Project Case

Rethinking vacuuming with the Robert Thomas AG

  • Academic Programs

Intro

Thanks to their powerful water filter function, Robert Thomas AG vacuum cleaners are a must-have for every household. Despite excellent cleaning results, many users found the device complicated and unpleasant to handle and clean. In the design thinking process, students from the HPI d-school developed a prototype of a vacuum cleaner that merges innovative technology with effortless comfort.

Challenge

How can the user experience of water filter vacuum cleaners be simplified with family households in mind?  Robert Thomas AG approached a team of students at the HPI d-school with this challenge. The long-established family business from North Rhine-Westphalia is known for its powerful vacuum cleaners with innovative water filter technology – particularly appreciated by allergy sufferers because even the finest dust is bound in the water. The goal was to further develop the model so that it is easier to use and clean up afterwards.  

Starting point

Although Robert Thomas AG's product range already offered many powerful appliances, the complicated operation and time-consuming cleaning of the vacuum cleaner were a real obstacle for many families. The HPI d-school student team discovered that many users found cleaning the device unpleasant and disgusting. Therefore, the key challenge lay in combining the high cleaning power of the company's water filter technology with the simple, hygienic handling of a bagged vacuum cleaner.  

Aha moments

Based on in-depth user research and product testing, the team developed a concept that turns dust, odors, and even liquids into a compact jelly block within seconds. This innovative idea has direct environmental benefits, because the block is compostable and can also be used as a water reservoir for potted plants. The device does not need to be opened or cleaned, making it far more hygienic and practical. This is how vacuuming with Thomas becomes a breeze. 

Impact

Robert Thomas AG was so impressed with the innovative prototype that it adopted it for its brand-new Thomas crooSer eco model. In addition to the original design, the device features a replaceable rubber bumper to protect furniture, a foot-operated nozzle change, a 360° swivel function, and a compact design so that dust doesn't stand a chance, even in the tightest corners. The quiet, maneuverable vacuum cleaner is now available on the market in a variety of colors. 
The collaboration with Robert Thomas AG shows how innovative ideas from HPI d-school students are taken up directly by companies and used to further develop a product – and how everyday routines can be turned into a positive experience with the help of Design Thinking.
