    Check price on AmazonAffiliate link

A good cordless strimmer does two jobs: trimming grass that the mower cannot reach and cutting a clean vertical edge along paths and borders. For edging, look for a head that turns or a guide wheel. For tougher growth, look at line diameter and swath, or a brush cutter blade. Line feed matters more than it sounds, because tapping and pulling line by hand slows every job. This guide compares cordless strimmers on cutting swath, line size and feed type, edging features and what battery comes in the box, using only the facts each listing states. Wear eye protection and follow the safety kit list in your manual whichever model you choose.
