Segway Navimow i208 LiDAR Robot Lawn Mower with Garage M (800 m2 rated) vs Segway Navimow i205 AWD Robot Lawn Mower with Garage S (500 m2 rated)

Pros

• + Solid-state LiDAR plus vision needs no boundary wire, no RTK mast and no mobile signal, so trees and shade do not break it
• + Rated by Segway for 800 m2 and for 45% (24 degree) slopes on off-road wheels
• + IP66 sealing, built-in 4G tracking and a cutting height reaching 70 mm for a shaggier lawn
• + Up to a three-year warranty published on Navimow's UK site, with a UK operation behind it

Cons

• − T3's published review reports an involved setup and automatic mapping that does not always work first time
• − 265 m2 per charge against an 800 m2 rating means several runs to cover the lawn it is sold for
• − The Garage M is included but ships separately from the mower
• − No dedicated edge-cutting disc, so a strimmer is still part of the job

Pros

• + All-wheel drive with electronic stability control, rated for 45% (24 degree) slopes
• + Zero-turn concentric third wheel turns without scuffing the lawn, and the third motor engages only when needed
• + One-tap auto mapping over tri-frequency network RTK and vision, with no mast to site and up to 20 zones
• + Up to a three-year warranty published on Navimow UK, with 4.6 stars from 284 Amazon UK ratings

Cons

• − Network RTK depends on a mobile connection for precise positioning - a weak-signal garden falls back on cameras
• − Rated for 500 m2 but only 125 m2 per charge, so a full lawn takes several runs
• − Navimow does not publish an IP rating for this model on the Amazon UK listing
• − The Garage S is included but ships separately from the mower
