Deep cleaning carpets in today’s busy world can be quite a challenge. The time-consuming process requires a lot from staff who are often stretched too thin. The design of traditional extractors often makes extraction tiresome and labor intensive. In addition, in crowded buildings, closing off a portion of the floor for a few hours can be a hassle. As a result, facilities are often extracting less, to the detriment of the life and appearance of the carpet.

The University of Utah was looking for a solution to address these needs when Windsor Kärcher Group approached them with an opportunity to perform some design validation tests on their latest extractor, the Armada BRC 40/22 C. Todd Stoneking, the supervisor of custodial services, took advantage of the opportunity and took detailed notes on this machine compared to their current method.

The Armada, the new extractor and interim cleaner that they used, features a steerable, rotating extractor deck. This deck allows the machine to extract in a forward motion, unlike traditional extractors that need to be pulled backwards to operate. This also means that it is easier to maneuver and more ergonomic for the operator. The steerable head allows for cleaning in any direction, even in reverse, for optimum mobility.

The University’s results were impressive. Over a two-month trial period, they managed to cut the time spent cleaning by over 50 percent. In addition, the carpets’ appearance dramatically improved, enough that the difference could be seen by the naked eye.

Currently, 30 percent of the cleaning activity with a self-contained extractor is wasted motion by having to walk forward with the machine tilted back to begin the next cleaning pass. The Armada addresses this wasted time with it’s unique walk-forward and steerable motion. In addition to more productivity, workers noticed that the carpets dry quicker with this new machine.

The staff at the University really appreciated that the machine was easy to use and didn’t tire them out. They also liked that the steering wheel height could be adjusted for comfort and ergonomics for any user. And it was also mentioned that since no tools are required to remove the vac shoe, the in-line solution filter or the brush, little time was wasted when maintenance was required.

Stoneking had this to say about the Armada:

 • “I want first on the list for purchase when these come out.  You can have my [other machine] back.”

 • “In a 35,000 sq. ft. office area with carpet tiles, I spent 4 to 5 hours cleaning the hallways and between cubicles.  The [previous machine] would take over a week to do the same.”

 • “Three-times more cleaning productivity and 1/4 dry time as [our old machine].  I want one.”

Since the design validation, the University of Utah has purchased 12 Armada’s and uses each one every day. The staff finds them fun and enjoyable and, as a result, they get used more frequently, keeping the carpets even cleaner.
