This is all true but dull, but I guess this is proper forum for such.
I've got one from Lakeland for about sixty pounds, and I mostly think it's good. I found it weird at first. You have to invert your technique from normal mops, so, you go really slowly and gently on grotty parts (to steam off the grot) and then sweep quickly back and forth over cleaner parts.
I mop the walk-through part of the floor more often (most days now) as somehow it's less mental effort than a bucket. The no-detergent thing is good, as is the sterilisation factor. I change the head after doing the whole house, or when it gets grotty from doing bits. Mine came with 3 cloths and I wash them three or four times a month. The only real pain is that you have to wash the cloths at 30 degrees and I don't have anything else that I wash at that temp, but I might just start putting them in the hot wash with the dishcloths anyway.
Mine folds up quite small and it works fine to do cupboard fronts, bathroom walls, cooker hood, etc, as well as the floors.
Oh, and it dries streakily on high gloss but I don't have anything high gloss so I only know this because it's a Big Divider with steam mops.
You may as well get one from Lakeland and try it, because (my rationale) if it turns out to be marmite, you can just send it back.
