if the 175 is like running a buffer on a hard floor ive had plenty of experience with that I was in the military for 5 years and had pleany of floors to polish and strip of wax..
if you have experience "stripping" floor finish off tile (not to be confused with hi-speed polishing)
then you can handle a rotary, cause it's the same 175 RPM rotary scrubber you used to strip wax.....er..floor "finish" (or one of the VCT gEEks will yell at us for calling it "wax")..

.
The difference will be the friction, or "grab" on carpet compared to wet tile..
there's much more when the rotary in on carpet.
You balance and move left to right just the same as on tile...just lots more "grab"
but every bit as easy to run and maneuver .
Just start in an open area.
a 15" rotary is fine...especially for smaller/tighter areas
a rotary is far
superior to a cylinder brush machine as far as shearing soil off the fiber.
a rotary is also a much more versatile tool.
you can use a shampoo brush, bonnets or VCT pads to scrub carpet with .
each one can be a more aggressive scrub than the next, as carpet type and soil conditions dictate .
Be advised, keep the carpet heavy lubed with slippery detergent (pre-spray) or you can burn/ruin a carpet with aggressive brushes or VCT pads
