The i210 AWD within the i2 AWD series
Navimow sells the i2 AWD in two versions and one manual covers both. The i210 AWD is the version with the 5.1 Ah battery: Navimow's product page gives it a 5.1 Ah battery, a recommended mowing area of 0.25 acre and 120 minutes of mowing per full charge, and the manual lists a 5.1 Ah, 110 Wh pack at 21.6 volts.
Navimow's product page lists what is in the box as the mower, an antenna installation kit, the charging station and its installation kit, a GNSS antenna, pegs, the power supply, spare blades and bolts, and the important information and quick start guide.
The product page also says antenna installation is not required, and describes Network RTK with free cellular data as the positioning service. The manual calls the antenna optional and describes installing it only where the Network RTK service is not supported.
How it finds its way without a wire
Navimow calls the positioning system EFLS NRTK: tri-frequency Network RTK fused with a vision camera. The manual says that where the Network RTK service is supported, it activates automatically at first activation and is free of charge, with no additional hardware required.
Where it is not supported at activation, the manual says it will not be activated, but may become supported later, at which point you switch from local RTK to Network RTK in settings. Navimow's product page says Network RTK comes at no extra cost and the required cellular data is free.
Mapping is automatic according to Navimow, and the listing describes one-tap auto mapping. A product-page footnote says map storage supports up to 1.2 times the recommended mowing area. The app manages up to 20 zones.
Coverage, runtime and the numbers behind 0.25 acre
Navimow's comparison table for the i210 AWD lists 0.25 acre as the recommended mowing area, with a 16-hour time figure for that area. It gives 120 minutes of charging time, 120 minutes of mowing per full charge, 0.06 acre per charge and 0.03 acre per hour.
The manual's footnote says those runtime figures were tested at standard cutting speed with a full battery at 25 degrees Celsius on a fresh-cut lawn, and that wet or long grass lowers capacity. The listing's figure of 2,690 square feet per charge does not appear in the Navimow documents we read.
Cutting height is 2 to 3.6 inches, adjusted manually, with a 7.1 inch cutting width from one disc with five blades. The manual lists the blade motor at 2,500 rpm and recommends replacing all blades and their screws every one to two months with original Navimow blades, model X3A06E.
Slopes, obstacles and weather
Maximum slope is 45 percent, or 24 degrees, both inside the working area and at the boundary according to the manual. Navimow's footnote says the slope figure was measured on dry grass cut to 1.97 inches, with no obstacles on the slope.
Navimow lists a vertical passing ability of 1.57 inches, measured on flat ground with the blade set at 3.6 inches, and 9.8 inch off-road wheels with all-wheel drive and electronic stability control. It claims up to 30 percent energy savings, with a footnote citing a test at 77 degrees Fahrenheit against full-time three-wheel drive.
VisionFence uses a 140 degree RGB camera, and Navimow claims recognition of over 150 obstacle types. The product page says the mower detects rain, frost, snow, strong wind or heat and returns to charge. The manual lists an operating range of 0 to 40 degrees Celsius, with 10 to 35 recommended.
Size, weight, noise and ratings
Navimow's manual and product page both give the mower as 21.4 by 15.1 by 11.2 inches with a net weight of 27.12 pounds. The listing gives 33.5 by 24 by 13.8 inches and 49 pounds. We are reporting both; the listing does not say whether its figures include the station or packaging.
The manual lists a measured sound power level of 59 dB(A) and a sound pressure level of 51 dB(A). The mower body and charging station are rated IP66 and the power adapter IP67. The power supply takes 100 to 240 volts AC and the low-voltage cable is 23 feet.
The manual asks that the mower and its peripherals be connected only to a circuit protected by a residual current device rated at 30 mA or less. It also says not to use a high-pressure washer; a soft brush, cloth or water hose is fine for the exterior, chassis and wheels.
Connectivity and warranty
Navimow lists Bluetooth, Wi-Fi and cellular connectivity, with Alexa and Google Home support and GPS tracking, out-of-boundary and lift alarms and a PIN code. Its comparison table lists the Connect+ cellular service as one year free and renewable annually after that.
The manual's warranty table gives 3 years for the i210 AWD and 2 years for battery packs and power adapters, and Navimow's product page states the same split. The warranty starts from the later of the purchase date and first activation date, and blades are excluded as disposable.
The manual also says battery damage caused by overdischarge is not covered. It asks that a new mower be fully charged before first use, since it may be low after long storage.
