For fifteen years the robotic mower was a puck: a low, wheeled disc that could cut grass and do nothing else. This month at IFA 2026 in Berlin, five manufacturers — Mammotion, Eufy, Dreame, MOVA and Sunseeker — showed mowers with arms, and a sixth, ANTHBOT, picked up an IFA innovation award for one. The industry has quietly crossed a line. The question is no longer whether a robot can find its way around your lawn; it is whether it can reach out and change what it finds there.
This is an analysis piece. It connects announcements AI Mower News has already reported individually and adds what independent reporters saw on the show floor. Where a figure comes from a company rather than a hands-on observation, we say so.
Stage one: arms for the edge
The edge — the strip of grass along a wall, fence or path that a round chassis physically cannot reach — has been the single most common complaint about robotic mowers since the category began. In 2026 every serious maker attacked it with hardware that moves:
- Dreame A4 AWD Pro (EdgeMaster 4.0) — a sensor-guided swing arm that pushes the cutting disc outward at boundaries for what Dreame claims is a 0 cm cut. Two models (3,500 m² and 5,000 m²), from €2,999, “selected markets” in the first half of 2027. Gizmodo saw the arm work at the show. Notably, the EdgeMaster 2.0 on this spring’s A3 AWD Pro was a sliding blade deck, not an arm — the arm is new this September. Our earlier report.
- Mammotion LUBA 4 AWD — an optional rear-mounted Edge-Trimming Module that swings a trimmer line along walls, fences and beds, described on-site by Gizmodo and Maison et Domotique. Pre-orders open in the fourth quarter of 2026 for the 3000F and 6000F variants; no price yet. Our IFA coverage.
- Eufy Robot Lawn Mower S2 Max — Anker’s first in-house mower, with a trimming arm that extends from the side. €3,999, Europe in May 2027, and — per Gizmodo — no U.S. plan at present.
- MOVA UltraTrim 4.0 — an “adaptive robotic edging arm” with 4, 5 and 6 cm heights that retracts when it meets an obstacle, per MOVA’s IFA materials.
- ANTHBOT R7 Series — an “EdgeEase” trimming arm, named an IFA Innovation Award 2026 honoree; no price or reach published.
Five companies, one problem, one answer. That is how you know a category has matured: the differentiator has moved from “can it navigate” — RTK, vision and LiDAR are now table stakes — to “what can it physically do.”
Stage two: arms that change the environment
The more consequential shift is the second one. Two companies showed arms that do not cut anything; they move things.
MOVA’s AstraX, billed as the first mower with a multifunctional robotic arm, uses interchangeable tool heads: a two-finger gripper that, when the mower’s vision system flags an obstacle, removes it before mowing resumes; the same gripper picking low-hanging fruit; and a nozzle head for timed watering. GadgetGuy watched the demonstration and noted MOVA “didn’t confirm any launch details” — so treat AstraX as a working concept, not a product. Our report from the launch.
Sunseeker’s S7 LiDAR Ultra AWD 3000 is closer to a shipping product. Sunseeker’s own announcement confirms an “Extension Hub” that accepts accessories, including its EdgeZero trimmer head and a robotic arm. The detail everyone is repeating — that the arm can clear objects up to 2 kg (4.4 lb) — does not appear in Sunseeker’s materials; it comes from CEO Ma in an interview with How-To Geek, along with a target of roughly €500 for the arm, about €2,500 for the mower, and a February 2027 date. Android Headlines saw the arm pick up balls and children’s and dog toys at IFA, and described it as very slow and limited to small items. In other words: real, demonstrated, early.
Why now
Three things converged. First, perception got good enough: the camera-plus-LiDAR stacks that arrived for navigation can now classify a toy, a hose and a hedgehog, and an arm is only useful if the robot knows what it is reaching for. Second, the navigation race ended in a draw — once everyone offers wire-free RTK and vision, the edge and the obstacle are the last visible differences between a €2,000 mower and a €4,000 one. Third, the Chinese consumer-robotics companies that now dominate this market (Dreame, MOVA, Eufy/Anker, Mammotion) already build manipulators for other product lines and can bolt them on faster than the legacy turf brands.
What is real, and when
| Product | What the arm does | Status | Price / date (company claims) |
|---|---|---|---|
| Dreame A4 AWD Pro | Swings cutting disc to the boundary | Demonstrated at IFA | From €2,999; H1 2027, selected markets |
| Mammotion LUBA 4 AWD | Optional rear trimmer-line module | Demonstrated at IFA | Module price TBA; pre-orders Q4 2026 |
| Eufy S2 Max | Side-extending trimming arm | Demonstrated at IFA | €3,999; Europe May 2027; no U.S. plan |
| ANTHBOT R7 | EdgeEase trimming arm | Award honoree; details thin | Not published |
| MOVA AstraX | Gripper / fruit picking / watering heads | Concept demo | No launch details |
| Sunseeker S7 LiDAR Ultra AWD 3000 | Extension-hub arm; clears small objects | Demonstrated at IFA (slow, small items) | ~€2,500 mower + ~€500 arm; Feb 2027 (per CEO interview) |
Nothing on this list is on sale today. The earliest is Mammotion’s module in late 2026; most are first-half-2027 European launches, and several makers list no U.S. date at all.
What This Means for You
If you are shopping this autumn, do not pay a premium for an arm that is a 2027 promise — buy for cut quality, navigation and support, and treat edge-trimming as a bonus if it ships. If you can wait until next summer, the picture is genuinely different: for the first time, a mower may finish the lawn rather than most of it.
The bigger story is for the whole category. A mower that can clear a toy from its path is a robot that can, in principle, move a hose, tidy a fallen branch or pick fruit. Every company above knows that, which is why the arm demos at IFA looked less like accessories and more like the first draft of the next product.
FAQ
- ### Which robot mowers have arms in 2026?
- Announced at IFA 2026: Dreame A4 AWD Pro (EdgeMaster 4.0 swing arm), Mammotion LUBA 4 AWD (optional Edge-Trimming Module), Eufy S2 Max (side trimming arm), MOVA’s UltraTrim 4.0 edging arm and AstraX gripper arm, and Sunseeker’s S7 LiDAR Ultra AWD 3000 (extension-hub arm). ANTHBOT’s R7 has an “EdgeEase” trimming arm.
- ### Can any robot mower pick up objects yet?
- Two were demonstrated: MOVA’s AstraX (a concept with no launch date) and Sunseeker’s S7 arm, which reporters saw lift toys at IFA. Sunseeker’s CEO has quoted a 2 kg limit; that figure is not yet in the company’s published specifications.
- ### When can I buy one?
- Per the makers: Mammotion’s module pre-orders in Q4 2026; Dreame and Sunseeker in the first half of 2027; Eufy in Europe in May 2027. Several have not announced U.S. availability.
- ### Are the edge arms just string trimmers?
- Mostly yes. Mammotion’s and Eufy’s use trimmer line; Dreame’s instead swings the mower’s own cutting disc outward. All rely on side sensors or cameras to follow the boundary.
