  • A cordless vac for general mess and pet hair as well
  • Converts to a handheld vac from an upright vac for both floor and ceiling cleaning
  • The regular version comes with one Lithium ion removable battery, and the 2X comes with two batteries
  • Removable batteries means you can charge one and use the other, then alternate
  • It has 2 speeds for both floor mode and carpet mode
  • It has a max speed, and also has an extend run time setting
  • DuoClean means it has two brushrolls instead of one
  • MultiFLEX Technology folds over for compact, free-standing storage and provides flexible reach to get under beds, couches, and tables.
  • Smart Response Technology provides a range of performance-enhancing power settings, tailored for your cleaning needs on carpets and floors.
  • The vacuum is lightweight at around 8.7lbs
  • Has LED headlights for better visibility
  • Has washable foam filters
  • Vacuum comes with Duster Crevice Tool, Pet Multi-Tool, ION Power Pack Battery or Batteries, Charging Cord, Charging Dock, and Anti-Allergen Dust Brush


  • Dust container capacity could be bigger at 0.3 dry quarts
  • Run time could be better for the battery – lasts between 10 to 20 minutes
  • Because of the run time, the vacuum is more for smaller areas than larger areas
  • Not as good on thicker carpeting and for picking up pet hair as other vacuums – a corded vacuum might be better
  • Battery capacity and power can decrease over time
  • Vacuum is not cheap


  • Overall, the vacuum is good, but maybe not quite worth the money it is listed at. It’s best as a vacuum for bare floors and shorter carpets where it can pick up mess on the surface, rather than deep down within fibres. It’s also better for short cleans and small areas rather than extended cleans and big areas. Read the return policy and warranty conditions before buying to cover your money investment.
