Northern Arizona University Masters Team Cleaning with Tools, Techniques and Janitor Cart from Unger Enterprises

At the time that Northern Arizona University (NAU) engaged the Unger team, it had experienced significant growth over the past 10 years, nearly doubling its number of students in the past decade to more than 21,000 on the flagship campus.

A growth story is excellent for admissions and student life but can be challenging for one department in particular: Facility Services. Director of operations Scott Perelstein, who has been with NAU for nine years, explained the growth in population caused more construction, new buildings and a need to adapt to serving more people in these new and existing spaces. The 120 full-time custodial staff that supports cleaning across campus needed to change their approach to become more efficient at keeping the whole campus looking its best.

Improving the cleanliness of the environment was also a key priority for university President Rita Cheng, who wanted to see quick changes in the quality of cleanliness. To solve this challenge, the facility services team chose a team cleaning approach.


Both zone and team cleaning approaches are designed to increase efficiency in your cleaning procedures, and ultimately save money. Whereas zone cleaning means one employee performs all tasks for a specific floor or section of a building, team cleaning groups related tasks. Rather than cleaning a specific area, each individual on your custodial staff performs a specific task.


Implementing team cleaning at NAU required a significant cultural shift in addition to changes in processes and procedures. Many custodians have been working at the university for 30+ years and “didn’t know what they didn’t know,” Perelstein explained.

To ensure the necessary changes would be lasting and successful, NAU officials realized they would need outside help. Tim Poskin of Cleaning Management Concepts was with them through every stage of the process. Cleaning Management Concepts uses a seven-step process to achieve Cleaning Change Solutions™. The first step is an initial assessment to understand where you stand. Poskin introduced the team to the benefits of re-tooling with Unger Enterprises. Poskin described the team as “passionately frustrated” when he arrived, wanting to improve but not knowing how.


Until now, NAU’s facility cleaning solution consisted of generalist cleaners assigned to specific building or floors completing a variety of tasks, including floor cleaning, dusting, vacuuming and restroom care. Custodians could be assigned to multiple buildings located throughout campus or be responsible for a section of a building where other custodians were already working. The process was inefficient and exhausting and lacked a holistic approach to assignments.

Commercial cleaning tools were another challenge. Custodians were equipped with dated string mops, cotton rags and a cumbersome janitorial cart that often didn’t fit through doorways or accommodate tools. The availability and condition of mop buckets and other tools varied depending on the building.

Best practices for facility cleaning didn’t exist. With NAU being the largest employer in Flagstaff, the university didn’t have any examples to look to in managing such a large task. By bringing in the team from Cleaning Management Concepts and professional tools and equipment from Unger Enterprises for outside support, NAU adapted its disjointed and inconsistent cleaning process to a team cleaning approach.


Part of the cleaning transformation included ditching NAU’s old mops, cumbersome cleaning carts and varying mop buckets in favor of the Unger RestroomRx janitor cart, an all-in-one restroom cleaning system designed for custodians, by custodians. The system provides a janitor cart with vinyl trash bags, all tool clips and holders, a 32- or 16-quart dual bucket system, mop holder, color-coded Micro Mop 15.0, telescopic dustpan, NiftyNabber® litter removal tool, swivel brush, toilet bowl brush and duster so custodians have everything they need at the beginning of their shift.

The Unger RestroomRx janitor cart neatly holds all tools in place, ensures access to the right tool for the right job, increases worker safety by keeping the bucket on the cart and—the good news for newly constructed buildings – fits easily through doorways to eliminate dings and dents. Color coded tools prevent cross-contamination, streamline training and ensure easy identification of what comes next. Poskin chose Unger for the project because they are “best in class and best in tolerance, tools and equipment.”


The process of moving from a system of individuals working alone in isolated settings to working together as a team of specialists to drive change and efficiency had a huge impact. There are now four types of specialists, each focusing on a singular task such as a restroom specialist. The specialist now handles all the restrooms over a large area while no longer having to cover dusting and vacuuming in non-restroom areas. The roles work in a domino fashion with each job impacting the next, perpetuating building accountability and creating a true team mentality while increasing efficiency.

Tasks have been adjusted to prevent team members from following the exact same process every day. Some days focus on deep cleaning while others focus on lighter spot cleaning, allowing for more variety and project work opportunities. Perelstein hopes the flexible schedule will help with absenteeism and keep custodians engaged, leading to minimal intervention from supervisors.


Training is critical to successful implementation. The first training involved meeting with custodians to introduce them to the new team cleaning approach and set the stage for the cultural shift. All team members went through two days of custodial cleaning specialist skills training on the processes, learning Level 1 skills and sampling new cleaning cart and tools. Start-up of the new team began the day after the cleaning workers graduated from class with the team regrouping 30 days later to discuss what worked and what needed to be tweaked. Level 2 training was rolled out after 60-90 days, focusing on the project work and less frequent tasks.

The new Unger tools were a hit at the training. When the Unger RestroomRx janitor cart was rolled out for the first-time during boot camp, custodian Dennis Gant, who has been with NAU since December 2017, stood up in the middle of the discussion and began walking around the cart in awe, describing it as a janitor cart that “makes you want to tuck your shirt in.” In addition to the tools and training, the support of the administration has been critical to success. Poskin explains that while he usually works with universities at the director level, it was unique to have everyone from the president all the way down to the custodians engaged in the process.


The full program was rolled out across all 119 buildings on 5.6 million square feet of the campus, with plans to extend it to residential buildings.

Consistency has been the biggest improvement from the new program. NAU has seen significant improvements in its before and after housekeeping assessments performed by third-party company Sightlines. The university significantly improved its rating on an appearance rating scale, moving from a 4.5 or 5 rating on most buildings to a 3.5 or higher on the 5-point scale (with 5 being the worst). NAU also has seen significant efficiency improvements. Perelstein said the university has “redefined where and how people work.”

Another gauge of success has been the feedback from all levels of the organization, from President Cheng and the administration to the vice president of capital planning and campus operations to the facility services team and building managers. “Those building managers who have it are bragging about it and those who don’t are pining for it,” Perelstein said. The highest-performing custodians are the most enthusiastic and see it as “being part of something bigger than themselves” and something they can be proud of, he adds.


When asked about the keys to the university’s success with team cleaning, Perelstein cites the following:

  • Engaging outside support from subject matter experts who have solved the same challenges for many years versus going it alone
  • Having internal support from the administration and commitment from the top so they can invest the right time and resources to be true to the model
  • Being open to culture change, as this approach changed everything about the custodian’s day
  • Being all in – to the tools, approach, training and processes
  • Using the best professional cleaning tools to ensure a quality clean while increasing efficiency


“We looked at this change as an overwhelming behemoth for a long time, and that held us back in the past,” Perelstein said. “Once we committed to the process and engaged the right team, we immediately began seeing results and feeling good about it. I’m proud of our team and how everyone has adapted, from the administration to the custodians.”

Next on the cleaning plan for NAU will be the completion of the academic building phase and then to evaluate the residential building rollout. The team has learned a lot since kicking off the team cleaning process, but it’s clear the learning won’t stop when the implementation is complete. “Cleaning is an ongoing process and will continue to evolve as our campus evolves. We’re at the beginning of our clean trajectory and are excited to see the results that come next,” Perelstein added.

Now when others are looking for best practices, they can take lessons in cleaning success from NAU, who has mastered team cleaning from “A-Z.”

Innovative Campus Cleaning Equipment

Beyond what NAU did to accomplish its goals with team cleaning, overall, a clean educational facility gives students and staff a deep sense of pride in their surroundings, and a clear mind to pursue the day’s demands. It also diminishes clutter and contamination, greatly reducing the risk of illness and injury to anyone working or living within your facility. Unger has over 50 years’ experience in supporting both local school districts and larger educational institutions implement successfully cleaning programs using the most innovative commercial cleaning tools.
