    For half-acre yards with real slopes, where its all-wheel drive beats two-wheel RTK mowers at a similar price. Flat lawns can do with a cheaper model.

  2. Sunseeker S4

    For quarter-acre suburban yards with trees or walls that block satellite signal, where a LiDAR mower avoids RTK setup. Yards with steep slopes need an AWD model.

  3. Sunseeker X3 Plus

    For small, fairly flat, open suburban lawns where buyers want wire-free mowing on a budget. Hilly or heavily shaded yards should look elsewhere.

    For small, clearly bordered lawns where a simple, cheap wire-free mower is enough. Larger or open-edged yards are better served by an RTK or LiDAR model.
