Key specs to compare for 1/2 acre
Check cutting width for speed
The cutting width determines how many passes you need to cover your yard. A wider blade mows more ground per hour. The WORX Landroid Vision Wire-Free has the widest 19.2-inch cut on this list. The Greenworks C20Z offers a narrower 11.8-inch width. You should choose a wider mower if you want faster coverage. A narrower unit provides better precision in tight spaces. Compare the width spec to estimate your total mowing time. This is a primary factor for efficiency on medium-sized lawns.
Review navigation technology type
Navigation technology dictates how the mower maps your yard. LiDAR and Vision AI offer precise wire-free setups. The ECOVACS Goat A2000 uses LiDAR for accurate mapping. The WORX WR320 combines Vision AI with RTK for high precision. The Greenworks C20Z uses wire-free navigation without specifying the exact sensor type. You should select a system that matches your terrain complexity. Advanced sensors help avoid obstacles and map edges better. Check the attributes section to see which technology each model uses.
Consider battery voltage compatibility
Battery voltage affects power and compatibility with existing tools. The WORX Landroid L 20V uses a 20V system. It comes with a 5.0 Ah battery for sustained runtime. This model is ideal if you already own WORX 20V equipment. You can share batteries across multiple tools to save cost and storage. Other models on this list do not list their voltage in the attributes. You should check this spec if you want to integrate the mower into your current tool ecosystem.
Assess unit weight for handling
Weight impacts how easy the mower is to move during setup. The Greenworks C20Z is the lightest at 27.6 pounds. The WORX WR320 is heavier at 44.5 pounds. A lighter unit is easier to carry up or down slopes. You should consider weight if your yard has significant elevation changes. Heavier units may offer more stability on uneven ground. Check the weight spec to determine if you need assistance moving the unit. This is a practical consideration for installation and maintenance.
Verify edge mowing capabilities
Edge mowing determines if the mower cuts grass right up to fences. The ECOVACS Goat A2000 features built-in edge mowing. This reduces the need for manual trimming along borders. The Greenworks C20Z and WORX WR320 focus on obstacle avoidance. You should check the smart features for edge mowing if you want minimal manual work. This spec is crucial for maintaining a neat appearance without extra effort. Verify this capability in the attributes before purchasing.
