The lawn suddenly no longer looks neatly cut, even though the Dreame mowing robot is following its schedule: the blades are frayed, and certain areas look downright plucked— or, when cleaning, a blade is suddenly missing. That’s exactly when it’s not enough to just order any blade set. In the workshop, we repeatedly see: it’s not only the blade itself that matters, but also the screw, the holder, and the condition of the cutting disc. If you check properly here, you avoid vibrations, lost metal parts in the lawn, and unnecessarily damaged mowing discs.
This practical guide is aimed at owners of a Dreame A1, A1 Pro, A2, or A3 AWD. The focus is deliberately on the problems many users actually report: jammed blades, stiff blade(s), uncertain third-party screws, missing holders, and buzzing mowing discs after a blade change.
Changing Dreame blades: These five wear signs really matter
A fixed replacement date according to the calendar is convenient, but rarely precise. On a clean, level lawn, blades behave differently than on an area with fallen fruit, sand, small branches, or many lawn edges. That’s why, in our CUT-GUARD tests, we first assess the actual condition of the cutting system—not just the age of the blades.
1. Frayed blades of grass instead of a clean cut edge
This is the clearest sign of dull blades. Freshly cut blades should be cut off cleanly. If the tips are whitish, frayed, or uneven, the grass is more likely to be torn than cut. This is noticeable right away, especially with dense, damp, or fast-growing lawns.
2. Poor cutting performance despite unchanged settings
If neither the cutting height nor the mowing schedule has changed, but the lawn increasingly looks unsteady, it’s worth taking a look underneath the robot. In forums, people frequently complain about the Dreame A1 that the blades become stiff early due to grass clippings and dirt. Then even a blade that is still sharp enough may not be able to do its job properly.
3. Blade does not swivel freely
The individual blade must be able to move slightly at its mounting. If it’s stuck due to dried grass clippings, sits at an angle, or is blocked by a bent holder, cleaning is the first step. If it remains stiff afterward, the blade—including its mounting—must be replaced.
4. Nicks, rust, bending, or missing blade
A bent, heavily notched, or rusty blade is not used again. If a blade is missing entirely, stop mowing immediately: don’t continue, and don’t “wait until the weekend.” Search the affected area systematically, because a loose blade in the lawn is a safety risk for children, animals, shoes, and tires.
5. Buzzing, vibrations, or grinding noises
Unusual noises after a change do not automatically indicate engine damage. More often, a blade is not moving freely, a holder is missing, a screw is protruding, or the disc no longer runs true due to damage. The cause must be identified before the next mowing operation.
Practical rule of thumb: It’s not the calendar that determines new Dreame blades, but the cutting pattern, free movement, and complete fastening. A missing blade always means: stop, search, check.
How often do Dreame blades need to be replaced?
As a practical guideline, we recommend a visual inspection every two to four weeks during the main season and a replacement as soon as one of the five signs of wear becomes visible. Many users replace their blades about monthly, especially with intensive mowing. This is a sensible routine, but not a fixed requirement for every garden.
Anyone mowing a small, clean ornamental lawn can often work much longer with a single set. On properties with leaves, cones, branches, gravel from the path, or molehills, blades often become dull earlier. Also, wet grass collects more readily around the cutting disc and can impair the pivoting mechanism.
| Practical case | Meaningful checks | Typical measure |
|---|---|---|
| Clean lawn, regular mowing | Every 3–4 weeks | Clean the blades; if the edges are dull, replace completely |
| Strong growth in spring | Every 2 weeks | Check the cut pattern and free pivoting movement |
| Leaves, branches, sand, or fallen fruit | Quickly check before every use | Clear the area; replace damaged blades immediately |
| Buzzing or vibration after changing | Immediately | Switch off the robot and check the mowing disc/blade plate and mounting |
Our workshop tip: Before the season starts, build up a small supply. Instead of running individual blades until they are completely unusable, a full replacement with the right mounting parts is often the cleaner solution. For this scenario, complete replacement blade sets for the change are useful, because you don’t have to search for screws or holders only when the robot is already standing still.
Before the change: Secure Dreame and thoroughly inspect the cutting disc
Before loosening even a single screw, remove the robot from the charging station, switch it off, and place it securely on a soft, clean surface. If necessary, wear gloves: Even dull blades can still be sharp enough to cause cutting injuries.
The checklist for the mowing disc, holders, and screws
- Messerscheibe: Are there cracks, chips, warping, or visibly worn mounting points?
- Klingenhalter: Is each holder present, straight, and firmly seated in its intended position?
- Schrauben: Are the heads rounded, rusty, loose, or damaged?
- Freigang: Can all blades move without contact with the blade guard?
- Sauberkeit: Is compacted lawn dirt sitting under the mowing disc or in the blade mounting points?
- Rundlauf: Is there play in the mounting point or a reason for later vibrations?
Many users report that during what seems like a simple blade change, a different problem suddenly becomes visible: a cracked plastic mowing disc, a missing holder, or a part of the quick-release mechanism. This is not a minor detail. Installing a new blade on a damaged mowing disc does not solve the underlying problem.
If you have already discovered cracks, play, or damaged mounting points, you should not keep improvising. For model-specific selection, mowing discs for Dreame models are more helpful than blindly buying individual universal parts. The key point is that the mowing disc and the mounting system truly fit together.
Practical rule of thumb: When changing the blade, always check the mowing disc as well. Cracks, play, a missing holder, or a blade that rubs are reasons to repair before the next use.
Replace Dreame blades correctly: treat the blade, screw, and holder as a single unit
The most common mistake is not loosening the old blade, but carelessly reusing the mounting parts. Especially with inexpensive replacement sets, users report screws that come loose, rust, or fit poorly. That’s why we always treat the blade, screw, and holder as a unit that belongs together.
Step by step to a safe replacement
- Switch off the robot completely: The mower must not charge in the station and must not be startable via the app.
- Clean the underside: Remove grass, dirt, and threads around the cutting disc with a brush or a plastic tool. Do not “expose” a blade under dirt by reaching in with your hand.
- Loosen the old blade individually: Carefully remove the screw or holder and place it directly in a bowl. This way, no small part is lost in the grass or on the workbench.
- Check the mounting: The threads, the holder, and the contact surface must be clean and undamaged. A broken screw must not be tightened further by force.
- Align the new blade correctly: The blade must sit in the intended slot or elongated hole and be able to swing freely later.
- Use the correct fastening: Only install screws and holders that are intended for the blade and disc. Do not “make it fit” with washers, screws that are too long, or mixed parts.
- Tighten—do not overtighten: The connection should be secure, but the blade itself must remain movable. Too tight can cause the blade to jam; too loose can cause it to come off.
- Final check: Move each blade individually, check the quantity, and slowly rotate the disc by hand. Nothing should rub or catch.
With multiple blades, we generally replace the entire set. Blades that are worn to different degrees can adversely affect smooth running and produce an uneven cutting pattern. If you’re looking not only for replacement blades, but a solution that can be maintained reliably over the long term, you’ll find suitable options for regular maintenance under robust cutting disc and blade solutions.
Which replacement blades fit the Dreame A1, A1 Pro, A2 and A3 AWD?
“Fits for Dreame” is not enough as a purchase criterion. Especially for the A1, forums often discuss slot shapes, differing dimensions, and blades from other brands. This shows above all one thing: compatibility must not be guessed.
These six points must match before purchase
- Hole shape: Round holes or slots must fit exactly to the mowing disc and holder.
- Blade length: Blades that are too long can rub against the blade guard; blades that are too short change the cutting surface.
- Material thickness: This affects fit, mobility, and the distance to neighboring parts.
- Holder or screw system: A blade may look like it fits and still not be securely fastened.
- Clearance: After installation, the blade must remain free over the entire pivoting range.
- Model approval: A1, A1 Pro, A2 and A3 AWD are not automatically interchangeable across the board.
| Model | Practical note | Recommendation |
|---|---|---|
| Dreame A1 | Many user reports about clamping issues, alternative blades, and questions about mowing discs | Compare the elongated slot, dimensions, and mounting particularly carefully |
| Dreame A1 Pro | Reports of missing holders and problems when switching | Never order blades without the appropriate holder/screw parts |
| Dreame A2 | Generous supply of replacement blades and holders included in the delivery is known | Use original parts sensibly at first, and critically check mowing disc modifications |
| Dreame A3 AWD | Fewer long-term reports available that are reliable for blade formats | Do not mount any third-party blade without exact product assignment |
For the A3 AWD, extra caution applies: fewer experience reports do not mean that every similar blade fits. If you plan a modification intentionally, check the product specification, clearance, and design. For users who want more cutting points, a 7-blade cutting disc for the A3 AWD may be interesting—but only if the specified model matches your robot exactly and installation is possible without grinding contact.
Practical rule of thumb: It’s not the brand name that matters, but the hole pattern, dimensions, mount, clearance, and the exact model match. A “nearly fitting” blade is not a safe blade.
Original, compatible, or cheap? The risk often lies in the screw and mount
New inexpensive third-party blades can initially cut just fine. Many users confirm this with other mowing robots as well. However, that doesn’t mean that every complete set offers the same quality when it comes to screws and mounts. That’s exactly where the critical differences are: poor threads, rust, soft material, loose screws—or, in the worst case, a broken-off remainder in the disc.
From our workshop perspective, the approach is clear: With a compatible blade, we first check the fastening and only then the price. A blade that cuts very well but is supplied with an unreliable screw is not a good replacement. When in doubt, use a proven fastening system or choose a set that combines blade and mount in a clearly understandable way.
When compatible blades can make sense
- If the dimensions, hole pattern, and mounting are clearly compatible with your own model.
- If the blade swings freely after installation and doesn’t rub against the guard.
- If the screws and mounts are cleanly made and engage without force.
- If you check the tight fit again after the first mowing operation.
When it’s better to stick with the proven system
- If a screw becomes difficult to turn or the thread no longer grips properly.
- If the blade only fits with washers, bending, or additional reworking.
- If the disc already shows cracks, play, or damaged mounting points.
- If buzzing, grinding, or imbalance occurs after the replacement.
For compatible A3-AWD variants, a 9-blade solution for precise fine cutting can be an option if you intentionally want to switch the disc as a system. However, it is not a patch for a warped drive, a broken mounting point, or unclear compatibility.
When is the entire cutting disc due—rather than individual blades?
Individual blades are wear parts. The cutting disc itself, on the other hand, should only be replaced if it is damaged, worn out, or can no longer be mounted reliably. Still, its condition is often overlooked because, during replacement, you mainly focus on the small blades.
These types of damage indicate a new disc is needed
- a visible crack in the plastic or at a blade mounting point,
- a missing or broken holder that cannot be replaced individually in a proper, professional way,
- worn-out threads or a stripped screw mounting,
- noticeable play at the disc mounting,
- imbalance, buzzing, or vibration despite correctly installed new blades,
- contact between the blade and the blade guard, even though the correct parts are installed.
Especially when retrofitting mowing discs with more blades applies: More blades are not automatically better. In user reports, alternative 6-blade discs are said to involve, among other things, play at the axle mount, resonances, and blades that drag or grind. Anyone who retrofits must check runout and the distance to the cutting guard very carefully after installation.
Frequently Asked Questions
How often should I change the Dreame blades?
Check the blades every two to four weeks and replace them immediately if the cut pattern is frayed, there are nicks, the blades are difficult to move, or if they are lost. A monthly replacement is a practical routine with frequent use, but it does not replace visual inspection.
Do I also need to replace screws or holders when changing the blades?
Yes—if the mounting parts are damaged, rusty, loose, or unclear, you should replace the screw and the holder right away. Especially user reports about loosened blades show that not only the blade itself is safety-relevant.
What should I do if a blade is missing from the lawn?
Stop the robotic mower immediately and systematically search the lawn, the driving path, and the cleaning area. Do not install a new blade and do not let the robot continue running until the cause has been clarified on the mowing disc, the holder, and the threads.
Why does my Dreame hum after changing the blade?
Humming is usually caused by imbalance, a mowing disc that is not seated correctly, a blade that is binding, or grinding contact with the cutting guard. Switch off the device, check each blade individually, and inspect the mowing disc for cracks or play.
Should I remove leaves and small branches before mowing?
Yes, leaves, branches, pine cones, stones, and fallen fruit should be cleared from the lawn before mowing. They dull the blades faster, can block the cutting mechanism, and increase the risk of damage to the blade, the holder, and the cutting disc.
Conclusion: Clean Dreame blade maintenance starts before the screwdriver
A good blade replacement involves more than three new blades. Check the cutting pattern, free movement, screws, the holder, and the cutting disc together. This is especially relevant for the A1 and A1 Pro, because users repeatedly report lost blades or missing mounting parts. With the A2, the large supply of replacement blades helps, while for the A3 AWD the compatibility of alternative parts should be checked particularly carefully.
The best routine is simple: clear the lawn before mowing, clean the underside regularly, replace the blades as a set at the first signs of wear, and don’t continue driving if you notice vibrations. This keeps the cut clean—and prevents the mowing disc from turning a small, overlooked mounting problem into an expensive replacement part.
