Key specs for choosing your mower
Check yard size limits
You must match the mower’s application rating to your lawn area. The Greenworks C20Z is rated for half an acre. This limit ensures the battery lasts for your entire yard without mid-cut recharging. If your lawn exceeds this size, the unit may struggle to finish the job. Larger models handle more ground but often require different navigation systems. Always compare the square footage or acreage rating in the specs. Choosing a mower with insufficient capacity leads to incomplete cuts and frequent charging cycles.
Match slope capability
Slope handling varies significantly between models. The Greenworks C20Z manages slopes up to 24 degrees using wire-free navigation. In contrast, the AIWEYA AWY-550 handles a 45% slope via remote control. You need to convert your yard’s grade to the correct metric for comparison. Steep terrain requires robust traction and a drive type that prevents slipping. If your yard has sharp inclines, autonomous units may fail. Remote-controlled crawlers offer better grip for severe grades. Check the percentage or degree rating before buying.
Select the right drive type
Drive type determines how you operate the machine. The Greenworks C20Z uses app control for autonomous mowing. You set zones and let it work. The AIWEYA models use remote control for manual operation. This gives you direct command over movement on tricky terrain. You should choose app control for convenience on flat or moderately sloped lawns. Choose remote control for steep or complex areas where precision matters. The drive type also affects safety and supervision needs. Autonomous units work alone, while remote units require your presence.
Consider cutting width
Cutting width affects how many passes you need. The Greenworks C20Z has an 11.8-inch width. This smaller size allows it to navigate tight spaces and obstacles. The AIWEYA AWY-550 features a 22-inch width. This doubles the coverage per pass but requires more open space. You should pick a width that fits your yard’s layout. Narrow mowers are better for gardens with many trees. Wide mowers are faster for large, open areas. The width also impacts the unit’s overall footprint and storage size.
Review physical dimensions
You must ensure the mower fits your storage space. The Greenworks C20Z measures 25.4 inches in length and 16.5 inches in height. It weighs 27.6 pounds, making it easy to move. The AIWEYA AWY-550 is much larger at 38.5 inches long and 36 inches high. It weighs 286 pounds. You need a garage or shed that accommodates these dimensions. Heavy units are harder to transport for maintenance. Check the length, width, and height in the specs. Ensure your storage area has enough clearance for the largest unit you consider.
Frequently asked questions
Can electric robot lawn mowers handle steep slopes?
Yes, but capability varies significantly by model. The Greenworks C20Z handles slopes up to 24 degrees using wire-free navigation. For steeper terrain, the AIWEYA AWY-550 and INFRONT RC550S offer remote control with a 45% slope capability. You must match the mower’s rated slope angle to your yard’s gradient to ensure safe operation.
Do I need boundary wires for a robotic mower?
Not necessarily. The Greenworks C20Z features a wire-free boundary setup, allowing you to skip physical perimeter installation. It uses RTK technology for precise mapping. Other models on this list use remote control, which also eliminates the need for boundary wires. You can choose based on whether you prefer autonomous navigation or manual control.
What is the maximum yard size these mowers cover?
The Greenworks C20Z is rated for applications up to 1/2 acre. This limit ensures the battery lasts for your entire lawn without mid-cut recharging. The other models focus on slope handling rather than specific acreage ratings. You should verify the application rating matches your lawn area before purchasing.
Can these mowers be used for snow clearing?
Some models support this function. The INFRONT RC550S is described as suitable for snow clearing and comes with a snow plow attachment. The AIWEYA AWY-550 and AWY-550S also list snow plow attachments in their specifications. You can use these units for winter maintenance if you select the versions equipped with the plow.
How do I control the mower if it is not autonomous?
You use a remote control device. The INFRONT RC550S and all AIWEYA models listed use remote control drive types. This allows you to manually guide the mower over steep or uneven terrain. You retain precise maneuvering capabilities, which is useful for complex landscapes where autonomous navigation might struggle.
Are these mowers heavy and difficult to move manually?
They are substantial units. The Greenworks C20Z weighs 27.6 pounds. The remote-controlled models are much heavier, weighing 286 pounds for the AIWEYA units and 309 pounds for the INFRONT model. You will likely need assistance to lift or transport these heavier units, especially if installing them on difficult terrain.
Do these mowers have smart obstacle avoidance features?
The Greenworks C20Z includes smart obstacle avoidance technology. It also offers app control for zone management and monitoring. The remote-controlled models rely on your manual input for navigation rather than autonomous sensors. You get precise control, but you must actively manage the mower’s path around obstacles.
