There are several innvations that has been introduced together with the Ergorapido over the years. One of the most important ones is Brush Roll Clean Technology.
Brush Roll Clean allows you by the press of a button on the nozzle to clean the motorized brush from all tangled hair. This allows you to continously have the best cleaning performance, without any need to use scissors and deal with all the things that got stuck.
This is achieved by having a knife going in and automatically cutting of the tangled hair, when you press the button. It is really an ingenious solution, that has been patented, and trademarked.
