| This robotic lawn mower makes sense in autumn too: Anthbot N8 review |
Verdict: A Specialized Machine That Solves a Real Problem
Let me be upfront about something: I've tested my fair share of robotic lawn mowers over the years, and most of them do essentially the same thing. They cut grass. Some do it well, some do it poorly, but they all follow the same basic formula.
The Anthbot N8 is different. This is a robot mower that doesn't just cut your grass—it collects the clippings, sweeps up leaves, and actually empties itself into designated drop zones around your yard. It's a genuinely novel approach to automated lawn care, and for anyone who's ever spent a crisp October afternoon raking leaves, that 23L collection bag starts looking pretty appealing.
But here's the thing: innovation often comes with compromises. After spending several weeks putting the N8 through its paces, I can tell you that this mower is brilliant at some things and frustrating at others. Whether it's right for your garden depends entirely on what you need from a robot mower.

Design and Build Quality: Big, Bold, and a Little Awkward
The Elephant in the Garden
There's no polite way to say this: the Anthbot N8 is a chunky piece of equipment. At nearly one meter long when the collection basket is attached, this is not a nimble little garden helper that will zip between flower beds and navigate tight corners with grace.
The mower measures 61 cm in length for the main body, but add the rear-mounted collection basket and you're looking at close to a full meter of robotic machinery. For large, open lawns, this isn't a problem. For intricate gardens with narrow passages, tight turns, and lots of obstacles? You're going to have issues.
During my testing, I found the N8 struggled noticeably when maneuvering around obstacles and navigating tight spaces. The sheer length of the machine means its turning radius is compromised, and it frequently left patches of uncut grass in corners and along edges that smaller mowers would have handled without complaint.
The Collection System
The N8's party trick is its rear collection system, and I have to admit—watching it work is genuinely satisfying. The mower uses a cyclone system that doesn't just cut grass but actively vacuums clippings and leaves through a rear opening into the attached basket.
When the basket fills up (or at predetermined intervals), the N8 navigates to one of up to five designated drop-off points you've set in the app. It then performs a rather elegant maneuver: rotating in place and lifting the basket to dump its contents. The first time you see it happen, you'll probably want to show someone.
The 23L capacity means fewer interruptions during large jobs, and the automatic dumping worked flawlessly throughout my testing period.

Here's where I need to raise a flag. The collection basket itself doesn't feel particularly robust. It's constructed from a wire frame with a fabric cover, and while it survived my testing without incident, I'm not confident it would handle years of regular use without showing wear.
The mower seems aware of its vulnerable rear attachment, though—it rarely bumped the basket into obstacles during testing, which suggests the navigation system accounts for the extra length.
One practical issue I discovered: after rain, water pools on top of the collection bag. If you don't have a covered parking spot or garage for your mower, you'll want to empty and dry the bag regularly to prevent mildew.
Setup and Installation: More Manual Than I'd Like
Initial Assembly
Getting the N8 ready for its first mow involves the usual steps for an RTK-based robot mower:
- Position and connect the charging station
- Set up the RTK reference antenna (requires a reasonably clear view of the sky)
- Power on the mower and connect it to your Wi-Fi network
- Assemble at least one of the two basket attachments
The basket assembly is straightforward—you're essentially building a wire frame and stretching a fabric cover over it. The instructions are clear enough, and the whole process took me about 15 minutes per basket.
The Mapping Process: A Test of Patience
Here's where the N8 shows its age compared to newer competitors. Unlike many modern robot mowers that offer AI-powered automatic mapping, the Anthbot N8 requires manual mapping.
You'll need to physically drive the mower around your entire lawn using virtual joysticks in the smartphone app. This is tedious, time-consuming, and—thanks to the N8's size—more difficult than it needs to be. The controls are sensitive, and the mower's momentum means it sometimes travels further than you intended.
For a 1,500 m² lawn, expect to spend a significant amount of time on this process. Budget at least an hour for a medium-sized garden, possibly more.
Setting Up Drop Zones
After mapping, you'll need to designate between one and five dumping areas where the mower will empty its collection bag. These spots need to be:
- Accessible to the mower (remember, it's nearly a meter long)
- Not too close to lawn edges
- Somewhere you don't mind grass clippings accumulating
The mower will rotate in place at potential dump sites to verify they're suitable, which is a nice touch that prevents frustration later.
App and Controls: Functional but Not Polished
The Three Modes
The Anthbot app gives you three primary operating modes:
- Collect Mode: Uses the standard mowing deck and collection bag to cut and collect grass clippings
- Sweep Mode: Also uses the collection bag but is optimized for gathering leaves and debris
- Mulch Mode: Requires swapping to the mulching disc and discharge deflector, returning clippings to the lawn
Switching between modes isn't something you can do remotely—it requires physically changing the mower's configuration. If you want to mulch during the growing season but collect leaves in autumn, you'll need to manually swap components.
Customization Options
For each mode, you can adjust:
- Cutting height (30-70mm in 5mm increments)
- Number of mowing passes (one or two)
- Mowing speed (three settings)
- Lane spacing (two options)
- Mowing direction
- Obstacle detection sensitivity (Low, Medium, High)
App Quirks
The app itself is functional but not without issues. Some menu items weren't fully translated (I noticed German text appearing in places), and the interface feels less polished than what you'd find from established competitors like Husqvarna or Worx.
One feature I appreciated: you can manually trigger an emptying cycle at any time by tapping an icon in the app. This is useful if the bag fills unexpectedly or you need to interrupt a job.
However, I couldn't find any way to adjust the automatic emptying frequency. Based on my observations, the N8 empties approximately every 100 minutes, which seems arbitrary and isn't adjustable—a strange limitation.
Navigation and Obstacle Detection: A Mixed Bag
RTK Navigation Performance
For the most part, the N8's RTK-based navigation worked reliably across my two test areas. The mower covered lawns systematically and returned to its charging station without getting lost.
The Full-Band RTK system, which Anthbot claims can receive signals from all 155 GPS satellites, did seem to provide stable positioning. I didn't experience the frustrating "lost signal" errors that plague some RTK-based mowers.
The Size Problem
The biggest navigation issue isn't technology—it's physics. The N8's near-meter length makes it fundamentally unsuited for complex garden layouts. It's best for large, open lawns with few obstacles and simple shapes.
Edge performance is particularly disappointing. The 20cm cutting deck sits in the middle of a 43cm-wide body, meaning the mower leaves wide strips of uncut grass along borders. Even with edge-mowing routines, the N8 can't get as close to boundaries as smaller competitors.
Obstacle Detection: Inconsistent Results
The N8 uses two front-mounted HDR cameras for obstacle detection. In theory, this system can identify over 1,000 different objects. In practice, results were inconsistent.
What it detected reliably:
- Soccer balls
- Garden hoses
- Objects around 10cm or larger
What it struggled with:
- Tennis balls (failed completely)
- Hedgehog decoys (bumped into them more than half the time)
The mower also occasionally touched obstacles while turning, even at the highest sensitivity setting. This isn't terrible, but it's below average compared to competitors I've tested.
Mowing and Collection Performance: Where the N8 Shines
Grass Cutting Quality
When it comes to actually cutting grass, the N8 performs well. The 4,000 RPM blade disc, combined with U-shaped path planning, produced a clean, even cut. The results were comparable to traditional mowing decks I've tested.
The ability to handle longer grass is a genuine advantage. While most robot mowers need frequent runs to maintain a lawn, the N8's collection system means it can tackle slightly overgrown areas without leaving clumps behind.
Leaf Collection: The Killer Feature
This is why you'd buy the Anthbot N8. During autumn testing, the cyclone collection system proved remarkably effective at gathering fallen leaves. Aside from a few stragglers, the mower collected everything in its path and deposited it at the designated dump zones.
For anyone with mature trees on their property, this feature alone could justify the N8's price tag. No more raking. No more leaf blowers. Just schedule the mower and let it handle the cleanup.

Here's the catch: the N8 cannot operate without either the collection basket or discharge deflector attached. The mower has a large rear opening that must be covered—either with the basket for collection mode or the deflector for mulching.
This means you can't run the N8 in a compact configuration for regular mowing and only attach the collection system when needed. The Mammotion Yuka handles this better with its rotating brush system, which can be used independently of the main mowing function.
Runtime and Energy Consumption: Not Winning Any Efficiency Awards
Battery Performance
The 9.2 Ah / 198 Wh battery delivered approximately two hours of runtime in my testing—slightly better than Anthbot's official estimates. During that time, the mower covered about 200 m² before returning to charge with roughly 15% battery remaining.
Charging takes approximately 80 minutes, during which the system draws about 200 Wh.
Energy Efficiency Concerns
Extrapolating these numbers to a typical usage scenario—500 m² mowed three times weekly—the N8 would consume around 16 kWh. That's on the high side compared to more efficient competitors.
Part of the problem is standby consumption, which exceeded 10W while the mower waited for its next scheduled run. Over time, that adds up.
Noise Levels: Not So Quiet
Anthbot's marketing materials claim noise levels of ≤58dB in mow/mulch mode and ≤68dB in collect/sweep mode. My measurements told a different story.
I recorded approximately 70dB from one meter away—nearly as loud as a conventional lawn mower. This somewhat defeats the purpose of a robotic mower, which is supposed to be quiet enough to run at night or early morning without disturbing neighbors.
There is a quieter mode with reduced blade speed, but this also reduces cutting effectiveness.

Final Verdict: A Specialized Tool for Specific Situations
The Anthbot N8 isn't trying to be everything to everyone. It's a specialized machine designed for a specific purpose: automated lawn maintenance that includes debris collection, not just grass cutting.
In that narrow mission, it succeeds. The collection system works brilliantly, the automatic dumping is reliable, and for autumn leaf cleanup, this mower is genuinely transformative.
But those strengths come with real compromises. The N8 is large, loud, and not particularly agile. Its obstacle detection is average at best. The manual mapping process is tedious. And at $1,699, it's competing with more polished, more versatile alternatives.
My recommendation: If you have a large, open lawn with trees that drop leaves, and you value the collection feature enough to overlook the N8's shortcomings, this mower could be exactly what you need. For everyone else, there are better-rounded options available.
