Bit of a dullard question but what's the best floor mop out there? I have a pale tiled floor & whatever I use it look mucky again an hour later. I use a vileda mop but it isn't great. What about those flat one with disposable covers? How do you get into corners? You see professional cleaners with those in hotels & offices & the like. Should I just get a steam mop & use that all the time? I did have a vax one but it broke & I never replaced it. They are good but take an age to use. Maybe that's just because I'm a filthy mare. Thank you.
