The X350 pairs wire-free RTK plus vision navigation with a 1.5 acre recommended capacity, 50% slope ability, and a fast 80 minute recharge that yields up to 200 minutes of runtime per the maker's lab-tested figures. A 3 year warranty, IP66 rating, and 60 dB(A) standard-mode noise round out a strong published spec sheet for larger suburban lawns.

How we sourced this

Every spec above is traced to the manufacturer's own published figures. Where the maker publishes no usable number, the field reads “Not published” rather than an estimate.

Notes & caveats

Variant chosen: Navimow X350, the 1.5 acre model in the current US X3 series (X315 0.5 acre, X330 1.0 acre, X350 1.5 acres, X390 2.5 acres), which has the fullest published US spec table. Pricing: product page regular (list) price is $2,799.00 with a sale price of $2,239.00 as of 2026-07-05; the X3 Specs and Compare page still shows a launch MSRP row of $3,499 for the 1.5 acre model, so the current list price from the product page is used here. Runtime basis: 80 min Charging Time and 200 min Full Charge Mowing Time are published rows in the X3 Spec and Compare table; the lab-testing footnote on the product page reads that 30 minutes of charging provides up to 90 minutes of operating time covering up to 5,380 sq ft, based on internal laboratory testing. Noise basis: tested in standard mode with a maximum noise level of 60 dB(A). Battery 10Ah; maximum mowing speed published as 3.3 ft/s; rear-wheel drive. Multi-zone management is advertised as a feature in the product description; a maximum zone count is not published.
