Description
With Ecovacs, model names regularly lead to incorrect orders. GOAT O500 and GOAT A1600 sound like they belong to the same family, but they don’t: the O and G1 series share a mowing deck, while the newer A series has a completely different mounting. This mowing disc fits the older family—with 6, 7, or 9 blades, delivered pre-assembled.
A spare part for five GOAT models
Ecovacs uses the same disc mount in the O series (O500, O800, O1200) and in the G1 series (G1-800, G1-2000). This disc is made exactly for that: it fits without an adapter, without drilling, and without modification—remove, attach, and tighten.
This makes storing spare parts easier. If you have two different GOAT models in use—e.g., an O500 in the front garden and a G1-2000 behind the house—you only need one type of mowing disc as a spare. The blades are also identical and interchangeable with each other.
The only difference between the variants is the number of blades: 6 for the factory standard, 7 for a finer cutting pattern, 9 for grass kept short. All three are supplied with pre-assembled blades.
Compatible GOAT models
O or A – how to identify your series
The fastest way is via the type label on the underside. It contains the full designation, and the letter directly before the number determines it: O or G1 indicate the older family, A the newer RTK series.
The second feature is navigation. O and G1 devices use cameras and a system without a boundary wire, which Ecovacs called TrueMapping at the time. The A series uses an RTK antenna that is placed separately in the garden.
If you have set up an antenna, you very likely have an A model and need the other disc. When in doubt, check the packaging or the invoice—the complete model designation is always listed there.

6, 7 or 9 blades – what actually changes
More blades don’t mean more cutting power, but more cuts per revolution. The motor works the same; the grass is just hit more often. All three versions fit the same five GOAT models.
6 blades – factory standard with hub cover
The configuration with which Ecovacs delivers the GOAT. If you simply want to replace the worn original cutting disc, this is the right choice: same running behavior, same battery life, no adjustment needed.
This version additionally has a cover over the hub – the 7- and 9-blade discs don’t. It closes off the area where, with the GOAT, clippings tend to collect: The robot uses a mowing deck that sits relatively low, and whatever once gets caught around the blade mount slows the blade down. With the cover, this spot stays clear.
For normally maintained lawn with mowing intervals of two to three days, this is the most unobtrusive option.
7 blades – finer cutting pattern
One blade more than from the factory, with practically unchanged wear. The grass is hit more often along the same path, and the cutting edges end up shorter.
The usual compromise for well-kept ornamental lawns: visibly cleaner than the 6-blade version, without the blades dulling noticeably faster.
One difference remains: we only provide the hub cover on the 6-blade disc. With the GOAT and its deep-mounted mowing deck, that’s the point where damp grass is most likely to get stuck.
9 blades – for neatly kept lawn
The densest setup is worth it when the lawn is kept short and the robot drives frequently—often daily. The cutting pattern becomes more even, and individual blades that are left standing disappear.
The price for that: the individual blades dull a bit faster because the work is spread across more cuts. If you use this variant, it makes sense to get a set of blades as well.
Swap in five minutes
- Switch off the GOAT and remove it from the charging station.
- Put on gloves and turn the device over.
- Remove lawn felt from the underside—this prevents imbalance later.
- Loosen the old disc, attach the new one, and tighten it firmly.
- Rotate it by hand and check that it runs freely.
A suitable screwdriver is enough. What matters is only that the disc sits cleanly and nothing is jammed—an abrasive disc puts strain on the mowing motor’s bearing over time.
Recognizing wear
Buy blades individually
The blades are a wear part, the disc is not. For the next replacement, a new set of blades is usually enough—the 60er replacement blades set incl. screws fits all GOAT discs from the O and G1 series and lasts for several seasons.
