Hi Guys - I'm completely new to this and am in the very early stages of research so apologies in advance if it sounds stupid. Here is my question. Do my rotary tools get attached directly to the TM as well or is that a stand alone unit? Same games for tile and grout cleaners... would I need a separate machine or is it just an attachment that allows me to use the carpet cleaner for tiles/grouts? I guess in the general sense what I'm trying to find out is if I wanted to do tile/grout, hardwood, rugs, etc.... do these each require stand alone units or can I just buy attachments that allow me to use my TM for the above mentioned?
