The Shark Rocket IX140, IX141 and Shark Rocket Pro IZ140 are battery powered stick and handheld 2-in-1 vacuum cleaners.

The difference between them are as follows:
Nozzle
The Shark Rocket Pro IZ140 features a self-cleaning brushroll with Dirt Engage floor nozzle whereas the IX140 and IX141 have a standard floor nozzle.
According to Shark, if any hair wrapped around the self cleaning brushroll, continue cleaning will allow the brushroll actively removes pet and human, long and short hair from the roller. The Dirt Engage technology delivers direct contact on hard floors, helps remove stuck-on dirt; and brushroll digs into carpets and picks up embedded debris. The standard nozzle does not have these features.

Wand
The IZ140 comes with a MultiFLEX Wand whereas the IX140 and IX141 have a standard wand.
The MultiFLEX Wand can be bended to get under low furniture, and makes the vacuum able to stand on its own for neat storage. The standard wand will not bend, you have to lean it against something to make it self standing for storage.

Headlight
The IX141 has headlights on the nozzle to illuminate dark areas in front, while the IX140 and IZ140 do not have headlights.

Battery
They use a 21.6V lithium-ion rechargeable and recyclable battery. The battery can only be charged in the vacuum, it is not designed to be detached for charging, you cannot use an additional swappable battery for quick changing if it runs out of battery.
The vacuum cleaners can work approximately 10 to 40 minutes depends on the which modes you choose.
When using without the nozzle as a hand vacuum, it has standard mode for general cleaning jobs and boost mode for tough tasks. The vacuum runs approximately 40 minutes in standard mode and 10 minutes in boost mode.
When using with the floor nozzle, you can choose Bare Floor/Area Rug setting or Carpet setting. In Bare Floor/Area Rugs setting,
the brushroll spins slowly to clean bare floors and small area rugs.
In Carpet setting, the brushroll spins faster to clean carpets. The vacuum runs approximately 25 minutes in Bare Floor mode, 20 minutes in Carpet setting. You can also pull the Trigger
on the handheld vacuum for an added boost in power. However, this drain the battery fast.
It takes approximately 3 hours for a full charge.
The vacuum cleaners have LED power and charging indicator near the handle to show you the battery status.
If you also consider a corded stick model, you can have a look at the ZS362 and LZ602, both of them are corded, equipped with a larger dust cup, and feature dual rollers with self-cleaning brushroll, and the LZ602 can even stand by its own.

CleanTouch Dirt Ejector
All of them feature Shark’s CleanTouch Dirt Ejector which allows the users to empty the dust bin without getting hands dirty.
The wand needs to be removed to empty the bin.

These two Shark vacuum series are similar, they have similar features, specifications, pros, cons. The biggest difference is the brushroll design. The Shark Apex DuoClean with Zero-M Stick Vac ZS360/ZS362 feature the DuoClean technology that the Shark Rocket Zero-M Ultralight Corded Stick Vacuum ZS352/ZS351/ZS350/HV345 does not have.
The DuoClean technology has two brush rollers inside the floor nozzle: besides the bristle brushroll, there is an additional soft roller at the fore to tackle stuck-on dust and large particles on both carpets and hard floors.

Since the Apex DuoClean have 2 rollers, you have dual rollers to clean. The good thing is the brushroll garage cover is on the top of nozzle,and you just need to slide 2 release button to open it. The bristle brushroll is not detachable while the soft roller can be removed to clean.
On the other side, the Rocket Zero-M has only the bristle brushroll to clean,but the brush cover is at the bottom of the nozzle, and you have to unscrew 3 screws to open it and clean the brushroll which is also not removable.

Another difference is the motor:
The Apex DuoClean with Zero-M has a 600 watt, 5 amp motor whereas the Rocket Zero-M has a 500 Watt, 4.2 Amp motor

Similar features and facts you may want to know:

They do NOT stand by themselves.
Just like most stick vacuum cleaners on the market, they don’t have the ability to stand by their own. So, when you want to stop to do anything else, such as changing outlets, taking a break, answering a phone call, you have to lay it down. Hate this? Have a look at the Shark Apex Uplight which is a corded stick vacuum that stands on its own

Both Feature Zero-M Technology

Does the brushroll really clean itself?
You will get conflicting answers from users, you can read users reviews at Amazon here.

LED Headlights
They have led lights on both floor nozzle and handheld part. The lights do help vacuum dark spots and reveal hidden debris.

No HEPA Filter
For those who are looking for a slim vacuum with HEPA filtration, these are not your choices. You may want to take a look at the Shark Apex Uplight which has Anti-Allergen Complete Seal system with a HEPA Filter, it would be a better choice for asthma and allergy sufferers.

No Adjustable Suction Control
They do not allow users to adjust the suction power for different needs.

No Brushroll On/Off Control
They have 2 surface settings: Bare Floor/Small Area Rugs setting with the brushrolls spinning slowly and Carpet setting with brushrolls spinning faster.
The brush rollers keep rotating in both of the two modes when using the floor nozzle to vacuum.

2 in 1 design
They both can be used as a stick vacuum as well as a handheld vacuum. The floor nozzle can be attached to the handheld portion without the wand for more versatile cleaning.

Low Profile Nozzle
They can get underneath furniture with an approximate 5-inch clearance and higher.
