What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
POWERDETECT Upright was checked against manufacturer identity, exact current U.S. price, manual and support, independent exact-model evidence and bounded owner evidence.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner evidence is retained as a floorhead, collection, reach, maintenance, parts and service checklist for POWERDETECT Upright, not a cleaning, exposure, failure or repair rate.
Reports are self-selected and span different floors, carpet piles, debris, pets, cleaning frequency, maintenance, dust sensitivity, homes and service regions. They cannot prove cleaning, allergen, noise, ergonomic, surface-protection, reliability, durability or repair outcomes.Self-selected exact-model discussions surface floorhead fit, carpet push effort, hair wrap, bag or bin exposure, filter care, hose and cord reach, stairs, storage, parts and service. Homes, floors, debris, pets, maintenance and service regions differ, so these reports do not establish cleaning, allergen, noise, ergonomic, failure or repair rates.

Shark identifies AZ4002 as a bagless Powered Lift-Away upright with dual brushrolls, four automatic detect functions, reverse pickup, HEPA filtration and odor cartridge. The corded bagless upright uses DuoClean Detect dual rollers, a self-cleaning main brushroll and Powered Lift-Away so the powered floorhead can remain active with the pod detached. Sensors adjust behavior for detected dirt, floor, edge and travel direction; they do not identify every debris or surface risk

The corded bagless upright uses DuoClean Detect dual rollers, a self-cleaning main brushroll and Powered Lift-Away so the powered floorhead can remain active with the pod detached. Sensors adjust behavior for detected dirt, floor, edge and travel direction; they do not identify every debris or surface risk Dry-use, cord, brushroll, filter, obstruction and maintenance instructions remain controlling.
Shark publishes a five-year limited warranty, exact quick-start material, support and selected replacement parts. Sensor cleaning, roller access, filters and odor consumables add maintenance, while warranty does not prove repairability or uptime A 1.9-liter-class bottom-empty bin, foam and post-motor filtration require recurring cleaning. HEPA and manufacturer particle claims use specified tests; emptying can expose the user to captured dust and an odor cartridge intentionally adds fragrance
TechGearLab tested exact AZ4002 carpet, hard-floor, pet-hair, filtration and usability behavior, including lower high-pile and pet-hair scores than some marketing might imply. Test debris, timed passes and flooring do not guarantee household cleaning Independent findings remain bounded to the exact tested unit, surface, debris, method and date.

EPA explains that indoor air quality depends on pollutant sources, ventilation and multiple control strategies. A vacuum filter or pickup test alone cannot establish room exposure or a health outcome.
CPSC maintains current recall records. Check the exact model and serial before use and follow any stop-use or remedy instruction; an absence from a current search is not a future safety guarantee.
