Quick verdict
A 5.2-pound 21V tool that swaps between string trimmer, edger, mini mower and light brush-cutter heads, with two 6.0 Ah batteries, a charger, spare blades and line in the box. It suits a small yard with soft weeds, bed edges and a strip of grass, and a user who wants something light. The caveat is the name: 21V and 13 inches is a light trimmer, not a brush cutter in the sense of a bladed gas machine.
Strengths
- Light at a stated 5.2 pounds
- Two 21V 6.0 Ah batteries and charger included

Who this tool is for
Not every yard needs a 56V trimmer or a gas brush cutter. A townhouse lot with a strip of grass, a few beds and a fence line is served by something light that can trim, edge and knock down soft weeds without a shoulder strap. The WeGofly 13-inch 4-in-1 is that kind of tool: a 21V brushless unit with a telescopic pole, swappable heads for trimming, edging, a mini-mower pass and light blade cutting, and two 6.0 Ah packs in the box. The brush-cutter label on the listing should be read loosely.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
WeGofly states a 13-inch cutting width, a 15000 RPM brushless motor with a steel gear set, a stated tool weight of 5.2 pounds, a telescopic pole, an adjustable cutting head, two 21V 6.0 Ah batteries with a matched charger, a set of replacement blades, trimmer line, a storage bag and installation tools. Assembly is described as tool-free. A 3-year warranty on the tool and 2 years on the batteries are stated, with online after-sales support. Blade material, line diameter and runtime are not given.
Cutting: trimmer, edger, mower and blade heads
At 13 inches and 21 volts this is a light trimmer, and that is how it performs best: weekly grass along a walk, around posts and under a bench. Tipped on its side it edges a bed. The mini-mower mode is a low pass over a small patch of lawn where a real mower will not fit. The blade head is for soft weeds, nettles and thin stems; owners of 21V multi-head tools consistently report that plastic or thin steel blades on this class of motor bounce off anything woody. WeGofly’s claim that the steel gears solve power problems and prevent burnout should be read as a durability claim, not a power claim; the motor is still a 21V unit.
Runtime and batteries
Two 21V 6.0 Ah packs is a lot of claimed capacity for a tool this size, and a second pack in the box means a small yard is finished without waiting on the charger. WeGofly does not publish a runtime figure, and stated capacities on 21V packs from lesser-known brands tend to be optimistic, so treat the figure as a relative measure rather than a promise. The packs are proprietary to WeGofly and do not fit other brands.
Build, handling and ergonomics
The 5.2-pound stated weight is the real selling point, and the telescopic pole and adjustable head let a short or tall user set a comfortable angle. The maker pitches it at women, seniors and beginners, which is fair for the effort involved. The build is plastic where a gas brush cutter is aluminum and steel; expect it to last as long as its batteries, which is the normal lifespan of unbranded 21V tools.
Living with it
Keep the spare blades and line in the storage bag and expect to use them; thin line and small blades are consumables. Charge the packs after each session and store them indoors. Register the stated warranty and keep the order record, since support for this kind of brand is handled through the seller rather than a dealer network.
Alternatives to Consider
The Worx 20V GT 3.0 is a comparable light trimmer and edger from a brand with a wide battery platform and established parts supply. The Ryobi 18V ONE+ 13-inch trimmer offers similar weight on a platform with hundreds of tools. If you actually need to cut brush, the Husqvarna 122RJ is a real gas brush cutter with a steel grass blade and a harness.
Verdict
Buy the WeGofly 13-inch 4-in-1 if your yard is small, your weeds are soft, you want the lightest tool that trims and edges, and two packs in the box appeals. Skip it if you searched for a brush cutter expecting to clear thick growth, or if you would rather pay a little more for a battery platform you can build on.

WeGofly 13-Inch 4-in-1 Cordless String Trimmer, Edger, Mower and Brush Cutter with Two 21V 6.0 Ah Batteries FAQs
Only in the light sense. A 21V motor on a 13-inch head will take down soft weeds and thin stems with its blades; woody brush and saplings need a gas or high-voltage battery machine with a steel blade and a harness.
The listing says a full set of replacement blades and trimmer line is included but does not state the blade material or line diameter. Tools of this class usually ship with small plastic blades and thin line.
WeGofly rates each pack at 6.0 Ah but does not publish a runtime. With two packs most small-yard sessions should finish on one charge, with the second in reserve.
The maker pitches it at women, seniors and beginners, and the 5.2-pound weight supports that. It is a tidy-up tool for edges and light weeds, not for an acre of rough ground.
