Greenworks Optimow 10
Best OverallPros
- GPS navigation reduces boundary wire needs
- Strong battery life for medium lawns
- Quiet operation at 58 dB
Cons
- Setup can be time-consuming
- Not suitable for slopes over 25 degrees
The Greenworks Optimow 10 strikes a balance between features and price. It uses GPS to map your lawn, which means less boundary wire to bury. Owners report reliable daily mowing with good pattern coverage, and the 24V 4.0Ah battery handles a 0.25-acre lawn on a single charge.
Build quality is solid, with a durable plastic shell and sharp stainless steel blades. The mower returns to its charging station automatically when the battery is low. Some users note that the initial boundary wire setup requires patience, but once configured, the Optimow 10 runs consistently.
Greenworks Optimow 15
Best for Large LawnsPros
- Wider cutting deck for faster mowing
- Handles larger lawns up to 0.5 acre
- Good hill climbing ability
Cons
- Higher price point
- Heavier unit at 12 kg
The Optimow 15 is built for bigger properties. Its 22 cm cutting deck covers more ground per pass, and the larger 5.0Ah battery ensures it can finish a 0.5-acre lawn without needing a recharge. GPS mapping helps it navigate efficiently, and it handles moderate slopes well.
Owner reviews highlight its robust construction and reliable daily performance. The mower is heavier than smaller models, which can make lifting it over obstacles more challenging. However, for large, open lawns, the Optimow 15 is a powerful and dependable choice.
Greenworks 24V Robotic Mower
Best BudgetPros
- Very affordable entry price
- Simple setup and operation
- Shares battery with Greenworks 24V tools
Cons
- Limited to small, simple lawns
- No GPS, requires full boundary wire
The Greenworks 24V Robotic Mower is the most accessible model in the range. It uses a standard boundary wire system, making it ideal for small, rectangular lawns. The 16 cm cutting width is sufficient for a 0.12-acre area, and it runs on the same 24V battery platform as other Greenworks tools.
Owners appreciate the straightforward setup and low cost. It is not as advanced as the Optimow series, lacking GPS and app features. But for a budget-conscious buyer with a small lawn, it delivers reliable, no-fuss mowing.
Greenworks Optimow 7
Best for Small LawnsPros
- GPS navigation for efficient mowing
- Compact size for tight spaces
- Good battery life for small lawns
Cons
- Small cutting deck takes longer
- Not for lawns over 0.15 acre
The Optimow 7 is a compact robotic mower with GPS capabilities, making it a smarter choice for small lawns than the basic 24V model. It covers up to 0.15 acre and uses GPS to reduce the need for extensive boundary wire. The 16 cm cutting deck is fine for smaller areas.
Owner reviews note its quiet operation and reliable return-to-base function. It is a good middle ground between the budget model and the larger Optimow 10. The smaller battery means it may need to recharge for larger lawns within its range, but for a small yard, it works well.
Greenworks Optimow 5
Best for Compact SpacesPros
- Smallest footprint for tight gardens
- Lightweight and easy to move
- Low cost for very small lawns
Cons
- Very limited area coverage
- No GPS, basic navigation only
The Optimow 5 is the smallest and most affordable model in the Optimow line. It is designed for very small lawns, patios, or courtyard gardens up to 0.1 acre. The 14 cm cutting width is narrow, but it is nimble and can navigate tight corners and narrow passages.
Owners find it easy to set up and use, though it lacks the GPS features of the higher models. It relies entirely on a boundary wire. For a tiny lawn that needs regular trimming, the Optimow 5 is a simple, effective solution.
What to check before buying a Greenworks robotic mower
Before you choose a model, measure your lawn area accurately. Greenworks robotic mowers are rated for specific maximum areas, and exceeding this can lead to the battery running out before the job is done. Also, consider the complexity of your lawn. Simple, open lawns work well with boundary wire systems, while lawns with many obstacles or irregular shapes benefit from GPS navigation found in the Optimow 7, 10, and 15.
Check the slope of your lawn. Most Greenworks robotic mowers can handle slopes up to 25 degrees. Steeper hills may cause the mower to get stuck or lose traction. Finally, think about your existing Greenworks battery ecosystem. The 24V models share batteries with other Greenworks 24V tools, which can be a cost-saving advantage.
Mistakes to avoid when buying a robotic mower
A common mistake is buying a mower that is too small for your lawn. This results in the mower needing to recharge mid-cycle, which can double the total mowing time. Always choose a model rated for a larger area than your actual lawn size for best results.
Another error is ignoring the boundary wire installation. Some models require you to bury the wire, while others allow it to be pinned to the surface. Not planning the wire layout properly can lead to the mower missing sections or crossing into flower beds. Take time to map out the wire path before installation.
FAQs
Do Greenworks robotic mowers need a boundary wire?
Yes, all Greenworks robotic mowers require a boundary wire to define the mowing area. Models with GPS can reduce the amount of wire needed but still require it for the charging station and perimeter.
Can Greenworks robotic mowers handle wet grass?
It is not recommended to mow wet grass as it can clog the blades and affect performance. Most owners report better results on dry grass.
How long does the battery last on a Greenworks Optimow 10?
The 4.0Ah battery typically runs for 60-90 minutes depending on grass condition and terrain. It then returns to the charging station automatically.
Are Greenworks robotic mowers quiet?
Yes, they operate at around 58-62 dB, which is quieter than a traditional gas mower. They can run at night without disturbing neighbors.
Do I need to install a GPS antenna for the Optimow models?
No, the GPS module is built into the mower. It uses satellite signals to map the lawn and improve navigation efficiency.
Can I use a Greenworks robotic mower on a sloped lawn?
Yes, but only on slopes up to 25 degrees. Steeper slopes may cause the mower to slip or get stuck.
What is the warranty on Greenworks robotic mowers?
Greenworks offers a 2-year warranty on most robotic mowers. Always check the specific model for warranty details.
Do Greenworks robotic mowers come with a charger?
Yes, each mower includes a charging station and power adapter. The mower docks itself automatically when the battery is low.
Can I control a Greenworks robotic mower with an app?
The Optimow 7, 10, and 15 models have app connectivity for scheduling and monitoring. The basic 24V model does not have app support.
How often should I replace the blades on a Greenworks robotic mower?
Blades should be replaced every 2-3 months depending on usage. Dull blades can tear grass instead of cutting it cleanly.
Will a Greenworks robotic mower work in winter?
It is not recommended to use them in snow or freezing temperatures. Store the mower indoors during winter to protect the battery and electronics.
Can I use a Greenworks 24V battery from another tool in the robotic mower?
Yes, the 24V robotic mower is compatible with all Greenworks 24V batteries. This allows you to swap batteries from other tools for extended runtime.
Our verdict
For most homeowners, the Greenworks Optimow 10 is the best overall robotic mower, offering a reliable GPS system and strong battery for medium lawns. If you have a larger property, the Optimow 15 is worth the upgrade. For budget buyers with small, simple lawns, the Greenworks 24V Robotic Mower provides excellent value.
