Leading the way for 60 years..

1) Who is the founder of UNGER?
1964, United States of America. Highly motivated, the young glass cleaner Henry Unger decides to realise his dream. He emigrates to Hamburg - with the new innovations for window cleaning from the USA in his luggage. His colleagues in Germany were so enthusiastic about the latter that Henry Unger, with the support of his wife Barbara, seized his chance and founded UNGER: From his mother-in-law's small attic, he built up the company that today spans the entire globe.

2) What is UNGER's philosophy?
In close dialogue with glass and building cleaners, we always strive to develop the best cleaning solutions for optimum results. Together we are working on the new generation of innovative possibilities to make cleaning even easier, safer and more efficient in the future.

3) Has UNGER's philosophy changed over time?
No. On the contrary, it has become more firmly established. UNGER has always been characterised by the continuous pursuit of innovation. A look back at our 60-year success story proves this: We keep developing innovative cleaning tools and keep finding new solutions for numerous cleaning requirements. In the future, we will continue to develop products that bring you, the glass and building cleaners, real benefits.

4) What does the UNGER logo stand for and how has it evolved over the years?
Our logo is characterised by the shape of a stylised window squeegee - THE recognition feature of every professional glass and building cleaner and THE pulse of UNGER. Here you can see the development of our logo over the years:

 5) Where does the claim "Quality Tools for Smart Cleaning" come from?
We work with business partners in over 80 countries around the world. Our customers have the same expectations everywhere: The best cleaning results! The highest safety standards! Minimisation of unnecessary effort! This is exactly what we work on every day, regardless of culture, language and location. And that's why we can promise: UNGER cleaning tools, these are "Quality Tools for Smart Cleaning"!

UNGER is an owner-managed family business and is now run by the second generation: Dane, Jan and Mark. The brothers continue to uphold the principles of quality, trust and customer service, which has enabled them to develop UNGER into an international group that is continuously driven forward by a combination of tradition and innovation.

First and foremost, our close relationships with our partners and users and our development of innovative products that are geared towards your needs. Our top priority is always improving productivity and safety. Henry Unger's passion and euphoria are kept alive around the world today by our employees and the “UNGER spirit”.

UNGER Germany GmbH’s headquarters is located in Solingen, in the heart of the Bergisches Land region and halfway between the cities of Düsseldorf and Cologne. This industrial region has excellent infrastructure, which enables us to operate internationally and supply customers worldwide. We also have sites in other EU countries, the UK and the USA.

Solingen is widely known for its metal industry – and a large proportion of our cleaning tools were formerly made of metal. Since 2013, UNGER has been located at Piepersberg 44, where our Centre of Excellence houses research facilities, a training centre, a showroom and our logistics and production centre, which covers around 4,500 square metres.

We founded our business in the USA (UNGER Enterprises) in Mount Vernon in 1978 and moved it to Bridgeport in Connecticut nine years later. We have expanded the company headquarters there several times – because as UNGER grows as a company, so does the investment in our global business.

11) Which regions are serviced from which location?
UNGER Enterprises conducts its business in the USA, South America and Canada from Bridgeport in Connecticut, while all other regions worldwide fall under the responsibility of UNGER Global in Solingen.

The average age at UNGER Germany is 44 years, which corresponds exactly to the average age of employees in Germany. Our youngest employee is currently 19 years old, while our oldest has already celebrated his 65th birthday.

We have achieved a great deal! In addition to numerous new products for pure water cleaning (such as the HydroPower Ultra, RO pure water filter and nLITE), traditional glass cleaning (Green Label, OptiLoc and others), interior cleaning (Stingray) and floor cleaning (erGO! clean), we are extremely proud of our digital channels which were revamped in 2019. Our fresh looking, new website, Facebook and YouTube in multiple languages, various newsletters and Instagram help us stay in touch with you!

14) How long has the longest employee been with UNGER?
Some employees have already been working at UNGER for a long time. The employee who has been here the longest has been on board for 40 years now. And we are pleased to say congratulations on this fantastic anniversary!

15) Who is currently on the UNGER management team?
It’s important to us that managers recognise and promote the strengths of each employee to make UNGER stronger as a whole. Our hierarchies are extremely flat and everyone contributes to our success. You can find our current management overview here:

16) Who were the first retailers to sell UNGER products?
Walter Hammel and his colleague Walter Hasenkampf were the first to distribute UNGER products and the “American method” with washer, squeegee and pole. With their help, Henry Unger managed to establish his method in Germany and achieve a high level of recognition among building cleaners.

17) What is the process like from ordering to arriving at your door?
If your retailer orders products from UNGER Customer Service, their order is automatically sent to the dispatch department. While the person is still receiving his or her order confirmation, an employee in the warehouse is already packing the items so that they can be dispatched quickly. This ensures that your specialist retailer always has UNGER products in stock and that you can try out the tools live on site.

18) Which retailer is the furthest away - and which is the closest?
The shortest delivery route for UNGER products is to Hygienic in Wuppertal, which is only around four kilometres away from Solingen. Filta in New Zealand, the retailer with the longest delivery route, is 4,500 times further away: The UNGER products travel almost 18,140 kilometres around the world to facilitate glass and building cleaning in the distant city of Auckland.

19) What was the first UNGER product?
UNGER has set milestones with numerous innovations over the past 60 years. One window cleaning tool that has been highly valued by cleaning professionals from the very beginning is the S squeegee. It achieved its first success in 1966 because it used stainless steel instead of brass and a spring mechanism for quick channel replacement.

20) What was the first product series?
Launched in 1973, OptiLoc was the first product series from UNGER. Tools could be easily and securely attached to the telescopic poles. Commercial cleaners were able to clean high windows with a washer and window squeegee without a ladder 52 years ago, as they still do today, because we have optimised the OptiLoc telescopic poles time and time again. They are a real favourite for cleaning work at heights.

The S-squeegee in 1966 was the beginning of what drives us forward and today we can proudly look back on innovations such as the nLITE telescopic poles and the HydroPower pure water cleaning system. Our goal has been and is to develop efficient and solution-oriented products that help you with all challenges – that will never change at UNGER!

The success story of UNGER tools began with the S-squeegee. Since then, we have developed many innovative solutions for commercial cleaning – most recently we launched the Green Label glass microfibre cloth on 2 May. We have set out when UNGER developed which innovation for you on a timeline!

23) How many product lines are there and what are they called?
To date, UNGER has introduced an impressive variety of product lines, each with its own advantages. These include the series: HydroPower, nLITE, ErgoTec, Ninja, StripWasher, OptiLoc, TelePlus, UniTec, Stingray, NiftyNabber, erGO!, OmniClean, SmartColor, WaterWand, AquaDozer, StarDuster, etc..

Thanks to carbon fibre technology, UNGER was able to fulfil the desire to combine water-fed poles with a modular telescopic pole. This is how the “nLite” system was created, a play on words made up of the components “light” and “enlightenment” that illustrates the lightness and innovation of the poles. Not only the product itself, but also the name has evolved through improvements – but the innovative power of “nLITE” remains.

In order to offer a comprehensive system, we began developing our own system in 2014, the HydroPower DI system, which not only improved performance but also handling. “Hydro” stands for water filtration, while “Power” emphasises the improved performance of the pure water filter. Fun fact: the idea for this filter actually came about on a beer mat.

Earlier window squeegees, mostly metal ones, were robust but not very ergonomic. In the 1990s, UNGER revolutionised the squeegee with the ErgoTec by replacing metal with plastic. This made the tool lighter, more ergonomic and adapted to the human hand, allowing for gentler cleaning.

UNGER tools all aim to be efficient and ergonomic to make your work easier. The safety aspect is just as important and OptiLoc telescopic poles fulfil this requirement. Instead of having to climb ladders, commercial cleaners can now safely clean surfaces at height from the ground. Thanks to the safety cone, UNGER tools sit firmly on the pole, minimising the risk of injury.

The robust and powerful ErgoTec window squeegee was a success right from the start. For even more flexible handling, UNGER also developed the ErgoTec Ninja, which is equipped with a larger ergonomic 2-component handle. More rubberised surfaces ensure optimum grip. The clip system introduced in 2011, which securely holds channels up to one metre long, explains the product name: the ErgoTec Ninja is elegantly reminiscent of a ninja sword and transfers its strength to our squeegee.

UNGER has the ideal tools in its portfolio not only for glass cleaning, but also for floor cleaning. The erGO! clean revolutionises the classic floor mop and floor spraying systems. By analysing the movements and stress points during floor cleaning, an ergonomic, body-friendly system has been developed that has enabled the typical S-movement with minimum effort since 2018.

Our absolute top seller is the ErgoTec window squeegee – it is the unrivalled heart of UNGER and a must-have for commercial cleaners. But even if you have decided on your favourite, we are always working on new tools that will inspire you and support you in your work. Stay tuned!

31) Which is the lightest UNGER tool?
Ergonomics is our top priority when it comes to our tools, as this is the only way they can provide you with optimum support at work. Over the years, we have optimised the weight of many products to protect your health. The ErgoTec carbon handle weighs just 73 grams. At 10 grams, the lightest glass scraper is the mini scraper.

32) Which UNGER tool is the heaviest?
Everything conveniently in one place: the autonomous HydroPower RO XXL trailer with reverse osmosis filter and 650-litre water tank weighs 800 kilograms and combines everything needed for pure water cleaning in one system.

In 2006, with the HiFlo pure water system, UNGER developed a system for the first time that enabled commercial cleaners to clean with pure water using water fed poles. The current nLITE system is constantly being developed further so that our tools can optimally support you in your work.

In one continuous piece and without extensions, UNGER’s longest pole measures 10 metres: the TelePlus telescopic pole. This allows windows to be cleaned with precision at lofty heights. The nLite Connect Ultra HiMod Carbon telescopic pole achieves an impressive length of 19.5 metres including extensions.

The most powerful filter for pure water production is the HiFlo RO60S. With an impressively high water production of over 750 litres per hour, it is particularly suitable for large areas. The high-performance filter is ideal for a cleaning professional with increased water output or for two employees without loss of capacity.

The journey of the HydroPower Ultra filter began in 2006, when it became clear that a high-performance filter was essential for the UNGER cleaning system. After many innovations and learning from early models, in 2014 we developed the ground-breaking HydroPower DI system with easier resin change and higher performance. Today, the HydroPower Ultra is built in Solingen and has revolutionised pure water technology worldwide.

This is our Green Label window squeegee, which we launched in 2023. Like our entire Green Label range, it stands for a green, new generation and a sustainable era of tools. We have since added many more tools to the world’s first range of sustainably certified products for classic glass cleaning. Discover it here!

Every year we extend invitations to more than 1,500 events. These include the Demo Days, where we present the UNGER tools, as well as training courses and the like. Our events are usually organised by the regional Sales Managers. Do you already know yours personally?

Since 2007, UNGER has received 15 awards, all of which we are very proud of! These include prestigious design awards such as the Red Dot Design Award for the UNGER Stingray in 2017 as well as coveted awards for our product innovations. The erGO! clean floor cleaning system has won six awards – including the Inclean Innovation Award, the Plus X Award and the ISSA USA Innovation Award. Our second generation nLITE system also received the latter in 2022.

Our nLITE portfolio offers the greatest variety of products with water-fed poles, brushes, angle adapters and many other modules for pure water cleaning – closely followed by the ErgoTec Ninja series for traditional window cleaning.

At UNGER, we demonstrate responsibility both with our uncompromisingly green Green Label range – the first with sustainably certified cleaning tools for traditional window cleaning – and through the constant optimisation of processes. We strive continuously to contribute to sustainable business practices, social commitment and a more responsible use of natural resources. We currently hold the EcoVadis Bronze certificate in recognition of this.

UNGER has been around for 60 years and we have been represented at trade fairs for almost 50 years. Back in the 1970s, our founder Henry Unger presented his systems and products directly to trade visitors at the Cologne Hardware Fair. RT Reinigungstechnik and Interclean in Amsterdam followed in the 1980s. Since the 1990s, we have also been represented at international trade fairs such as Pulire in Milan, Europropre in Paris, the Cleaning Show in London and other trade fairs.

We attend numerous trade fairs to give you the opportunity to discover and try out our tools for yourself. Among these, we regularly attend Interclean, ISSA Show North America, IWCA, CMS, Pulire and Europropre. This year, you were able to catch up with us at Interclean and we’ll also be attending various other trade fairs in the coming year. Will we see you there?

Anna-Lena for Europe and Alexis for the USA are responsible for organising the trade fairs, including the design of the UNGER stand. Together with the marketing team, local sales managers and trade fair builders, they ensure an exceptional visitor experience. You can experience our products in action with interactive highlights such as the two large demo windows, where you can try out both pure water cleaning tools and traditional window cleaning tools.

In addition to the international trade fairs, we also have many other events that our sales representatives carry out. You can participate in numerous in-house fairs, training courses, demo days and virtual demo days. We keep you up to date on our events through our social media channels and our website. Follow us to stay informed!

A new product idea is usually created in close interaction with you as part of regular joint workshops. We gather exciting ideas and develop them alongside our global team. It is particularly important to us that the products serve you well, which is why you are able to test them afterwards. This allows us to optimise our tools to make your work even easier!

Yes! We are always looking for people to test our tools as technical feedback plays a major role in product development. We are only able to develop the best and most innovative tools with your input. Are you interested in helping us? Then register as a product tester here!

A dedicated and experienced team is responsible for quality control at UNGER. They ensure that all products meet the highest standards before they are made available to you worldwide. For us, this standard is a matter of course – because it ensures your satisfaction and that is particularly important to us.

Our customer service is available to retailers in six languages: German, English, French, Italian, Spanish and Dutch. We do everything we can to provide specialist retailers with the best possible support – for all questions and concerns, individually and in their preferred language. In this way, we ensure that our partners around the world always receive the right solution and the best possible support.

UNGER is a multinational company that is proud of its cultural diversity – the number is hard to define exactly. What is more important to us: Our open company mentality is only possible thanks to the co-operation of open-minded people. As green as our UNGER everyday life is, so vibrant is our culture – diversity and cultural richness are truly lived here with us!

At UNGER, we always prioritise authenticity. That is why in our videos and photo shoots we only work with real cleaning specialists who live and breathe the trade. We work with local professionals as well as cleaning specialists from all over the world.

Our Packsize Machine ensures sustainable, customised packaging. This involves creating individual, tailor-made packaging that uses space efficiently. This means that no space is wasted and we can ensure that your products arrive safely and compactly. A plus for the environment and efficiency!

At the UNGER headquarters in Solingen, we drink 1.14 kg of coffee every day, which equates to around 8 kg per week. In addition, 58 x 0.75 litre bottles of water every week ensure that we are bursting with ideas!

“Show what you can do! Be yourself! Be part of the team” – three sentences that perfectly describe our corporate culture. At UNGER we work as equals and support each other. Team-building events, barbecues and breakfasts are just as much a part of this as our open-door mentality. We are a global team that acts as a family. See for yourself!

UNGER stands for constant innovation and high-quality tools that offer commercial cleaners real added value in their everyday work. Safety and ergonomics are just as important to us as communicating with you. From professional to professional, we create a win-win situation: Your wishes are incorporated into our products. Listen to what our customers say.

Sustainability is playing an increasingly important role in commercial cleaning. That’s why at UNGER we are committed to environmentally friendly solutions such as the Green Label range. At the same time, automation and digitalisation are coming into focus due to the shortage of skilled workers – for example through the use of drones and robotics. Efficiency and safety are still of great importance. UNGER develops modular and ergonomic tools for you that combine both.

We have already prepared exciting new products and promotions for you for 2025! You can also expect some innovations that will make working with UNGER even easier. We are also particularly looking forward to participating in renowned trade fairs: You will find us next year at IWCA, Europropre, Pulire and CMS. We are looking forward to 2025 – together with you, of course!
