Jon Don still has strong dry units listed on their website.
CRB industry has had the same brushes as Whittaker & Carpet cleaner America since last fall.
CRB industries have improved greatly and are very similar today. The early ones were crap but today's machine is pretty decent. Buddy of mine has a bunch of both and they all blow gears.
The Whittaker Trio still blows them all away but is way over priced. Rumor has it that their latest 12" trio will soon sport a spray system.
Not exactly fair or objective review of a product when only one manufacturer is present. If you open up a
CRB industries machine of recent manufacture , you will find them very similar.
All that being what it is, BUY THE Whittaker TRIO.
