Hi
Welcome to the forum
You will find two main flavours of advice will be served by forum members and it's up to your pallete to select the one you prefer. In essence, both have been posted allready with gerry suggesting the detergent route and rambly opting for the splitter.
I have used both on tiles and prefer detergents, but its up to you to decide.
I think the key to cleaning tiles is good agitation. We use a shampoo brush on a heavy rotary as an alternative to more lightweight solutions like a host or sebo duo.
Alas, whatever you use, put out a good quality prespray and agitate it to death. We have been using traffic clean from prochem, or something a bit milder (crystal green or fibresafe gold) if the fibre doesnt like the solvent or alkalinity of TC. We then rinse it with acidic rinse (fibre and fabric rinse or alltech conc acid rinse). Others might not like our choice, but it does a good job.
In one extremely soilded and almost flat carpet, we went over it with bonnet (think we used splitter and charly pads) as it seemed to be wicking a bit.
Hope this helps
Graeme
