Shark IZ840H Stratos Cordless Vacuum

The Shark IZ840H Stratos is a certified refurbished cordless stick vacuum with Clean Sense IQ technology that detects dirt levels and adjusts suction automatically to preserve battery life. The DuoClean PowerFins system pairs a soft front roller for fine dust with stiff rear fins that grab pet hair and debris from carpets in one pass. It runs up to 50 minutes per charge with consistent power throughout. At 8.9 pounds, it's heavier than ultra-lightweight models but delivers stronger suction and more durable construction. The vacuum converts to a handheld for stairs, upholstery, and car interiors. This refurbished unit works well for medium to large homes with mixed flooring and pet owners. It comes with all essential components and a 90-day warranty, with minimal wear. The trade-off is a bulkier profile than ultra-slim competitors, but you get sustained suction and dirt detection that responds to your floors in real time.
