The Shark IONFlex DuoClean Cordless vacuum. The Shark DUO CLEAN Technology has an integrated dual brushroll system (soft brushroll and bristle brush) for better cleaning on hard floors or carpeting. DuoClean Triple Particle Cleaning tackles 3 types of floors messes; large (without snowplowing), small and stuck-on particles, from both carpets and floors.

Smart-Review Commentary: The Shark IONFlex IF251 DuoClean 2x combines a powerful ultra lightweight upright vacuum with a detachable handheld vacuum. This is Shark’s best cordless vacuum. Swivel steering makes it easier to maneuver than traditional fixed wheel vacuums. Shark has a DUO Clean brushroll system to help clean both hard floors and carpets. The TRIPLE PARTICLE CLEANING allows the Shark IonFlex to vacuum large, small and stuck on particles. The included pet multi-tool attaches to the handheld vacuum and will get ground in dirt, pet hair, and dust off your upholstery, stairs, and car interiors. With two batteries included, you can charge one battery while using the other. Easy to reach power & brushroll controls. Each battery gets about 25 minutes of runtime. Unlike many cordless vacuums, this one has LED headlights to see under furniture or dark places. Shark also includes other tools to help in cleaning. This model has received excellent reviews by consumers. This model is a Smart-Review top pick for cordless vacuums.
