Small sample: 750 ratings. This is the 'V12 Detect Slim+' Amazon listing (the one Good Housekeeping links to); other V12 listings are split.

Good Housekeeping's best for hardwood floors and Wirecutter's former top pick: ultra-light, with a dust-revealing laser and many tools. But the bin is small, the brush isn't anti-tangle, it's loud on boost, it comes with only one battery, and owners report short runtimes and early faults.

Top complaints

  • Short runtime, single battery

    A low-star Walmart owner says it runs 30 minutes at most in eco/auto and about 15 on max. Amazon's summary says some owners report the battery dying in ten minutes. Good Housekeeping got just over 50 minutes in Eco and wished it included a second battery.

  • Small bin, no anti-tangle head

    Wirecutter says its bin is 30% smaller than the V10 Konical's and it lacks the newer anti-tangle brush head. Vacuum Wars lists a 440 ml bin.

  • Early faults and reliability doubts

    Low-star Walmart owners describe problems within the first few months, a sticky wand-to-brush connection, and units that arrived looking used or damaged. Amazon's summary says reliability is mixed, including a motor that failed after three years.

What owners love

Good for
  • Mostly hard floors (laser and soft roller)
  • Light weight for stairs and long sessions
  • Lots of attachments

What experts say

  • Good Housekeeping: Best for hardwood floors (updated 2026-06-18): aced bare-floor, pet-hair and edge tests and ran just over 50 minutes on Eco. Con: no second battery.
  • Wirecutter (NYT): Former top pick, still 'a great vacuum', but the V10 Konical costs markedly less and performs similarly. The V12 has a 30% smaller bin and no anti-tangle head.
  • Vacuum Wars: #5 of its cordless top 10 (updated 2026-10-07): lightweight but powerful. It lists 85 dB, a 440 ml bin and a 60-minute battery.
