So Marty, you have one of these with the angled cut Delrin
glide?
Not sure what you mean by too narrow, maybe you like those 4 inch mini wands. I can't see how that jet on those which is inches away from the wall/carpet join is going to dig and blast anything like these tools do.
As cheap as they are, $113 and $160 retail, you can't afford to not have at least one of them.
You know damn well you've talked you way out of (attempted) cleaning at least a 100 miles of filtration soiling by now in your career.
This is so damn easy that we don't even charge for it, and on repeats we don't even mention that we finally got their black lines out after 10 or more visits.
