WORX vs Dreame Key Specs
Drive type
Edge: Dreame A3 AWD Robot Lawn Mower
The WORX WR320 uses a Two-Wheel Drive system, which is standard for many robot mowers. This setup works well on flat or gently sloping lawns. In contrast, the Dreame A3 AWD features All-Wheel Drive. This system provides heavy-duty traction, allowing the mower to handle steep inclines up to 80% (38.7°) and climb obstacles as high as 2.17 inches. If your yard has rolling hills or uneven terrain, the AWD system offers superior stability and power compared to the two-wheel configuration.
Slope capability
Edge: Dreame A3 AWD Robot Lawn Mower
Slope handling is a critical specification for many homeowners. The WORX WR320 is rated for slopes up to 30%. This is sufficient for typical residential yards with moderate grading. The Dreame A3 AWD significantly outperforms this, handling slopes up to 80% or 38.7 degrees. This high rating means the Dreame can tackle steep hills that would likely stall or slip a standard two-wheel drive mower. For properties with significant elevation changes, the Dreame’s capability is clearly superior.
Cutting width
Edge: WORX WR320 Robot Mower for 1/2 Acre
The cutting width determines how much grass the blade covers in a single pass. The WORX WR320 has a cutting width of 18.1 inches. The Dreame A3 AWD is slightly narrower at 17.1 inches. While the WORX covers a bit more ground per pass, the difference is minimal. Both widths are effective for efficient mowing on lawns up to half an acre. The WORX has a slight edge in raw coverage area, but it does not drastically impact overall mowing time.
Weight and build
Edge: Tie
Weight affects stability and portability. The WORX WR320 weighs 44.5 pounds, making it a substantial unit that likely stays firmly planted during operation. The Dreame A3 AWD is lighter at 26.4 pounds. This weight difference may make the Dreame easier to move if you need to transport it between locations or store it away. However, the heavier WORX may feel more robust on the ground. The lighter Dreame offers easier handling, while the WORX offers more mass.
Dimensions
Edge: WORX WR320 Robot Mower for 1/2 Acre
Physical size matters for storage and fitting through gates. The WORX WR320 measures 22.7 inches in length, 18.1 inches in width, and 11.3 inches in height. The Dreame A3 AWD is longer at 25 inches, narrower at 17.1 inches, and slightly taller at 11.6 inches. The WORX is more compact in length, which might fit better in tight storage spaces. The Dreame’s greater length could help with stability on uneven ground. Both have similar footprints, so check your storage area dimensions carefully.
