  • A robotic vacuum that can be used on most floor types – carpets through to hard floors
  • Has AeroVac technology for suction
  • Has Dirt Detect technology that senses where debris and dirt are
  • Has Wall-Following cleaning technology to clean and sweep along walls and edges
  • Has an Anti-fall sensor and an anti-impact sensor
  • Has anti-tangle technology on the vacuum brushes when dealing with pet and other hair
  • Automatically returns to it’s dock for charging,
  • Has iAdapt technology 
  • Has three-stage cleaning to dislodge, lift and clean up debris and hair
  • Allows you to press the ‘clean’ button on the vacuum for automatic cleaning without any programming
  • Is a bagless vacuum with a dust container and no bag to empty
  • Comes with a battery charger, self-charging Home Base and lithium ion battery
  • Warranty for Roomba vacuums is a 1 year limited warranty including the battery


  • There are newer and better model Roombas out for better value when you consider their price that allow extra features like cleaning scheduling and better App integration
  • Not cheap
  • 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, we would skip the 620 and go straight for the newer 690, 890, 960 and 980 models which we think offer better value. If you still want the 620, read the return policy and warranty conditions before you buy to protect your money investment.
