One of these models is the iRobot Roomba 850 Robotic Vacuum Cleaner, which is a vac that can be used on both carpets and hard floors, and can also be scheduled for cleaning.

In this iRobot Roomba 850 Robotic Vacuum Cleaner Review, we look at the main features and potential drawbacks to this robotic vacuum so you can get a good idea or not whether it’s worth your money.

It’s worth noting the newest model Roombas are out now which include the 800 and 900 series’. You can check them out in this Roomba comparison guide.

Let’s take a better look at the 850!

  • There’s the new model 800 and 900 series Roombas out now, which have increased power and newer features an technology
  • Doesn’t have mutli room navigation, iRobot Home App, recharge and resume feature, or carpet boost
  • Not a cheap vac
  • Can sometimes mark wooden room trim around the outside of the room if you don’t have the wall barrier set up and working properly
  • Doesn’t clean in lines – cleans in a random pattern – so can miss some spots and go over other spots more than once
  • Some people prefer an electric upright vac which is more powerful, has a bigger capacity and cleans more thoroughly
  • More for lighter messes and lower amounts of dog hair – not as much for very heavy cleaning and large amounts of dog hair (or long hair)
  • For flatter surfaces and lower pile surfaces – may struggle on very thick/plush carpets, and steep changes in floor levels


  • Overall, the 850 is quite good as a light duty robotic vac, but it does lack some of the features the newest models have. If you do want the 850 though, read the return policy and warranty conditions before you buy to protect your money investment.
