Reviews last updated: July 2026 · How we calculate this

What we like about Bomann CB 947

  • Powerful and consistent suction power due to corded operation
  • Generous 6-meter long power cord provides a large cleaning radius
  • Versatile range of accessories including crevice nozzle, brushes, and a shoulder strap
  • Compact, lightweight design that makes it highly portable and easy to store
  • Bagless design featuring a permanent cloth dust filter that is easy to clean
  • Excellent value for money and highly affordable

What we don't like about Bomann CB 947

  • Perceived by many users as being quite noisy and loud during operation
  • The unit tends to get warm or heat up quickly during extended use
  • Relatively small dust container capacity which requires frequent emptying
  • Not suitable for large-scale cleaning tasks and restricted to spot or quick clean-ups

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.
