The same day Mammotion and Segway Navimow each unveiled their own fix for robot-mower edge cutting at IFA 2026, Dreame joined them with its own mechanism, the A4 AWD Pro. Notebookcheck’s own writeup places Dreame after Anthbot, Navimow and Anker on this exact promise this week. What sets Dreame’s entry apart is a number none of the others have shared yet: a starting price, €2,999.
EdgeMaster 4.0: an extendable arm, not a separate attachment
Dreame’s system, EdgeMaster 4.0, is a side-mounted arm that swings the cutting deck beyond the wheel track when the mower approaches a boundary. ComputerBase, which says it received this information from Dreame under NDA, describes the mechanism this way, and adds a caveat worth keeping: even with the 0 cm claim, Dreame says the mower always keeps a safety distance from obstacles and walls rather than actually touching them. Gizmodo separately quotes Dreame’s claim of “0 cm edge cutting,” based on the company’s own lab testing; no independent test of the real-world result exists yet.
Navigation runs on OmniSense 4.0: 360-degree 3D LiDAR for mapping, dual-frequency RTK for open areas, and binocular AI cameras for obstacle recognition. Per ComputerBase, the same time-of-flight sensor that guides the arm precisely along the boundary also detects drop-offs so the mower itself does not fall; a separate infrared sensor detects people and pets near the boundary to keep the arm from reaching them. Gizmodo also flags a hardware change from Dreame’s current lineup: swiveling, servo-driven front caster wheels in place of omnidirectional ones, a system ComputerBase and Notebookcheck both call AeroTurn, aimed at tighter turns with less turf damage. Gizmodo’s own IFA writeup recalls testing the current A3 AWD Pro and finding it “had a bad habit of tearing up bits of my lawn, leaving bald patches in the grass behind,” which is the complaint AeroTurn is meant to fix.
What the A4 AWD Pro claims
ComputerBase and Notebookcheck both got their figures directly from Dreame (Notebookcheck credits “Dreame” as its sole source), so treat these as the company’s own claims, not independent measurements. On slope, ComputerBase gives the fuller picture: the drivetrain itself is rated to climb 42-degree grades, while mowing specifically is rated at 80 percent (38.7 degrees) driving straight up a slope and 70 percent (35 degrees) moving across one; Notebookcheck’s single figure, 90 percent (42 degrees), is the same drivetrain rating without that mowing-specific breakdown. Both outlets agree the mower crosses obstacles up to 7 cm high and potholes up to 10 cm deep and 15 cm wide. Prices for the lineup start at €2,999, which ComputerBase and Notebookcheck both describe as provisional and not tied to either the 3,500 or 5,000 square meter configuration specifically. Dreame is targeting a worldwide launch in the first half of 2027, though neither a US price nor a US launch date has been announced.
Gizmodo, in that same IFA writeup, mentions a 65 percent domestic-parts threshold tied to the FCC rule SpecsLib covered in July, which blocks new authorizations for foreign-made mowers; SpecsLib’s own reporting already flagged that specific figure as an unconfirmed secondary-source claim absent from the FCC’s public notices, so treat it the same way here.
What to buy if you are not waiting until 2027
Dreame’s own current A3 AWD Pro line is the same-brand comparison while the A4 AWD Pro has no confirmed US price or launch date. The A3 AWD Pro 3500 (about €2,199 or $2,700 today) and the larger A3 AWD Pro 5000 (about €2,799 or $3,500) both ship today in the US and Europe, with the caster-wheel turf damage noted above still a live complaint on that generation. Dreame’s own under-3-cm edge claim for this generation is reproduced by heise and PC-WELT without their own measurement, not independently confirmed; on the 5000 specifically, Labo Maison measured closer to 5 cm along hedges and walls. Neither current model has the swing arm the A4 AWD Pro is built around, so hand-trimming an occasional strip is still likely. If the A4 AWD Pro’s promise is a mower you never touch a strimmer with again, the honest comparison for now is a machine you can already own, turf complaint and all, at a lower price than Dreame’s starting figure for the one arriving in 2027.
