Sun Joe MJ403E Mow Joe 17-Inch 13-Amp El vs Goplus Lawn Mower, 13 Inch 2-in-1 Electr

Quick Verdict

For most homeowners with a small to medium yard, the Sun Joe MJ403E is the stronger choice. It offers a wider cutting deck, more power, and a mulching function that the Goplus lacks. However, if you have a very small lawn, a tight budget, or need a lighter machine for easy maneuvering, the Goplus is a capable, lower-cost alternative.

Side-by-Side

Both mowers share the same motor amperage, but the Sun Joe’s wider deck covers more ground per pass. The Goplus’s narrower 13-inch cut is better suited for tight spaces and smaller lawns.

Where Sun Joe Wins

• Wider cutting deck (17 inches) – Cuts about 30% more grass per pass than the Goplus. This means fewer passes and less mowing time on a typical lawn.
• Mulching capability – The Sun Joe is specifically designed as a mower/mulcher, which lets you leave finely chopped clippings on the lawn to return nutrients to the soil. The Goplus does not offer a dedicated mulching function.
• Higher ratings volume – With 1,223 reviews compared to the Goplus’s 613, the Sun Joe has a larger base of user feedback, indicating broader market trust and longer-term reliability.
• Better for medium lawns – Its 17-inch cut and 13-amp motor handle grass up to about 1/4 acre without bogging down, while the Goplus is best for much smaller areas.

Where Goplus Wins

• Lower price ($129.99) – Costs $100 less than the Sun Joe. If you’re on a strict budget or only need a mower for a tiny yard, the Goplus saves significant money.
• Lighter and more compact – The 13-inch cutting width and smaller overall frame make it easier to store in tight spaces and maneuver around flower beds, garden edges, and narrow pathways.
• 2-in-1 design – Includes a grass collection bag and side discharge. While it lacks mulching, the bagging option is effective for keeping clippings off the lawn, which some users prefer.
• Sufficient for very small lawns – For yards under 1/8 acre (e.g., a small front lawn or a postage-stamp backyard), the Goplus’s narrower deck is not a disadvantage and the lower price becomes the deciding factor.

Which Should You Buy

Choose the Sun Joe MJ403E if:

• Your lawn is between 1/8 and 1/4 acre.
• You want to mulch clippings for healthier grass.
• You prefer fewer passes and faster mowing.
• You value a mower with a larger user base and proven track record.

Choose the Goplus if:

• Your yard is very small (under 1/8 acre).
• Your budget is tight and you want to spend under $150.
• You need a lightweight mower for frequent lifting or storage in a small shed.
• You prefer bagging over mulching and don’t need a dedicated mulching function.

In short: the Sun Joe is the better overall mower for most people, but the Goplus is a smart buy for the smallest lawns and tightest budgets.
