Shark IZ840H Stratos Cordless Vacuum

Meet the Shark IZ840H Stratos Cordless Vacuum—a certified refurbished powerhouse that delivers Clean Sense IQ technology for smarter, more efficient cleaning. This stick vacuum automatically detects dirt levels and adjusts suction accordingly, ensuring thorough pickup without wasting battery power. The signature DuoClean PowerFins system combines a soft front roller for fine dust with stiff rear fins that dig deep into carpets, capturing everything from pet hair to cereal crumbs in a single pass. The Stratos runs for up to 50 minutes on a single charge with consistent, fade-free power throughout the entire session—no gradual weakening as the battery drains. At 8.9 pounds, it's slightly heavier than ultra-lightweight models but still manageable for most users, and that extra weight often translates to more robust construction and stronger suction. The vacuum converts to a handheld for above-floor cleaning, tackling stairs, upholstery, and car interiors with ease. This refurbished model suits medium to large homes with mixed flooring, pet owners dealing with embedded fur, and households that prefer longer cleaning sessions over frequent recharging. As a certified refurbished unit, it shows minimal wear and includes all essential components with a 90-day warranty. The main trade-off is the slightly bulkier profile compared to ultra-slim competitors, but the payoff comes in sustained suction power and intelligent dirt detection that adapts to your floors in real-time.
