After studying various test we opted for the latest technology from Bosch decided that low volume, no filters, high energy efficiency, etc. The vacuum cleaner keeps all these promises, but suck at the Turbo Universal brush, the most important part for, you well saved. With the small wheels the brush can barely move on a rug / carpet already at rest. If you switch the vacuum cleaner (lowest power) sticks the nozzle formally on the rug / carpet. A reasonable sucking is impossible. Who in his apartment has a high proportion of carpeting / rugs, should steer clear of this model.
