Verdict

The COSTWAY 1.5L Blue Multipurpose Steam Cleaner features a robust 2000W heating element that produces a 4.0 bar high-pressure chemical-free steam reaching up to 108°C (226°F) for deep sanitation. Its 1.5-litre water tank preheats in approximately 5 to 6 minutes, delivering up to 45 minutes of continuous steam controlled via an adjustable steam trigger. The unit is highly versatile, coming equipped with a child safety lock, an automatic overheat shut-off system, smooth-rolling wheels, a 16ft power cord, and up to 20 functional accessories for cleaning floors, windows, and upholstery. Main pros include its chemical-free disinfection, excellent high-pressure performance on hard surfaces, and extended runtime per tank. However, cons include a lower cleaning effectiveness on delicate fabrics or carpets, and some user reports regarding the lack of durability in the hose construction and accessory attachments.

Summary of the review

Costway boiler steam cleaner EP24434US review

The Costway Boiler Steam Cleaner (EP24434US) is a 2000W, 1.5-litre machine offering 45 minutes of continuous, 4.0-bar pressure steam with 19 versatile accessories for effective household cleaning. While praised for its quick 5-6 minute heat-up time and excellent sanitizing power, the unit is hindered by a short 10-foot power cord, slightly flexible extension tubes, and a lack of on-board storage for all attachments.
