Lasting cooperation with a private school High demands met

Two hand-guided scrubber dryer machines and a ride-on vacuum sweeper provide the desired flexibility at an international school. They efficiently clean the interior and exterior areas of the modern building to maintain its representative appearance.The Strothoff International School in Dreieich first opened its doors in September 2009. The institution is a private day school for children from preschool up to the globally recognized international Abitur in the 12th grade. Currently, 310 students from 30 countries attend. The average class size is 14 students. “One of our great features – among other things – is that the entire school is optimally equipped in terms of technology,” reports Misael Klaic, who is responsible for Facility Management at the school. “We also place great value on the appearance of our entire campus.” From day one, robust cleaning machines from Hako helped make this a reality. One of these is a hand-guided scrubber dryer machine (Scrubmaster B30 CL), whose working width of 43 centimeters makes it very compact. It is complemented by a hand-guided scrubber dryer machine (Scrubmaster B45 CL TB) with a working width of 51 centimeters, which is excellent for cleaning large areas as well as a ride-on vacuum sweeper, especially for the schoolyard (Sweepmaster P980 R). Flexible cleaning processesWisag Gebäudereinigung Hessen Süd has been responsible for maintenance cleaning from day one as well. “We have five employees on-site daily,” reports Marc-Volker Zimmermann. He is responsible for maintaining the object. These five employees include one temporary staff member who can react spontaneously in the case of acute requirements. Four other employees begin with maintenance cleaning at 3:30 p.m., while school is still in session. They must be finished by 7:50 p.m. at the latest. Usually, both scrubber dryer machines are employed according to a specified schedule. “But this can change very quickly,” emphasizes Klaic. In the so-called Grand Meeting Room on the third floor, scheduled and unscheduled economic council meetings are held several times a month by the city of Dreieich. In these cases, more extensive arrangements are made to ensure that the rooms glisten. Laid with parquet flooring, a special polishing pad is used on the approximately 180 square meter area to improve the cleaning results, and thus, the school’s appearance, even more. In addition, the approximately 300 square meter foyer as well as the corridors, of which there are circa 600 square meters, must always be clean, not only for evening meetings, but also during school hours. All floors, whether stone, tile or wood, are wet-mopped daily as part of maintenance cleaning. Depending on the subsurface, the brush plate may need to be changed. This is simple: One touch of a button is sufficient to cleanly, quickly and easily exchange the respective tool. “The scrubber dryer machines are in use a good two hours every day; then the floor cleaning is done,” summarizes Zimmermann. Focus on chemistry and art rooms“The amount of dirt varies daily,” Klaic points out. Above all, in the preschool and primary school, there are true mountains of sand in the three sandboxes, which turn into mud when the kids play with water. And all of this gets into the ground floor of the primary school, sometimes even leaving its traces all the way up to the first floor. In winter, grit and slush also get into the foyer; in the spring it’s the pollen, which is noticeable throughout the entire building. The second and third floors are home to the slightly older pupils. “Here, there is much less dirt,” reports Klaic. The classrooms are usually laid with carpet. The science rooms have tile floors, while the art room has parquet. Experimentation with the most diverse chemical and physical substances as well as painting, crafts with paper and natural materials leave traces, from acids to paint splotches, which must be completely eliminated during maintenance cleaning. In the physics, chemistry and art room as well as floor corridors, the smaller of the two scrubber dryer machines is used. Due to its dimensions, it can be transported in the elevator. It is also so agile that it can even be used in rooms with cramped conditions. Due to its flat, projecting brush deck, it easily cleans under tables, closets and heaters. In the foyer and adjacent corridors, the building cleaners use the larger machine to perform the required services as quickly as possible. Both cleaning machines are simple to maneuver. In this area as well as on the upper floors, there are many seating possibilities. They can be easily bypassed. The company begins cleaning at 3:30 p.m. while school is still in session. Because students are sometimes in the building until 6:00 p.m. due to the wide variety of recreational activities, the noise level of the cleaning machines must account for this. In addition, the suction performance must be excellent. “It is imperative to prevent slipping accidents,” says Zimmermann. Students, teachers and administrators must not slip on the wet surfaces; the floors must be able to be walked on under all circumstances – even right after wet-cleaning. In this case, the suction foot ensures excellent vacuuming results, even when cornering, and thus the required safety on the floors. Schoolyard sweeperTwice a week, the ride-on vacuum sweeper – further equipped with a side-broom and two large garbage containers – is used to clean the approximately 3,500 square meter schoolyard. Two sandboxes and a large playground area with wood chips ensure great amounts of dirt. Featuring the standard Take-it-easy system, both containers can be individually and conveniently emptied. The driver does not have direct contact with the dirt. The easy-to-use container lift enables the filling level to be checked at any time or bulky materials to be manually thrown in. Tasks are always performed efficiently and well. The machine can also sweep very close to edges, which increases its efficiency. A speed-controlled gasoline engine minimizes the work noise in exterior areas. “This is important during school hours,” emphasizes Klaic once again. Good cooperation a prerequisite“Flexibility and reliability are number one on our agenda,” says Wisag branch manager Wolfgang Scherer about his company’s philosophy. “For this reason, we need robust cleaning machines. We also value excellent service and good on-site support. We must be able to reach our contact person day and night, or on weekends, for example. If one of the cleaning machines should malfunction, customer service must be on the spot as quickly as possible to make the necessary repairs or if necessary, provide us with a replacement. And this works reliably.” For many years, the building services company has worked with Hako. It uses scrubber dryers and vacuum sweepers of all sizes in the various objects it takes care of. “In the context of machine management, we offer customers the suitable cleaning machine for the object and task,” explains the Hako sales representative of the Rhine-Main branch, Wilhelm David. “We can thus guarantee our customers the highest efficiency and cleaning performance.” One thing is clear. Robust technology suited to the respective requirements is very necessary. “But our employees play the most important role. They ensure our success. Our on-site service employees are there from the first day of school on. They do their work reliably and well,” says Wolfgang Scherer in praise of his staff. “We all pull together and work as a team. Our clients confirm this repeatedly.” The good cooperation on all sides is also confirmed by Misael Klaic. “Whether it’s the basic cleaning tasks during the long school vacations, the daily maintenance or special cleaning operations, they are reliably completed. Our declared goal is that students feel comfortable with us. The external conditions are organized so that we always offer them a clean environment.” Michaela Heider-Peschel, free professional journalist | markus.targiel@holzmann-medien.de
