Trailer Jetters vs Cart Jetters vs Skid Jetters: How to Choose the Right Jetter

So you’ve been researching jetters, asking all the right questions, and hearing a lot of different opinions about what you should run, size, GPM, PSI, brand, and everything in between. At Jetters Northwest, we have these conversations every day with contractors trying to match the right equipment to the work they actually do, not just what looks good on paper. 

We’ve covered GPM and PSI in another article, so instead of rehashing that debate, let’s focus on something just as important: which type of jetter actually fits your day-to-day work and business model.

When it comes down to it, most contractors are deciding between three main jetter types:

• Portable cart jetters
• Trailer jetters
• Mounted skid jetters, often called van packs

The short answer is simple: buy what works for you and your business. Below, we break down the real-world pros and cons of each option, including some considerations you may already know and a few that often get overlooked.

Jetter Type Comparison at a Glance

This comparison helps narrow your options quickly. Below, we dig into each jetter type in more detail so you can match the equipment to how you actually work.

Portable Cart Jetters

Portable cart jetters are often the entry point into jetter ownership, and for many operations, they may be all you ever need. They’re easy to care for, transport, and store, and they don’t require a permanent home inside a service vehicle. Take them when you need them, leave them behind when you don’t.

Pros of Cart Jetters

• Relatively inexpensive to buy and own
• Easy to operate and move between multiple trucks
• Do not take up permanent space in a service van
• Today’s cart jetters are far more capable than many people expect

Modern cart units, like higher-output models running around 9 GPM at 4000 PSI, are fully capable of powering through tree roots, grease, and tough buildup in up to 6-inch pipe when used correctly. For many contractors, that level of performance covers the majority of residential and light commercial work.

Cons of Cart Jetters

• They may not be with you all the time, which can make it harder to sell jetting jobs that need to be done immediately
• Larger industrial or facility clients may perceive trailer or mounted units as more “professional,” even if the cart jetter is just as capable
• Typically require loading and unloading for each use, often needing a lift gate, crane, ramps, or extra manpower

While these may not be drawbacks for every operation, they are important factors to weigh when deciding how you want to deploy jetting services.

Trailer Jetters

Once you move into trailer jetters, customers often assume you are serious about jetting, and perception does play a role here. A trailer-mounted jetter can become part of your company’s image, signaling capability and preparedness before you ever step out of the truck.

Beyond appearances, trailer jetters offer practical advantages that can open the door to larger and more demanding jobs.

Pros of Trailer Jetters

• Typically start where cart jetters leave off, with common contractor models producing 8–9 GPM at 4000 PSI and scaling up to 20 GPM or more
• Higher flow rates allow the use of advanced nozzles that are not functional on smaller jetters, especially those requiring 12 GPM or higher
• Onboard water tanks allow you to carry water to and from the jobsite when supply is limited or when you want to minimize use of customer utilities
• Can be towed by different vehicles and operated by different technicians, making them flexible for subcontracting or shared use

For municipal and sewer district work, even higher GPM configurations are common, but many contractors find mid-range trailer jetters ideal for heavy commercial and industrial cleaning.

Cons of Trailer Jetters

• Towing, parking, and positioning can be challenging in tight or urban areas
• Some regions have towing restrictions or regulations that limit where trailers can be used
• Operators often work farther from the jetter controls, making remote flow controls or two-person crews more common
• Require dedicated storage space, and without heated indoor storage, freeze protection becomes critical in winter months

Trailer jetters are powerful and versatile, but they do require more planning and space to operate efficiently.

Mounted Skid Jetters (Van Packs)

Mounted skid jetters, often referred to as van packs, have become increasingly popular and are now the preferred option for many drain cleaning contractors. The biggest advantage is simple: they’re always with you.

Having a jetter permanently mounted in a dedicated vehicle makes jetting jobs easier to sell and easier to deploy. Even when a mounted unit is similar in size to a portable cart, customers tend to view it differently because you’ve committed an entire vehicle to the task.

Pros of Mounted Skid Jetters

• Always available, which helps convert jetting opportunities on the spot
• Can carry water to and from jobs, similar to a trailer, though usually in smaller quantities
• Compact models can still offer strong performance, with some units available up to 12 GPM to run a wide range of jetting tools
• Wireless Remote Control is a popular feature on many mountable jetters, making for highly efficient jetting while away from the van.
• Ideal for operations with multiple trucks and technicians, allowing jetting capability across the fleet

Mounted jetters are often used to restore flow quickly, clearing blockages and buildup from various pipe sizes and applications. Van pack types have a compact footprint that typically leaves plenty of room in the van for your cameras, snakes, flex-shafts, shelving, etc.

Cons of Mounted Skid Jetters

• The truck and jetter are tied together, so if either needs service, both might be out of commission
• For models without Wireless Remote Control, jetting indoors or at a distance from the van often requires portable hose-reels with manual-valve controls, or a second technician
• Performance scales with size; compact skids in the 8-12 GPM range can take on all kinds of commercial/residential jobs, but if you want 16 - 20 GPM capability then the skid will likely take up most of the van's cargo area, or require a larger box-van.

The Bottom Line

Jetters come in many configurations for a reason, because one size does not fit all. Portable carts, trailer jetters, and mounted skid units each serve a purpose depending on your workload, customers, crew size, and how you want to operate day to day. Many contractors have multiple jetter types - from small electric-powered units to carts to van-packs to trailers - to handle various jobs with techs of various skill-levels.  This is why we build all jetter types - to meet all of your needs.
