I'v had an asda's own make one £27 it broke after a few uses, it soaked the floors but it was very light to use..
I'v now got a vax make £80 it cleans with the steam as its ment to (not soak) but its very heavy so is now a job for Mr A ..
I've just got this one and its very good -got a 'Which' best buy award -dare not put a link in case its see as advertising but its called the H2O MOP® X5™ and you can buy it from Thane direct for £99 -it has attachments for floor steam dusting,windows and upholstery -its my new toy at the moment -takes grease of oven bottoms and got rid of shoe polish on ceramic tiles -highly recommended
Mine is easy to use light and manouverable with a swivel head...bought from Argos...think it was around €90 with 3 pads...can buy extra pads from Argos...
I wouldn't go for Karcher. the cloth heads dont stay on the steam bit. I replaced my karcher with an oreck which i am very pleased with. It only does floor cleaning but that's all i want.
We've got a Vax and it's OK. It fetches up the ceramic floor tiles a treat even after we've been tramping all the slush and crap we've been getting lately all over the place.
