Before installation, the undersigned entered into a dialogue with their cleaners, where they were informed about the reason why it was desirable to try out this type of sensor technology. This led to them gaining an understanding of the project, as well as their participation during assembly, thus more ownership and commitment.

Already during the installation of the senors, we uncovered a number of deviations in the maintenance of carpet beaters in the buildings.

At the older school, it was discovered early on that none of the floor washing machines were in use. It then turned out that one was actually too big for the location, and the other needed repair. It was considered replacing the largest machine with a smaller one. Since the smallest machine is also not being used satisfactorily, there will still be no need to insert another one. The dust level at the school was not satisfactory, and this had a connection with the fact that the floor washing machines were not used sufficiently.

It was discovered that one of the cleaners used carpet banks only when the cleaning zone looked dirty. Otherwise, the use of these machines was satisfactory. It is "easier" to mop the floors instead of using a machine, according to the cleaners. There are great advantages to using floor washing machines, mainly for less strain on the body, and that the quality of cleaning is much better than with mopping. So a change of attitude is probably needed here.

We made the biggest discovery at the newer school. Here, the cleaners each have their own floor washing machine, 4 units, and there are also 2 larger machines in the associated sports hall. In addition, there are 7 carpet banks located scattered throughout the building.

Here the cleaners are good at using the carpet beaters, but in the entrance area, where tenants use the carpet beaters, this is not satisfactorily used as recommended. Here, information must be given to the users, so that the time spent using the carpet beater increases.

As for the floor washing machines in the building, only the two largest were used weekly, 1-2 times in the sports hall. This was raised with the cleaners, and they informed that the four remaining floor washing machines are mainly only used during the school holidays. The maintenance cost of machines will increase considerably if the machines are not in regular use. The conclusion we reached here was that they have at least 2 floor washing machines too many here. These will be moved to other buildings in the area where the need is greater.

At this school, the individual classrooms where users have complained about bad air and indoor climate. The measurements we have received from the air meters indicate that there are daily levels above the limit value.

The humidity was relatively low, and in conjunction with a high Co2 level, this would likely cause headaches, sore throats and dry lips. We take such information on to operations to uncover any errors or deficiencies in the ventilation system.
