Verdict

The Black+Decker FSMH1321-GB is a versatile 1300W 7-in-1 steam mop featuring a 500ml water tank, a 6-metre power cable, and AutoSelect technology to automatically regulate steam based on floor type. Main pros include a rapid 15-second heat-up time providing up to 20 minutes of continuous runtime, chemical-free sanitisation that kills 99.9% of bacteria, and a detachable handheld unit with multiple cleaning accessories. However, notable cons include a relatively short cable length and potential water leakage from the filler cap.

What customers dislike about Black+Decker FSMH1321-GB?

The 6-meter electrical cord lacks a convenient built-in storage wrap system.
Can leave a noticeable amount of excess moisture and wet streaks on certain floor types like tiles.
The specific accessory kit variant can be confusing as certain parts like the cleaning glove are sometimes sold separately.

The water reservoir has an unusual opening shape that makes it prone to spills unless filled very carefully or with a funnel.

Summary of the review

Black & Decker FSMH1321 7IN1 steam-mop Review

The Trusted Reviews assessment of the Black & Decker FSMH1321 7IN1 steam-mop praises the budget-friendly, 1300W unit for its great general steam cleaning power, rapid 15-second heat-up time, and versatile accessories. While the 1.6kg detachable handheld unit is highly effective, the review notes cons including a leaky water filler cap, a short power cable, a rigid handle, and a somewhat flimsy-feeling upright frame.
