Our take
The Sun Joe MJ402E-RM is a remanufactured-model, 16-inch corded mower documented for private residential use on small lawns and gardens. Its exact manual lists a 12 A, 120 V motor, six height positions from 1.2 to 3.15 inches, a 9.3-gallon bag, and a 30.4-pound weight. A corded setup avoids battery-and-charger bundle questions but requires a suitable outlet and extension cord across the whole route. Snow Joe’s manual does not establish side discharge or mulching for this model. This is a documentation-based review, not a cutting test.
A buyer with a small lawn, reachable outdoor power, and a preference for a corded mower with a collection bag..
It is not a good fit if the yard has no practical cord route, if cordless operation is essential, or if side discharge or mulching must be confirmed. The current condition and package of a renewed seller offer still need checking.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The maker’s exact MJ402E-RM manual documents a 16-inch deck and 12 A, 120 V corded power.
- Six height positions span 1.2 to 3.15 inches, and the handle can be set to three documented heights.
- The included grass collection bag is rated at 9.3 gallons, and the mower’s manual lists a 30.4-pound weight.
What to weigh up
- The cord and a suitable outlet must reach every part of the mowing route; the manual specifies extension-cord sizing guidance.
- The exact manual does not confirm mulching or a side-discharge mode, so those needs remain unsupported.
- This is a remanufactured-model listing, and the current seller’s condition and package contents are not independently verified.

Full review: how the features affect your choice
What the features mean for you
A compact deck for small residential lawns
Snow Joe describes the MJ402E-RM for private residential use on small lawns and gardens, and its manual lists a 16-inch deck with a 15-inch steel blade. The mower weighs 30.4 pounds in the technical data. Those documented dimensions place it among the narrower options in this comparison, where route access and a compact working width can matter more than minimizing passes. The maker does not claim a specific yard size or mowing time, so the small-lawn description should not be converted into a square-foot promise.
Plan for the cord before choosing it
The exact manual rates the mower at 120 V and 12 A and includes extension-cord guidance. In use, the operator must route a suitable cord from a compatible outlet without allowing it to enter the blade path. That makes the electrical setup an everyday constraint that a cordless mower does not share, even though corded power avoids battery charging and kit compatibility. The documentation offers no battery platform, maximum runtime, or per-charge area figure because this model runs from an outlet while connected to its cord.
A bag is documented; other clipping modes are not
The manual lists a grass collection bag with a capacity of 9.3 gallons, or 35.2 liters, and includes that bag in its carton contents. For a common comparison unit, the profile converts that published volume to approximately one U.S. dry bushel. The manual describes the rear collection setup but does not identify a mulching plug or side-discharge chute for MJ402E-RM. Those modes stay unconfirmed in the profile instead of being borrowed from another Sun Joe model or assumed from a similar deck.
Six cut heights and a three-position handle
The manual gives six cutting-height positions from 1.2 to 3.15 inches. It also shows three handle-height positions, listed at 37.2, 40.35, and 44.69 inches. That makes the setup more adjustable than a single fixed handle position, although those dimensions do not predict comfort for every operator. The mower’s height range falls short of a four-inch maximum, and its lowest setting is above one inch. Follow the manufacturer’s instructions for height changes with the mower unplugged and the blade stopped.
Check the renewed offer and storage requirements
The RM suffix is covered by a Snow Joe remanufactured-model manual, but that document cannot confirm the condition or contents of a particular current seller offer. Compare the listing’s exact model code and confirm the mower, grass bag, guards, and manual before buying. Snow Joe directs owners to store the mower indoors in a dry, clean, cool area and to disconnect its power supply first. The manual does not describe a folding-storage configuration, so compact storage should not be assumed from the mower’s relatively light listed weight.

Before you buy
Does MJ402E-RM run on a battery?
No. Snow Joe’s manual specifies a 120 V, 12 A corded electric mower. It requires a suitable power source and extension cord; it has no documented battery runtime.
Does it mulch or discharge clippings to the side?
The exact MJ402E-RM manual documents a collection bag but does not confirm either mulching or side discharge. The profile leaves those features unknown.
What cut-height range does the manual list?
The mower has six positions from 1.2 to 3.15 inches. Snow Joe also documents three handle-height settings; neither range is a claim about the right cut for a particular lawn.
