Does the LawnMaster OcuMow 16 go back to a charging station by itself?

No. The LawnMaster OcuMow 16 has no docking station at all. LawnMaster sells it as a "drop and mow" robot: you carry it onto the lawn, switch it on, and it mows on its own until the battery runs flat. Then you take the battery out and charge it on the supplied charger, which LawnMaster says takes about an hour.

That makes it closer to a self-driving cordless mower than a typical robot. You don't have to push it, but you do have to be there to start each session, so it can't keep the lawn trimmed on a schedule while you're away. LawnMaster quotes up to four hours' mowing per 4.0 Ah battery, and rates it for 150–300 m² depending on whether you buy one battery or two. The two-battery kit gives you a second run after a manual swap, not a longer run by itself.

There are advantages to having no dock. Nothing needs installing, there's no wire or app, and because you bring it in after use it isn't sitting in the garden for a thief. It also shares its MX 24V battery with LawnMaster's other tools.

If you want a mower that goes out and returns on its own, look at the LawnMaster OcuMow AMB16 or LawnMaster OcuMow 18, which both have auto-charging docks. Our robot vs cordless guide explains the trade-off.
