Let’s clear up the confusion: H12 vs H14 vs H15 (wet–dry vacs)

H12 Pro

• The reliable baseline. 35-min runtime, 900 ml clean tank, hot-air self-dry, edge-to-edge brush. Good for routine messes and smaller runs.

H14

• Step up in power and usability. 18 kPa suction, 35-min runtime, 880/650 ml tanks, 180° lie-flat, 5-min fast hot-air dry. Great if you want newer handling without going full flagship.

H14 Pro

• Refined H14. Still 18 kPa, but adds smarter traction, LED headlight, app control, 60°C hot-water brush wash, and stretches runtime to about 40 min. Better for bigger spaces and frequent use.

H15 Pro Heat

• Flagship. 22,000 Pa suction, larger 5,000 mAh battery pack, up to 72-min runtime (Quiet), hot-water modes, triple-edge cleaning, 180° lie-flat. Heavier, but strongest cleaning and longest runs.

Which to pick

• Choose H12 Pro if you want the value play and mostly light daily spills.
• Choose H14/H14 Pro if you want better handling, lie-flat reach, and faster self-care; Pro if you need the 40-min stamina and hot-water brush wash.
• Choose H15 Pro Heat if runtime and raw suction matter most or you’re covering larger square footage in one pass.

BONUS: If you tell me your floor types, home size, and how often you’ll run it, I can point you to the best fit from these three.
