The jungle of cleaning quality audits: DKS, MKS and the RQMS

As a cleaning company you know how important it is to keep the quality of cleaning per location at the best possible level. It is your aim to keep clients and users satisfied with good hygiene. In addition, each client has its own requirements for the cleaning. Your clients consist of offices, hospitals and perhaps also holiday parks. You want to make sure that customers appreciate your guidelines and see the quality they can ensure. To guarantee a high cleaning quality and optimise the performance of your organisation, you can use different cleaning quality measurement systems. Which one matches your organisation? Where should you pay attention and what are the differences? We have listed the following systems for you: DKS, MKS and RQMS.
Three different auditing systems in a row: DKS, MKS & RQMS


The Dagelijks Controle Systeem (DKS) is a random sample auditing method with which cleaning can be audited and assessed. The purpose of the DKS is to gain insight into the quality of the cleaning process. Identified deviations provide insight into the areas in which your employees can use guidance, so that you can manage them and thus improve the quality of the cleaning. 

When creating a DKS definition in the Leviy Dashboard, you can configure different rooms and elements to be audited. While performing a DKS audit you can register the assessment of each room using the App. When a deviation is detected, it can be registered as a “Dirty”, “Method” or “Periodic” error. If you regularly perform a DKS audit, there is a good chance that the cleaning quality will be assessed positively during an external quality audit. 


An MKS audit is similar to a DKS audit in many ways, but there are some differences. Just like a DKS, you can use an MKS at different locations and measure the quality against specific cleaning requirements. The DKS is generally used as an internal measuring instrument. The MKS audit can be compared with a VSR audit. In contrast to the DKS, the MKS works with point deduction. An MKS audit can also be configured in the Leviy Dashboard and performed with the App. 

The MKS is made up of a number of arithmetical components: 

  • Room categories
  • Weighting factors 
  • Elements 
  • Points deduction 
  • Fatal questions

The MKS comprises a number of room categories and specific elements are configured for each room category. Each element generates a certain point deduction, the options are:  

  • 0.25 
  • 0.50 
  • 0.75 
  • 1.0

In addition, each room category is given a weighting factor between 1 and 10. You can give different weighting factors for each room category per organisation. For example, The ‘Sanitary’ room category can have a heavier weighting factor than the ‘Traffic’ room category. In this case, the score for the ‘Sanitary’ room category has a higher weighting factor for the MKS. It is also possible to set up ‘Fatal questions’, by which a room is rejected as a whole in the event of deviances.

Starting points for calculating the score:

  • The MKS assumes that every room initially scores a 10.
  • For each element which is rejected within a room, points are subtracted from the initial score (10).
  • The score of an assessed room shall be included in the final score of the MKS according to the configured weighting factor.
  • A room in which a fatal question have been answered positively scores a 0 regardless of the number of rejected elements at all times.
A detailed analysis of the DKS audit results


RQMS stands for Result-oriented Quality Management System and is a certified quality auditing method in accordance with the BS EN 13549:2001 standard. The audit is conducted through random sampling with use of the RQMS App and Dashboard. When performing an RQMS quality audit, you assess the quality of cleaning at element level, for example a floor, chair or desk. For each audit, the Leviy RQMS App displays a structured room list obtained by an algorithm, which is in accordance with the standard, to determine the sample. In this way, the auditor is able to objectively audit what has been assigned to him via the sample. 

Within the RQMS, the different rooms in the building are divided into predefined room categories. In order to use the correct quality levels for each group, the elements of each room category are subdivided into assessment groups on the basis of the cleaning schedule.

When performing the audit, deviations per element can be registered in order to determine the current quality level. Any deviations on the elements are rejected on the basis of three predefined error types. After the assessment you can view the results of the RQMS audits per building in the Leviy Dashboard and share them with the client if required.

Digital audits via App and Dashboard

There is definitely a difference between the quality measurement systems. Which one matches your organisation depends on your goals and the requirements of your clients. With the Leviy App and Dashboard, you can digitally plan, perform and view the various audits. Leviy Analytics will help you to draw conclusions from the results obtained. These conclusions can serve as a measurable starting point for improvement plans and strategic choices.
