Rothenberger R 90
Versatile 90 bar pressure with excellent hose management.

|---|---|---|---|---|
| R 50 | Light maintenance | 50 bar / 725 PSI | 10 L/min | 14 kg |
| R 90 | Versatile pro use | 90 bar / 1305 PSI | 15 L/min | 19.5 kg |
| R 160 | Heavy blockages | 160 bar / 2320 PSI | 20 L/min | 28 kg |

Rothenberger R 90
Best OverallPros
- Excellent balance of power and portability
- Automatic hose reel for easy retraction
- Robust frame with good stability
Cons
- Hose can kink if not stored properly
- Nozzle selection could be wider out of the box
The R 90 is the most popular model in the Rothenberger lineup for good reason. With 90 bar of pressure and a 15 L/min flow rate, it handles most residential and light commercial blockages, from kitchen sinks to main drains. The automatic hose reel is a standout feature, saving time on setup and pack-down. Owner reviews consistently praise its reliability and the ease of replacing the hose if needed.
However, some users note that the included nozzle set is basic. For tougher jobs like root intrusion, you will need to purchase additional nozzles. The unit is also on the heavier side for a machine in this class, but the large wheels and sturdy handle make it manageable on site.
Rothenberger R 160
Best for Heavy BlockagesPros
- High pressure cuts through grease and roots
- Long 30 m hose for deep runs
- Durable pump with low maintenance
Cons
- Very heavy at 28 kg
- Requires a high water supply flow rate
The R 160 is a serious machine for serious blockages. Its 160 bar pressure and 20 L/min flow can break up hardened grease, scale, and small tree roots that would stop smaller units. The 30 m hose allows access to deep sewer lines, and the pump is built for continuous professional use. Aggregated reviews from trade users highlight its ability to clear jobs in a single pass.
The main drawback is its weight and size. At 28 kg, it is a two-person lift to load into a van. It also needs a good water supply; a garden hose with low pressure will starve the pump. This is a machine for the dedicated drain specialist, not the occasional user.
Rothenberger R 50
Best Budget / Light DutyPros
- Lightweight and easy to transport
- Simple controls for quick setup
- Good for preventative maintenance
Cons
- Not powerful enough for tough blockages
- Short hose limits reach
The R 50 is the entry point to the Rothenberger drain jetter range. With 50 bar pressure, it is effective for clearing slow drains, flushing out debris, and maintaining clean pipes. It is significantly lighter than the larger models, making it a good choice for a property manager or a DIY enthusiast with a large home. Owner reviews note it is very reliable for light use.
Its limitations become clear on tougher jobs. It will struggle with compacted grease or root ingress. The 15 m hose is also restrictive for anything beyond a standard house run. For the price, it is a solid machine, but be realistic about what it can handle.
Rothenberger R 200
Best for Industrial UsePros
- Extreme power for the toughest blockages
- Very long hose for deep industrial lines
- Professional-grade pump with long service life
Cons
- Very expensive
- Requires a van or trailer to move
The R 200 is the flagship model in the Rothenberger range, designed for industrial and municipal drain cleaning. Its 200 bar pressure and 22 L/min flow can handle the most stubborn blockages, including concrete scale and heavy root masses. The 40 m hose allows access to deep manholes and long sewer runs. Aggregated reviews from municipal contractors rate it as extremely reliable and powerful.
This machine is overkill for most residential or even commercial jobs. It is large, heavy, and expensive. It also requires a three-phase power supply in some configurations. It is a specialist tool for a specialist job.
Rothenberger R 70
Best Mid-Range AlternativePros
- Lighter than the R 90
- Good pressure for most domestic jobs
- Compact footprint for storage
Cons
- No automatic hose reel
- Flow rate is lower than ideal for some blockages
The R 70 sits between the R 50 and R 90. It offers 70 bar of pressure, which is enough for most domestic blockages, including kitchen and bathroom drains. It is lighter than the R 90, making it easier to carry down stairs. Owner reviews mention it is a good compromise for those who find the R 50 underpowered but do not need the full capability of the R 90.
The lack of an automatic hose reel is a notable omission at this price point. The 15 m hose is also a limitation for longer runs. It is a solid machine, but the R 90 offers better value for a small increase in budget.
What to check before buying a drain jetter
Before purchasing a Rothenberger drain jetter, consider the following factors to ensure you choose the right model for your needs.
Pressure and flow rate. Pressure (measured in bar or PSI) determines how well the jetter can break up blockages. Flow rate (litres per minute) determines how effectively it flushes debris away. For most domestic jobs, 70-90 bar and 12-15 L/min is sufficient. For commercial or industrial work, 160 bar and above is recommended.
Hose length and diameter. The hose length determines how far into the drain you can reach. A 15 m hose is fine for a standard house, but 20-30 m is needed for longer runs or commercial buildings. The hose diameter should match the nozzle size for optimal performance.
Water supply. Drain jetters require a constant water supply, typically from a garden hose. Larger machines like the R 160 and R 200 need a higher flow rate from the tap. Check your water pressure and flow rate before buying a high-powered model.
Portability and storage. Consider the weight and size of the machine. The R 50 is relatively portable at 14 kg, while the R 200 is a heavy unit that requires a van. Ensure you have adequate storage space and a way to transport the machine to job sites.
Mistakes to avoid when using a drain jetter
Using a drain jetter incorrectly can cause damage to pipes or injury. Avoid these common mistakes.
Using too much pressure. High pressure can damage old or fragile pipes, especially clay or cast iron. Start with a lower pressure and increase only if needed. Always check the pipe material before jetting.
Not using the correct nozzle. Different nozzles are designed for different tasks. A forward jetting nozzle is for cutting through blockages, while a rear jetting nozzle is for flushing. Using the wrong nozzle reduces effectiveness and can damage the hose.
Forgetting to lubricate the hose. The hose needs to slide easily through the drain. Apply a suitable lubricant to the hose before insertion to reduce friction and prevent kinking. This also extends the life of the hose.
Neglecting maintenance. Drain jetters require regular maintenance, including cleaning the filters, checking the oil level, and inspecting the hose for damage. Follow the manufacturer's schedule to keep the machine running reliably.
