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.

Lehmann
Haddo industrial vacuum cleaner

Product description of the manufacturer

The Lehmann Haddo industrial vacuum cleaner 2000W is a versatile cleaning appliance designed for use in workshops, construction sites and households. With an output of 2000 watts, it promises a high suction power that is suitable for both dry dirt and liquids. The robust stainless steel housing and extensive accessories, including various nozzles and filters, are designed to enable efficient cleaning. A particularly noteworthy advantage is the strong suction power, which is rated positively by many users. However, there are also points of criticism regarding the noise level, as the vacuum cleaner is perceived as relatively loud during operation.

  • High suction power
  • Robust stainless steel housing
  • Versatile use (dry and wet vacuuming)
  • Extensive range of accessories
  • High volume during operation

The design of the Lehmann Haddo is functional and designed for industrial use. The stainless steel housing not only has a high-quality appearance, but also protects against corrosion and mechanical damage. The overall workmanship is solid, all parts fit tightly and there are no sharp edges or visible defects.The castors on the base make it easy to transport, and the carrying handle is ergonomic and makes it easier to lift the appliance. The cable length of 3.5 m is long enough to ensure flexible use without the need for frequent unplugging.

In the test, the Lehmann Haddo industrial vacuum cleaner impressed with its excellent suction power on carpets, hardwood and tiles. Even fine dust particles were removed efficiently. Removing and emptying the container was straightforward, as the dust container is easily accessible and can be emptied without creating a lot of dust. Re-insertion also went smoothly, as the container locks securely into place.

The stability proved to be another plus point: the device did not tip over even on inclined surfaces, and the robust castors ensured safe handling. The carrying handle was comfortable to hold and remained stable even under load. The only point of criticism is the high volume, which is above average and could be annoying under certain circumstances.

Overall, the vacuum cleaner lives up to its advertising promises and impresses with its powerful suction power, high stability and easy handling.
