Vacuum Wars calls it the best cordless Shark has made: the first cordless to score 100 in its carpet deep-clean test, with an anti-hair-wrap brush and a 5-year warranty. But the handle is heavy and awkward as a handheld, max-power runtime was about 10.5 minutes, and Amazon owners are split on battery life and on whether it keeps working properly.

Common Shark Stratos IZ862H problems

  • Mixed battery and reliability reports

    Amazon's review summary says battery life, functionality, cleaning, suction and value for money all get mixed reviews: some owners report good battery life while others find it terrible, and some say it stops working properly. Vacuum Wars measured 10.5 minutes on max against a 60-minute Eco rating and estimates 20-30 minutes in auto mode.

  • Heavy, awkward handheld

    Vacuum Wars says the handle (1,640 g; 8.9 lb in its spec table) is heavier than it would like and awkward as a handheld. Amazon owners are split between relatively light and a bit heavy.

  • Missing extras for the price

    Vacuum Wars notes there is no powered upholstery tool and no auto-empty dock, and calls it the most expensive Shark cordless stick. It lists 80 dB, above the 77 dB cordless average it cites.

What owners like

  • Perfect carpet deep clean

    Vacuum Wars says it was the first cordless to score 100 in its carpet deep-clean test (the average of 58 cordless vacs was 91) and that surface pickup is about as good as it gets. It ranks #3 of the cordless top 10.

  • Anti-wrap brush and auto power

    Vacuum Wars found the HairPro brushroll handled pet and human hair well, and the Clean Sense IQ mode adjusts suction to the dirt it detects. The bending MultiFLEX wand helps under furniture.

Highly ranked cordless vacuums whose biggest complaint is a different kind of problem.

#7 in cordless vacuumsBissell PowerClean DualBrush 280W Self-Standing Cordless Vacuum

Wirecutter's best self-standing stick vac and #6 in Vacuum Wars' ranking, excellent on pet hair, with a 5-year warranty. But it's heavy and top-heavy, misses edges, is loud (84 dB), has a tiny bin, and runs only about 13 minutes on max.

Its catch: heavy and top-heavy#8 in cordless vacuumsTineco GO Pet Cordless Stick Vacuum

Wirecutter's budget pick, with top-tier suction and the biggest bin among its picks. But it seizes up on medium and thick carpet, falls well short of its claimed 60-minute runtime, has a finicky bin, and replacement batteries are hard to get.

Its catch: seizes on thicker carpet#9 in cordless vacuumsShark PowerDetect Cordless Stick Vacuum

The strongest cleaner in Wirecutter's tests and Tom's Guide's best stick pick, with a 5-year warranty. But it's the loudest and among the heaviest, top-heavy to push, and has a high low-star share on Amazon, where owners report weak suction and short battery life.

Its catch: heavy, top-heavy and hard to push
