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.

Top complaints

  • Heavy, top-heavy and hard to push

    Wirecutter says it weighs 8 pounds, 2 more than the Dyson V10 Konical, is less maneuverable and can feel heavy on longer sessions. Tom's Guide calls the Clean & Empty version top-heavy. Amazon's summary says several owners find it doesn't glide easily, and a low-star Walmart review calls it too heavy and awkward to handle.

  • Loud

    At full power Wirecutter measured 85 dB, the loudest vacuum it tested, and says the noise is annoying. Vacuum Wars lists the Clean & Empty version at 82 dB, and Tom's Guide says auto-emptying is loud.

  • Mixed suction and battery reports, suction loss

    Amazon's summary says some owners find it doesn't pick up debris well, and others say the battery doesn't last and suction is weak. Low-star Walmart owners say it lost suction after three months and clogs easily. Wirecutter adds that longer hair can tangle in its dual rolls, and Tom's Guide says the sensors need extra cleaning.

What owners love

  • Best pickup tested

    Wirecutter says it was the only vacuum to get all 2 ounces of coffee grounds out of its test carpet, and its recessed head handles cereal without snowplowing. Vacuum Wars says the Clean & Empty version earned perfect carpet deep-clean and hard-floor scores.

  • Bending wand and auto power

    Wirecutter and Tom's Guide both praise the hinged wand for reaching under furniture without bending over, and the Detect mode that ramps up power on dirty spots and edges.

  • Five-year warranty and optional dock

    Wirecutter notes Shark's five-year warranty and a version with a self-emptying dock for about $100 more. Tom's Guide says the dock held weeks of debris.

Good for
  • Deep cleaning carpets and rugs

What experts say

  • Wirecutter (NYT): Runner-up (updated 2026-09-30): the best pure pickup it tested and about 40 minutes in Detect mode, but 8 pounds, the loudest at 85 dB, and a 22-ounce bin.
  • Tom's Guide: Best stick vacuum (Clean & Empty version, updated 2026-08-04): excellent debris pickup and floor sensing, but top-heavy, loud when emptying, and its sensors need maintenance.
  • Vacuum Wars: The Clean & Empty version ranks #3 of its cordless top 10 (updated 2026-10-07), with perfect carpet deep-clean and hard-floor scores; it lists 82 dB and a 700 ml bin.
