There is a significant difference between the two in the controlling interface: in the shark IZ201UK cordless vacuum, a three-mode sliding switch at the fingertip allows you to turn on/off the power and adjust the floor’s type. You can change the cleaning mode from hard surface to carpet surface by just sliding the switch positions. To adjust the suction power of the shark IZ201UK, it has a trigger switch under the handle; you need to pull the trigger switch for maximum suction. On the other hand, the shark iz300uk has a LED display that shows how much battery charge has left and the selected suction power and surface type. PowerFins technology:

The difference between floor head design: The shark IZ300UK featured a Powerfins brush roll instead of the stiff bristles. There are stiff bristles around the barrel in a standard brush roll, the same thing you’ll notice in the shark IZ201UK. Additionally, the shark IZ201UK brush roll design is different from than standard. There are silicon fins at the gap between the bristles; shark’s named it the anti-hair wrap brush roll system. Two cordless vacuums are visually similar, and their performance on cleaning carpets, hard floors, and pet hair were closely similar.
