Shark AZ4002W POWERDETECT Upright Vacuum

The Shark AZ4002W has a powerful motor with strong suction for cleaning carpets and hard floors. Reviewers consistently report excellent cleaning performance across different surface types.

The vacuum picks up pet hair on carpets and upholstery well. It comes with specialized tools for removing pet hair from hard-to-reach areas.

It weighs approximately 15 pounds, making it lightweight enough to maneuver easily across multiple floors and stairs.

For pet hair, look for strong suction (roughly 20,000 Pa or more on a robot vacuum, 150 AW or more on a cordless), a tangle-resistant brush roll, a dedicated pet tool, and HEPA filtration, which by definition captures 99.97% of particles at 0.3 microns. Dyson, Shark and Bissell all make well-reviewed pet models. Use the Pet Hair Specialist filter on our comparison table to see which ones are in stock and what they cost right now.

Most manufacturers suggest replacing filters every 3 to 6 months, depending on how often you vacuum and whether you have pets. HEPA filters usually last 12 to 18 months if you clean them regularly. Washable foam filters on bagless models should be rinsed every 1 to 2 weeks and dried fully before going back in. Replacements typically run $15 to $50. A clogged filter chokes airflow, so suction drops noticeably well before the filter looks dirty.
