What’s the difference between Shark CZ351 vs CZ2001?

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.

Size
The Shark Rotator Powered Lift Away is full size while the DuoClean Speed is compact size.
What makes the full size bulkier is mainly because of the bigger lift away pod and the wider cleaning path width. The Rotator has a dust container holds up to 1.5 dry quarts while the DuoClean Speed has a dust cup capacity of 0.9 dry quarts. The Rotator cleaning path width is 10.5 inches versus 8.5 inches on the DuoClean Speed. The Rotator weighs about 16.7 lbs while the DuoClean Spead weighs 14.5 lbs.

Brushrolls
The DuoClean Speed has 2 brusrolls – a bristle brush to clean carpets, and a soft brushroll to pull in particles and clean hard floors. While the Rotator has only bristle brushroll. When cleaning any blockage, the brushrolls on the DuoClean Speed can be removed while the Rotator brushroll is not removable.

Hard Floor Cleaning Mode
Both of them have 3 preset cleaning modes – Thick Carpet/Area Rug, Carpet/Low Pile, Hard Floor. When setting to Hard Floor mode, the DuoClean Speed brushrolls still spins slowly while the Rotator brushroll does not spin. That means the DuoClean Spead does not allow you use suction only while using the powered nozzle.

LED lights
The DuoClean Speed has lights on the nozzle while the Rotator has lights on nozzle and handle, the LED lights on handle is helpful when cleaning with the accessories for above floor cleaning, especially cleaning those dark spots.

Power Button Location
The DuoClean Speed has the power switch on the vacuum pod while the Rotator has the power button on the handle.

Both of these two series vacuum cleaners have detachable vacuum pod for portable cleaning, features swivel steering, Anti-Allergen Complete Seal Technology and a HEPA filter to trap dust and allergens inside the vacuum.
