I'm speaking of the triangulated vacuum chamber.
IF the tube joins in a linear fashion, there is no better design.
When I first tested the SharpShooter to see how my
Glide functioned, I fully expected to use it for half a room and go back to my S bends.
Nope, instead I marveld at my 5 ft reach with no leaning required, vacuum was excellent and because there wasn't really any furniture to get under I ended up completeing the whole house with it.
The tear drop may or may not increase the speed of airflow but it certainly reduces the chatter of the Evo's, and unline the Evo's this wand cleans right to the edge with out modification.
Evo Glides sell incredibly well, I have to pack up a Hard Surface Glide for a owner in a few minutes actually. New and old cleaners alike love these straight tubed wands for what ever reasons.
USP is workining on a new model that wont have the scews to mount the Glide (which will be OEM) but rather a familiur mountin system that will alow for very quick change outs to other style Glides.
There is another large wand seller looking at offering the same thing, a wand with....options....
