Description
With the A3, Dreame has converted the series to all-wheel drive and designed it for areas where the robot works almost continuously. The cutting deck was newly engineered in the process—mowing discs from older Dreame models do not fit here. This disc is made for A3 AWD 2000 and A3 AWD 3500 PRO, with pre-assembled stainless steel blades.
What continuous operation does to the blades
An A3 AWD 3500 PRO is not built for weekend use. On properties of this size, it sets off several times a day and works through zones one after another—over a season, that adds up to a runtime that smaller devices can never reach.
For the cutting edges, it’s not the area that matters, but the number of meters they pull through the grass. That’s exactly why blades on large robots wear out earlier, even though the grass is the same.
The all-wheel drive adds to it: The A3 keeps going even where a two-wheel mower gets stuck—through damp hollows, over soft ground, along the edges of slopes. Each of these passages costs sharpness.
Compatible A3 models
A2 or A3—where is the line?
Dreame quickly expanded the A series, and the names differ only by one digit. But at the mowing deck, there’s a real break between A2 and A3:
Replacement on the A3
- Switch the device off and remove it from the charging station.
- Put on gloves and lay the robot on its side.
- Remove dirt and grass felt—on the all-wheel drive, more collects under the chassis than on two-wheel mowers.
- Loosen the old mowing disc, fit the new one, and tighten the screws crosswise.
- Tap the blades individually: Each one must be able to rotate freely around its screw.
Tightening crosswise is more important here than on smaller devices. The A3 operates with higher torque, and a mowing disc that sits unevenly transfers every imbalance directly to the mounting.

6, 7, or 9 blades on the A3
On large areas, the number of blades matters less for appearance than for service life. The more cutting edges share the same work, the finer the cut—and the sooner the next blade change.
6 blades – the long-running option
Matches the factory configuration and is the most durable choice for large properties: Six strong cutting edges carry more material and last longer, especially when the robot drives through taller or damp grass.
In addition, there is a cover here over the center of the mowing disc, which is not available with 7 and 9 blades. On the A3 with all-wheel drive, this is a practical advantage: On soft ground, the chassis pushes soil and clippings under the device, and without a cover, this material collects around the blade mounting.
For properties where the robot works many hours every day, this is the easiest combination to maintain.
7 blades – fine results without a big extra cost in wear
One more cutting edge for a noticeably more even cutting pattern. On well-maintained lawns and with regular passes, this is the sensible middle ground.
Especially on uneven terrain, this pays off, because the A3 drives with greater overlap there and every blade of grass is hit multiple times anyway.
Without center cover: uncritical on dry, firm ground – on soft surfaces, the 6-blade disc requires less maintenance.
9 blades – for neatly kept ornamental areas
The densest blade setup is suitable for properties where the A3 runs every day and only trims the tips. The cutting pattern is very even, and individual blades that remain standing disappear.
On large natural areas with vigorous growth, however, it’s not the first choice – nine narrow cutting edges wear out faster under this level of stress than they gain in fineness.
Also without coverage over the middle. With daily operation on short grass, this hardly matters.
When it’s time to replace the set
Buy blades individually
On areas of this size, the blades are what give way first—the disc stays. If you take the 60-blade replacement set with screws along as well, you can switch them out right in the middle of the season instead of waiting for a delivery.
