Miele bagless cylinder vacuum cleaner takes top spot in Stiftung Warentest consumer test

Gütersloh, February 5, 2025 No. 003/2025
  • Boost CX1 Allergy secures victory with a score of 2.1

  • Top ratings in five of the six test categories

The Boost CX1 Allergy bagless cylinder vacuum cleaner from Miele is the test winner in the current online vacuum cleaner test conducted by German consumer watchdog Stiftung Warentest (StiWa) and has received the overall score of GOOD (2.1). With this victory, a Miele vacuum cleaner has once again taken the top step on the podium. Two bagless cylinder vacuum cleaners were tested this time round. The results were added to the existing test results from 09/2024 as part of StiWa’s continuous testing and compared against these. The details can be consulted on the Stiftung Warentest website at www.test.de under the “Staubsauger im Test” section (in German).

The Boost CX1 Allergy won over the testers most notably in the durability (1.1), safety (1.0) and pollutants (1.0) categories, consistently receiving the VERY GOOD rating. In the suction (2.0) and environmental properties (1.9) categories, the testers awarded the appliance the rating GOOD. The Boost also came out on top in the handling category (2.7), which was unmatched by competitors, achieving a rating of SATISFACTORY.

The Boost CX1 is Miele’s smallest bagless vacuum cleaner. Particularly eye-catching are the large side wheels which make the vacuum cleaner highly agile and keep it on track (TrackDrive). As a result, the appliance can be manoeuvred precisely and remains nimble and able to turn on the spot. This makes it ideal for small or narrow spaces, as collisions with furniture are prevented. The appliance even stands securely on staircases and cannot roll off to the side.

Compact design meets powerful performance

Whether parquet, laminate or carpet – the powerful Boost CX1 is a high performer on any floor, so dust doesn’t stand a chance. With an air flow of over 100 km/h, the vacuum cleaner reliably picks up both coarse soiling and the tiniest dust particles. The Hygiene Air filter that is integrated in the entry-level model ensures exceptional filtration of even the finest particles (filter frame made from 100 % recycled material). The HEPA AirClean filter, which is installed in the Allergy, Cat & Dog and Parquet models, filters more than 99.95 %* of particles, making it the ideal solution for people who are allergic to house dust.

With its operating radius of 10 metres, the Boost offers great flexibility and freedom when vacuuming. If necessary, the floorhead and suction tube can be stowed on the side of the appliance, providing a practical feature when users want to take a break during cleaning. Weighing 7.75 kilograms in total, the Boost is easy to carry from one room to another. The 1 l dust container can be conveniently pulled up and out and emptied at the press of a button to ensure cleanliness and hygiene.
