Dont know about that Tony but recently bought one to see if it would help clean grout haze etc from hard to clean non slip tiles. JML tat. Didnt work so sent it back
I was considering getting one of these to clean dirty grout. But I think I'll opt of LTP grimex and then seal the grout again afterwards. Thanks for the info advancetiling.
I get clients ask me about this and in the past I have said I wouldnt think they would work, now I have more info so if asked again I know more about it. Thanks lads.
It was one of those on offer in sunday magazines.Had 3 different heads cost about £70 i think.Said on advert it cleans ceramics and stone. Im not doubting that good money will buy a better heavy duty one but this one just wasnt up to the job.Maybe ok for general house cleaning but certainly no good for cleaning aftermath of mapei negro up with.
