Just read this interesting article on an independent suppliers page, so not bias towards Cimex ,
It does show , how accurate the figures are , I'm not sure , but imo it does show that you guys using standard rotary's for encap cleaning are either not encapping to the full potential or your spending much more time than necessary during the cleaning process .
Here is the article .
CimexScrubbing Equipment: Any scrubber with strong agitation can be used for encapsulation cleaning. The "muscle" of this cleaning method is AGITATION. That's why we recommend Cimex and Orbot scrubbers for encapsulation over a standard 175-rpm scrubber (ie – Polivac, Truvox, Taski etc). They Orbot and Cimex machines safely produce the highest degree of agitation of any scrubbers on the market. Their effectiveness is unmatched. The Cimex has 3 planetary counter-rotating brushes. The 3 brushes spin clockwise while the drive deck turns counter-Orbotclockwise. So it’s actually turning in both directions simultaneously (kind of like the teacup ride at the fair). Therefore it actually scrubs all sides of the fiber with each pass. To put this into context, the Cimex is over 6 times more efficient than a standard rotary machine. Three brushes spinning at 400 rpm as compared to one brush turning at 175 rpm means there's a 600% increase in cleaning aggression. In other words, if we were to clean a very dirty carpet with 3 passes using the Cimex it would require 18 passes with a standard rotary machine to accomplish the same thing. And since the planetary cleaning heads are counter-rotating, there's no tip bloom or damage to the carpet. The Cimex machine can clean between 185-300 square metres per hour.
