Bottom Line
The Shark POWERDETECT AZ4002 is a powerhouse vacuum especially suited for pet owners and anyone looking for tough, thorough cleaning on carpets and hard floors. Its standout suction strength, Lift-Away versatility, and helpful features like the white light and odor cartridge make it a top contender in its class. However, be prepared for a heavier machine and minor quirks like limited hose length and fiddly dust cup engagement.

Overall, if heavy-duty suction and pet hair pickup are your priorities, this vacuum is worth serious consideration.
