- You prefer automatic line feed that advances the trimmer line as needed.
- You want higher voltage power for faster cutting and stronger sweeping.

Voltage and Power System Comparison
Voltage and System
The BLACK+DECKER 20V MAX String Trimmer and Edger operates on a 20V MAX lithium battery system. This platform is designed for lighter, more precise tasks like trimming edges and detailing around obstacles. The BLACK+DECKER 40V Max Cordless Sweeper and String Trimmer Combo runs on a higher voltage 40V MAX system. This increased voltage provides more raw power for the sweeper attachment, which requires significant airflow to clear debris. You get a battery and charger included with both units. The 40V system generally offers more torque for tougher jobs, while the 20V system prioritizes maneuverability and extended runtime for smaller yards.
Cutting Width
The BLACK+DECKER 20V MAX String Trimmer and Edger features a 12-inch cutting width. This swath allows you to clear weeds and grass efficiently in a single pass. The BLACK+DECKER 40V Max Cordless Sweeper and String Trimmer Combo does not list a specific cutting width in its provided specifications. However, it is a combo unit that includes a sweeper attachment. The sweeper component focuses on clearing hard surfaces rather than cutting grass. If your primary need is a dedicated trimmer with a known cutting path, the 20V model gives you a clear 12-inch metric. The 40V model trades a specified cutting width for the added versatility of a sweeper.
Line Feed Mechanism
Line feed systems determine how you replace or advance the trimmer string. The BLACK+DECKER 20V MAX String Trimmer and Edger uses an EASYFEED push-button system. You advance the line with the push of a button, eliminating the need to bump the head on the ground. This offers precise control and reduces wear on the spool. The BLACK+DECKER 40V Max Cordless Sweeper and String Trimmer Combo utilizes an Automatic Feed Spool (AFS). This system automatically feeds trimmer line as needed during operation. You do not need to stop or press a button. AFS is convenient for continuous trimming, while the push-button method offers more deliberate control over line length.
Weight and Portability
Weight affects how easy a tool is to carry and maneuver. The BLACK+DECKER 20V MAX String Trimmer and Edger weighs 6.3 pounds. This lighter weight makes it easier to hold for extended periods and maneuver around tight spaces. The BLACK+DECKER 40V Max Cordless Sweeper and String Trimmer Combo weighs 11 pounds. This significant weight difference is due to the additional sweeper attachment and the more powerful 40V motor assembly. The heavier unit may feel more substantial and stable during heavy use, but it will cause more fatigue over time. If you prefer a lighter tool for quick touch-ups, the 20V model is the better choice.
Sweeper Capability
The BLACK+DECKER 20V MAX String Trimmer and Edger is a dedicated trimming and edging tool. It does not include a sweeper attachment in its base specifications. The BLACK+DECKER 40V Max Cordless Sweeper and String Trimmer Combo includes a LSW40 40V MAX Sweeper. This attachment generates wind speeds of up to 130 MPH. It is designed to easily clear debris from hard surfaces like driveways and patios. If you need to clear leaves, grass clippings, or dirt from paved areas, the 40V combo unit provides this functionality. The 20V model is strictly for cutting vegetation and does not offer sweeping capabilities.
