The Shark Stratos (IZ862H) is a cordless stick vacuum with a two-roller DuoClean head, automatic Clean Sense IQ suction, a HEPA filter and a removable battery, weighing about 8.9 pounds. CNET named it its best overall cordless vacuum after it picked up 95% of sand on average across hardwood and carpet, Vacuum Wars recorded the first perfect 100 in its carpet deep-clean test, and TechGearLab found it a standout on hardwood. Reviewers agree it is heavy, Homes & Gardens and TechGearLab disliked the scent cartridge, and TechGearLab found it weaker on thick rugs. It suits mixed-floor homes, especially those with mostly hard floors; people who want a light handheld or a self-emptying dock should look elsewhere.
- — First cordless to score a perfect 100 in Vacuum Wars' embedded-sand carpet test
- — Standout hard-floor cleaner, picking up 97% of debris on hardwood in TechGearLab's test
- — Heavy at about 8.9 lb, tiring in handheld mode and when reaching overhead
- — Less effective on thick, high-pile rugs, which need extra passes
