Help which one Cimex, Trio, Host, Rotowash?

[Nickms]

Hi, I run a single operator cleaning business. For a while now I have been cleaning metre sq carpet tiles for a company who specialise in event hire. Until recently I have either been vacuuming the tiles or when they become too soiled I pressure wash them. Often grass seed and straw gets walked in and the only way to get this out is to use the pressure washer. They have recently purchased another 2k tiles and are expanding rapidly. Pressure cleaning them takes far to long to both clean and dry and is too labour intensive and straight vacuuming is not good enough. I started looking at Host machines, but they seem slow and the chemical is exorbitant, I have come across the cimex, but two things concern me the drying time and will I be able to vac out any grass/straw? The whittaker trio seems to be a good option. I should add that I will need to import into Australia and use a stepdown transformer, also if I am going to purchase a machine I may as well get one that will do residential as I have a large client base to build upon.

I should add that the tiles will be laid out 400 sq metres at time and not stuck down. I have run a host machine over one and it did not pick up the edges.

Your advice is greatly appreciated
