Best Robot Mowers for Large Lawns Ranked

13 robot mowers rated for lawns of 1 acre and up.

Last updated: October 21, 2026

Robot mowers for an acre or more cost the most up front but usually the least per acre, and they replace the most hours on a riding mower. Wide or twin cutting discs, all-wheel drive and a 4G connection are common here. Check the slope rating against your steepest bank, not the average grade.

Prices were last checked October 21, 2026 and are subject to change; the price and availability shown by the retailer at the time of purchase apply.

  1. Lymow One Plus (10A)
    #1 of 134.5Full review

    For big, hilly properties approaching two acres, where the faster charger lets the tracked One Plus cover more ground each day. Smaller yards don’t need its bulk.

  2. Mammotion LUBA 2 AWD 5000HX
    #2 of 134.4Full review

    For hilly lawns up to 1.25 acres where a discounted RTK all-wheel-drive mower beats paying more for the LiDAR-equipped LUBA 3.

  3. Lymow One Plus (5A)
    #3 of 134.3Full review

    For large, steep or rough properties of about an acre that wheeled robot mowers can’t handle. The tracked drive and wide deck come with a lot of weight and price.

  4. Worx Landroid Vision Cloud 4WD 1.5 Acre (WR346)

  5. Dreame A3 AWD Pro 5000
    #5 of 134.2Full review

    For estates of about an acre with slopes and trees, where its larger battery and LiDAR navigation earn the price. It’s overkill for anything under half an acre.

  6. Segway Navimow X390
    #6 of 134.0Full review

    For lawns up to about 2.5 acres that want reliable wire-free mowing with good obstacle avoidance. Skip it for very steep yards, which need an AWD mower.
