Jetting and vacuum (Jet vac) tankers are the ultimate multi-purpose vehicle, combining high-performance jetting and suction pumps to service a wide variety of drain, sewer and gully cleaning tasks in a single visit.

In modern jetvac combination vehicles, pump performance is pivotal, and with the development of new technologies, the capacity of smaller units is now similar to that of larger vehicles. Compact jet vac tankers, such as the 7.5t Riocom, can be driven without an HGV license (for those in the UK with a driving licence that pre-dates 1997) and offer ample power to undertake a range of jetting and vacuum tasks. For example, the RioCom offers a high-pressure jetting capacity of 2200psi @ 22gpm and suction capabilities of approximately 1800gpm.

Our Guide to Vacuum & Combination Units


Over recent years, more contractors are embracing technology and are investing in smaller combis as a way to make their businesses leaner and more streamlined, with savings in fuel economy, outlay and single-man operation. Whilst larger tankers, such as the 10 or 12 tonnes FlexCom, have the main advantage of tank capacity over smaller units, new Low and Ultra-Low Emission Zones introduced in cities including London are restricting the use of these vehicles in certain areas.


With a variety of combination units to choose from, you may be left wondering “which jet vac tanker is right for me?” Our handy guide below explains the different types of jetting and vacuum units:

4x4 Jet Vac Combination Vehicles

Designed for use in areas with restricted height access, jet vac tankers can now be mounted on a 4x4 chassis. These combi units, including the UrbanCombi, cope well with difficult terrain and offer high-performance pump and vacuum capabilities ideal for emptying grease traps and wells.


Suction Trailer Units

Trailer units can either be fixed to a customised frame with excellent road handling or to a trailer, meaning that they can be easily stored on-site. With multiple suction and tank capacities available, they are most commonly used for clearing septic tanks, FOGs (Fats, Oils and Grease) and flooded basements, and to prevent corrosion, often undergo pre-treatment.


Small Jet-Vac Combination Tankers

Suited for use in narrow and congested areas, smaller jet vac tankers, such as the RioCom and Unicom, are becoming increasingly popular with contractors, with their liveries a fantastic way of promoting businesses. With separate tanks for clean and wastewater, these compact tankers have powerful jetting and vacuum capabilities and can be fixed to a 4.5t or 7.5t chassis. Similar to 4x4 combination units, these small jet vac combis are LEZ and ULEZ compliant, with engineers also able to operate the vehicles without an HGV License. Read the case study into a fleet of RioCom’s supplied to service a contract with Severn Trent.


Large Jet Vac Trucks

Anything between 10t and upwards of 25t is classed as a large jet vac tanker. Able to operate in pipe diameters up to 600mm, the main draw of these vehicles is their ability to carry and remove more water, with tanks able to hold between 3500 and 12,500 litres of clean/ wastewater compared to approximately 3000 litres in smaller tankers. Pivoting hydraulic hose reels, bespoke tank partitions and five or seven-channel radio remote control systems are all high-level, sophisticated features that can be found on and added to these tankers.
