Frequently asked questions
How does an automatic cordless lawn edger work?
An automatic cordless lawn edger uses a battery-powered motor to spin a cutting line or blade. The ‘automatic’ aspect refers to the line feed system that automatically advances the cutting line as it wears, so you don’t have to stop to manually pull more line. Some robotic models navigate on their own along a boundary wire.
What is the difference between an edger and a trimmer?
An edger is designed to cut a clean vertical edge along sidewalks, driveways, and flower beds. A trimmer is used to cut grass in areas a mower cannot reach, such as around trees and fences. Some tools combine both functions, but dedicated edgers often provide a sharper, more precise cut.
Can a robotic edger handle slopes?
Most robotic edgers are designed for flat or gently sloping areas. Steep slopes may cause the robot to lose traction or the cutting head to miss the edge. Check the specifications for maximum slope percentage. The Worx Landroid, for example, can handle slopes up to 15 degrees, but individual results vary.
How long does the battery last on a cordless edger?
Battery life varies by model and battery capacity. On a full charge, handheld edgers typically run 20 to 45 minutes, depending on the load and grass thickness. Robotic edgers can run up to 60 minutes or more before returning to the charging base. Using a higher amp-hour battery extends runtime.
Do I need to set up boundary wires for a robotic edger?
Yes, most robotic edgers require you to install a boundary wire around the area you want them to edge. This wire emits a signal that the robot follows. The installation takes some time, but it is a one-time setup. Some models use GPS or camera-based navigation, but they are less common for edging.
Can I use a regular trimmer line in an automatic edger?
Automatic edgers often use proprietary spools or specific line diameters. It is best to use the line recommended by the manufacturer to ensure proper feeding and cutting performance. Using the wrong line can cause jams or poor results.
Are automatic edgers louder than gas-powered ones?
No, battery-powered edgers are significantly quieter than gas models. They produce about 60 to 70 dB of noise, which is comparable to a normal conversation. This makes them suitable for use in noise-sensitive neighborhoods.
How often should I edge my lawn?
During the growing season, edging every one to two weeks helps maintain a sharp look. Robotic edgers can run more frequently if set on a schedule. Handheld edging is typically done weekly or biweekly, depending on how fast your grass grows.
Can I edge with a robotic mower instead?
Robotic mowers are designed to mow the entire lawn, but they may not have a dedicated edging function. Some models have a ‘cut to edge’ feature that trims grass that overhangs the perimeter, but they do not create a deep, clean edge. A dedicated edger is better for that purpose.
What safety features should I look for?
Look for edgers with a safety switch that stops the blade or line when you release the handle. Some models have a guard that prevents debris from flying. Always wear safety glasses and long pants when edging. Robotic edgers have sensors to detect obstacles and lift-off, which stop the blades.
The bottom line
For most homeowners, the Worx Landroid Robotic Edge Trimmer is the best choice if you want true automation and have a defined edge to maintain. It saves the most time and effort. If you prefer a handheld tool for more control and versatility, the DEWALT 20V MAX XR Cordless Edger offers the best power and build quality. For budget buyers, the Greenworks 24V Cordless Edger provides solid performance at a lower cost. Choose based on your willingness to set up a boundary wire and your need for automation.
