Cleaning mechanics
The powered lift-away function cleans above the floors without tiring your hand. Most of the weight is located on the bottom so even if the PowerDetect is heavier, you won't notice it.
The Shark's famous Duo roller system makes vacuuming much more efficient since one roller is made for picking up things (even large debris), and the second one is designed for deep carpet cleaning.
The DuoClean PowerFins HairPro is a previous generation designed to resist hair tangles, while the DuoClean Detect is equipped with sensors that react to cleaning tasks.
The accessory kit is different, both vacuums come with four items.
Smart features
Both upright have lots of power for deep carpet cleaning.
Same power, more intelligence
The Shark PowerDetect adjusts suction on carpets, along the walls and edges, or when detecting dirty areas. With the Shark Stratos, you have to switch the mode manually.
DIRECTION DETECT: Shark’s direction Intelli-Sense sensor recognizes which direction you are vacuuming, and automatically directs powerful suction to whatever direction is needed, for maximum cleaning in both forward and reverse.
Stratos
The Shark Stratos is one of the most powerful uprights in the lineup made for deep carpet cleaning and picking up all kinds of debris.
A classic powerful vacuum for big homes with lots of carpets that can handle debris and has zero-tangle technology.
A powerful machine ideal for homes with carpets and pet owners
Shark POWERDETECT AZ4002
Editor's choice
The AZ4002 is the smartest with all the sensors that adapt suction to floor type and dirty areas.
Which one to get?
With the latest brushroll system, smart detection, and lots of power, the latest Shark POWERDETECT AZ4002 is a great buy in 2025.
However, the Shark AZ3002 Stratos Upright has the same power and a lower price tag so if you don't mind the lack of smart sensors, the Stratos is still a valid upright that doesn't have competitors for its price.
