Pros & cons

Dyson V15s Detect Submarine

  • One machine handles both wet mopping and dry vacuuming without switching appliances
  • Separate clean/dirty water tanks keep you from mopping with dirty water
  • Laser dust detection shows exactly where debris is on hard floors
  • Swaps back to a standard fluffy or Motorbar head for carpets and stairs
  • 60-minute max runtime is competitive for a wet-roller stick
  • Wet roller head requires a self-clean/dry cycle after every use
  • Dry dustbin capacity (0.76L) is on the small side for whole-home cleaning
  • Significantly more expensive than dedicated hard-floor washers
  • Heavier to maneuver than a standard V15 with the wet head attached
  • Replacement rollers and filters add to long-term cost

Tineco Floor One S9 Artist Steam

  • 320°F steam system tackles dried-on grease and stains regular mopping mode won't touch
  • 22 kPa is among the higher published suction figures in Tineco's own lineup
  • 180° lay-flat design compresses to about 5 inches for under-furniture access
  • FlashDry dock hot-washes and dries the roller automatically after each use
  • DualBlock scrapers are built specifically to stop hair from wrapping the roller
  • 2-year warranty on a flagship-priced machine
  • $949 street price is expensive for a single-floor-type cleaner
  • Steam mode needs a 45-60 second warm-up before each pass
  • Hard floors only — no carpet or rug capability
  • Manufacturer doesn't publish a noise rating or full weight/dimensions
  • Dirty water tank still needs rinsing after every session to avoid odor
