KOLO™ Clean is a mobile app primarily for on-the-go custodial staff. It’s part of GP PRO’s KOLO™ Smart Monitoring System, which joins proprietary sensor and communication technology with the industry-leading dependability of enMotion® and Compact® dispensers. KOLO™ System-enabled paper towel, toilet paper and soap/sanitizer dispensers connect to KOLO™ Clean via a proprietary cloud-based IoT platform. The technology assesses when products are low or out, when paper is jammed or when batteries need replacing, and communicates that information via timely KOLO Clean™ alerts and status reports to custodians and facility managers. KOLO™ Clean helps you: • Increase user satisfaction, because your custodians can proactively replenish products and help you avoid potential problems before they become complaints • Boost labor efficiency and productivity, because you have the right employees doing the right tasks at the right time • Ensure greater usage of products and decreased discarding of partially used rolls, because your custodians receive timely notifications when products need refilling And through KOLO™ Clean, the KOLO™ System’s advanced sensors and sensing technology let you track products down to a ≈3% level. That allows the Estimated Time to Run-Out (ETR), a key metric of the System, to help determine which task should be tackled first. That helps you make the best use of your custodians’ time, and maximize your operational efficiency.
