Yes, we have two.
love them for really trashed carpet. Slower than a 175week scrub and since but much more effective, although a bit slower.
some people have streaking issues, most don't judging from my questioning of owners.
I am currently testing a prototype head that has 25% more suck and squirt, not sure if it will eliminate the streaking Im seeing on certain thicker carpet types but it should speed things up.
I have not used a HOSE yet so no comment.
