When comparing prices, you must look beyond the surface and evaluate the wattage (typically 1200W to 2400W), as higher power ensures faster heating and more consistent steam. The soleplate material significantly impacts cost; ceramic and titanium coatings are premium options for non-stick performance, while stainless steel is a durable, mid-range choice. Additionally, check the continuous steam rate (g/min) and steam boost capacity, as these performance metrics are the primary drivers of price variance between basic and professional-grade models.
