Pros & cons

Dyson V12 Detect Slim

  • 5.2 lbs makes daily and above-floor cleaning genuinely easy
  • Laser dust illumination and piezo particle counter carried over from the V15
  • Power button instead of a hold-down trigger
  • Click-in battery is removable and replaceable
  • Long-term owners report the light weight keeps it in daily use where heavier sticks sat idle
  • Whole-machine HEPA filtration at a lower price than the flagships
  • 150AW is well below the V15/Gen5 — weaker on thick carpet
  • 0.35L bin is small; expect multiple empties per whole-house clean
  • Owners report battery capacity declines noticeably after ~3 years of heavy use
  • Head is narrower than the flagships, so big rooms take longer
  • No app or smart connectivity

Miele Triflex HX2

  • Build quality owners describe as a class above plastic rivals
  • 3-in-1 design: balanced top-motor stick, low-reach mode, or handheld
  • Self-standing in bottom-motor mode — park it anywhere mid-clean
  • Extra-wide Multi Floor XXL head with automatic floor-type adjustment
  • Removable, swappable battery with up to 60 minutes of runtime
  • Lifetime HEPA filter — no recurring filter purchases
  • 8 lbs — heaviest premium stick, and top-heavy in stick mode
  • 4-hour charge time is among the slowest in the class
  • No published suction figure to compare against rivals
  • Mixed owner reports on heavy debris like cat litter
  • No dock, laser, screen, or app — spartan on features for the price
