For Rowenta AC 9258 is to say in comparison with the similar oa Philips vacuum cleaner that the suction power is higher. The handling is similar. The design seems to be a "tick" to be more practical and more robust.
However, a significant drawback is the Rowenta AC 9258 compared to the OA Philips vacuum cleaners: He lacks a charging cradle, you may also be mounted on the wall and in the vacuum cleaner can be loaded and stored simultaneously. So you can make the sucker only to the motor housing, connect the plug of the cable connected socket power supply and find an area for parking of very expensive piece.
For a deduction of one point!
