images from manufacturer

  • The Roomba 880 comes with 2 Virtual Wall Lighthouses while the 870 comes with 2 Virtual Walls, and the 870 is NOT compatible with the Lighthouse.
    The Virtual Wall Lighthouse has 2 modes including Virtual Wall mode and Lighthouse mode. The virtual wall mode stops the Roomba from entering off-limits areas while the Lighthouse mode helps navigate the Roomba vacuum from room to room, it firstly contains the Roomba in one room before that room is cleaned, and then guide it to vacuum the next room.

  • The Roomba 880 also comes with a Remote Control while the 870 does NOT include.
    The Remote Control allows users to control Roomba without touching it, such as turn on/off the Roomba and steer it around.
  • Other difference are the Color and Cost. The 880 is darker; the 870 is $100 cheaper than the 880 that is priced at $699.99 on irobot.com

    • Some Same Features:

  • AeroForce Performance Cleaning System: Tangle-Free AeroForce Extractors to grab dirt, and the Airflow Accelerator and High-Efficiency Vacuum draw and pick up dirt.
  • Schedule Feature: allows you to preset cleaning times, up to 7 times per week.
  • The Roomba can Self Docks And Recharges
  • Feature the Dirt Detect Series 2 Technology with Persistent Pass Cleaning: use both acoustic and optical sensors to find dirtier spots and spend more time cleaning there.
  • Wall-Following Technology with side brush to vacuum along baseboards and edges.
  • Cliff-detection sensors to avoid drop-offs.
  • Use iRobot XLife Extended Life Battery to double the battery lifespan.
  • Have soft-touch bumper to protect furniture and other objects.
  • iAdapt Responsive Navigation Technology that help navigate the Roomba to clean your home thoughly.
  • Equiped with HEPA filter to keep your home air clean.

    • Overall, deciding between these 2 Roombas is about cost and more functions.
    1, you spend extra $100 to get the 880 with Lighthouse function and Remote Control.
    2, you save $100 to use the 870 without Lighthouse and Remote Control.
    In fact, the Remote Control is not a useful kit. Many Roomba users do not use it even they have it.
    If you have a large house, then the Lighthouse will be useful.
