Product details

The Unlimited 9 cordless vacuum cleaner offers a comprehensive cleaning solution for various floor types. Equipped with unique MicroClean Technology, it not only removes visible dust but also microscopic particles that the eye cannot detect. The innovative MicroClean nozzle ensures thorough cleaning and is particularly effective on all surfaces. The Easy Empty dust container allows for hygienic disposal, which is required up to 50% less often, while the HEPA filter system provides clean exhaust air by filtering over 99.99% of particles. The TurboSpin motor, manufactured in Germany, delivers high performance and is backed by a 10-year motor warranty. With a long runtime and the ability to swap out the battery, this vacuum cleaner is ideal for flexible and efficient cleaning.

  • MicroClean Technology for thorough cleaning beyond the visible
