Greenworks 10-Inch Robotic Mower
Best OverallPros
- Simple boundary wire setup
- Quiet operation at 60 dB
- Reliable rain sensor
Cons
- Not for lawns over 0.25 acre
- No app connectivity
The Greenworks 10-Inch Robotic Mower is the sweet spot in the lineup. It handles flat to moderately sloped lawns up to 0.25 acres with ease. Owners report that the boundary wire installation is straightforward, and the mower follows a systematic pattern rather than random bouncing, which means fewer missed spots.
Battery life is rated at 60 minutes, which is enough to cover a typical 0.25-acre lawn in one charge. The rain sensor works well, automatically returning the mower to its charging station when precipitation is detected. Build quality is solid for the price point, with a durable plastic shell that withstands bumps from garden furniture and rocks.
Greenworks 12-Inch Robotic Mower
Best for Larger LawnsPros
- Longer 90-minute runtime
- Handles steeper slopes
- Wider cutting deck
Cons
- Heavier and harder to move
- Higher price point
The 12-inch model is designed for homeowners with medium-sized lawns up to 0.5 acres. The larger battery and wider cutting deck mean fewer charging cycles and faster mowing times. Owners appreciate the improved slope handling, with many reporting it handles 25-degree inclines without slipping.
This model also includes a more robust motor that cuts through thicker grass without bogging down. The build quality is a step up from the 10-inch version, with reinforced wheels and a sealed bearing system for longer life. The main trade-off is weight, at 20 pounds it is noticeably heavier to carry around for storage.
Greenworks 8-Inch Robotic Mower
Best Budget PickPros
- Very affordable entry point
- Lightweight and easy to carry
- Simple controls
Cons
- Limited to 0.15 acre lawns
- Struggles on slopes over 15 degrees
The 8-inch model is the most affordable way to get into robotic mowing. It is ideal for small, flat lawns under 0.15 acres. Owners say it is easy to program with the basic timer controls and the boundary wire setup is the simplest in the range. It is also the lightest model at just 12 pounds, making it easy to move around.
However, the smaller battery means it needs to recharge more frequently, and the cutting width means it takes longer to cover the lawn. It is best suited for very small yards or as a secondary mower for tight spaces. Build quality is adequate, but the plastic feels thinner than the larger models.
Greenworks 14-Inch Pro Robotic Mower
Best for Complex TerrainPros
- Handles steep slopes up to 30 degrees
- Large battery for extended runtime
- Wider cutting deck for efficiency
Cons
- Expensive
- Heavy and bulky to store
The Pro model is the flagship of the Greenworks robotic mower line. It is built for challenging terrain with steep slopes and larger lawns up to 0.75 acres. The 14-inch cutting deck and 6.0Ah battery mean it can mow for up to 2 hours on a single charge, covering ground quickly.
Owners report that it navigates complex gardens with multiple flower beds and narrow paths better than smaller models. The wheels are larger and have deeper treads for better traction. The build quality is the best in the range, with a reinforced chassis and sealed electronics. The main downside is the price, which puts it in competition with premium brands like Husqvarna and Worx.
Who is the Greenworks Robotic Mower for?
Greenworks robotic mowers are designed for homeowners who want a hands-off approach to lawn maintenance. They are best suited for small to medium-sized lawns that are relatively flat or have gentle slopes. The lineup covers lawns from 0.15 acres up to 0.75 acres, so there is a model for most suburban properties.
These mowers are particularly good for people who travel frequently or have busy schedules. The programmable timer allows you to set a mowing schedule for the week, and the mower will automatically return to its charging station when the battery is low or when rain is detected. They are also quieter than gas mowers, making them suitable for use early in the morning or late in the evening without disturbing neighbors.
Performance and Cutting Quality
The cutting performance of Greenworks robotic mowers is generally good for the price range. They use a floating cutting deck that adjusts to the contours of the lawn, which helps prevent scalping on uneven ground. The blades are made of hardened steel and are designed to be replaced easily when they dull.
Owner reviews indicate that the mowers produce a clean cut on grass up to 4 inches tall. For taller grass, it is recommended to mow more frequently or manually cut the lawn down to size before the first robotic mow. The mowers do not have a bagging option, so they use a mulching system that returns clippings to the lawn as fertilizer. This is fine for most lawns, but some owners prefer a cleaner look.
Build Quality and Warranty
Greenworks has a reputation for building reliable outdoor power equipment, and their robotic mowers are no exception. The plastic housings are UV-resistant and hold up well to sun exposure. The wheels are made from a durable rubber compound that provides good traction without leaving marks on patios or walkways.
The warranty on Greenworks robotic mowers is typically 2 years for the mower and 1 year for the battery. This is standard for the industry. Some owners have reported issues with the boundary wire breaking after a few seasons, but this is a common problem with all boundary-wire-based robotic mowers and is easy to fix with a splice kit.
What to Check Before Buying a Robotic Mower
Before purchasing a Greenworks robotic mower, consider the size and shape of your lawn. Measure the total area and note any slopes, flower beds, or obstacles. The mower requires a boundary wire to be installed around the perimeter of the lawn, which can take a few hours to set up. Make sure you have a power outlet near the charging station location.
Also check the maximum slope rating. The 8-inch model handles 15 degrees, the 10-inch handles 20 degrees, the 12-inch handles 25 degrees, and the 14-inch Pro handles 30 degrees. If your lawn has slopes steeper than these ratings, the mower may get stuck or fail to cut properly.
Mistakes to Avoid When Using a Robotic Mower
One common mistake is not setting up the boundary wire correctly. If the wire is too close to obstacles, the mower may get stuck or miss areas. Leave at least 12 inches of clearance around flower beds, trees, and fences. Another mistake is not mowing frequently enough. Robotic mowers work best when used daily or every other day to keep grass at a consistent height.
Do not expect the mower to handle leaves or debris. Clear the lawn of sticks, toys, and large leaves before each mowing session. Finally, do not ignore the maintenance schedule. Clean the blades and underside of the mower regularly to prevent grass buildup that can affect performance.
FAQs
Do Greenworks robotic mowers need a boundary wire?
Yes, all Greenworks robotic mowers require a boundary wire to be installed around the perimeter of the lawn to define the mowing area.
Can Greenworks robotic mowers handle wet grass?
They have a rain sensor that automatically returns the mower to the charging station when rain is detected, so they are not designed to mow wet grass.
How long does it take to install the boundary wire?
Installation typically takes 1 to 3 hours depending on the size and complexity of your lawn.
Do Greenworks robotic mowers come with a remote control?
No, they are controlled via a simple control panel on the mower itself, not a remote control or smartphone app.
Can the mower handle slopes?

Blades should be replaced every 2 to 3 months depending on usage and the type of grass.
Is the mower safe for pets and children?
Yes, the mower has safety sensors that stop the blades if the mower is lifted or tilted.
What happens if the battery runs out while mowing?
The mower automatically returns to the charging station when the battery is low, recharges, and then resumes mowing.
Can I use the mower on a lawn with flower beds?
Yes, but you need to install the boundary wire around the flower beds to keep the mower out.
Does the mower work in the dark?
Yes, the mower can operate in low light conditions, but it does not have headlights for nighttime mowing.
How loud is the Greenworks robotic mower?
It operates at around 60 decibels, which is quieter than a gas mower and comparable to a normal conversation.

Our verdict
The Greenworks 10-Inch Robotic Mower is the best overall pick for most homeowners, offering a great balance of performance, reliability, and value. For those with larger lawns or steeper slopes, the Greenworks 12-Inch or 14-Inch Pro models are worth the upgrade. The 8-Inch model is a solid budget option for very small, flat lawns.
