I have all three
glides
The slot glide get's used 99% of the time.
Hole glide about 1% on a few com jobs we do
Hole glide doesn't clean as deep on cut piles.
Dry times are insignificant compared slot if pre-spray is used in sufficient quantity .
Most jamokes have never done same room, same day side by side tests with identical wands equipped with different glides to support their drying claims.
Cause if they did, they'd know that in 30-45 minutes after cleaning, you won't be able to tell any difference and there won't be a dimes worth of difference in "complete" dry times .
Hole glide is by far easiest to push.
But again, it doesn't clean deep enough for "my" likes on cut piles
..L.T.A.
