I'll tell you what, I'm rather supprised at how well a rotary can clean compared to an OP. I haven't used it for anything real dirty yet, I assume that's were I'll see the difference in results. Hard to imagine that a rotary can clean the trashed out carpet as welll as an OP, I can't wait for that chance to try it out and see. (op will be on stand by)
I do like the ease of movement with a rotary, You can go side ways and slant ways and back words and forwards, long ways, up ways and down ways, and in ways and out ways. all with just a twitch of your pinky toe. I'm still new with it, so I may end up thinking it sucks by the end of the week, and toss it in the columbia river, but so far so good/.
