Can it mow a front and back yard that are not connected?

Yes. If the robot can drive between them, Dreame has you map each area and draw a path connecting them; the blades stay off on the path. If a barrier separates them, the robot supports two individual maps, and Dreame recommends a separate charging station for each, because mapping starts from the station.

Does it need Wi-Fi in the yard?

Not for control. Dreame says the robot has a pre-installed 4G Link module that keeps it connected to the app without Wi-Fi. The product listing includes 1 year of 4G data.

LiDAR + vision, ~1/4 acre

Dreame A3 AWD 1000 Robot Lawn Mower (Wire-Free, No RTK)

A four-wheel-drive robot mower for lawns up to a quarter acre that maps and navigates with 360° 3D LiDAR and stereo cameras, so there is no boundary wire and no RTK antenna to install.

What's good

Nothing to install in the yard: no perimeter wire to bury and no RTK antenna to mount and power
LiDAR does not depend on a clear view of the sky, so tree cover and tall walls that weaken satellite positioning are not its weak spot
80% slope rating with true four-wheel drive, the steepest of the quarter-acre picks here
Cutting height is changed from the app, not a knob on the mower

What's not

No RTK at all: positioning rests on LiDAR recognizing the yard's fixed features (Dreame states a 164 ft detection range), so a wide open lawn with little structure nearby is worth asking about before you buy
7.9 in cutting width is narrow, which is why it is rated for a quarter acre
Two separate lawns need a second charging station: Dreame says mapping starts from the station

Our verdict

The pick for a small, awkward yard: slopes, trees, a side path. Skipping RTK removes the most annoying part of wire-free setup (siting an antenna with a clear sky view) and the weakness that comes with it under trees. The trade is that it navigates by what it sees, so it suits a yard bounded by a house, fences and plantings better than an open field. Size it honestly: a quarter acre is the rated lawn area, not the lot.

Frequently asked questions

No. Dreame says it starts mapping on first start-up without boundary wires, beacons, GPS stakes or antennas, using 360° 3D LiDAR and binocular AI vision to find the lawn's edges. You can also drive the boundary by remote control in the Dreamehome app and edit the map afterwards.
