View attachment 1165 You can see the slot is at the correct angle to the carpet.
The stainless steel slot glide is longer wearing, and still has the rounded bottom of a glide

The cleaning test between the 14" CMP and 14" Bentley was done on dirty carpet with a #4 TM.
The Bentley was visually cleaner with only 1 pass for each wand.

P.S. The newest manifolds from Mytee have a Stainless Tube clamped to the wand . . .
with brass fittings used to position the jets higher.
