If you are shopping for a compact cordless mower and considering the Sun Joe Cordless Electric Push Lawn Mower with 11.9-Gal Bag, 15-Inch Cutting Width, 360W Motor – IONMAX 24V-CRLM15, the biggest question is not whether it looks convenient on paper. The real question is: does it actually deliver enough performance to justify the claims? We compared it side by side in our ework 40v cordless lawn mower review and against larger machines in our ego 42 cordless riding mower guide.

Quick Verdict
Verdict: A lightweight, low-maintenance mower for small, well-kept lawns — not a heavy-duty machine.
At around $259 with a 3.2-star average from roughly 140 reviews, the Sun Joe 24V-CRLM15 gets mixed reactions for a reason. Its genuinely strong points are its sub-30-pound weight, cordless freedom, tidy 11.9-gallon collection bag, and simple upkeep. Its weaknesses are just as clear: a modest 360W motor, a limited 0.6–2.0 inch cutting height range, and runtime that suits small lots rather than large properties.
Buy it if: you have a small yard, narrow side yards, or fenced garden paths and you mow weekly on already-maintained grass.
Skip it if: you expect gas-level torque, tall-grass capability, or more than 30–40 minutes of continuous cutting.

Product Overview
The Sun Joe IONMAX 24V-CRLM15 is a cordless electric push mower built for light to moderate lawn care. It pairs a 15-inch cutting deck with a 360-watt motor, a 5-blade RAZOREEL system, 4-position height adjustment, and an 11.9-gallon grass collection bag. The design goal is obvious from the spec sheet: keep it lightweight, portable, and far easier to maneuver and store than a gas mower.
The most appealing part of the design is its simplicity. There is no gas to store, no oil to change, no spark plugs to service, and no cord to drag across the lawn. For homeowners who want low-maintenance yard work and a quieter mowing experience, that combination is attractive. The compact footprint also makes it a natural fit for smaller lawns, townhouse yards, and narrow side passages where a wider deck would be awkward.
However, it is important to challenge the marketing language. A 360W motor is not especially powerful by mower standards, and the phrase “heavy-duty yard trimmer” overstates what this machine is. This is a lightweight maintenance mower, not a machine built for dense, overgrown, or rugged terrain. The advertised features are useful — but only when understood in context.
Pros
1. Lightweight and easy to maneuver
At just under 30 pounds, this mower is much easier to push, turn, and carry than gas-powered or larger battery models. That matters most for users with small yards, older users, or anyone who wants a mower that does not feel tiring after ten minutes. It is also simple to lift into a shed shelf or car trunk.
2. True cordless convenience
No extension cords, no fuel cans, no exhaust fumes. For quick weekly trims and small-to-medium lot maintenance, the cordless format is the main reason buyers choose a mower like this, and it delivers on that promise.
3. Compact 15-inch deck suits tight spaces
A 15-inch cutting width is small, but that is a benefit in constrained layouts. It navigates around fences, raised beds, and narrow pathways more easily than a 21-inch deck. If your yard is modest or segmented, this smaller footprint genuinely feels easier to control.
4. The 11.9-gallon bag keeps the lawn tidy
The included collection bag is a real convenience for homeowners who prefer to bag clippings rather than rake afterward. It holds a reasonable volume for a mower this size and gives the lawn a clean, finished look.
5. Adjustable cutting height
The 4-position manual height adjustment ranges from roughly 0.6 to 2.0 inches. That is not a wide range — you will not get a tall, lush 3.5-inch cut here — but it covers routine seasonal maintenance and lets you tune the finish for different grass conditions.
6. Very low maintenance
No oil changes, no spark plugs, no carburetor issues, no winter fuel stabilizer. Ownership is as simple as charge, mow, and occasionally clean the deck. For buyers who want a straightforward machine, this is a meaningful plus.
7. Well matched to regular, light mowing
This mower is designed for routine upkeep, not lawn rehabilitation. If your grass is already reasonably maintained and you mow weekly, its lighter build and simple functionality are enough to keep things neat with minimal effort. In that niche, it serves its purpose well.

Cons
1. The power claim may be overstated
A 360W motor simply does not produce the torque of a gas engine or a 40V+ battery platform. In thick, damp, or overgrown grass, expect the motor to strain, bog down, or require slower passes and multiple cuts. The “heavy-duty” labeling should be read as marketing, not a capability spec.
2. Limited battery runtime
Cordless mowers in this class typically deliver roughly 25–40 minutes of real-world cutting per charge, and dense grass reduces that further. If your lot is larger than about a quarter acre, plan on recharging mid-mow or buying a spare battery — which adds to the total cost.
3. Narrow cutting width means more passes
The same 15-inch deck that helps in tight spaces makes open lawn areas slower to finish. Mowing a medium yard with this machine simply takes longer than with a 20- or 21-inch mower.
4. Restrictive cutting height range
With a maximum cut around 2.0 inches, you cannot maintain taller grass types or let the lawn grow longer in hot, dry periods — a practice many extension services recommend for root health and drought resistance (see, e.g., turf guidance from University of Minnesota Extension). The fixed low-max range is a real limitation for lawn-health-minded owners.
5. Mixed owner feedback on durability
A 3.2-star average across about 140 reviews suggests inconsistent experiences. Common themes in reviews at this rating level include battery longevity concerns and plastic components that feel less robust than premium brands. Treat this as a budget-tier purchase with budget-tier longevity expectations.
6. Not suitable for rough or overgrown terrain
Uneven ground, tall weeds, and thick seasonal growth are outside this mower’s comfort zone. Buyers needing a machine for infrequent, heavy cutting should look at higher-voltage platforms instead.
Who Should Buy the Sun Joe 24V-CRLM15?
Good fit: owners of small, flat, regularly maintained lawns; townhouse and garden-path situations; anyone prioritizing light weight, quiet operation, and zero fuel maintenance.
Look elsewhere: buyers with lots over a quarter acre, thick or cool-season grass left to grow long, or expectations of gas-mower torque. In those cases, a higher-voltage platform from our 40V cordless mower review will serve you better.
FAQ
How long does the battery last on a single charge?
Expect roughly 25–40 minutes of cutting per full charge under normal conditions, less in thick or wet grass. That is enough for small urban and suburban lots but may require a recharge (or a spare battery) on anything larger than about a quarter acre.
Can the Sun Joe 24V-CRLM15 handle tall or wet grass?
Not well. The 360W motor will strain in tall, dense, or damp grass, and the 2.0-inch maximum cutting height limits how tall you can let your lawn get. Mow frequently and only when the grass is dry for the best results.
Does it come with the battery and charger?
Most retail configurations of the IONMAX 24V-CRLM15 include the 24V battery and charger, but bundles vary by seller. Confirm the included items in the specific listing before purchasing, since bare-tool versions do exist.
Is 15 inches enough cutting width?
For small, obstacle-filled yards, yes — the narrow deck is actually an advantage around beds, fences, and gates. For open lawns, it means more passes and longer mowing sessions. Match the deck size to your yard layout, not just its square footage.
How does it compare to a corded electric mower?
You give up unlimited runtime (a cord never dies) in exchange for freedom of movement and no cord-management hassle. For small yards where an outlet is nearby, a corded model can be cheaper and more consistent; for anything with obstacles or distance from power, the cordless format wins on convenience.
Is it worth the $259 price?
If your needs match its strengths — a small, maintained lawn and weekly mowing — it offers fair value for the cordless convenience. If you need power, runtime, or a taller cut, the same money stretches further on a higher-voltage machine, and the 3.2-star review average reflects that gap between marketing and performance.
