With gas powered mulchers, you probably need to spend a bit time maintaining and winterizing an engine. In general, please do not leave the gas in the tank for a long time.

Most of the electric ones are with power cord. Obviously, your yard can not be too big unless there are power outlets everywhere, which is not that practical. There are few electric leaf vacuum mulchers that have lithium battery. Now, you can carry them around in your yard without the restraint of power cord. However, those units are usually less powerful than the corded ones. Whether buy gas or electric ones, you have decide which suits you best in your situation.

CFM stands for Cubic Feet Per Minute of airflow. MPH is for miles per hour. These two number describe how powerful your vacuum or blower is. Apparently, the higher those numbers are, the more power your unit is.
