Description
Dreame has expanded the A series in quick succession—A1, A1 Pro, A2, and most recently A3. When choosing replacement parts, there is only one key distinction: A1, A1 Pro and A2 share the same disc mount, while the A3 AWD does not. This disc fits the first three models and is supplied with pre-assembled stainless steel blades.
Three models, no adapter
Between the A1 and A2, Dreame has worked on navigation and equipment, but left the mowing unit unchanged. If you switched from an A1 to an A2, you can continue to use your existing replacement disc.
The Pro version of the A1 also doesn’t change anything. It differs in the sensors, not in how the disc sits.
That makes stocking easy: One disc type covers half of the A series, and the blades are interchangeable between the devices.

A1, A2, or A3 – which one is in the garden?
“A1 vs A2 vs A3” is one of the most searched questions about Dreame lawn mowing robots. For the disc, it all comes down to one point:
Replacement on the Dreame
- Switch off the robot and remove it from the charging station.
- Put on gloves and place the device on its side.
- Remove clippings around the mowing deck so the new disc sits flat.
- Loosen the old disc, attach the new one, and tighten the screws evenly.
- Tap each blade once—it must be able to rotate freely around its screw.
The final step determines the service life. A blade that is stuck in place cannot move out of the way when it hits a stone and transfers the impact directly to the mowing deck.

6, 7 or 9 blades on the Dreame
All three configurations fit on the same mount. The number of blades does not change the motor power, but how finely the cut is made—and how long each cutting edge lasts.
6 blades – as from the factory, with hub protection
The configuration that matches the original. The robot drives as usual, and the battery life remains unchanged—ideal if you simply want to replace the worn mowing disc.
This variant is the only one that has protection over the hub; it is missing with 7 and 9 blades. With the Dreame, this is especially worthwhile in gardens with deciduous trees: damp leaves and grass clippings otherwise settle exactly where the blades engage, and slow them down.
Anyone who runs the robot on a schedule and rarely looks under the chassis will be the most carefree with this option.
7 blades – for neatly kept lawns
One extra cutting edge provides additional cuts per revolution. On well-maintained areas with short mowing intervals, the result is therefore more uniform.
A good compromise for everyone who values a clean look without significantly increasing wear.
No hub protection: In gardens without leaves and with dry grass, this doesn’t matter.
9 blades – for daily operation
Nine cutting blades produce the finest cut pattern—provided the robot runs often and only trims a little. Then even individual blades of grass that remain standing will disappear.
With longer breaks between mowing sessions, the advantage flips: the same amount of work is spread across more edges, which therefore become dull earlier.
Also without hub protection—when mowing daily on short grass, little collects under the device.
Signs that it’s time to replace
Buy blades individually
Because with Dreame the entire set is always replaced, it’s worth keeping a supply at home. The 60-blade replacement set including screws covers multiple replacements—so the next set is ready before the cutting performance declines.
