WORX Robot Mowers at a Glance
The lineup splits into two main groups based on size and drive. The WR320 and WR310 use Vision AI for wire-free mapping on half-acre and quarter-acre lawns. The WR220 and Landroid Vision 1/2 Acre also offer wire-free setup but focus on uneven terrain navigation. These models prioritize smart obstacle avoidance and automated zone management for modern yards.
For larger or steeper properties, the WR155E and Landroid L 20V provide different solutions. The WR155E is self-propelled, which helps on slopes, while the Landroid L uses a 20V battery system with a floating blade for consistent cuts. You should choose based on whether you need self-propelled power or advanced AI navigation for flat, wire-free areas.

Who Should Choose WORX
WORX covers yards from a quarter-acre up to half-acre, plus a 2000-square-meter self-propelled model for steep slopes. All listed units use wire-free Vision AI navigation and app control. You will find two-wheel drive options for precision and a self-propelled version for heavy grades. Sizes range from compact 15-inch widths to 21.7-inch decks. Heights stay low, mostly under 12 inches, except the self-propelled WR155E. No models support boundary wires. Larger properties over half-acre are not covered. The range focuses on smart, automated mowing for medium-sized residential lawns.
How to choose the right WORX robot mower
Match lawn size to capacity
Start by checking the maximum coverage area. The WR310 handles up to a quarter-acre, making it ideal for compact yards. The WR320 and WR220 are rated for half-acre lawns, providing more coverage for medium-sized spaces. If you have a larger garden with steep grades, the WR155E supports up to 2000 square meters. Selecting the correct size ensures the mower can complete its cycle without running out of battery or missing patches.
Check navigation technology type
Navigation determines how the mower maps your yard. The WR320 and WR310 use Vision AI combined with RTK for high-precision, wire-free mapping. The WR220 relies on Vision AI alone, which is still effective but lacks the extra positional accuracy of RTK. If you want the most precise edge trimming and zone management, look for models that include RTK technology alongside standard vision sensors for reliable boundary detection.
Consider drive type for slopes
Drive type affects performance on uneven ground. Most models here are two-wheel drive, which offers precision on flat or gently sloping terrain. The WR155E is self-propelled, making it better suited for large gardens with steep grades where you need extra traction and edge-to-edge cutting reliability. If your yard has significant inclines, a self-propelled unit will handle the terrain more effectively than a standard two-wheel drive model.
Review physical dimensions and weight
Size matters for storage and maneuverability. The WR220 is the most compact at 9.3 inches tall and weighs only 34.8 pounds. The WR320 is slightly taller at 11.3 inches and weighs 44.5 pounds. The WR155E is the largest, standing 39.8 inches tall and weighing 45.2 pounds. Measure your storage space and check if the mower can fit through narrow gates before deciding, as dimensions vary significantly across the lineup.
Verify power and battery specs
Power sources differ across the range. The WR155E uses a 20V system with a 5.0 Ah battery for extended runtime on larger areas. Other models like the WR320 and WR310 rely on internal batteries optimized for their specific acreage limits. Check the voltage and capacity if you plan to use the mower for longer sessions. Higher capacity batteries generally support longer mowing times, ensuring the unit completes its task without frequent recharging.
