ok, I have 24 inch tiles that have the rough/uneven finish and dirt gets trapped in the lower dips and pits, will this get in those hard to reach places??? I have wanted something that will help get these floors clean once and for all... I don't want to have to call a profesh every three months to do it!
Also... does it work on grout? (sp?) Mine is lighter... In some places

lol Not so much anymoye.. this desert dust is awful!
If it tackles those two areas well and is easy to use... I'm sold!
Oh, and do you have to go painstakingly slow?? ot can you do your floors in a reasonable amount of time?
