We are more than just a water pump company. Through our solutions and services, we touch millions and millions of people every day, without most even noticing. And with that comes great responsibility. A responsibility to respect, protect and advance the flow of water for people, businesses and the planet. Because at Grundfos, we believe that every drop contains infinite possibilities, and that water has the power to change the world. 

The UV-C disinfection robot (Mediland Enterprise Corporation, Taoyuan City, Taiwan) uses amalgam lamps (UV lamp NNI / XL Niederdruck VUV Strahler) and protective reflector technology to generate high-energy, broad-spectrum ultraviolet light (UV-C &#x; nm). The manufacturer of the lamps declares in the technical data sheet that the lamps have a filter that blocks radiation between &#x; nm, eliminating the possibility of producing ozone as a by-product of UV-C radiation. The UV-C device uses min disinfection cycles and multiple positions with minimal distances from high-touch surfaces. Due to the use of high-intensity UV-C radiation, the device must operate in unoccupied rooms. There are multi-motion sensors that shut off the device if any movement is detected inside the room being disinfected or if the door is accidentally opened. When the robot operates in accordance with these procedures, the manufacturer declares that the amalgam lamps produce no ozone gas and leave no toxic residues.

In the OT and ICU, where the limit for hygiene quality is defined by national guidelines, respectively, % (/) and % (/) of the surface samples resulted in being non-compliant after SOP. In the ward rooms, according to the standard reported in the literature, % (/) of the sampled sites resulted in being non-compliant. All of the samples were compliant after UV-C disinfection. In all of the settings, % (/) of the sampled points received a medium UV-C dose of mJ/cm

A prospective open-labelled cross-over study was conducted in a -bed teaching hospital in Italy from April to June . To evaluate the effectiveness of the UV-C disinfection robot in reducing environmental contamination, sampling was performed in four different critical areas: single occupancy ward room, intensive care unit (ICU) isolation room occupied for a minimum of h, and operating theaters (OTs).

The role of the environment, particularly of high-touch surfaces in the patient&#x;s room (e.g., bedrails, over-bed tables, and call-buttons) and reusable care equipment that is moved between rooms, has been demonstrated to be fundamental in the transmission of healthcare-related infections. Together with standard precautions and the application of good practices in invasive procedures, environmental cleaning and disinfection represents one of the three pillars of infection risk prevention in healthcare settings.
