Best brush for commercial windows

What brush size/type/jets is everyone using for the bulk of their commercial work?

There are a lot of options. The new Tucker brush has been really great this season. Take a look - https://shopwindowcleaner.com/water-fed-poles-systems/brushes.html

If the glass is often cleaned and it doesn’t require an extremely deep scrub down, Unger makes a 24" rectangle brush that can except something like 12 jets which will make rinsing a breeze. This brush has great coverage but not a ton of bristles, best for maintenance cleans.
