Verdict

The COSTWAY 1.8L Steam Cleaner is a 2000W multipurpose household appliance designed to provide heavy-duty, chemical-free deep cleaning with a powerful steam pressure of up to 5 bar and a maximum operating temperature of 160°C. Main characteristics include a 1.8-litre water tank that provides up to 30 to 35 minutes of continuous steam, a preheating time of 8 to 10 minutes, and a comprehensive 13-to-15-piece accessory kit for versatile surface cleaning, including floors, windows, and carpets. Key pros are its strong stain-removal performance, smooth mobility via rolling wheels, extensive reach enabled by a 5-metre power cord and a 1.5-metre hose, and multiple safety integrations like a trigger lock, safety valve, and precise pressure gauge. On the downside, the primary cons are its notably long preheating time compared to handheld models, a cord that may lack an automatic rewind feature, and the requirement to let the unit completely cool down before safely unscrewing the cap for water refills.
