Key Specs: 20V vs 40V WORX Kits
Voltage and Power
The WORX WG931 operates on a 20V system, while the WP935 uses a 40V platform. Higher voltage generally translates to more torque and sustained power under load. The 40V WP935 is designed to handle thicker grass and denser weeds with less strain on the motor. You will notice the difference when cutting through wet or heavy vegetation. The 20V model is sufficient for standard lawn edges and light trimming tasks. However, if your yard has overgrown areas or tough weeds, the extra power from the 40V system provides a clearer advantage. It ensures the tool does not bog down during extended use.
Cutting Swath Width
Cutting width determines how much area you cover with each pass. The WP935 features a 15-inch cutting swath, which is wider than the 12-inch width of the WG931. This three-inch difference may seem small, but it adds up over time. A wider swath means fewer passes to clear the same amount of grass or weeds. You will finish trimming borders and edges faster with the 40V model. The 12-inch width on the WG931 is still adequate for most residential yards, but it requires more time to cover large areas. If you have a medium to large lawn, the wider cut is more efficient.
Shaft Construction and Weight
Build quality affects how the tool feels in your hands. The WP935 uses a carbon fiber shaft, which is both lightweight and rigid. This material helps reduce overall weight and improves balance during long trimming sessions. The WG931 is a 3-in-1 kit that includes a hedge trimmer and blower, adding complexity and weight. The WG931 weighs 17.7 pounds, while the WP935 weighs 20 pounds. However, the carbon fiber shaft in the WP935 likely offers better vibration dampening and durability. For pure trimming tasks, the specialized shaft in the 40V model provides better control and less fatigue.
Blower Air Volume
Both kits include a blower attachment, but their performance differs significantly. The WG931 includes a 360 CFM blower based on a turbine design. The WP935 features a 530 CFM blower, which moves more air volume. Higher CFM means the blower can move heavier debris like wet leaves and clippings more effectively. The WP935 blower also operates at a quieter 57 dB, making it more pleasant to use around neighbors or family. The 360 CFM output on the WG931 is decent for light dust and dry leaves, but the 530 CFM output on the 40V model is superior for heavy yard cleanup tasks.
Tool Versatility and Bundle
The WG931 is a 3-in-1 kit that includes a hedge trimmer in addition to the trimmer and blower. This offers more versatility if you need to maintain hedges. The WP935 is a 2-in-1 kit focused on trimming and blowing. It includes a carbon fiber shaft and a dedicated blower, but no hedge trimmer. If you have bushes or hedges that need regular shaping, the WG931 saves you from buying a separate tool. However, if you only need to trim grass and clear debris, the WP935 is more specialized. The choice depends on whether you value hedge trimming capability over the higher power and wider cut of the 40V system.
Which WORX Weed Wacker Kit Fits You
Users needing extra hedge trimming capability
The WG931 kit includes a 22-inch hedge trimmer with dual-action blades. This allows you to maintain flat tops and catch every leaf and twig. The 20V system powers all three tools. You get a 12-inch cutting swath and a 360 CFM blower. This bundle covers trimming, edging, and hedge care in one package.
Those with medium to large yards
The WP925 features a 40V platform and a wider 15-inch cutting swath. This helps you cover more area for medium to large yards. The carbon fiber shaft reduces weight and improves control. The blower delivers 530 CFM of air volume. This setup is designed for cutting thick grass and handling heavy yard debris efficiently.
Buyers prioritizing quiet operation and balance
The 40V blower operates at only 57 dB, which is quieter than typical jet-engine designs. The carbon fiber shaft provides better balance during extended tasks. You get a 15-inch cutting width and 530 CFM airflow. The system allows combining 20V batteries for more power. This choice suits those who value lower noise levels and lighter handling.
