Shark Stratos Cordless Vacuum vs Shark Vertex Pro Cordless Vacuum

Both are Shark cordless sticks with DuoClean PowerFins and a self-cleaning brushroll, so the real split is weight and dirt sensing versus raw suction headroom. The Stratos (IZ862H) adds Clean Sense IQ, an odor neutralizer and a folding MultiFLEX wand, but it weighs about 12.4 lb and owners call it heavy at the top with so-so battery life. The Vertex Pro (IZ662H) is the lighter pick at about 8.8 lb with a higher-voltage motor and a bendable handle, but it gives up the dirt sensor and odor control. Buy the Stratos for carpet-heavy homes with pets and allergies; buy the Vertex Pro if you want easier carrying and stair work.

• Choose the Shark Stratos if you want automatic dirt sensing, odor control and a wand that folds for storage, and you mostly vacuum carpet.
• Choose the Shark Vertex Pro if lighter weight and stronger suction headroom matter more to you than a dirt sensor.
