If you clean ball fields, sidewalks, bleachers, warehouses, or big indoor floors, you know how fast dust and trash pile up. Brooms are slow, blowers scatter debris, and gas vacuums are loud, heavy, and expensive. That is where the Stihl KGA 770 cordless sweeper steps in.

This walk-behind sweeper just hit the US after being in Europe, and it promises to act like a powered push broom that also collects debris. In other words, less sweeping, less bending over, and less dust in your face. In this field test, it gets run on synthetic turf, around a Little League complex, on sidewalks, and under bleachers to see what it really can (and cannot) do.

The Stihl KGA 770 is a battery powered walk-behind sweeper in Stihl’s professional AP battery lineup. It is designed to replace:

• A broom
• A shop vacuum
• Part of what you do with a blower

In the test, it is priced at $1,039.99 and described as a very powerful tool that fits into Stihl’s pro-grade battery ecosystem.

A hospital even walked into the showroom and bought the first unit off the floor to clean synthetic turf. That sale happened before the shop could even film it. Another unit was ordered so it could be tested on camera.

Spoiler: it is not the ideal synthetic turf cleaner for every situation, but it shines in many other jobs.

This review and demo comes from the team at Main Street Mower, a Central Florida mower and equipment shop. They also sell online to most of the US. You can pick up the KGA 770 or other gear through the Main Street Mower online store, and those purchases support their content.

The KGA 770 is simple to use, even if you have never touched a sweeper before. It feels like pushing a big, smooth rolling push mower that picks up debris instead of cutting grass.

Here is what you work with:

• Height of brush setting: A knob lets you raise or lower the brush. The crew points out that the tool is built more for hard surfaces, so when they move onto thick synthetic turf, they set the brush higher.
• Battery slot: It uses a Stihl AP battery that powers the brushes.
• Gear drive from rear wheels: The brushes are not only powered by the battery. They are also gear driven by the rear wheels as you push. The battery simply makes them spin faster and reduces resistance, so the tool feels lighter and more responsive.
• Front brushes and hopper: As you push, the brushes sweep debris into a front hopper, where all the material is stored until you dump it.

Using the KGA 770 looks a lot like this:

1. Insert a charged AP battery into the machine.
2. Set the brush height for your surface, higher for thicker turf, lower for hard surfaces like concrete.
3. Push it forward so the rear wheels engage the gears and the powered brushes start sweeping debris into the hopper.

The machine also has a rear third wheel that acts like a built-in wheelie bar. When you tilt the unit back to move or reposition it, that wheel helps keep the base from scraping and prevents wear on the bottom of the hopper.

In their words, it is basically a giant push broom with a dustpan, electric powered.

The first major test takes place on synthetic turf at Winter Garden Little League. A hospital had bought their first KGA 770 to clean turf, so the team wanted to see how well it actually performs on that type of surface.

They start along the edge of the synthetic turf, where there is thatch buildup and loose debris.

• On the first pass, the sweeper grabs about half the material.
• On a second pass along the same line, it picks up most of what was left.

From above, it looks like the brushes are sweeping everything and feeding it into the machine. However, some debris clings to the plastic turf and to the sweeper itself.

This is where something interesting happens.

The team notices a static charge building up on the turf and machine. As plastic brushes rub against plastic turf, friction builds a charge, similar to rubbing PVC or plastic pipes together.

Because of that static, a bit of debris gets kicked back out near the hopper opening instead of staying inside. They point out that this is not normal on other surfaces and appears to be specific to this synthetic turf situation where you have plastic on plastic.

So, while the sweeper picks up most of the thatch and edge material, there is a little bit of stray debris due to static.

To push the test further, they throw down random objects on the turf to see how the KGA 770 handles them. The machine does very well here and gets everything on the passes.

This is one of the early clues to what the sweeper is actually good at:

• Natural materials like grass
• Larger debris like trash, random objects, small sticks

Whenever there is a clear object sitting on top of the surface, the brushes seem to grab it easily and feed it into the hopper.

When they pull the hopper off and look inside, the result is described as “pretty crazy.” It picked up:

• A lot of grass
• Some of the little black rubber pellets from the turf infill
• A bit of synthetic thatch

The sweeper is very effective at taking loose grass clippings off the turf. It also pulls in some of the pellets, though that is a mixed result.

They point out that any system you use on this kind of turf, even a blower, will likely remove some of the infill pellets. It is hard to clean the surface without losing some rubber.

The final word on turf is clear:

• The KGA 770 is not at its best on synthetic turf as a full turf maintenance solution.
• It does work well when you have mulch, rocks, or bigger debris that has tumbled onto the turf, like the hospital that had mulch and stones spilled into synthetic grass.

In short, it will help with contamination on turf, but it is not a perfect fit for every turf task, and other surfaces suit it much better.

Next, they move to what turns out to be the KGA 770’s real sweet spot. The Little League has playoffs that night, and the crew has a couple of hours to clean bleachers, concession areas, and sidewalks.

This setting fits how most people will actually use a sweeper like this.

They bring a backpack blower to work alongside the KGA 770.

The plan:

• One person uses the blower under the bleachers and around obstacles to push debris into the middle aisle.
• The operator with the KGA 770 walks down the middle aisle and sweeps everything into the hopper.

That combination works well for several reasons:

• Bleachers and tight spots trap debris that is hard to reach with a push sweeper alone.
• The blower moves trash, dust, and leaves out into the open.
• The KGA 770 collects everything in the hopper so it does not just pile up somewhere else.

They collect rocks, sticks, trash, and general buildup that had been pushed into corners over time.

On fields like this, much of the cleanup is done by volunteers or board members who have limited time. These folks are not paid staff, and they may be working in the evening during or after games.

A few advantages stand out:

• The KGA 770 is quiet, so fields can be cleaned even while games wrap up.
• It is less tiring than sweeping everything by hand with a wide push broom.
• Instead of just blowing trash into the grass or parking lot, you actually remove the debris and dump it in a trash can or trailer.

With a blower only, debris always moves from point A to point B and has to land somewhere. With the sweeper, you go on to point C and actually haul it off.

When the hopper is full, they tilt the machine back, roll it, and dump the load. The hopper can get very heavy after a long pass under bleachers and over dirty sidewalks.

That rear third wheel becomes helpful here because you often tilt the tool back to reposition it. It protects the bottom of the hopper from scraping.

After the bleacher cleanup, they find a little moss and some fine material wrapped around the brushes. It looks similar to cleaning hair from a vacuum at home.

That tells you a couple of things:

• You will need occasional maintenance to untangle stringy material or moss.
• Shorter materials, like hair in a barbershop, would likely be easy work for it.

One of the crew jokes that this would be interesting to see in a barbershop, sweeping up hair all day.

Battery performance is one of the bright spots in this review.

They used the KGA 770 for about 45 minutes in real conditions and the battery dropped only one bar out of four. That is with a battery that is already a few years old and used as a demo unit around the shop, not a brand new pack.

For a sweeper that is pushing against turf, sidewalks, and bleacher debris, that is impressive. The team calls the runtime pretty incredible.

The machine can also store upright, which saves space when you keep it in a trailer, shop, or small storage area.

By the end of the test, it is clear that the KGA 770 solves problems in a lot of settings.

Here are some places where this sweeper fits very well:

• Ball fields and sports complexes
• Schools and high school cafeterias
• Lunchrooms and indoor common areas
• Theme parks and attractions
• Stadiums and arenas
• Warehouses and manufacturing floors
• Festivals, carnivals, and arcades
• City sidewalks and downtown walkways
• Big box store floors like Lowe’s
• Barber shops for hair cleanup
• Properties with lots of acorns

Acorns get special mention. They are round, slick, and hard to pick up. Many vacuums have trouble with them, and blowers just scatter them around. The crew points out that this sweeper would absolutely pick up acorns and that people have been searching for a good acorn solution for a long time.

The sweeper is also quiet enough that board members or staff can run it on a field or campus in the evening without bothering anyone.

You will need to detangle the brushes now and then, but that is similar to caring for a home vacuum.

They also compare the KGA 770 to traditional gas powered walk-behind vacuums. Those machines are powerful, but come with tradeoffs:

• They cost around $3,000 to $5,000.
• They are loud and dusty.
• They have carburetors, burn gas, and need oil changes and regular service.

The KGA 770 costs less, runs on battery, and avoids many of those headaches.

Here is a simple comparison:

The KGA 770 is not a perfect replacement for every gas vacuum job, but for many sidewalks, floors, and open areas, it gives crews a quiet and cleaner option.

The team is clear on this point:

• The KGA 770 does not replace a backpack blower. They still needed air for the final polish on the Little League property.
• A blower can reach places the sweeper cannot and is better at moving light debris off rough surfaces or out of deep corners.

The tools complement each other. The blower moves debris into open areas, and the sweeper gathers it up and removes it for good.

You will also still want a regular broom for tight nooks and spaces the sweeper cannot reach. That said, for daily or weekly care of open areas, the KGA 770 can keep things tidy so you are not always grabbing a broom and dustpan.

You can also do quick passes and leave the debris in the hopper for a while. It can sit there until the hopper is full and ready to be dumped.

One of the strongest points in favor of the KGA 770 is that it has Stihl’s support network behind it.

There are other sweepers on the market that look similar, but they may not have:

• Easy access to replacement worm gears
• Replacement bristles and brushes
• New hoppers or buckets

With Stihl, those parts are available through dealers all across the country, as well as online. If something wears out over time, you are not stuck hunting for obscure parts.

You can buy the Stihl KGA 770 battery powered sweeper directly from Main Street Mower through their product page for the KGA 770, along with batteries, chargers, and other Stihl parts.

After a full day on turf, sidewalks, bleachers, and dusty walkways, a clear picture forms.

• Picks up a wide range of debris: grass, rocks, trash, random objects, and likely acorns.
• Quiet and battery powered: suitable for evening work and indoor or near-indoor spaces.
• Excellent runtime: about 45 minutes of hard use only dropped one bar on a used battery.
• Versatile: useful for homeowners with large driveways or patios, as well as schools, cities, and contractors.
• Strong support: parts and service access through the Stihl dealer network and online shops.

• Synthetic turf is not its best surface for full maintenance, due to static and pellet loss.
• It cannot replace a backpack blower for final finishing or reaching tight areas.
• Brushes can pick up stringy material and need to be cleaned at times, similar to a household vacuum.

In the crew’s own words, “This machine is a giant push broom with a dustpan made on electric powered.” It fills the gap between simple hand tools and expensive gas powered vacuums.

If you want to add that kind of tool to your setup, you can find the KGA 770 and other Stihl equipment through the Main Street Mower online store.

The Stihl KGA 770 is not magic and it does not replace every blower, vacuum, or broom on your trailer. What it does offer is a smart way to keep large areas cleaner with less labor, less noise, and less dust floating around.

It shines on hard surfaces, walkways, bleachers, shops, and anywhere you would normally spend a lot of time pushing a broom. Pair it with a backpack blower and you get a fast, efficient cleanup system that actually removes debris instead of just moving it.

If you can already picture spots on your property or in your business where this sweeper would save time, it is probably a good fit. Thanks for reading, and if you have your own ideas for where a tool like this could work, share them and help others get some new cleaning strategies in mind.
