I think it gets better the lower you put the blades as well. I let my grass grow for over a month to test the limits of the mower and am at 4”(max height) in most areas. I ran a couple areas yesterday at 3.5” and it seemed pretty good. If you look at the blade location when they’re all the way raised there’s only a couple millimeters between the blade and the top of the deck so I think the suction is basically 0 when that high.

I’ve heard the magic max set height sweet spot is 3.5 for the pro and 3 for the M1. At least for my grass type of tall fescue blue grass mix it works well there (or lower). I’ve been mowing at 3 for both modules and it does well there. I may try 3.5 on the pro, as I’d like to go higher.

I’ve now used them on several areas with leaves, and they definitely “mulch”, however the mulching is better when going slower or when the leaves are smaller. And of course, if you run it twice, it mulches quite well. But if you thought these would mulch as well as a gas powered blade, they may be disappointing.

I set my speed slower and lowered the blades to 3.7”, very noticeable difference. I added more pictures to the album above. At 4” there’s barely any space to develop air flow I bet it’s just “cavitating”.

Yeah I have always mowed at the slowest speed. It’s quieter, has more time to react, and leaves a better cut quality while missing less. The pro misses even less thanks to the lift (if you lower the blades down at or below 3.5). Good to know you saw a noticeable difference with 3.7.

What is the status of the upcoming yarbo pro? It is clearly an upcoming product and I as a potential customer I would be extremely upset to spend upwards of $9k only to have a new hardware version come out. It’s clearly more than a concept or prototype. Please give us more details.
Investigation Into Potential Release of Yarbo “Pro Core” Version
There has been speculation and documented photos of a “pro core” version of the Yarbo autonomous yard robot being released. One that features “LiDAR”, “higher battery capacity”, “a revised drive system that is much faster with much less heat whine”, etc. This document provides a detailed analysis of whether a “Pro Core” version release is imminent, based on available information across the internet, trade show sightings, community reports, and Yarbo’s own statements.
- Background: Yarbo’s Current Models and User Concerns
Yarbo is a modular yard robot system, consisting of a Core base unit and various attachments (lawn mower, snow blower, leaf blower, etc.) for year-round yard care. The current generation (2024 model) has faced some limitations in real-world use. Users have reported issues like the mowing module’s small razor-disc blades struggling with thick grass and leaving an uneven cut, as well as hardware problems such as battery overheating in hot weather and a high-pitched whine from the drive motors. These issues have led early adopters to request hardware improvements, including more powerful motors, better cooling, and quieter operation (e.g. via helical gears to reduce gear whine). In mid-2025, Yarbo began hinting at new hardware to address tougher mowing conditions – notably an upcoming “Mower Pro” attachment featuring real mulching blades and doubled motor power. This set the stage for speculation that a full “Yarbo Pro” system (both core and attachments) was on the horizon.
- Emergence of the “Pro Core” Rumors
By mid-2025, rumors of a “Pro” version of Yarbo’s core and mower started circulating in the Yarbo community. Forum posts from June 2025 show users discussing a “Pro model” with substantial upgrades. According to one forum member, the Pro mower module was expected to have “real blades” (not just small cutting razors) and double the motor wattage (300 W vs 150 W) for the mower deck. Indeed, Yarbo later confirmed that the new Lawn Mower Pro attachment uses dual 300 W brushless cutting motors (up from ~150 W), enabling higher blade speed and torque. This allows it to cut thick, 2-inch weeds in one pass and mow dense or wet grass without stalling. The upgraded mower deck also offers an optional set of two straight mulching blades (like a traditional mower) for tougher grass and better cut quality. In short, the “Pro” mower addresses many shortcomings of the original M1 module, promising a cleaner cut and up to 40% faster mowing due to the more powerful motors.
Community speculation quickly extended beyond just the mower attachment – many believed a new “Pro Core” base unit was in development to complement the mower. Key features rumored for the Pro Core include: LiDAR-based sensing, a higher-capacity battery, and a revised drive system that runs faster and cooler with less noise. These expectations stem from the current model’s pain points (navigation challenges, battery heat limits, motor whine) and the need to compete with other high-end robotic mowers. For example, users noted the Yarbo core sometimes loses GPS signal under trees and lacks sophisticated obstacle avoidance (leading to “seeing ghosts” or getting stuck). The mention of LiDAR – a 360° laser sensor – in a future core suggests Yarbo might add advanced autonomous navigation and obstacle detection, similar to competitors that introduced LiDAR-equipped robots in 2025. Likewise, a larger battery or improved battery cooling would help the Pro Core mow larger areas continuously without pausing in midday heat. Many have observed the current 36 V, 38.4 Ah battery will refuse to charge when its temperature exceeds ~50 °C, causing long delays between mowing cycles on hot days. A “higher capacity” battery could mean a physically larger pack for longer runtime, or simply the ability to operate more efficiently so that effective coverage per charge increases. Lastly, a redesigned drive system (motors and gears) could increase transit speed and eliminate the high-pitch gear whine that some owners complained could be heard 20+ feet away. In short, by mid-2025 the community strongly anticipated a Pro Core, seeing it as the platform needed to fully realize the improvements introduced by the Pro mower attachment.
- Evidence from Trade Shows: “Yarbo Pro” Sightings
Concrete evidence of the Pro Core surfaced in late 2025. Yarbo displayed new prototypes at major industry events – notably IFA Berlin (September 2025) and the Equip Exposition (October 2025). Attendees and online viewers spotted a Yarbo unit labeled “Yarbo Pro” at these shows, providing visual confirmation that an upgraded model exists in development. In one forum thread, a user shared screenshots from an IFA 2025 YouTube livestream, noting “this new Yarbo appears to be called the ‘Yarbo Pro’ based on the verbiage on the sides”. The attached images clearly showed a Yarbo unit with “YARBO PRO” branding on its side. More importantly, observers pointed out that “the sensor on the top of the core looks like a LiDAR” – i.e. a small dome or cylindrical sensor perched atop the unit, which was absent on the standard Yarbo. This strongly suggests the Pro Core will include a spinning LiDAR (or 360° camera) for enhanced environmental sensing.
At the Equip Expo 2025 in Louisville, Yarbo had a prominent booth where they demonstrated their robots and brand-new prototypes in live demos. Several attendees reported seeing the Yarbo Pro in action. The widely shared photo from the expo shows the Yarbo Pro prototype with a front-mounted trimmer module. The unit’s side label confirms it is a Pro model, and the top sensor (glossy black cylinder) is consistent with a rotating LiDAR scanner. According to attendee reports, the Pro unit also had different attachments on display – including the Autonomous Trimmer (an edging/weed-whacking module) and the Mower Pro deck with real blades – indicating Yarbo’s next-generation hardware ecosystem. The presence of these prototypes in public expos – even before the original Yarbo has been fully refined via software updates – shows that Yarbo is actively working on new hardware. Visual confirmation at Equip Expo strongly supports that a “Pro Core” release is in the pipeline, even if not officially launched yet.
- Official Statements vs. Insider Clues
Officially, Yarbo’s support and leadership have been cautious about confirming a new core. When pressed by existing customers, representatives initially downplayed the Pro as merely an idea. In a late-September forum discussion titled “Spotted in 2025 Berlin video,” a user asked if there were any specs on the “Pro Core.” Another forum member replied that co‑founder Ken Kohlmann commented on Facebook that “it is just a concept.” This was around September 22, 2025 – likely after many had seen the IFA video. The official line was that the Yarbo Pro was conceptual/prototype only, with no announced release date. Similarly, some customers who contacted Yarbo support were told that no Pro version was currently in development, possibly to avoid stalling sales of the current model. This stance is unsurprising – as a startup, Yarbo wouldn’t want an “Osborne effect” where customers hold off buying the 2024 model in anticipation of a successor. It’s also possible the Pro Core’s exact release timeline wasn’t finalized, so the company kept messaging vague.
However, the gap between official statements and reality has only fueled speculation. The fact that Yarbo chose to publicly showcase the Pro at trade shows (even labeling it clearly) suggests they are serious about bringing it to market relatively soon. Industry trends add context: competitors like Sunseeker Robotics unveiled LiDAR-equipped mowers at the same expo, and others (Segway, Mammotion, Husqvarna, etc.) are pushing next-gen robotic mowers. Yarbo likely must advance its hardware to stay competitive in performance and capabilities. Indeed, Yarbo’s own blog in August 2025 acknowledged the launch of the Yarbo Lawn Mower Pro and an industry-first autonomous trimmer attachment, which garnered media attention from Forbes, SlashGear, etc. This shows the company is already publicly in “upgrade mode,” introducing improved modules. It would be logical that an improved Core (with better sensors and possibly more power) is the next step.
Internal clues can be gleaned from Yarbo’s communications and actions: in fall 2025, Yarbo started taking pre-orders for the new modules and even selling “Pro packages.” On its website, Yarbo advertised the Lawn Mower Pro Module with shipments expected to begin in late November 2025, and indeed the first batch of Mower Pro attachments was reportedly sent out around October. They also opened orders for the Trimmer module, slated for delivery around the same time. Some prospective buyers mentioned bundle deals – for example, a “4-in-1 Pro bundle” including the core and three modules for around $7,000 – indicating Yarbo was marketing a full Pro system option by late 2025. On Reddit, one user even stated “I have ordered a Yarbo pro/trimmer combo”, showing that at least the terminology “Yarbo Pro” was being used in sales/pre-order context. This aligns with forum discussions where new customers were deciding whether to “pull the trigger on a 4-1 bundle of the Pro” system. In short, despite official coyness, Yarbo has been positioning the Pro as an upcoming product for purchasers – it’s not purely an R&D concept behind closed doors.
The Yarbo community remains divided between excitement and frustration. Early adopters who bought the 2023/2024 models feel anxious that “last year’s flagship almost immediately becomes outdated.” Many voiced that Yarbo should offer upgrade or trade-in programs so they aren’t “left behind” after investing thousands of dollars. On the other hand, tech enthusiasts see the rapid development as a good sign that Yarbo is pushing the envelope. Yarbo’s CEO Allen Huang, in an AMA, assured that they would “take full responsibility for marketing promises” and continue supporting current hardware with software updates – implying that core functionality (like promised features) would be delivered even if new hardware comes out. Still, the introduction of LiDAR or other hardware improvements may inherently give the Pro model capabilities that the standard core can’t fully match.
- Analysis of “Pro Core” Features and Imminence
Considering all available information across the internet and community channels, here is a summary of what we know about the Yarbo “Pro Core” and the likelihood of its release:
• LiDAR Sensor – All evidence points to the Pro Core integrating a LiDAR (or similar 360° sensor). The prototype seen at expos had a distinct top-mounted sensor, and both Yarbo insiders and observers identified it as likely LiDAR. This would be a significant upgrade to Yarbo’s navigation, enabling real-time 3D scanning of the environment for obstacle avoidance and mapping without relying solely on RTK GPS and cameras.
• Higher Battery Capacity – It is speculated that the Pro Core might come with an improved battery. The current battery (≈1.4 kWh lithium-ion) gives Yarbo a single-charge mowing capacity of ~0.4 acres and was designed to cover up to 6 acres with periodic recharging. While Yarbo’s official FAQ states the Pro uses the “same battery capacity” as the regular version, this might refer to using the same battery pack for interchangeability. It’s possible that the Pro Core will support a higher-capacity pack or better cooling, since battery overheating has been a major limiting factor (users in warm climates found the Yarbo had to pause charging for 8–10 hours until it cooled down). A “higher capacity” battery could mean a physically larger pack for longer runtime, or simply the ability to operate more efficiently so that effective coverage per charge increases.
• Revised Drive System (Faster & Quieter) – A revamped drive system is very likely part of the Pro Core, although official specs haven’t been released. Current Yarbo cores use dual rubber tracked drive with electric motors and gears that produce a characteristic whine. Users have called for a “Turbo mode” to make the robot traverse faster when not cutting, as well as engineering changes (like helical gears or different motors) to reduce noise. Given Yarbo’s awareness of these requests, the Pro Core will presumably feature upgraded drive motors with higher torque/speed and possibly refined gearing or motor controllers to cut down on the high-pitched noise and heat. At minimum, the Pro mower module itself increases mowing speed (covering the same area ~40% faster), and it wouldn’t be surprising if the core can also move quicker between mowing zones or drive with more agility on slopes.
• Imminent Release – All signs indicate that a Yarbo Pro Core release is on the horizon, likely within the next product cycle. “Imminent” in this context probably means within the next year (late 2025 or 2026 mowing season). Yarbo has already launched the Pro-level attachments (Mower Pro, Trimmer) which early buyers are now receiving. These modules can technically attach to the existing core, but the full benefit (especially of the mower) would be realized with the enhanced core. Prototypes have been demonstrated publicly, which usually happens when a product is close to production. Competitors are moving fast, and Yarbo has investor funding to grow. For all these reasons, the Pro Core’s debut appears to be on the cusp of happening once Yarbo finalizes specs and is ready for a formal announcement.
- Conclusion
It appears that a “Yarbo Pro” version – including a Pro Core base – is indeed in the works and nearing release. Despite official denials early on, multiple independent sources (trade show sightings, forum insiders, and Yarbo’s own product launches) all converge on the same story: Yarbo is preparing a more advanced model with LiDAR for navigation, more robust mowing and driving hardware, and solutions to the current model’s shortcomings. The company’s support team may call it a “concept” for now, but the evidence (even photographic proof from Equip Expo) speaks louder. All signs point to an imminent debut of the Yarbo Pro Core, likely syncing with the full rollout of the Pro mower and trimmer attachments.

If I’m not mistaken, this is about a new ‘Mini Yarbo’ (smaller robot) and not a new version of the Yarbo we all have today.
Guess we’ll soon see. I’ll be there at CES and will post plenty of pics and specs of the new device.

That would be cool if the blade could pivot left and right.
I hope they make a dedicated Plow module with pivoting for ‘Big Yarbo’. That would be better (in my opinion) than the current plow retrofit.

I’d love to have a dedicated plow that would articulate. The issue I see is what to do with that module. I’d rather not have a plow module sitting next to the Yarbo on dock where I need to manually swap them back and forth depending on the amount of snow we get. Personally, I think where I am, a dedicated plow may be used a little more often as we haven’t been getting larger storms. Fingers crossed that I just jinxed us and we get some nice snow storms this season!
We’ll end up needing that module swapping robot sooner rather than later.
