When my gas-powered weed trimmer finally died last spring—after years of frustrating pull-cord starts, fume exposure, and constant maintenance—I knew I wanted cordless convenience but worried about battery power compromising performance. After researching dozens of options and testing three different models, I settled on the WeGofly string trimmer 14-inch cordless with dual 21V 6.0Ah batteries. Six months and countless yard projects later, this $120-150 investment has proven itself the smartest lawn tool upgrade I’ve made.
If you’re searching for a cordless weed wacker that truly replaces gas-powered tools without sacrificing cutting power, runtime, or versatility, this WeGofly 4-in-1 electric weed eater deserves attention. After half a season maintaining my 1/4-acre suburban yard, here’s my honest assessment of whether this battery powered weed wacker lives up to its revolutionary multi-function promises.
What Makes the WeGofly String Trimmer Different from Budget Cordless Options?
Unlike cheap battery trimmers using weak motors and single small batteries (dying mid-job), the WeGofly string trimmer features a 21,000 RPM brushless motor with DUAL 21V 6.0Ah high-capacity batteries. According to lawn tool performance research from Consumer Reports, brushless motors deliver 30-50% more power and 2x longer lifespan than brushed alternatives while maintaining consistent torque under load.
The 4-in-1 lawn edger and trimmer combo addresses comprehensive yard maintenance challenges: trimming grass edges, edging walkways/driveways, mowing small lawn areas, and cutting thick brush—all with one tool, eliminating the need for separate equipment purchases.
Most trimmers do one job. The WeGofly 14 inch string trimmer transforms between four distinct modes:
Mode 1 – String Trimmer:
- Auto-feed rope spool (no manual line advancement)
- 14-inch cutting diameter
- Perfect for grass trimming and light weed control
Mode 2 – Wheeled Edger:
- 90° rotatable head converts to vertical position
- Adjustable wheels create straight lines
- Ideal for sidewalk/driveway edging
Mode 3 – Mini Lawn Mower:
- Metal blade attachment (included)
- Auxiliary bracket creates push-mower function
- Handles medium-sized lawn sections
Mode 4 – Brush Cutter:
- Heavy-duty saw blade attachment (included)
- Cuts thick weeds, saplings, and brush
- Tackles overgrown areas traditional trimmers can’t
This comprehensive capability means I haven’t needed my gas push-mower for small lawn touchups—the WeGofly handles everything.
My 6-Month Experience with the WeGofly String Trimmer
First Charge and Initial Testing
When my WeGofly cordless weed wacker arrived, I followed the included instructions: charge both batteries fully before first use. The dual-battery system provides smart continuity—while one battery depletes, swap to the second (fully charged) without interrupting work. The included fast charger took approximately 2 hours to fully charge each 6.0Ah battery.
My first test involved trimming my entire property perimeter (approximately 150 linear feet) with thick spring growth. Using the string trimmer mode at full power, I completed the job on a single battery charge with 30% capacity remaining. This impressed me—my previous battery trimmer would’ve required 2-3 battery swaps for the same job.
Week Three: Testing All Four Modes
By week three, I’d tested every function:
String Trimmer Performance: The auto-feed rope spool worked flawlessly—no stopping to manually advance line. The 14-inch cutting width covered ground quickly, and the 21,000 RPM motor maintained consistent speed even in thick grass.
Edger Capability: Rotating the head 90° and attaching wheels created surprisingly professional edging results. The adjustable wheels kept consistent depth, producing straight, clean lines along my driveway.
Mini Mower Function: Installing the metal blade and auxiliary bracket transformed the tool into a small push-mower. I used this for tight areas my regular mower couldn’t access—around trees, fence posts, garden beds.
Brush Cutter Power: The saw blade attachment tackled overgrown areas behind my shed that I’d ignored for years. It cut through 1-inch diameter saplings and thick brush that would’ve jammed traditional trimmers.
After maintaining my yard through an entire growing season (April-September), here’s the unfiltered truth:
What’s Exceeded Expectations:
- Dual 6.0Ah batteries provide 45-60 minutes runtime EACH (90-120 total)
- Brushless motor maintains power consistently (no fade under load)
- Auto-feed string spool has never jammed or required manual adjustment
- All four modes function as promised—not gimmicky marketing
- Lightweight design (8-9 lbs) prevents fatigue during extended use
What Required Adjustment:
- Learning optimal trigger control (full throttle unnecessary for light work)
- Replacing string line after approximately 2 months heavy use
- Metal blade dulled after cutting thick brush (expected, easily sharpened)
- Auxiliary bracket takes 2-3 minutes to attach/remove
What Failed: Nothing. Six months in, the WeGofly string trimmer functions perfectly. This reliability surprised me given the $120-150 price point.
The Dual 21V 6.0Ah Battery System: Game-Changing Runtime
The battery system deserves special attention. Each 21V 6.0Ah battery provides approximately 45-60 minutes of runtime depending on workload intensity. According to battery technology research from Popular Mechanics, 6.0Ah capacity represents “professional-grade” for cordless lawn tools—most consumer models include 2.0-4.0Ah batteries.
Real-World Runtime Breakdown:
- Light trimming (minimal throttle): 55-60 minutes per battery
- Normal mixed use (trimming + edging): 45-50 minutes per battery
- Heavy brush cutting (full throttle): 35-40 minutes per battery
With TWO batteries included, I’ve never run out of power mid-job. One battery always charges while using the second. The digital display on the handle shows remaining battery percentage—helpful for planning workflow.
The batteries are compatible with all WeGofly 21V tools, meaning if I purchase their leaf blower or hedge trimmer later, I can share batteries across the platform.
Who Should Buy This WeGofly String Trimmer?
Based on six months of comprehensive yard maintenance, this 4-in-1 cordless trimmer excels for:
Suburban Homeowners (1/8 to 1/2 Acre) Perfect yard size for battery-powered tools. My 1/4-acre property requires one full battery charge for complete perimeter trimming plus edging—the second battery provides ample backup.
Anyone Tired of Gas-Powered Hassles If you’re sick of pull-cord starting frustrations, gas/oil mixing, fume exposure, winterization requirements, and constant maintenance, battery power transforms the experience. Push-button starting, zero emissions, minimal maintenance.
Multi-Property Owners or Landlords The 4-in-1 versatility means carrying one tool handles trimming, edging, and brush clearing at multiple rental properties. The included storage bag organizes everything compactly.
Elderly or Physically Limited Users At 8-9 pounds (significantly lighter than 15-20 lb gas trimmers), this reduces fatigue. The adjustable handle and auxiliary bracket further minimize physical strain.
Environmentally Conscious Yard Maintainers According to the EPA, one hour of gas-powered lawn equipment operation produces emissions equivalent to driving a car 100+ miles. Electric tools eliminate this pollution entirely.
Real Talk: Limitations and Realistic Expectations
Honest reviews require acknowledging what this WeGofly cordless weed wacker isn’t:
Not for Large Multi-Acre Properties If you maintain 2+ acres regularly, professional-grade gas or larger electric systems make more sense. Battery runtime and cutting width suit typical suburban yards, not sprawling properties.
Battery Replacement Cost Eventually (3-5 years typical), batteries will degrade requiring replacement. Budget approximately $50-70 per battery. However, this remains cheaper than annual gas-trimmer maintenance.
Not Commercial-Grade Durability Landscaping professionals using tools 40+ hours weekly need commercial equipment. The WeGofly excels for homeowners using it 2-4 hours weekly.
String Line Replacement Needed The auto-feed spool requires occasional string line refills (approximately every 2-3 months for average use). Replacement line costs $10-15.
Heavier Than Gas Trimmers Initially The dual batteries add weight compared to an empty gas trimmer. However, once you fill a gas tank (adding 2-3 lbs), weight equalizes.
Maintenance and Long-Term Care
After six months, here’s my maintenance routine for the electric weed eater cordless:
After Each Use:
- Remove grass clippings from motor housing
- Wipe down with damp cloth
- Check string line level (replace if under 2″)
- Store batteries at 40-60% charge if not using soon
Monthly:
- Clean battery contacts with dry cloth
- Inspect metal blade for damage/dullness
- Tighten any loose screws or components
- Check auxiliary bracket connections
Seasonally:
- Sharpen or replace metal blades
- Replace string line spool
- Deep clean entire tool
- Store indoors during winter (remove batteries)
This minimal maintenance keeps the WeGofly battery powered weed wacker performing like new. The brushless motor requires zero maintenance—a major advantage over gas engines.
How the WeGofly String Trimmer Compares
WeGofly vs. Black+Decker LST136W ($90-110)
Black+Decker’s popular model costs less but includes only ONE 2.0Ah battery (vs TWO 6.0Ah WeGofly batteries). The runtime difference is dramatic: Black+Decker provides 15-20 minutes per charge, requiring multiple recharges for typical yards. WeGofly’s 90-120 minute total runtime eliminates this frustration.
WeGofly vs. EGO Power+ ST1521S ($200-250)
EGO offers premium build quality and brand reputation but costs nearly double. For most homeowners, WeGofly delivers 80% of EGO’s performance at 50% of the cost—better value unless brand names matter significantly.
WeGofly vs. Gas-Powered Echo or Stihl ($250-400+)
Professional gas trimmers provide unlimited runtime and maximum power but require:
- Gas/oil mixture preparation
- Regular maintenance (spark plugs, air filters, fuel lines)
- Pull-cord starting (increasingly difficult as machines age)
- Fume exposure and noise pollution
- Higher upfront cost
The WeGofly trades unlimited runtime for push-button convenience, zero emissions, and minimal maintenance—a worthy trade for typical homeowners.
The Verdict: Outstanding Value for Modern Yard Maintenance
After six months replacing my gas trimmer with this WeGofly string trimmer, I have zero regrets. The combination of genuine 4-in-1 versatility, dual high-capacity batteries, and brushless motor power delivers gas-trimmer performance with electric convenience.
Buy this WeGofly 4-in-1 string trimmer if:
- You maintain 1/8 to 1/2 acre suburban/residential properties
