Segway Navimow X390 vs X450: Which One Should You Buy?
A straight look at segway navimow x390 vs x450 from the listings supplied, with the Navimow mowers listed for 1/4 acre lawns and X390 covers that are actually listed.
On this page
A lawn that maps itself sounds easy until trees, narrow passages and slopes get in the way. A robot mower must find its boundary, avoid garden objects and keep mowing after a recharge, and the wrong match leaves patches or a mower stuck at the edge of the lawn. This guide answers segway navimow x390 vs x450 in plain terms: the listings supplied here do not include a mower listing for either model, so a deck to deck or battery to battery verdict between those mowers cannot be drawn from these listings. What the listings do include is a pair of Navimow mowers listed for 1/4 acre lawns and covers listed for the X390, and this guide sets out what each listing states, where each item fits, and what to weigh before buying.

segway navimow x390 vs x450: what the listings actually compare
The honest starting point is the gap in the listings. No listing here describes an X390 mower or an X450 mower, their cutting widths, their batteries or their acreage limits, so this guide does not rank those mowers against each other and does not claim a winner between them. The listings that are here describe Navimow mowers listed for 1/4 acre lawns and covers made to fit over an X390, and those items are the gear section below, ranked by the strength of what each listing states. If your shortlist is fixed on an X390 or an X450 mower, use this guide to learn how Navimow mapping, obstacle avoidance and slope handling are described in listings, then look for a mower listing for the exact model before deciding.
| Item | What the listing states | Limit |
|---|---|---|
| Segway Navimow i110N | RTK plus vision mapping, virtual boundaries, obstacle avoidance | Listed for a 1/4 acre lawn in its title |
| Segway Navimow i210 AWD | AWD, zero-turn steering, multi-zone app control | Garage ships separately, per its title |
| Generic cover for X390 | Cover listed for the X390, with a storage bag | Listing also describes it as a zero-turn cover, which does not match a robot mower |
| YNCTCWX cover for X390 | 600D Oxford fabric, reflective strip, elastic hem | A cover only, not a mower, and no warranty term is stated |
Gear in this guide, ranked by stated specs
The gear below is ranked from the strongest listing to the weakest listing for a robot mower buyer, with covers ranked below mowers because a cover does not mow.
Segway Navimow i110N Robot Lawn Mower leads this gear section because its listing states the fullest set of mower features. Its listing states EFLS 2.0 with RTK positioning enhanced by vision sensors, for stable, centimeter-level navigation accuracy. Its listing states wire-free setup with virtual boundaries mapped from a smartphone, plus AI-assisted mapping that identifies lawn edges during mapping. Its listing states planned mowing patterns, a change of mowing direction after 100% coverage to minimize tracks, intelligent recharging, and mowing until the job is done. Its listing states a 140° field-of-view camera with built-in algorithms that can detect 150+ types of common garden objects, for obstacle avoidance and a higher level of safety. Its listing states a 58dB(A) quiet level, a package with 9 spare blades and bolts and 10 pegs for the extension cable, and a full 3-Year Warranty. Its title lists the lawn size as 1/4 Acre, and its spec table lists dimensions of 21.5 inches x 15.2 inches x 11.2 inches and a weight of 24.0 Pounds.
Segway Navimow i210 AWD Robot Lawn Mower sits next because its listing states AWD handling for uneven or sloped ground, with automotive-grade Electronic Stability Control. Its listing states smooth and controlled mowing on demanding 45% (24°) slopes, zero-turn steering from a concentric third-wheel design that avoids lawn scraping, an adjustable cutting height from 2 to 3.6 in, and a 7.1 in cutting width. Its listing states a 5.1Ah battery, coverage of up to 2,690 ft² per charge, and on-demand drive that gives extra power only when needed. Its listing states EFLS Network RTK with one-tap auto mapping, tri-frequency Network RTK combined with vision for centimeter-level accuracy, and app control for up to 20 mowing zones with optimized paths and resume after auto-charging. Its listing states real-time GPS alerts through the app if the mower is lifted or exits designated areas. Its title states a lawn size of 0.25 Acre and notes that the Garage S ships separately, although the same title also says the mower comes with Garage S, and no warranty term is stated in its listing.
Robot Lawn Mower Cover for Segway Navimow X390 from YNCTCWX ranks above the other cover because its listing states concrete construction and fit details. Its listing states upgraded 600D high-density oxford cloth, with durability and tear resistance, and a water-resistant coating for protection against rain, snow, moisture and humidity. Its listing states an elastic hem for a snug and firm fit around the mower, a built-in handle strap for lifting and positioning, and a reflective strip for visibility in low light. Its listing states protection from dust, dirt, scratches, bird droppings and daily wear. No warranty term is stated in its listing, and it is a cover, not a mower, so it adds no mowing ability.
Robotic Lawn Mower Cover for Segway Navimow X390 from Generic ranks last because its listing states fewer concrete details and mixes in a mismatched description. Its listing states a cover for the Segway Navimow X390, with all-weather protection, a storage bag, and easy cleaning by rinsing with water and wiping dry. Its listing states that the cover keeps the mower dry under heavy rain, snow, or morning dew. Its listing states tear-proof oxford cloth with a PU coating, described as breathable, softer and not easy to tear. Its listing also describes the item in places as a zero-turn mower cover, which does not match a robot mower, and its spec table lists dimensions that do not read as a mower cover size, so those dimensions are not repeated here. No warranty term is stated in its listing.
How to choose from what is actually listed
For sloped ground, the i210 AWD listing is the only mower listing here that states a slope figure, with AWD and Electronic Stability Control. For zone control with a stated zone count, the i210 AWD listing states app control for up to 20 mowing zones. For mapping in complex lawns, the i110N listing leans on vision plus RTK, while the i210 AWD listing leans on Network RTK plus vision with one-tap auto mapping. See our RTK vs LiDAR navigation guide for how RTK navigation compares with LiDAR navigation. If you already own an X390, the covers are the only X390 items here, and the YNCTCWX cover states the clearer fit details.
Safety
Keep children, pets and bystanders out of the yard while a robot mower runs, and clear sticks, stones and other debris before mowing. Follow the slope limit in the exact mower listing, and do not run a mower on ground beyond that limit. The i210 AWD listing states GPS alerts if the mower is lifted or leaves its designated areas, which helps you notice a mower that has moved. The i110N listing states obstacle avoidance for common garden objects, but that does not replace clearing the lawn before mowing. See our robotic mower safety around kids and pets guide for more on keeping the yard clear.
FAQ: mowing large lots
Can I compare the X390 and X450 from these listings?
No. Neither mower listing is among the listings here, so a direct comparison of those mowers cannot be drawn from them. Use the listed Navimow mowers to learn how mapping, obstacle avoidance and slope handling are described, and look for a mower listing for the exact model before deciding.
Which listed mower handles sloped ground?
The i210 AWD listing states AWD handling for uneven or sloped ground, with Electronic Stability Control, and it states mowing on demanding 45% (24°) slopes. No slope figure is stated in the i110N bullets, so do not assume the same slope handling for that model.
How does the i110N map a lawn without wires?
The i110N listing states wire-free setup with virtual boundaries mapped from a smartphone, plus AI-assisted mapping that identifies lawn edges during mapping. Its listing states EFLS 2.0 with RTK positioning enhanced by vision sensors, for stable, centimeter-level navigation accuracy.
Do the listed covers fit an X390?
The YNCTCWX cover is listed for the X390, and its listing states 600D oxford cloth, an elastic hem and a reflective strip. The Generic cover is also listed for the X390, and its listing states a storage bag and easy cleaning by rinsing with water. Both are covers only, so neither adds mowing ability.
What should I clear before a robot mower runs?
Clear sticks, stones and other debris from the lawn, and keep children, pets and bystanders out of the yard while the mower runs. Follow the slope limit in the exact mower listing, and do not run the mower on ground beyond that limit.
