Our verdict
The Einhell flagship cordless. Self-propelled, rear-roller, 47cm cut at £600 with batteries. The Power X-Change ecosystem is the actual value — if you own Einhell tools, the batteries cross over cleanly. Otherwise the EGO XP series is the better cordless for the money.

Buying second-hand
£200–340 used. Test BOTH 18V batteries individually — mismatched packs (one new, one tired) give 10 minutes of runtime. PXC batteries hold value at £40 each used. Self-propel drive belt is the wear part — check it doesn't slip on an incline.
