There are several things to consider when choosing a blower-vac. Should you buy a petrol or electric power blower? Is a simple blower sufficient or would a combination blower/vacuum clean up the yard more efficiently? Does your yard size and your physical condition warrant a handheld leaf blower, a backpack blower, or a walk-behind blower? And, last but not least, how much are you willing to spend on a leaf blower?
Petrol powered leaf blowers are more powerful and do not require a cord, which can restrict your movement. Electrical blowers are usually less expensive. Others have rechargeable batteries. These units are the least powerful and are best for small yards and surfaces such as driveways.
