What reviewers didn't like

It’s a little unwieldy in the hand, heavy to reach high cobwebs, and the main floorhead tends to pull forward.
It’s a bit more pricier than the corded Rocket.
The Shark IONFlex is a bit on the pricey side, but it is the best. However, there are definitely better options out there if you are looking to maximize the best bang for the buck.
The IONFlex is a little heavy and needs to be emptied often.
The dust collection bin is small and fills quickly
The Shark ION Flex DuoClean Cordless Ultra-Light Vacuum (IF201) has a tendency to pull itself along like a Self-Propelled vacuum when cleaning carpet. This certainly requires almost no effort for pushing the vacuum forward but it takes some getting used to when pulling it back.
It's on the heavier side of stick vacuums and does not have a brush on/off switch.
It’s heavier and louder.
