Our take
Dreame A2 Robotic Mower
Excellent navigation technology when the unit is healthy, but owner reports of LiDAR failures, slow mowing and patchy support make this a risky buy for larger lawns.
Owners coming from the A1 praise Dreame's LiDAR navigation and the app when everything is working.
LiDAR faults, slow coverage, missed areas, battery concerns and weak parts/support availability are the main negatives.
Lawns suited to omnisense 2.0 3d perception.

What owners and reviewers say
Tests praise straightforward setup and a tidy cut, while disagreeing about edge finishing and obstacle detection. Owner reports add a separate concern about LiDAR failures and slow coverage, although the available accounts cannot establish how common those problems are.
A tidy lawn with little setup work
Les Numériques found the wire-free installation, accurate mapping and approachable app particularly helpful for newcomers. In its test the A2 worked quietly and followed controlled routes, leaving a generally even finish. Its customisation options were useful without making everyday operation difficult.
[2]How much edging remains?
Notebookcheck found that the moving deck reduced the uncut strip, sometimes finishing flush borders completely, while enclosed corners remained problematic. Les Numériques was less impressed with EdgeMaster. Border shape and height therefore remain important: a movable deck cannot reach every boundary.
[1][2]Small objects need realistic expectations
With firmware 4.3.6_0186 and sensitive settings, Notebookcheck avoided most test objects, including a dummy hedgehog and short hose, but hit a tennis ball. Taller grass could be mistaken for an obstruction. Les Numériques also found detection inconsistent. The assistance does not establish dependable recognition of everything left outside.
[1][2]Large lawns and long-term ownership
Les Numériques considered endurance a limitation for very large areas despite the premium price. Notebookcheck found better grip than on the A1, but that is a comparison within Dreame’s range, not proof that the A2 will match an AWD mower on wet slopes. The reviewed evidence does not establish a multi-season failure rate or typical support turnaround.
[1][2]Owners add repair and coverage concerns
In a model discussion, two explicitly identified A2 owners described LiDAR repairs, including one repeat failure. Another account reported slow coverage on roughly 1,100m² because of the balance between mowing and charging. A dissatisfied owner later posted that a replacement A2 had restored their satisfaction, after the original was judged unrepairable. These experiences add meaningful caution beyond short review tests, but the discussion is a self-selected sample and supplies no failure rate. Praise for an A1 elsewhere in the thread is not treated as A2 ownership.
