A 6×6 Super Sucker truck is not the right answer for every sewer-cleaning job. For routine municipal work on paved roads, a smaller combination unit is often easier to operate, easier to park and less expensive to run.
This type of machine starts to make sense when the site is less forgiving: rough access roads, loose ground, long hose runs, difficult material and a crew that needs to wash and recover material through the same shift. It is a working configuration for contractors and municipal teams whose normal truck is no longer keeping up with the job.
The reference vehicle discussed here combines a 10,000 L waste tank and a 7,000 L clean-water tank on a 6×6 heavy-duty chassis. It also pairs a high-output vacuum system with a 330 L/min high-pressure jetting system. The figures are useful, but the important question is still simpler: will this configuration make the operator's day easier, or merely make the vehicle larger than necessary?
Start with the job, not the tank size
From the factory side, we would not recommend a 6×6 Super Sucker simply because a buyer asks for the largest tank or the highest airflow. A truck like this earns its place when several requirements come together.
It is worth considering when the crew regularly works away from paved roads, needs to approach construction sites, drainage channels, industrial yards or sandy areas, and cannot rely on a standard 4×2 or 6×4 truck getting close to the work. The 6×6 layout is about access and traction. If the truck will spend its whole life on dry, wide urban roads, that extra driveline can be unnecessary weight and cost.
The same is true of the combined system. A normal suction truck can be the better choice where the job is only collecting wastewater or sludge. A combined heavy-duty vacuum jetting truck becomes more useful when the operator must first break up or flush a blockage, then recover the resulting material before moving to the next location.
For a broader comparison of the two working methods, see Combination Jetting and Vacuum Truck vs Sewage Suction Truck.
When this 17,000 L 6×6 configuration is a sensible fit
This reference 6×6 Super Sucker truck is aimed at operations with a demanding working cycle, not occasional light cleaning. It can be a sensible direction where the operator needs all of the following:
- Poor site access or soft ground. Six-wheel drive helps when reaching remote sewer lines, treatment areas, construction sites or unpaved service roads is part of the job.
- Continuous jetting and recovery. The truck carries 7,000 L of clean water for jetting and 10,000 L of recovered material, so the crew can clean and collect without treating the two tasks as separate jobs.
- Longer cleaning runs. The reference has a 120 m DN25 high-pressure hose on a hydraulically driven reel, plus a 20 m auxiliary DN13 hose and hand spray gun.
- Heavy suction work. The stated Jurop Roots vacuum system is rated at 4,150 m3/h and is paired with a DN150 suction boom and 10 m heavy-duty suction hose.
- A more severe climate or operating environment. The source configuration includes electrophoretic coating, epoxy internal tank protection and a stainless-steel waterproof control box. These details matter where heat, moisture, salty air or difficult water quality shorten the life of ordinary equipment.
No single point on this list is enough by itself. What usually justifies this kind of truck is the combination of bad access, high daily output and a need to wash and recover material in one visit.
What the 10,000 L waste tank and 7,000 L water tank mean in practice
The split is deliberate. A combined sewer-cleaning truck has to carry enough water to do useful jetting work, while leaving enough room for the material recovered from the line. On this reference unit, the total capacity is 17,000 L: 10,000 L for wastewater or collected material and 7,000 L for clean water.
That is a more practical arrangement for crews that are clearing blocked lines, washing a section of network and recovering liquid, sludge or debris afterwards. It is not a claim that every job will use the full 10,000 L waste volume. Thick sludge, sediment and high-solids material can change the legal payload and working volume quickly. The actual material, local axle limits and disposal route should always be checked before the tank split is finalised.
The reference tank uses Q235 carbon steel, with a 6 mm shell, 8 mm heads and a hydraulically operated rear cover. It also lists pressure and vacuum relief protection, secondary anti-overflow protection, internal coating and a tank partition designed to support unloading pressure. These are the parts operators notice later, when the truck is being cleaned, discharged and maintained rather than photographed.
If the material is corrosive, saline, chemical or unknown, a carbon-steel tank should not be assumed to be the final answer. The tank material, coating, valves and seals need a separate discussion. Our Carbon Steel vs Stainless Steel Vacuum Tanks guide explains the main choice.
Suction power is useful only when the whole suction route is right
The supplied reference lists a Jurop Roots vacuum system with stated airflow of 4,150 m3/h, a 6-inch stainless-steel inlet and outlet, and a 10 m DN150 heavy-duty suction hose. The boom can rotate through 270 degrees and is intended to carry DN150 hose.
Those numbers describe a serious suction arrangement, but they are not a shortcut around site conditions. A high-capacity blower still has to work through the actual hose route, lift height, hose diameter, material density and filter condition. Recovering thin wastewater through a short, straight hose is very different from lifting thick sludge through a long line with several bends.
This is why a useful enquiry includes the normal suction distance, the vertical lift, the material being collected and whether solids are expected. For the underlying selection logic, see How to Choose a Vacuum Pump for a Sewage Suction Truck.
The jetting side is designed for more than a quick washdown
The high-pressure side of this reference uses a Pinfu X0330 pump rated at 330 L/min and 180 bar. It has a 120 m high-pressure hose on a hydraulic reel with automatic hose guidance, along with remote operation and a separate 20 m auxiliary hose with hand spray gun.
For a sewer-cleaning crew, flow rate is often as important as pressure. Pressure helps the nozzle work against a blockage; water volume helps carry loosened material along the pipe. A 330 L/min system is intended for substantial cleaning work, not just washing the outside of a tank.
The full-power transfer case in the documented configuration is intended to allow vacuum and jetting functions to operate independently or together. That matters when a crew needs to keep cleaning a line while recovering the water and material that comes back. It is one of the reasons this is better described as a heavy-duty vacuum jetting truck than a standard suction vehicle with an auxiliary washer.
When we would recommend a smaller truck instead
There is no advantage in sending a 45-ton-class 6×6 configuration into a route that does not need it. A smaller combined unit is usually a better fit where access is narrow, work is mainly urban, the pipe-cleaning runs are short or the team only needs occasional suction.
Likewise, an operator whose work is mainly septage collection or routine wastewater removal may be better served by a dedicated vacuum truck. The extra water tank, high-pressure pump, reel and 6×6 driveline add cost and maintenance. They should solve a real problem, not just make the quotation look more impressive.
For medium-scale suction work, compare the 10-12 m3 sewage suction truck configuration guide. For a larger but more conventional vacuum-only direction, see 20 m3 Heavy-Duty Vacuum Suction Truck: What to Check Before Ordering.
The configuration points to settle before ordering
Once a buyer has established that a 6×6 Super Sucker is justified, the useful next step is not to copy a specification sheet unchanged. It is to confirm the parts that affect the daily work:
- Ground and route conditions: how much of the route is paved, how soft the site becomes after rain, and whether full 6×6 traction is genuinely needed.
- Material to be handled: wastewater, sewer sludge, industrial liquid, sand-bearing slurry or another medium. This affects tank material, filtration and hose choices.
- Cleaning duty: pipe diameter, usual hose length, blockage type, desired nozzle package and the amount of water required per shift.
- Suction duty: normal hose length, vertical lift, solids content and required recovery rate.
- Destination-market requirements: chassis emissions, left- or right-hand drive, road limits, language markings, climate protection and after-sales parts support.
- Discharge method: where the material is discharged and whether rear-door opening, pressurised discharge or another arrangement is appropriate.
That information lets the factory adjust the tank split, chassis, pump package, hose system, protection and controls around the job rather than treating this 17,000 L reference as a fixed product.
A heavy-duty tool for a specific kind of work
This 6×6 Super Sucker truck is a credible choice for an operator who needs to reach difficult sites, clean lines with a high-output water system and recover substantial material without breaking the working cycle into separate vehicles.
It is not intended to replace every sewer-cleaning truck in a fleet. Its value comes from taking on the jobs that smaller units struggle to reach or complete efficiently. If you share the material, pipe sizes, access conditions, usual hose distance and destination market, CLW Group can use this reference as a starting point and recommend whether a 6×6 configuration is warranted.

Frequently Asked Questions
Is a 6×6 Super Sucker truck necessary for ordinary urban sewer cleaning?
Usually not. If the work is mainly on paved roads with short cleaning runs, a smaller 4×2 or 6×4 combination truck is often easier and more economical to operate. A 6×6 layout is most useful where traction and access are real problems.
Can this truck jet and vacuum at the same time?
The reference configuration lists a full-power transfer case intended to support independent or simultaneous jetting and vacuum work. The final operating arrangement should be confirmed with the selected chassis and pump package.
Is the 10,000 L waste tank suitable for thick sludge?
It can be used for sludge work, but the practical payload depends on the material density, solids content and local axle-load limits. Thick material must be assessed by weight as well as tank volume.
Is the carbon-steel tank suitable for corrosive industrial liquid?
Not automatically. The reference includes coating protection, but corrosive, saline or chemical media may call for different tank material, lining, valves and seals.
What information should be sent for a configuration recommendation?
Send the working material, pipe sizes, normal suction distance and lift, site access conditions, daily work volume, destination country and any preferred chassis direction to CLW Group.
