Introduction
Owning a robotic lawn mower is one of the smartest investments a homeowner can make in 2026. These machines quietly handle one of the most tedious weekend chores, freeing you up to enjoy your yard instead of laboring over it. But like any piece of outdoor equipment, robotic mowers need a little maintenance to keep running at peak performance. One of the most overlooked issues? Grass buildup on the wheels.
When grass clippings, mud, and debris accumulate on your mower’s wheels, traction suffers. The mower starts slipping on slopes, struggling on uneven terrain, and performing below its potential. That’s exactly the problem the WORX 2WD Robotic Lawn Mower Wheel Brushes (WA0940) aims to solve. Priced at $39, this accessory promises to keep your WORX 2WD robotic mower running smoothly with minimal effort on your part.
In this in-depth review, we’ll break down everything you need to know about this product — from installation and performance to pros, cons, and whether it’s truly worth your hard-earned money. If you own a compatible WORX robotic mower, keep reading before you decide to add this to your cart.
Product Overview
The WORX WA0940 is a set of wheel brushes specifically designed for WORX’s 2WD (two-wheel drive) robotic lawn mower lineup. Rather than being a standalone cleaning tool, these brushes attach directly to your mower and work passively — meaning they clean the wheels as the mower drives, eliminating the need for manual scrubbing after each mowing session.

The concept is straightforward: as your robotic mower navigates your lawn, these brushes continuously sweep away grass clippings and debris that would otherwise cake onto the wheels. This helps maintain consistent traction, reduces slipping on slopes, and keeps the mower performing as the manufacturer intended. For anyone who has pulled their robotic mower out of the garage only to find the wheels caked in dried grass, this is a welcome solution.
Pros: Why the WORX WA0940 Wheel Brushes Stand Out
Eliminates Manual Wheel Cleaning
The single biggest advantage of this product is the time and effort it saves. Without wheel brushes, you’ll eventually need to manually clean grass buildup off your mower’s wheels — a messy, annoying task that most owners dread. The WA0940 handles this automatically as the mower operates, so you can spend your time on more enjoyable activities rather than crouching over your mower with a brush and a bucket of water.
Maintains Traction on Slopes and Uneven Terrain
Grass buildup on wheels doesn’t just look bad — it directly impacts performance. When wheels lose their grip, the mower struggles on hills, slips on wet grass, and may even get stuck in certain areas. By keeping wheels clean, these brushes ensure your mower maintains the traction it was designed to have. If your lawn has any slopes or challenging terrain, this benefit alone can justify the $39 price tag.
One-Time, Effortless Installation
WORX designed the WA0940 for quick and easy installation. You attach the brushes once, and they do their job every time the mower goes out. There’s no complex setup, no need for specialized tools, and no ongoing adjustment required. For busy homeowners — especially those who aren’t particularly handy — this simplicity is a major plus.
Extends the Life of Your Mower’s Wheels
Constant grass and debris buildup can degrade wheel surfaces over time. The abrasive action of dried grass, combined with moisture, can cause premature wear. By keeping wheels clean during every mowing session, these brushes help protect your investment and potentially extend the usable life of your mower’s wheels and drive system.
Seamless, Set-and-Forget Design
Unlike some accessories that require regular attention or adjustment, the WA0940 operates passively. Once installed, you don’t need to think about it. The brushes clean as the mower drives, and they’re designed to last through regular mowing sessions without requiring replacement or maintenance. This is exactly the kind of accessory a robotic mower owner wants — one that works without adding to the maintenance workload.
Purpose-Built for WORX 2WD Models
Unlike generic aftermarket solutions that may not fit properly, the WA0940 is an official WORX accessory engineered specifically for their 2WD mower lineup. This means you get a precise fit, reliable performance, and the assurance that the accessory won’t interfere with your mower’s operation or void any existing warranty considerations.
Affordable Price Point
At $39, the WA0940 sits at a reasonable price point for an official OEM accessory. Considering that a set of replacement wheels for a robotic mower can cost significantly more, and that the time saved on manual cleaning has real value, this is a cost-effective investment for most WORX 2WD mower owners.
Cons: What Could Be Better
Limited Compatibility
The most notable drawback is that the WA0940 only works with specific WORX 2WD models: the WR310, WR310.1, WR320, WR320.1, and WR340. If you own a different WORX robotic mower — or a mower from another brand entirely — these brushes won’t work for you. This narrow compatibility means a significant portion of robotic mower owners are simply out of luck.
Very Few Customer Reviews
As of July 2026, this product has only one customer review on Amazon. While that single review is a perfect 5 out of 5 stars, one data point isn’t enough to draw broad conclusions about long-term durability, performance across different lawn conditions, or potential issues that might emerge after months of use. Buyers who rely heavily on peer reviews may feel uneasy making a purchase based on so little feedback.
Brush Replacement Costs Over Time
While the brushes are designed to be durable, they are ultimately a consumable component. Over time, bristles will wear down and lose effectiveness. The long-term cost of replacement brushes isn’t clearly outlined, and if WORX charges a premium for replacements, the total cost of ownership could creep up over the years. This is worth considering if you’re evaluating the product’s long-term value.
Potential Performance Variability by Lawn Type
The effectiveness of wheel brushes can vary depending on your lawn conditions. If you mow very wet grass, have a lot of mud, or deal with extremely long clippings, the brushes may not keep up as effectively as they would on a well-maintained, dry lawn. The product description doesn’t provide detailed guidance on lawn conditions where the brushes perform best, which could leave some buyers guessing.
No Adjustable Tension or Cleaning Intensity
The WA0940 is a fixed-design accessory. There’s no way to adjust how aggressively the brushes clean or how much pressure they apply to the wheels. While this simplicity is a pro for most users, it means you can’t fine-tune the product to match your specific lawn conditions. If the default design doesn’t work perfectly for your terrain, you’re out of luck.
Customer Reviews Analysis
With only one customer review currently available, the review landscape for the WORX WA0940 is extremely limited. The sole reviewer awarded the product a perfect 5 out of 5 stars, which is encouraging but hardly conclusive.
Here’s what we can take away from the available data:
- Positive Sentiment: The existing reviewer clearly had a satisfying experience, suggesting the product delivers on its core promises of easy installation and effective wheel cleaning.
- Limited Scope: A single review cannot account for the wide range of lawn conditions, climates, and usage patterns that real-world customers experience. What works perfectly on a flat, dry suburban lawn in one region might perform differently on a hilly, humid property elsewhere.
- Early-Stage Product: The low review count may indicate that this is a relatively new product or a niche accessory that hasn’t yet reached critical mass in terms of adoption. As more customers purchase and use the WA0940 over the coming months, we can expect a more complete picture to emerge.
Our recommendation: Don’t let the single review discourage you, but also don’t base your entire purchasing decision on it. Consider the product’s design logic, official WORX backing, and the clear problem it solves. The lack of negative reviews is itself a mild positive signal — it suggests no one has had a notably bad experience.
Frequently Asked Questions
Will the WA0940 wheel brushes fit my WORX mower?
The WA0940 is specifically designed for the following WORX 2WD robotic mower models: WR310, WR310.1, WR320, WR320.1, and WR340. If your mower is not on this list, these brushes will not be compatible. Always double-check your exact model number before purchasing, as even slight model variations can affect fit.
How long do the wheel brushes typically last?
WORX does not publish a specific lifespan for the WA0940 brushes. Durability will depend on factors like mowing frequency, lawn conditions, and grass type. Under normal usage — mowing a standard residential lawn a few times per week — you can reasonably expect the brushes to last through at least one full mowing season. Inspect them periodically for signs of excessive wear, and replace them when bristles become noticeably shortened or ineffective.
Does the brush installation require any tools?
One of the key selling points of the WA0940 is its tool-free, easy installation. The brushes are designed to snap or clip onto the mower’s wheels quickly and securely. Most users should be able to complete the installation in just a few minutes without any specialized equipment.
Do these brushes affect the mower’s battery life or performance?
The WA0940 brushes add a negligible amount of friction to the mower’s wheels. In real-world use, any impact on battery life should be minimal and practically unnoticeable. The benefit of maintained traction actually works in your mower’s favor — a mower with clean wheels doesn’t waste energy slipping and struggling, which can partially offset any tiny increase in rolling resistance from the brushes.
Can I use these brushes on wet grass?
Yes, the brushes are designed to work in various conditions, including wet grass. However, extremely muddy conditions may overwhelm the brushes, as thick mud can adhere more stubbornly than dry grass clippings. For best results, try to avoid mowing in excessively wet or muddy conditions when possible — which is good practice for your mower’s overall health regardless of whether you use wheel brushes.
Who Should Buy This Product
The WORX WA0940 wheel brushes are a smart purchase for a specific group of homeowners. Here’s who will benefit most:
- WORX 2WD Robotic Mower Owners: If you own a WR310, WR310.1, WR320, WR320.1, or WR340, this is a no-brainer accessory. It solves a real problem specific to your mower at a reasonable price.
- Homeowners with Sloped or Hilly Lawns: If your property has any significant inclines, maintaining wheel traction is critical. These brushes help ensure your mower can climb slopes reliably without slipping.
- Busy Homeowners Who Value Low Maintenance: The entire appeal of a robotic mower is hands-off lawn care. If you want to minimize every aspect of maintenance — including wheel cleaning — these brushes align perfectly with that philosophy.
- People in High-Growth Grass Areas: If you live in a region where grass grows aggressively and produces heavy clippings, wheel buildup will be a more frequent problem. The WA0940 addresses this proactively.
- Anyone Protecting Their Mower Investment: Robotic mowers aren’t cheap. Accessories that extend the life of your mower and keep it performing well are a smart way to protect that investment over the long term.
Who should skip this product? If you own a robotic mower from a different brand or a WORX model not listed in the compatibility range, this product simply won’t work for you. Additionally, if your lawn is completely flat and you rarely deal with grass buildup on your wheels, you may not notice enough benefit to justify the purchase.
Final Verdict
The WORX 2WD Robotic Lawn Mower Wheel Brushes (WA0940) is a well-designed, purpose-built accessory that solves a genuine problem for WORX 2WD robotic mower owners. At $39, it offers a compelling combination of convenience, performance protection, and long-term value. The one-time installation and self-cleaning design mean you install it once and forget about it — exactly what you want from a robotic mower accessory.
The limited compatibility is the biggest caveat. If your mower isn’t on the supported list, this product isn’t for you. And with only one customer review backing it up, there’s an inherent risk in trusting the product’s long-term reliability. However, the fact that it’s an official WORX accessory — not a cheap third-party knockoff — provides a meaningful level of confidence in its quality and fit.
For the target audience — WORX 2WD mower owners dealing with grass buildup and traction issues — the WA0940 earns a strong recommendation. It’s affordable, effective in concept, easy to install, and addresses a maintenance pain point that every robotic mower owner eventually encounters. As more customer reviews come in over the coming months, we’ll have a clearer picture of its long-term durability, but based on everything available as of July 2026, this is a worthwhile addition to your lawn care toolkit.
Rating: 4.5 out of 5 stars — deducted half a star solely due to limited compatibility and the thin review base. For compatible mower owners, this is a practical, well-priced upgrade that earns its spot in your garage.
