After you have used a cleaning brush for a while, the bristles of the brush usually become very weak. Some can even become deformed and bent, making it difficult to use the brush to achieve the excellent cleaning results you want. When this happens, you usually need to get a new brush.
However, this brush has removable brush heads , which ensure that you can easily swap out an old brush head for a new one. This means that you don't have to buy a completely new brush, just replace the brush head. The removable brush head also means that you can remove the brush part and use it directly for scrubbing, especially if the stain is quite hard and you don't want to risk the brush bar breaking. How practical!
