Compatibility – EUFY
Fits the following robotic mowers:
- ✓ E15
- ✓ E18
With the E15 and the E18, EUFY has arrived in the garden – and many owners face the question for the first time in their first season: which wear part do they actually need to reorder? The answer is the cutting disc: available here as a replacement mowing disc with 6, 7 or 9 blades, ready to ship from stock and pre-assembled.
6, 7 or 9 blades – which cutting disc for your EUFY?
All three versions sit on the same mounting for the EUFY E15 and E18 – so you are not choosing between „fits“ and „does not fit“, but between two designs: the 6-blade version with blade guard, which keeps the blades in position, as well as the 7- and 9-blade versions with an open, grass-blocking-resistant design and more cuts per revolution. More blades mean a finer cut pattern.
The version for everyone who simply wants to replace the worn mowing disc. As the only version, it comes with a blade guard that securely holds the blades in position and supports the guidance during operation – the obvious choice for the first replacement.
Seven cutting points per revolution increase the hit rate on the blade of grass; the result is finer. The open design with low grass-blocking helps cuttings pass through more easily – useful where the lawn grows vigorously or is still damp in the morning.
Nine blades deliver the finest cut pattern in this series: the grass is cut into smaller pieces and then falls back unobtrusively between the blades. For lawn areas that should still look evenly maintained even from a distance of two meters.
New robotic lawnmower, classic wear-and-tear question
A robotic lawnmower is a device that works unobtrusively for months – until the cut pattern suddenly no longer matches. With EUFY E15 and E18, the cause is almost always the same as with any other robotic lawnmower: the blades are dull, or the mowing disc has seen its best days.
The signs are easy to spot. Blade tips look frayed instead of cleanly cut, the cutting edges turn brown after one or two days, individual blades of grass remain standing, and the cutting system runs more unevenly than at the beginning. Unusual noises or recurring grass blockages also fall into this category.
Important to know: The robotic lawnmower is not defective then – it is a wear part that is replaced on a regular schedule. This cutting disc is exactly for that. It not only renews the blades, but the entire component on which the Klingen sit, including the mounting and guide.
Also good to know, because it is often confused: E15 and E18 use the same 20-cm disc, while the smaller EUFY C15 uses a compact 18-cm variant. Between the two series, the discs are not interchangeable – for the C15 we supply separate, precisely fitting mowing discs.
Swap it in a quarter of an hour – and without waiting
Even the first time, the replacement is not a job for a specialist service. Switch the robotic lawnmower off completely, turn it over carefully, remove any grass residue from the underside, unscrew the old disc, fit the new one and tighten it. In practice, that takes about ten to fifteen minutes.
You don’t need special tools for this – a suitable screwdriver is enough. We still recommend wearing gloves: Even blades that have become dull from cutting grass still cut well enough for a finger. Make sure the disc sits cleanly and firmly so that no imbalance occurs.
The blades are already fully assembled. So you don’t have to screw anything in individually and you don’t need to look for parts – the disc comes ready for installation straight out of the packaging and the robotic lawnmower can mow on right away.
And the point that matters most for a still young brand in the garden: availability. These cutting discs are in stock with us and ship out in the short term – you don’t have to wait weeks for an original part while the lawn keeps growing.
Simply select the appropriate version above – 6 blades with blade guard, 7 or 9 blades with a grass-blocking-resistant design, and if you want, right away as a set with 60 replacement blades. Each version fits EUFY E15 and E18 and is delivered with blades ready assembled.
Top reviews
I swapped this mower blade disc on my EUFY E18 and it fit exactly like it should. The blade guard is a nice touch, and the 6 included blades made it easy to replace everything at once—no hunting around for compatible parts. After a week on my 200 m² lawn, the cut looks even and I’m seeing less grass buildup around the cutting area. Installation was straightforward once I followed the alignment carefully.
I bought this cutting disc for my EUFY E18 after trying two other brands, because I wanted something that would fit perfectly without any hassle. It came with blade protection and 6 blades, and the actual replacement was quick, and I can especially see fewer grass clippings around the cutting system. I gave it 4 out of 5 because it requires a bit more precise installation the first time before it sits completely flat. Otherwise it feels stable and provides a nice, even cut.
After trying two other brands, this cutting disc for my EUFY E15 finally fit without any hassle. The included guard snaps on cleanly, and the 6 blades are easy to swap—my cutting deck feels much steadier, with less grass buildup around the blades after a few runs. The only downside is that the disc is a little tight to seat at first, so I had to press firmly to get it aligned.

Frequently asked questions
I’ve only had my EUFY since this season—when is the first cutting disc due at all?
There is no fixed date; the cutting pattern is what matters. As long as the tips of the blades look cleanly separated, everything is fine. Frayed tips, brownish cutting edges, blades left standing, or an uneven run of the cutting system are signs that the blades and mowing discs are worn out. This is not a defect in the robot, but the planned replacement of a wear part.
Does one disc fit both models, E15 and E18?
Yes. EUFY E15 and E18 use the same mowing disc mount; each of the three variants fits both mowing robots. So you don’t need to look for model-specific replacement parts and you can use the same supply for two devices in the household.
Does this cutting disc also fit the smaller EUFY C15?
No. E15 and E18 work with the 20-cm cutting disc, while the C15 uses a compact 18-cm variant. The discs are not interchangeable between the two series, even if they look similar in photos. For the C15, we offer a separate, perfectly fitting disc—so please order by model name.
Do all three versions have a blade guard?
No, and that’s an important difference: Only the 6-blade version is supplied with a blade guard that keeps the blades in position and supports guidance during operation. The 7-blade and 9-blade discs instead use an open design with low grass-blocking characteristics, allowing cuttings to flow away more easily.
6, 7 or 9 blades – how do I decide as a beginner?
If you simply want to replace the worn mowing disc, choose the 6-blade version with blade protection. The 7-blade version makes one more cut per revolution and hits the individual blade of grass more often. As a precision mowing disc, the 9-blade version delivers the finest cutting pattern in the series and is worth it if the robot drives frequently and only removes a small amount of grass length each time. More blades mean finer cutting, not more mowing performance.
What tool do I need for the replacement, and how long does it take?
Special tools are not necessary; a suitable screwdriver is enough. Completely switch off the robot, turn it over carefully, clean the underside of grass clippings, unscrew the old disc, attach the new one, and tighten it securely. In practice, this takes about ten to fifteen minutes. Wear gloves during this process—even dull blades still cut.
Do I have to screw the blades onto the disc myself?
No. The blades are already fully assembled: six blades for the 6-blade disc, seven for the 7-blade disc, and nine for the 9-blade disc. The cutting disc comes ready to install from the packaging—you don’t need to screw anything on individually and you don’t have to sort small parts.
Why a CUT GUARD disc instead of the original part from EUFY?
Because it is a wear part that you should get quickly. This cutting disc is a compatible replacement part from CUT GUARD – made to fit precisely for the E15 and E18 mount, designed for continuous operation, in stock with us and available for short-term delivery. Instead of waiting for weeks for an original part while the lawn keeps growing, your robot mower continues mowing right after the replacement.
