At UNL parking garages, the Cyclone rider pressure washer reduces labor and leaves a wake of 'clean' in its path

The case study, "At UNL parking garages, the Cyclone rider pressure washer reduces labor and leaves a wake of 'clean' in its path," from Advance tells how the University of Nebraska-Lincoln eliminated its need for contract cleaning for its parking garages. Prior to using Advance's Cyclone™ 4500 rider pressure washer, UNL's parking garages were cleaned by a local contractor using the University's walk-behind pressure washers. Since the Cyclone provides better productivity than walk-behinds and only requires one person to operate, UNL is now able to keep the job in-house, while also seeing cleaner surfaces on its parking ramps.

Once every summer, three parking garages with nearly 4,000 stalls at the University of Nebraska-Lincoln (UNL) have to be cleaned of dirt, oil and residue that vehicles deposit all year long. Given the heavy use of the garages and a relatively narrow annual cleaning window, the University has to make its opportunity to clean count. Bill Manning, night manager of University Parking and Transit Services, relies on the Cyclone 4500™ rider pressure washer from Advance to ensure that the University makes the most of its summer cleaning routine.

Manning realized that the University's conventional pressure-washing equipment wasn't up to the task when he found the floor of a garage still caked with dirt, oil and buildup the day after the scheduled cleaning. When he confirmed the yearly washing had taken place, he set about finding a replacement for the old equipment. After researching several options, he saw an impromptu Cyclone demonstration on one of the loading docks at the Dallas Convention Center while attending the International Parking Institute Conference & Expo. Right then and there, Manning knew the Cyclone 4500 was the machine for UNL.

"It was amazing what the Cyclone did as far as cleaning all the rust and oil and everything else that was on the floor of that loading dock," Manning said. "I couldn't believe how much it cleaned in just one pass. We decided to pursue the purchase of the Cyclone based on that one demonstration."

The Cyclone's cleaning performance has made a big difference in removing dirt, oil and other build-up from the floors of UNL's parking garages. The Cyclone heats water to 160 degrees F, then unleashes it over a 34-inch cleaning path at 4,000 pounds of pressure per square inch. The machine's patented cleaning and recovery head spins hydraulically and tips to within a quarter-inch of the ground, which allows the Cyclone to clean surfaces ranging from flat to uneven. The result: "When the crew gets done with the Cyclone, you can tell where they have cleaned," Manning said.
