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.

  • Large 1.5L water tank capacity allows for long, continuous cleaning sessions without constant refills.
  • Comes with a versatile selection of 19 accessories for various surfaces like tile grout, windows, and floors.
  • Provides strong steam pressure (up to 4 bar) that is highly effective at lifting deep grime and stains.
  • Lightweight canister design with integrated wheels makes it easy to roll and maneuver from room to room.
  • Features a trigger lock switch that provides continuous steam output without needing to hold down the button.
  • Offers chemical-free cleaning that safely disinfects surfaces using only high-temperature water.

What customers dislike about Costway 1.5L Blue?

  • Features a narrow, small water inlet opening that makes refilling the tank tricky and inconvenient.
  • Requires a noticeable pre-heating wait time of 5 to 8 minutes before steam reaches operating pressure.
  • The power cord is somewhat short, which restricts extended movement and often requires an extension cord.
  • Certain plastic attachment components and extension tubes feel fragile under heavy physical pressure.
