Verdict

The H.Koenig NV680 is a portable handheld steam cleaner featuring a 1200W motor, a 3.5 bar steam pressure rating, and a continuous steam flow of 40 g/min that reaches temperatures up to 102°C to eliminate 99.99% of bacteria without chemicals. Its primary advantages include a fast 3-to-5-minute heat-up time, an eco-friendly multi-surface cleaning capability across tiles, textiles, and glass, and high versatility provided by its lightweight 1.3 kg frame, 3-meter power cable, and 13 included accessories like extension tubes and nylon brushes. However, its main disadvantages are a relatively limited 400 mL water tank capacity that reduces continuous runtime and requires frequent refills during larger tasks, alongside initial water sputtering if overfilled.
