Higher ratedRanked #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

Ranked #3 in Best Cordless Stick Vacuums

Tineco Pure ONE S15 Pro

3.8

2 sources$700as of Oct 10

Tineco's most direct answer to the Dyson V15 Detect is the Pure ONE S15 Pro: similar sensor-driven auto-suction, a tangle-fighting brushroll and a polished LCD interface for less money. What it gives up is the V15's raw suction headroom and Click-in battery swapping; what it gains is a quieter, smarter-feeling experience. Buyers who like the V15 concept but balk at the $749 price will find the S15 Pro the closest premium alternative on the market.

Strengths

— ZeroTangle V-shaped brush actively repels hair, eliminating manual de-tangling
— 5-stage filtration captures 99.9% of allergens per Tineco testing
— Contactless dustbin empties without touching debris

Watch-outs

— Battery life of 40 minutes (auto mode) trails Dyson V15's 60 minutes
— S15 Pro model is sold direct from Tineco, not on US Amazon

How they stack up

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.

Tineco Pure ONE S15 Pro

Closest direct alternative to the Dyson V15 Detect with similar smart-sensing at $150 less. Better hardwood polish than the Shark Cordless Detect Pro. Heavier than the Dyson V8 but offers far stronger suction and a 2-in-1 wet-dry capability the V8 lacks.
