Verdict

The Bomann CB 947 is a compact and lightweight corded handheld vacuum cleaner weighing approximately 1.45 kg and measuring 24 x 12 x 15 cm. Operating on a 230V, 50Hz power supply, it features a powerful 700W motor and a 0.3-liter dust capacity tank equipped with a washable permanent dust filter. Its main characteristics include an extensive 6-meter power cord and a vertical storage design for space-saving convenience. Users benefit from continuous, fade-free suction ideal for cleaning furniture, upholstery, cars, and keyboards, supported by included accessories like a flexible suction hose, a crevice nozzle, small and large brushes, and a shoulder strap for comfortable transport. However, prominent drawbacks include its high operating noise level during use and the lack of cordless portability since it relies entirely on a mains power outlet.
