Should I buy the Ecovacs GOAT O600 RTK or the O800 RTK?

For most lawns over about 450 m², or any garden with toys and furniture on the grass, the O800 is the safer choice. The O600 makes sense only for smaller, tidy lawns where the lower price matters most. Both sit in the Ecovacs GOAT O RTK (O600 RTK / O800 RTK) family, share the same body and RTK station, and differ in four ways.

• Rated area: 600 m² for the O600 against 800 m² for the O800, according to Ecovacs.
• Cut width: 190 mm on the O600 and 220 mm on the O800, so the larger model covers more ground per pass.
• Battery: 45 Wh against 72 Wh. The O600 charges faster (Ecovacs quotes about 55 minutes, while its O800 figures conflict), but it stores far less energy.
• Obstacle detection: the O600 relies on an AI camera alone. The O800 adds a 3D ToF sensor, which measures distance and should help with low or awkwardly shaped obstacles.

The rest is identical on paper: a 45% slope rating, heights from 30 mm to 80 mm, a 70 cm minimum passage and the same warranty.

Current prices are £449 for the O600 and £699 for the O800, and the O800 has been listed well below its RRP, which narrows the gap. One more point: Ecovacs UK names only the O800 as compatible with its RTK extension cable, power supply and wall mount, so check before you plan a tricky station position for an O600.
