single, and question how you find time to sleep... this is perfect for you!

Everyone in my household works, and we all love Lucy. I was skeptical at first of course, but I embrace technology, and once my mother saw how effective our Roomba is, she quickly named her Lucy. It's an odd but great, thoughtful gift. I'm not saying get this for your girlfriend, unless you think this will really be useful, but my whole family loves it as do our guests.

WARNING: Don't leave cables lying on the ground, the roomba will vacuum them up!

      Comments about iRobot Roomba® 870:

      This robot has returned peace to our household. Our dog shed's two times a year and we live out in the country where there is a lot of dust and pollen. The filter helps with all the dust. The dog is not a nuisance anymore due to the hair floating around the room and settling under the furniture. Rudy does his daily cleaning while we sleep and we come down to a shiny floor in the dining and living area of the the house. Absolutely amazing.

      Comments about iRobot Roomba® 870:

      We use this for hardwood floors, area rugs and tile - it is great on everything but the cheaper kitchen mats which it can't pull all the pet hair from. It is so great to leave the Roomba to do the work as I'm off to work. We are so very happy with it and hardly use our other vacuum now.

      Comments about iRobot Roomba® 870:

      I've spent a lot of time watching this to figure out how it "thinks." While it does give pretty good coverage, it will miss spots in larger rooms. My basement is very large and open, but the Roomba almost entirely misses the section near the stairs no matter where I start it. One reviewer stated that you need to prep the room, and I've found this to be true. It seems that the fewer turns and bumps it needs to make the faster it will clean a room, and the battery will last longer.
      I would recommend that you confine it to single rooms when you first get it, and let it completely clean those rooms one at a time. We have found that after a while the bin doesn't fill up nearly as fast, so it makes it further and cleans more. I do wish that it could map the house, go back and recharge, and pick up where it left off.
      While I think there are some improvements that could be made I have to say that our floors have never stayed this clean. It's nice coming home and not seeing dog hair all over the wood floors. Even if you do have to help it along at times it's still better than doing the whole house manually.

      I'd recommend the 880 over the 870 simply so you can have the lighthouses to guide Roomba around your house.
