TerraMow drops the wire and the RTK base. The bill comes due on the first map.

9to5mac published a review of the TerraMow V1000 on August 14, 2026, describing a robot mower that builds its map with three cameras and navigates without a buried perimeter wire or a separate RTK antenna ^[1][18]. The comparison unit in the same review, the Anthbot M9, does the same job with an RTK reference station plus a setup process in which the owner manually steers the mower around the perimeter from an iPhone ^[2]. Removing both means the V1000 drops two steps that the Anthbot workflow requires ^[19].

The reviewer is direct about the cost of that: automatic mapping took a lot longer to produce the initial map ^[3]. The argument for eating that delay is that the delay is unattended. According to the reviewer, the payoff showed up when he had his mother, in another state, set up and use the V1000 with no help from him, and she reported that everything worked fine ^[13]; he was less confident she would have had the patience to drive a robot around a full perimeter and hand-mark exclusion zones first ^[12].

Vision also fails differently than positioning hardware fails. With no fence or physical divider between the reviewer's front lawn and his neighbor's, the mower initially annexed part of the neighbor's yard into the map ^[4]. That was fixable in the app by marking the section off-limits, but the reviewer's conclusion is the operative one: lawns without distinct visual boundaries may need extra attention during initial mapping ^[4][5]. An RTK base does not care whether your grass looks like your neighbor's grass. A camera does.

The second structural constraint is light. Because navigation depends on the cameras, the V1000 needs daylight to work reliably, which makes daytime scheduling more important ^[6]. The Anthbot, by contrast, can mow after sunset using a headlight and run quietly enough to forget about ^[15]. So the vision-only design does not just move cost off the bill of materials; it narrows the operating window and pushes the machine into the hours when people are home and awake. The V1000 already cuts lower and makes more noise than the Anthbot, per the reviewer ^[16].

The cameras do earn something back beyond setup. The app can show a live view of what the mower sees while it works, which the Anthbot does not offer ^[14], and the reviewer rates the app's one-handed joystick mode, alongside conventional left and right controls, as the feature every competitor should copy ^[10]. Otherwise the two apps overlap on scheduling, mowing behavior, zones, exclusion areas and remote steering ^[9]. The V1000 is the larger machine, feels substantial, and ships with a garage over the charging dock that Anthbot sells separately ^[7]. Over weeks of testing it did not require the reviewer to take over mowing himself ^[8].

Two things to watch. First, the adaptive map: the mower continuously revises its map from what it sees, and the reviewer flags that same intelligence as something that can occasionally work against it, with post-job saving of those changes as the friction point ^[17]. Second, price. The review does not state what either machine costs ^[11], and the whole cheap-cameras-instead-of-hardware case rests on a number nobody has published here.
