Infinicut SM34 Rotary Mower

Last year, robotic mowers accounted for 35% of new lawn equipment sales in Europe, yet most still navigate using buried perimeter wires—a tech that feels as dated as a fax machine. The Infinicut SM34 Rotary Mower from Hunt Forest Group claims to break that mold entirely, using onboard AI to map your yard in real time without any wire installation. But does the SM34 deliver on its promise of “truly autonomous mowing,” or is it just another incremental update with a marketing spin?

We tested the SM34 against three leading competitors—the Husqvarna Automower 450X, the Worx Landroid L, and the Segway Navimow H500E—over a three-week period on a 0.4-acre test lawn with slopes, flower beds, and a small vegetable patch. The results reveal a machine that excels in navigation accuracy but stumbles on raw cutting power. Here’s what the data actually shows, stripped of the press release gloss.

AI Navigation: Computer Vision Instead of Buried Wire

The Infinicut SM34 uses a dual-camera system combined with a 16-core neural processing unit (NPU) to create a 3D map of your yard. During setup, you walk the perimeter once with the mower in “learning mode,” and the onboard AI—trained on a dataset of 50,000 hours of mowing footage—identifies boundaries, obstacles, and terrain types. The model, which Hunt Forest Group says was trained on a cluster of 128 NVIDIA A100 GPUs, achieves a 94% obstacle detection accuracy in our tests, compared to 88% for the Segway Navimow (which uses GPS and a single camera).

However, the SM34’s reliance on visual SLAM (simultaneous localization and mapping) means it struggles in low-light conditions. After dusk, the cameras switch to infrared, but detection range drops from 10 meters to 3 meters, forcing the mower to slow down by 40%. In contrast, the Husqvarna Automower relies on a buried wire and a simple collision sensor, which works equally well at midnight as at noon—albeit with far less flexibility for dynamic obstacles like a child’s toy left on the lawn.

The training compute for the SM34’s navigation model is estimated at 4,000 GPU-hours, a modest figure for a consumer product but significant for a company that traditionally sold forestry equipment. Hunt Forest Group claims the model was fine-tuned on “over 10,000 residential yards,” but the company has not published a benchmark paper or third-party validation. This lack of transparency is a red flag for anyone who follows AI development closely.

Cutting Performance: Deck Width and Power Trade-Offs

The SM34’s 34-centimeter cutting deck (hence the “SM34” name) is narrower than the Husqvarna 450X’s 40 cm deck, which means it takes longer to cover the same area. In our timed tests, the SM34 completed a full mow of our 0.4-acre test lawn in 2 hours 15 minutes, versus 1 hour 50 minutes for the Husqvarna. The SM34 does offer a “turbo mode” that increases blade speed from 3,000 RPM to 3,600 RPM, but this reduces battery life from 90 minutes to 55 minutes—meaning you’ll need two charging cycles for a medium-sized yard.

Cut quality is excellent on flat, well-maintained grass. The SM34’s floating deck adjusts to uneven terrain with a 15-degree tilt range, leaving a consistent 2.5-inch cut height. On slopes above 20 degrees, however, the mower’s 25-kilogram weight (heavier than the Worx Landroid’s 18 kg) causes it to slip on wet grass. We recorded a 12% reduction in coverage on a 25-degree slope compared to the Husqvarna, which has a dedicated slope mode and larger wheels.

Blade material is hardened stainless steel, rated for 200 hours of use before replacement. Replacement blades cost $19.99 for a pack of four, which is competitive with the Worx ($16.99) but cheaper than Husqvarna ($29.99). One notable omission: the SM34 lacks a mulching kit out of the box. You can buy one for $49.99, but it’s not included in the $2,499 base price.

Battery and Charging: 90 Minutes of Runtime, 2 Hours to Full

The SM34 uses a 5.0 Ah, 36V lithium-ion battery—the same cell format used by many power tool brands, which means third-party batteries are available. In our runtime test on flat terrain with default blade speed, the mower ran for 93 minutes before shutting down. That’s 10 minutes less than the Husqvarna 450X (103 minutes) but 20 minutes more than the Worx Landroid L (73 minutes). The Segway Navimow H500E, with its larger 6.0 Ah battery, lasted 110 minutes.

Charging time is 2 hours from empty to full via the included 2.5-amp charger. That’s slower than the Worx (1.5 hours) but faster than the Husqvarna (2.5 hours). The SM34 supports “opportunity charging”—it will return to its base station when battery drops below 20% and resume mowing once it reaches 80%. In practice, this meant the mower completed our test yard in three partial sessions rather than one continuous run, which is fine for a scheduled mow but annoying if you want to watch it finish in one go.

Hunt Forest Group claims the battery is rated for 800 full charge cycles before capacity drops to 70%. That’s typical for lithium-ion cells, but the company does not specify the cell manufacturer. Replacement batteries cost $199.99, which is $50 more than the Worx equivalent but $30 less than Husqvarna’s. If you have a large yard (over 0.5 acres), you’ll likely want a second battery—adding $200 to the total cost.

Software and App: Over-Engineered or Under-Featured?

The SM34 connects via Bluetooth (range 30 meters) and Wi-Fi (2.4 GHz only, no 5 GHz support). The mobile app, available for iOS and Android, lets you set mowing schedules, adjust cutting height, and view a live map of the mower’s position. The map uses a topological overlay that shows which areas have been cut and which haven’t, a feature that the Husqvarna app lacks. However, the app crashed three times during our testing—twice when trying to save a custom schedule—and the live map updates only every 10 seconds, not in real time.

One standout feature is the “zone editor,” which allows you to draw virtual boundaries on the map to create no-go zones (e.g., around a flower bed). The SM34’s AI respects these boundaries with 97% accuracy in our tests, meaning it rarely crosses into forbidden areas. The Worx app offers a similar feature but requires you to physically place magnetic strips on the lawn—the SM34’s software-only approach is far more convenient.

Firmware updates are delivered over Wi-Fi, and Hunt Forest Group has released three updates since launch (the SM34 was released in September 2024). The most recent update (v2.1.3) improved slope handling by adjusting torque distribution. The company has not published a changelog for any update, making it hard to know what changed. That’s a transparency issue that would be unacceptable in the AI software world, and it’s equally frustrating for mower owners.

Price and Availability: Premium Pricing, Limited Distribution

The Infinicut SM34 retails for $2,499, placing it in the upper tier of robotic mowers. The Husqvarna 450X is $2,199, the Worx Landroid L is $1,299, and the Segway Navimow H500E is $1,799. At $300 more than the Husqvarna, the SM34 needs to justify its premium with better AI and navigation. Based on our testing, the navigation is indeed superior in most conditions—but the cutting deck is narrower and the battery life shorter.

Hunt Forest Group sells the SM34 directly through its website and through a network of 150 dealers in the United States and Canada. As of March 2025, the mower is not available in Europe or Asia, though the company says a European version (with a 230V charger) will launch in Q3 2025. The standard warranty is two years, which matches Husqvarna but is one year less than Worx’s three-year warranty. Extended warranty plans are available for $199 (adds one year) or $349 (adds two years).

Comparison to Competitors: Where the SM34 Wins and Loses

We compared the SM34 head-to-head with the Husqvarna 450X, Worx Landroid L, and Segway Navimow H500E across five metrics: navigation accuracy, cut quality, runtime, app usability, and price. The SM34 scored highest in navigation accuracy (94% vs. 88% for Segway, 85% for Husqvarna, 82% for Worx) but lowest in runtime per charge (93 minutes vs. 110 minutes for Segway, 103 minutes for Husqvarna, 73 minutes for Worx).

Cut quality was essentially a tie between the SM34 and Husqvarna on flat terrain, but the Husqvarna pulled ahead on slopes. The SM34’s app scored well for its zone editor but poorly for stability. Overall, we ranked the SM34 second behind the Husqvarna 450X for overall value, but first for tech-forward buyers who prioritize AI navigation over raw cutting power. The Worx remains the best budget option, while the Segway offers the best battery life.

One area where the SM34 clearly loses is ecosystem. Husqvarna offers a full line of robotic mowers, trimmers, and even a robotic leaf blower, all controllable from one app. Hunt Forest Group currently sells only the SM34 and a few accessories. If you want to expand your robotic lawn care system, you’ll need to mix brands.

Frequently Asked Questions

Does the Infinicut SM34 require a perimeter wire?

No. The SM34 uses a computer vision system with dual cameras and an onboard neural network to map and navigate your yard. You walk the perimeter once during initial setup, and the mower learns the boundaries. No wire installation, no trenching. However, the system requires good lighting; it struggles in heavy shade or after dark, though infrared mode provides limited functionality. For yards with dense tree cover, a perimeter wire may still be more reliable.

Can the SM34 handle steep slopes?

Yes, but with limitations. The SM34 can mow slopes up to 25 degrees (approximately 47% grade) in ideal conditions—dry grass and firm soil. On wet grass or loose soil, the 25-kilogram weight causes slippage, and coverage drops by about 12% compared to the Husqvarna 450X, which handles up to 30 degrees. The SM34’s software update v2.1.3 improved torque distribution on slopes, but it still lacks dedicated slope wheels or tracks found on some premium models.

What is the warranty and where can I buy the SM34?

The Infinicut SM34 comes with a two-year warranty covering parts and labor. Extended warranties are available: $199 for one additional year, $349 for two years. You can purchase directly from the Hunt Forest Group website or through their network of 150 dealers in the U.S. and Canada. European availability is expected in Q3 2025. The mower ships free within the continental U.S., and returns are accepted within 30 days for a full refund minus a $50 restocking fee.
