  • Both models the same design and technologies.
    They are cordless stick vacuum cleaners using Li-ion battery (similar to Hoover REACT cordless and Dyson battery) which can last for up to 23 minutes on low running mode.
  • The Duoclean technology 
    Shark Ionflex models use Shark new technology in brush head design for recovering more dust and pet hair from carpets (a bristle and a soft roller – Duoclean technology). The Duoclean technology is the most appreciated brush roll design, because it can efficiently pick up embedded pet hairs on carpet and area rugs, and at the same time pick up larger particles easily.

    Moreover, they have a bending wand which is flexible for cleaning furniture and for storage. You can read Shark ionflex reviews here to see all of the benefits of this series.
