With our maintenance cleaning services, we make a significant contribution to the care and value retention of the interior and exterior areas of your building. In order to meet your needs for cleanliness in the area of maintenance cleaning in the best possible way, we develop
individual service specifications and determine performance figures that can also be realistically implemented. Is it an on-demand or a visual cleaning? What is the degree of soiling? What type of room use is involved? Or are there special regulators for the respective cleaning intervals?
With transparent calculations and detailed service specifications, we guarantee you quality at economical prices.


With the Dorfner Module System 2.0 and its individual options, we guarantee our customers maximum flexibility in terms of economy and practicality. Essential components of the system are individually designable cleaning carts, a cleaning chemical that can be dosed as needed, and a sophisticated cleaning method with high-quality microfiber cleaning textiles for maintenance cleaning.

If it is to be free of germs and particles, it takes more than conscientious cleaning of surfaces. That is why cleanroom cleaning is considered the supreme discipline of building cleaning. In addition to professional decontamination and disinfection, our cleanroom team, which has many years of experience and sound know-how, offers a comprehensive range of services. This applies to all cleanliness classes from GMP to all ISO areas.

Our vacuum, sweeping and scrubbing robots are no longer in the test phase! They support the cleaning staff on site by taking over monotonous and physically demanding tasks. They measure the area to be cleaned using cameras, ultrasound and lidar. They automatically detect obstacles and people and stop cleaning immediately in an emergency. During active use, these intelligent machines also require regular maintenance and care to ensure their high performance and reliability. We take care of the set-up, correct configuration and system-specific maintenance for you.

During an initial inspection, our Robotics team determines where and how a robot can be optimally deployed. We gather the most important information in advance so that we can integrate the robot into your building as quickly as possible. This also gives us the first opportunity to tailor the use of the robot to your needs. We are manufacturer-independent and can use the robots that are best suited to your premises.

With their futuristic look and sophisticated technology, they are a real eye-catcher that expresses innovation and efficiency

Our robotics department intensively examines all innovations on the market. The limits of the respective systems are determined in intensive tests and the cleaning results are compared in a constant environment. This gives us an overview of all innovations and further developments on the market. This enables us to react quickly at all times and offer you the best solutions.
