iRobot Roomba 770 vs 880: An In-Depth Comparison

iRobot 770 Review An Impressive Automatic Vacuum RobotiRobot Roomba 770 vs 880Our in-depth comparison of the iRobot Roomba 770 vs 880 models will go through all of their similarities and differences.

These robotic vacuum cleaners may appear identical on the surface but they are in-fact quite different.

iRobot’s Roomba 880 has improved on the 770 in several key areas including its motor, extractors, battery, and virtual infrared sensors.

Although the 880 is significantly more expensive than the 770, we believe that you’re getting a vastly improved product that’s well worth the money.

Let’s see how these Roomba vacuums match up.


Battle of the Roombas


  • iRobot Roomba 770 ScheduleThe 770 and 880 both come with the ability to program a 7 day operation schedule. The buttons on the top of the unit allow the user to set the robot vacuum’s schedule or begin a cleaning session.
  • iRobot Roomba 770 TransferBoth of these robot vacuums are capable of cleaning a myriad of floor surfaces including carpet, rugs, tile, laminate, hardwood, as well as others. When switching between different types of floor materials, they will automatically adjust to account for that particular surface.
  • iRobot Roomba 3 stageThese vacuum cleaners use iRobot’s 3-stage cleaning system which consists of agitation, brushing, and use of high-powered suction to clean your floors.
  • iRobot Roomba 770 CleaningA side brush protrudes from the bottom of these robotic vacuums to get into areas that the Roombas can’t pass over because of its shape. This spinning side brush does a very effective job at getting into areas such as corners and along moldings.
  • Dirt Detect Series II Technology is present in both of these iRobot vacuums. This technology consists of optical and acoustic sensors to detect areas that are dirtier than others. These vacuums will spend more time cleaning these areas as a result.
  • iRobot Roomba 880At only 3.6″ in height, both of these automatic vacuum cleaners can get beneath your household furniture to clean areas seldom cleaned by conventional vacuums.
  • iRobot Roomba 770 StairsThese vacuum cleaners are equipped with sensors to tell them when they are by a hazardous area like stairs. They will automatically stop and turn around so they don’t fall over.
  • Objects within these Roombas’ vacuuming area are automatically accounted for using the integrated iAdapt Responsive Navigation System. These robots can create an efficient path around these objects as a result.
  • iRobot Roomba 770 Virtual WallIncluded with both of these models are virtual wall infrared sensors which provide artificial barriers for the Roombas so they do not enter rooms that you don’t want vacuumed.
  • iRobot Roomba 770 RemoteThe 770 and 880 both come with remote controls. These remotes can be used to alter the Roombas’ settings or to manually control them.
  • Lastly, these Roomba vacuum cleaners automatically return to their charging station when they detect low battery or have completed their scheduled cleaning session. In the event they run out of battery prior to completing their session, they will resume cleaning once recharged.



  • Present in the Roomba 880 is a new motor that iRobot states provides up to 50% more cleaning performance and 5 times more power. They also note that this motor is much stronger and less prone to failure.
  • iRobot Roomba Side BrushAnother upgraded feature of the Roomba 880 are its new extractors. Rather than using a brush like the 770 and prior models use, the 880 uses a set of rubber extractors that are able to remove dirt and debris better. These extractors are also able to transfer debris into the collection bin much easier which reduces issues with tangled hair.
  • The Roomba 880 now uses a new lithium ion battery which replaces the nickel–metal hydride battery used in the 770 and prior models. This battery has the same life as its predacessors but can now be charged twice as many times before needing replacement. This is a substantial savings over the life of the vacuum.
  • New to the Roomba 880 is the use of infrared virtual wall lighthouse sensors. Although these sensors can also act as a barrier as seen with the 770, their lighthouse capability allow for efficient multi-room cleaning. They prevent the Roomba from going into other rooms before the current room has been thoroughly cleaned. It will be contained within a specific room for a while before being permitted to go into the next where it will be trapped there for a while and so forth.
