The main difference between Shark Vertex Canister Vacuum CZ2001 and Shark Pet Canister Bagless Corded Vacuum CZ351 is the brushroll system.
The CZ351 uses Powerfins whereas the CZ2001 uses DuoClean Powerfins.
The Powerfins uses flexible silicone fins to replace the traditional bristle. According to Shark, the Powerfins provides continuous cleaning contact, digging deep into carpets and directly engaging floors; it is designed to pick up more with less hair wrap problem when compared to bristle brush, and unlike a standard bristle brushroll, there are no gaps, thus less dirt may be missed.
The DuoClean Powerfins has one more roller in the nozzle, so the DuoClean Powerfins system has two rollers, a Soft Roller and the Powerfins Roller, work together in the nozzle.
The soft roller helps pull in large particles and fine dust without pushing them away, gives a polished look on floors.
Other difference is the color and price.
The CZ351 is Navy & Silver whereas the CZ2001 is Black & Copper.
The CZ351 is cheaper than the CZ2001.
