Well after using the vita-mix, there really isnt anything to strain.
I usually use it to LIQUIFY whole raw fruit and veggies like carrots,
beets, apples, oranges, and pineapple. Throw them in whole, hit the
switch & crank up to full speed & by the time I'm done whipping it,
the drink is thick, but zero chunks of produce exist. I'm just a big
fan of getting the roughage as well as the juice from my produce.

This is by far the ballsiest blender I've ever seen. A little pricey
(around $400), but totally worth it. It has a 2 horsepower motor &
at top speed spins at over 220 MPH! I promise you the whole
wheatgrass (maybe also throw in a cup of filtered water) will be
reduced to a thick dark green drink. I'm not very concerned about
flavor, as much as I am getting the roughage and 100% of the WG
juice.

For health-conscious people, this thing makes a raw-produce diet much
easier & tastier.
