SENIX Gas Lawn Mower, 22" Self Propelled vs WORX Nitro Cordless Lawn Mower, 21" Elec
Quick Verdict
The WORX Nitro Cordless Lawn Mower wins for most homeowners who want low-maintenance operation and variable speed control. It offers a higher user rating (4.4 vs 4.0) and eliminates gas, oil, and pull-start hassle. However, the SENIX Gas Lawn Mower is the better choice if you have a large yard (over half an acre) or need maximum cutting power without worrying about battery runtime. The SENIX also costs about $35 less upfront.

Where SENIX Wins
More cutting power for tough conditions. The 17 hp gas engine delivers consistent torque through thick, wet, or overgrown grass that can bog down cordless mowers. If you let your lawn get tall between cuts, the SENIX will power through without slowing down.
No battery limitations. Gas mowers run as long as you have fuel. For yards over half an acre, you won’t need to stop to recharge or swap batteries. The 22-inch cutting deck also covers slightly more ground per pass than the WORX’s 21-inch deck, saving time on larger lawns.
Lower upfront cost. At $395.10, the SENIX is about $35 less than the WORX. If you’re on a tighter budget and don’t mind the maintenance of a gas engine, this is a solid value for a self-propelled mower.
Proven reliability with many reviews. With nearly double the number of reviews (463 vs. 244), the SENIX has a larger sample size of user experiences, which can help you gauge long-term durability.
Where WORX Wins
No gas, no fumes, no maintenance. The WORX Nitro runs on an 80V battery, which means no oil changes, spark plug replacements, or fuel stabilizer needed. You just charge and go. This is a major convenience for homeowners who want a clean, quiet mowing experience.
Variable speed control. The WORX offers variable self-propelled speed, letting you adjust the mower’s pace to match your walking speed. The SENIX likely has a fixed-speed drive system, which can feel too fast or too slow depending on your terrain.
Higher user satisfaction. With a 4.4-star average from 244 reviews, the WORX scores notably higher than the SENIX’s 4.0. This suggests fewer issues with starting, build quality, or overall performance.
Lighter and easier to maneuver. Cordless mowers are generally lighter than gas models, making them easier to push manually (if the self-propel fails) and simpler to store or transport.
