Brushless blowers are designed to last longer and do not require maintenance because they use a non-contact digital technology to create motion. Brushed blowers do the same thing (move air) but require regular replacement of brushes, which are used to generate the motion. The brushes wear down over time because they come into physical contact with the spinning part of the blower. Brushed blowers are relatively inexpensive, but you will have to replace brushes and even the blower themselves as they wear out. In contrast, brushless blowers have been known to last over 10 years.
