About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

HAUSPROFI
Robotic lawn mower replacement blades

Product description of the manufacturer

The HAUSPROFI titanium robotic lawnmower replacement blades are high-quality replacement blades that are suitable for a wide range of robotic lawnmowers. Made from stainless steel and coated with titanium, they promise increased durability and precise cutting results. The blades are ground on both sides and have a thickness of 0.75 mm, which ensures a stable and efficient cutting performance. The scope of delivery includes 30 blades, matching screws and a practical storage box with compartments.

One disadvantage is that the screws supplied do not fit the holes in the robotic lawnmower exactly.

  • High compatibility with various robotic lawnmower models
  • Durable due to titanium coating
  • Precise cut for an even lawn appearance
  • Screws supplied do not fit exactly

The blades are made of stainless steel and have a titanium coating, which provides additional hardness and durability. With a thickness of 0.75 mm and a weight of approx. 3.1 g per blade, they are robust and stable. The double-sided sharpening and precise grinding are evidence of high-quality workmanship. The screws supplied fit exactly and enable easy assembly

The HAUSPROFI titanium replacement blades really impressed us in the test gel practical test. In the sharpening test, they showed a clean cut when cutting through paper, with only minimal fraying – a clear indication of a precisely ground cutting edge. They also impressed in the material test with their high resistance: neither the magnetic test nor the scratch test showed any significant weaknesses. The titanium coating proved to be abrasion-resistant and of high surface quality.

When fitted to the robotic lawnmower, the blades were largely a perfect fit and worked reliably during operation. However, it was noticeable that the screws supplied did not fit perfectly on all devices – depending on the model, some readjustment or the use of existing original screws was necessary. In the subsequent test run, the blades nevertheless worked quietly and vibration-free, which speaks in favour of a good balance. The noise level was also inconspicuous.

Changing the blades was easy with a standard screwdriver – the instructions are clear and easy to understand and the blades fit securely after changing. Overall, the set offers a very solid performance, with slight compromises in terms of screw compatibility.
