I have owned several shark hand held vacums and this new generation model is definitely not an improvement.   It is difficult to empty, does not come with the docking base as older models did but you can purchase separately.   The new (not improved) brushless power brush spits out hair/dirt/dander that does not get sucked up on first rotation unlike like the brush models.   I am not a fan of this product.    Older models are far superior.
