The Segway Navimow i105 is the cheapest Navimow at $799, a wire free robot mower for very small, gentle lawns up to 0.125 acre. It is fine for a tiny, flat yard, but its 30 percent slope limit and rear wheel drive mean most buyers should spend about $250 more on the i210 AWD.
What the Segway Navimow i105 is

Hands on testing is in progress, and we will update this review with our results.
What it does well
Price is the main attraction. At $799 on the Navimow store, it is the lowest priced Navimow, below the $849 i206 AWD and the $1,049 i210 AWD Navimow store ↗. Its spec page lists a $999 MSRP, so the current price is a sizable discount Navimow i Series specs ↗.
It is quiet and weatherproof. Segway rates it at 58 dB(A) and IP66 Navimow i Series specs ↗. That should let it run on a schedule without bothering neighbors and sit outside in the rain.
Theft protection is good for an entry model. It includes GPS theft tracking, a PIN code, an anti theft alarm and a lifted mower alarm Navimow i Series specs ↗. It connects over Bluetooth and Wi-Fi, works with Alexa and Google Home, and can add 4G with the optional Navimow Access+ module Navimow i Series specs ↗.
It is also small and light. It weighs 24 pounds and measures 21.4 by 15.1 by 11.2 inches, which helps in tight spaces Navimow i Series specs ↗.
Where it falls short
The rated area is tiny. At 0.125 acre, it covers half of what the i210 AWD is rated for Navimow store ↗. It mows 60 to 100 square meters an hour, and a full charge gives 60 minutes of mowing followed by 90 minutes of charging Navimow i Series specs ↗.
Slopes are limited. It handles a maximum slope of 30 percent, and only 10 percent at the boundary Navimow i Series specs ↗. It is rear wheel drive Navimow i Series specs ↗. Our budget pick, the i210 AWD, is rated for 45 percent slopes and adds a driven third wheel for traction i210 AWD specs ↗.
The cut is narrow. The deck is 7.1 inches wide with three blades, and cutting height adjusts manually from 2 to 3.6 inches Navimow i Series specs ↗. The battery is a small 2.55Ah pack Navimow i Series specs ↗.
Finally, there is little independent testing to draw on. The i105 was not part of Bob Vila's 2026 robot mower test, which covered larger models Bob Vila test ↗.
