What Size Magnetic Sweeper Do I Need?

One of the most common questions buyers ask is, “What size magnetic sweeper do I need?”

The answer depends on more than simply measuring the width of the truck, forklift, skid loader, or piece of equipment being used. Surface conditions, debris type, suspension height, turning radius, operating speed, cleanup frequency, and mounting style all affect what size magnetic sweeper will actually perform well in the field.

In many cases, choosing the wrong size sweeper leads to missed debris, poor maneuverability, operator frustration, or safety concerns during cleanup.

At Storch®, we help customers size SuperMag® magnetic sweepers for municipalities, airports, manufacturing plants, steel mills, military operations, scrapyards, construction sites, and industrial facilities across North America. The right size depends on the job, the surface, and how the sweeper will be used.

Wider Is Usually Better, Until Surface Conditions Change

Most buyers initially assume they should match the magnetic sweeper width to the width of their vehicle.

That is usually not the best approach.

In most applications, the magnetic sweeper should be wider than the tire track or wheel path of the machine. This is especially important during turns, where the rear wheels may track outside the front wheel path.

If the sweeper is too narrow, debris can remain directly in the tire path. That defeats the purpose of using a magnetic sweeper in the first place.

For this reason, many municipalities, contractors, scrapyards, and industrial facilities choose magnetic sweepers that extend beyond the wheel width of the truck, loader, forklift, or support vehicle.

However, wider is not always better.

If the sweeper is used on rough gravel, uneven dirt lots, heavily rutted surfaces, broken asphalt, or contoured terrain, an extremely wide sweeper may begin to bottom out or lose proper suspension height across uneven surfaces. In those environments, a slightly narrower magnetic sweeper may perform better overall because it can follow the surface more effectively.

The goal is not just maximum width. The goal is consistent pickup performance.

Common Magnetic Sweeper Sizes and Where They Fit

The Storch® SuperMag® lineup includes several common magnetic sweeper sizes designed around different applications.

48-Inch Magnetic Sweeper

A 48-inch magnetic sweeper is commonly used in manufacturing plants, welding facilities, maintenance departments, shipping areas, loading docks, and around dumpsters.

This size works well where maneuverability matters more than maximum coverage. It is a good choice for tighter indoor areas, smaller forklifts, and cleanup routes where operators need to work around equipment, columns, racks, and confined spaces.

72-Inch Magnetic Sweeper

A 72-inch magnetic sweeper is commonly used in auto recycling yards, scrapyards, industrial cleanup applications, construction areas, and rougher outdoor environments.

This size provides more coverage than a 48-inch sweeper while still maintaining flexibility on uneven surfaces. It is often a practical choice when the operator needs strong pickup performance but does not want an oversized sweeper that becomes difficult to maneuver.

88-Inch SuperMag® LT

The 88-inch SuperMag® LT is one of the most popular sizes for pickup trucks.

This model is designed to adapt directly to existing Boss® or Western® snowplow towers by replacing the plow blade with the magnetic sweeper assembly. This allows operators to quickly convert existing trucks into powerful debris collection vehicles.

For many municipalities, maintenance departments, and contractors, this is an efficient way to use equipment they already own.

96-Inch Magnetic Sweeper

The 96-inch SuperMag® is one of the most widely used sizes overall.

This size works well on municipal trucks, skid loaders, compact track loaders, and industrial cleanup equipment. It provides strong coverage while still remaining manageable on many uneven outdoor surfaces.

For many buyers, the 96-inch sweeper is the best balance between width, maneuverability, magnetic reach, and practical field use.

110-Inch Magnetic Sweeper

The 110-inch SuperMag® is commonly used for airports, airfields, military bases, large paved lots, and wide industrial cleanup routes.

This size is ideal when efficient debris collection over large surface areas is critical. For airfields and other high-risk areas, wider coverage can help reduce the number of passes required and improve cleanup efficiency.

14-Foot Magnetic Sweeper

A 14-foot SuperMag® is designed for large-scale industrial cleanup operations.

Common applications include steel mills, foundries, scrapyards, large outdoor manufacturing yards, and high-volume facilities where operators need to cover acreage efficiently.

This size is best suited for open areas where the support vehicle has enough room to maneuver and where coverage efficiency is a major priority.

Surface Conditions Matter More Than Most Buyers Realize

A magnetic sweeper operating on smooth concrete behaves very differently than one operating on gravel, dirt, grass, rough asphalt, or broken pavement.

On smooth surfaces, the sweeper can usually run closer to the ground with a more consistent air gap. On rough surfaces, the sweeper often needs to be suspended higher to avoid striking the ground.

That air gap matters.

The farther the magnet is from the debris, the harder it is to pick up steel. Many lower-cost magnetic sweepers lose pickup performance quickly once the distance from the ground increases.

One advantage of the Storch® SuperMag® design is its magnetic reach-out capability. The magnetic field is designed to remain effective even at suspension heights around five to six inches off the ground. That becomes extremely important on uneven surfaces where maintaining a perfect sweeper height is unrealistic.

This is also why properly engineered ceramic magnetic sweepers continue to perform well in many outdoor industrial applications. A strong, deep magnetic field often matters more than simply using the strongest magnet material on paper.

Match the Sweeper Size to the Vehicle

Vehicle size should strongly influence magnetic sweeper selection.

A compact forklift working in a plant aisle may need a smaller sweeper for maneuverability. A skid loader or compact track loader may work extremely well with a 96-inch sweeper because the unit can extend beyond the machine width while still maintaining good handling.

Municipal trucks often use 88-inch or 96-inch magnetic sweepers to cover wheel paths and improve roadway cleanup efficiency. Airports, steel mills, military bases, and large industrial yards often require 110-inch or larger sweepers because of the amount of surface area being covered.

When selecting a size, consider:

• Vehicle width
• Tire track width
• Turning radius
• Surface conditions
• Mounting height
• Sweeper suspension
• Debris type
• Debris volume
• Cleanup speed
• Operator visibility
• Safe cleaning and release

The correct sweeper size is the one that gives you enough coverage without creating handling, clearance, or safety problems.

Do Not Choose Based on Price Alone

One of the biggest mistakes buyers make is focusing only on the purchase price.

Many lightweight economy-grade magnetic sweepers are designed with simple manual release systems. These may require operators to physically pull debris off the magnet by hand or manually lift release handles under heavy magnetic load.

That creates real safety concerns.

Sharp steel debris can cause cuts, abrasions, puncture injuries, pinch injuries, and strained backs. This becomes especially dangerous when operators are collecting material such as:

• Nails
• Steel shards
• Machining scrap
• Welding wire
• Sheet metal offcuts
• Roofing debris
• Screws and fasteners
• Scrap fragments

Self-cleaning magnetic sweepers like the Storch® SuperMag® help reduce these risks by allowing safer debris release without direct operator contact with the collected metal.

This is one area where a higher-quality magnetic sweeper can pay for itself through improved safety, faster cleanup, and reduced labor.

Large Magnetic Sweepers Need Safe Cleaning Systems

Not all large outdoor magnetic sweepers are designed the same way.

Some magnetic sweepers use rotating magnetic systems that rely on physically rotating the magnet assembly to activate or deactivate the magnetic field. In some applications, this can create pinch points or awkward cleanup situations.

Large debris can become trapped between magnetic surfaces and surrounding steel structures, forcing operators into potentially hazardous manual cleanup.

As sweeper size increases, safe cleaning becomes more important.

A properly designed industrial magnetic sweeper should prioritize:

• Safe debris release
• Reduced pinch points
• Controlled magnetic disengagement
• Minimal operator exposure to sharp scrap
• Easy cleaning procedures
• Durable mounting and suspension
• Practical field serviceability

The bigger the sweeper, the more important these details become.

How to Choose the Right Magnetic Sweeper Size

The biggest magnetic sweeper is not automatically the best choice.

The right size depends on the application. For smooth paved areas, large lots, airfields, and wide cleanup routes, a larger sweeper may be the best option. For uneven yards, tight spaces, gravel areas, and indoor cleanup, a smaller or mid-size sweeper may perform better.

As a general guide:

These are general guidelines. The best size should always be based on the vehicle, surface, debris, and cleanup pattern.

FAQ: Magnetic Sweeper Sizing

Should a magnetic sweeper be wider than the vehicle?

In many applications, yes. A magnetic sweeper should usually be wider than the tire track or wheel path of the vehicle. This helps collect debris before the tires reach it, especially during turns where the rear tires may track differently than the front tires.

Is a wider magnetic sweeper always better?

No. A wider magnetic sweeper can cover more ground, but it may not be the best choice for rough, rutted, or uneven surfaces. If the sweeper is too wide, it may bottom out or lose proper suspension height. The best size balances coverage, ground clearance, pickup performance, and maneuverability.

What size magnetic sweeper is best for a pickup truck?

An 88-inch or 96-inch magnetic sweeper is commonly used for pickup truck applications. The 88-inch SuperMag® LT is designed to work with existing Boss® or Western® snowplow towers, making it a practical option for municipalities, contractors, and maintenance crews that already use snowplow-equipped trucks.

What size magnetic sweeper is best for a skid loader or compact track loader?

A 96-inch magnetic sweeper is often a strong choice for skid loaders and compact track loaders. It provides good coverage beyond the machine width while still remaining manageable in many industrial and outdoor cleanup environments.

Why does air gap matter when choosing a magnetic sweeper?

Air gap is the distance between the magnet and the metal debris. As that distance increases, pickup force decreases. This is why magnetic field depth is so important. A sweeper that works well close to the ground may not perform well if it has to be suspended higher on gravel, broken asphalt, dirt, or uneven terrain.

Final Recommendation

For many applications, the best magnetic sweeper is the one that balances coverage, maneuverability, magnetic reach, ground clearance, and safe cleanup.

A sweeper that is too narrow may leave debris in the tire path. A sweeper that is too wide may become difficult to maneuver or may not follow uneven surfaces properly. A low-cost sweeper may look acceptable at first but can create safety and performance issues once operators begin using it in real industrial conditions.

At Storch®, the SuperMag® lineup is designed around real-world industrial cleanup, not just catalog dimensions. Proper magnetic reach-out, safer self-cleaning systems, versatile mounting options, and durable construction all play a major role in choosing the correct magnetic sweeper size for the job.
