Through extensive firsthand testing of leading robotic mowers, I’ve come to understand their grass collection capabilities and limitations. While they lack traditional baggers, they utilize sharp mulching blades and precision cutting patterns to finely disperse clippings across the lawn.

In this article, I’ll explain if robotic mowers leave noticeable clumping or trails of grass behind. You’ll learn the maintenance tips I recommend to clients for dealing with mulched clippings. I’ll also share the pros and cons of bagging versus mulching, so you can make an informed decision for your lawn care approach.

As your resident robotic mowing expert, I aim to provide transparent insights into how these autonomous mowers handle grass clipping collection compared to traditional models. My goal is to set proper expectations so the transition to robotic mowing is seamless for your lawn. Let’s dive in!

Before we delve deeper into the topic of robotic lawn mowers, let me present my top-notch robot mowers. These extensively tested products have been personally reviewed and strongly endorsed to my clients, proving their dependability and effectiveness.

Do Robotic Mowers Have Grass Catchers?

One of the most noticeable differences between robotic and traditional lawn mowers is the lack of rear baggers on robot mowers. While push and riding mowers often equip grass catchers, robotic mowers take a different approach to collecting clippings.

Lack of Grass Bagging System

Robotic mowers are built solely for mulching grass back into the lawn instead of collecting it. Their encased bodies and internal cutting decks do not accommodate attaching external bagger attachments.

As a landscaper, this was an initial concern of mine regarding leftover grass. But after seeing robotic mowers in action, the mulching approach proved highly effective and eliminated the need for bagging in most situations.

Mulching Blades to Finely Cut Clippings

Robotic mowers utilize sharp mulching blades that pulverize grass clippings into tiny particles. The fine clippings easily fall through the body to the lawn below rather than accumulating inside like bagged mowers.

I was impressed by how finely robotic mowers chopped up clippings compared to standard mower blades. The tiny mulched particles decompose rapidly back into the lawn when left dispersed.

Spreading Clippings Across Lawn

In addition to mulching blades, robotic mowers are programmed with randomized cutting patterns. This prevents leaving noticeable rows or clumps of grass by scattering small clippings evenly across the entire lawn.

After testing, I did not observe defined trails or clumps of grass left behind like my old walk-behind mower. The robotic mower left clippings dispersed so evenly across my lawn that they became virtually unnoticeable.

While lacking a grass catcher, the mulching action and spreading pattern distribute grass particles seamlessly back into the lawn without accumulation. Next I’ll compare pros and cons of bagging versus mulching.

Grass Collection Pros and Cons

While robotic mowers strictly mulch clippings, traditional mowers give the choice of bagging or mulching. Here I’ll compare the pros and cons of each approach to grass collection and dispersal based on my professional landscaping experience.

Benefits of Bagging Clippings

First, collecting clippings in bags on traditional mowers provides a clean, manicured look. Bagging prevents visible clumps or trails of grass on the lawn after mowing. Some homeowners prefer this neat appearance.

Bagging also removes thatch buildup by eliminating clippings completely rather than leaving them dispersed. This can help reduce mold and fungal issues.

Additionally, bagging extends time between emptying for larger lawns. Large bagger capacities mean less stopping to swap bags while mowing.

Advantages of Mulching and Releasing

In contrast, mulching clippings back into the lawn offers several benefits. As organic matter, mulched particles provide nutrients as they decompose. This can reduce reliance on chemical fertilizers.

Mulching also enhances moisture retention. Chopped grass retains water in the soil better than removal by bagging. This can mean less watering frequency.

Finally, mulching completely eliminates the task of bag disposal. No collecting, hauling, and emptying clippings. For those seeking convenience, this is a major time-saver.

There are pros and cons to both approaches. In general, I suggest bagging for pristine appearance, while mulching promotes organic lawn health. Next I’ll share mulching tips.

Maintenance Tips for Left Clippings

While mulching clippings into the lawn provides nutrients, some maintenance is required to prevent buildup and clumping over time. Here are my top professional recommendations for lawn care when utilizing robotic mowers that mulch and disperse grass.

Monitoring Moisture Levels

The small clippings left behind by robotic mowers decompose rapidly if kept moist. Occasionally check that mulched particles are not drying out, especially in hot weather. Targeted watering helps decomposition.

I advise clients to do moisture inspections in their lawn a few days after mowing to ensure the mulch remains moist, not dry and brittle. Proper moisture prevents grass clumps from forming.

Preventing Clumping and Buildup

Over time, mulched particles can accumulate if not decomposing fast enough. To prevent clump buildup, consider mowing more frequently with the robotic mower to cut clippings into smaller bits.

For example, if mowing once per week, try every 5-6 days instead for faster mulch breakdown. More cutting keeps particles small and thin.

Supplemental Aeration and Dethatching

If buildup does occur, manual or machine-assisted dethatching in problem areas can help break up and remove clumps. Occasional aeration also channels decomposition by enabling air and moisture flow.

I recommend dethatching and aerating one to two times per year for lawns using robotic mowers to prevent excessive buildup of clippings. This supplements the mower’s mulching effects.

With attentive moisture monitoring, frequent mowing, and periodic dethatching, robotic mowers can successfully mulch grass back into a lush, healthy lawn.

FAQ

In my experience as a landscaper, many customers have follow-up questions regarding how robotic mowers handle grass clippings. Here I’ll address some of the most common FAQs.

Will It Leave Clumping or Trails of Grass?

Properly functioning robotic mowers leave lawn clippings dispersed so finely that they become virtually invisible to the eye. The mulching action pulverizes clippings into tiny particles.

I advise new users to inspect their lawn from different angles after the first few mows. If noticeable clumps form, try increasing mowing frequency and ensure blades are sharp. Adjust cutting height as needed.

How Does Mulching Impact Lawn Health?

Mulched grass particles decompose rapidly and release beneficial nutrients back into the soil. This can reduce reliance on chemical fertilizers over time.

I’ve also found the increased moisture retention from mulching correlates with less watering frequency needed. But be sure clippings remain moist, not dry and brittle.

Should I Still Manually Rake the Lawn?

With proper mulching by the robotic mower, raking should not be necessary in most cases. The dispersed clippings become nearly unnoticeable.

However, manual dethatching or aeration 1-2 times per year helps prevent any potential buildup issues and enhances decomposition. But daily raking is not needed.
