In this comprehensive comparison article, we delve into the world of Shark cordless vacuums to explore the key differences between the Shark WZ140 vs IZ140 models. Let’s get started.
The Shark IZ140, our top pick in this matchup, boasts an impressive array of features that set it apart from the competition. One notable highlight is the inclusion of the MultiFLEX wand, a groundbreaking innovation that allows the vacuum to effortlessly bend for under-furniture reach, providing access to those hard-to-reach areas that often accumulate dust and debris.
While the Shark WZ140 is our runner-up in this comparison, it still deserves recognition for its noteworthy features and performance. This model excels in maneuverability, making it a breeze to navigate around furniture, corners, and other obstacles during cleaning tasks. Its user-friendly design ensures effortless movement, providing a seamless cleaning experience.

Shark WZ140 Vs IZ140: Differences
After undergoing multiple tests, Shark IZ140 emerged victorious with a score of 1-0, having only tied once against its rival, Shark WZ140. Despite their many similarities, the former stood out with superior cleaning performance. It was a closely contested battle nonetheless.
Cleaning performance
The winner: Shark IZ140
In evaluating the cleaning performance of both the Shark WZ140 and Shark IZ140, I embarked on a detailed analysis that took into account several factors.
First, I tackled the bare floor vacuuming capabilities. The Shark WZ140 exhibited commendable prowess in this domain, picking up approximately 95 percent of visible dust and dirt. This was impressive, although I found it a little less effective on carpets in bedrooms – a situation remedied by my existing vacuum.
However, one recurring issue I experienced was that it tended to clog and unclog quite easily. Despite this, it showed proficiency in dealing with the edges if approached from the right angle, a valuable trait in tackling pet room mess.
In contrast, the Shark IZ140 portrayed strong suction capabilities, making it well-suited for large amounts of dirt and debris. It also performed effectively on carpets without disrupting the nap, which was pleasing. However, for deeply embedded dirt, I noted that more time and effort were required for deeply embedded dirt, going over the same areas multiple times. This trait also manifested when dealing with rugs, necessitating multiple passes to attain satisfactory cleanliness.
Both models boasted an appealing feature – the ability to combat hair entanglement around the brush. Yet, as I evaluated this claim, my experience suggested that while it held true for the Shark IZ140, it was slightly less effective in the case of the Shark WZ140. I observed some hair still wrapped around the WZ140’s brush, albeit lesser than most vacuums.
It’s challenging to make a blanket statement about the superior model since they each have strengths and weaknesses. Yet, I am slightly leaning towards the IZ140 due to its commendable overall performance, especially its prowess in hair collection, a trait of significant importance in a vacuum cleaner.
Design and convenience
Tie!
Weight and dimension
In my in-depth analysis of the two potent Shark vacuum cleaners, I found several striking differences that warrant keen attention. The Shark WZ140, with its dimensions of 14.96 x 10.24 x 46.06 inches, is slightly larger than the Shark IZ140, which measures 10.00 x 7.00 x 46.00 inches. Despite their variances in size, it’s quite surprising to note that they both weigh the same, a mere 7.5 pounds.
When contemplating their physical attributes, one might question the consequences of these differences in cleaning performance. As an expert in this field, I considered this with the same gravity. Observing the WZ140, its increased breadth and depth provide a broader cleaning path, which proves beneficial when dealing with larger cleaning areas.
But don’t let the smaller dimensions of the IZ140 deceive you. While it’s less expansive in its reach, its compact design offers enhanced maneuverability, making it a splendid choice for more intricate spaces.
Battery
The WZ140’s battery performance was acceptable, albeit with a twist. Should one engage the turbo feature, the battery drains rapidly, causing a need to pause halfway through cleaning for a recharge. This is a peculiar challenge for a modest two-bedroom abode that can be vacuumed entirely in half an hour.
Consequently, maintaining a backup battery and an extra charger could be essential with this model. A fully charged WZ140 lasted for around 25 minutes in my testing, not an impressive feat when compared to industry standards.
Conversely, the Shark IZ140 had its own set of peculiarities. The battery life ran for approximately 20 minutes, marginally less than the WZ140, but exhibited a concerning overheating trend after vacuuming a standard-sized living room. This tendency could potentially indicate a longer-term issue.
It’s also worth mentioning that there were some minor hiccups with the charger function for some users. However, with the provision of a 5-year warranty, there is a level of reassurance regarding any potential technical issues.
The charging time for both models hovers around 2 hours, a tie in this particular metric.
Maneuverability
Regarding maneuverability, the Shark WZ140 offers good mobility, making it easy to move around during cleaning tasks. In addition, its design allows for smooth navigation, enabling users to reach different areas without effort effortlessly.
On the other hand, the Shark IZ140 takes maneuverability to the next level with its MultiFLEX wand. This innovative feature bends, providing convenient access to hard-to-reach places, especially underneath furniture. Additionally, the wand can be folded for compact, self-standing storage, optimizing space efficiency. This is a practical advantage for those with limited storage areas.
Comparing the two models, the Shark WZ140 offers solid maneuverability, ensuring ease of movement, while its rival takes it a step further with its flexible wand and compact storage capability. Assessing individual cleaning preferences and storage requirements will help determine which maneuverability feature aligns better with specific needs.
