Ranked #2 in Best Cordless Stick Vacuums

Dyson V15 Detect

4.2

3 sources$849.99as of Oct 16

Dyson's flagship cordless, the V15 Detect, is the consensus pick from RTINGS, Vacuum Wars and TechGearLab in 2026. A 240-AW Hyperdymium motor, laser dust-reveal head, piezo particle sensor and 60-minute swappable battery let it clean nearly any home in one session. You pay flagship pricing. No other vacuum in this group matches its raw suction, sensor intelligence or hard-floor visibility.

Strengths

— Piezo particle sensor counts and sizes debris and auto-boosts power when load increases
— 60-minute swappable battery delivers a true 59-61 minutes in Eco mode per RTINGS and Vacuum Wars
— Fully sealed HEPA filtration captures particles down to 0.1 microns

Watch-outs

— Trigger-based switch fatigues the hand on long sessions per several reviewers

Ranked #1 in Best Cordless Stick Vacuums

Shark Stratos Cordless Vacuum

4.2

3 sources$470as of Oct 17

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.

Strengths

— 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
— Long runtime: CNET measured 80 minutes on medium suction

Watch-outs

— 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
— Odour-neutraliser cartridges smell artificial and need replacing every six months

How they stack up

Dyson V15 Detect

Replaces Dyson V8 as the do-it-all pick for buyers who want maximum cleaning capability.

Shark Stratos Cordless Vacuum

CNET's figures put the Stratos at 9 pounds and 80 minutes of tested runtime, against 6.8 pounds and 60 minutes for the Dyson V15 Detect, which also offers a dust-revealing laser head the Stratos lacks. Unlike the Shark Cordless Detect Pro IW3511, the Stratos has no self-emptying base, so the bin is emptied by hand.
