I’ve been using my Kranzle K10/122 TS for the past year and thought it was about time I made a proper review about it on here. In this article I’ll take you through the accessories, performance, pros and cons of the machine, and compare it to some alternatives.
Prefer to sit back and relax instead of read? Here’s my YouTube video review of this pressure washer on the Auto Care HQ channel.
Performance
This Kranzle K10 has an operating pressure of 30-120 bar, which can be adjusted using the red dial on the side. It also has a flow rate of 10 litres per minute which is much higher than most other options on the market.
This high flow rate gives the pressure washer more power and makes it more effective at shifting dirt, but without putting too much pressure on the panel.
This is of course more than enough power and performance for cleaning vehicles and getting excellent quality snow foam. I’ve also used it for cleaning patios and again it works fantastically and is a huge step up from the Karcher K4 that I was previously using.
Design & Specifications
Here’s a quick rundown of the specifications of the Kranzle K10/122 TS:
- 44 cm (L) x 20 cm (W) x 33 cm (H)
- 23 kg weight
- Brass pump and stainless steel valves
- M22 connection for the hose
- 5 meter mains cable
- Adjustable dial to control the pressure (between 30-120 bar)
- Metal handle and legs with a rubberised grip
It’s also worth noting that this model is the “Automatic” version, as denoted by the “TS” in the model name which stands for “total stop”. This means that the motor stops running whenever the trigger isn’t being pulled. There is also a “Standard” version which is around £50-75 cheaper and does not have this feature.
Accessories

There are three accessories which come with the machine:
- Hose – there is an option of a 10m, 15m and 20m hose
- Trigger – there is an option of a long or short trigger, and an M22 or quick release fitting (note this is not a standard 1/4 quick release connection)
- Nozzle: you get the choice here between a stubby nozzle and a long nozzle
The accessories on the Kranzle machines are miles better than you’ll find on cheaper alternatives such as Karcher and Nilfisk.
However, I do still prefer my aftermarket MTM SGS35 Short Trigger and Carscope nozzles compared to the stock Kranzle options.
I do use the stock Kranzle hose though as it’s excellent quality, lies flat and doesn’t kink up. I personally went for the 20 meter hose.
How Loud is It?
This Kranzle K10 is loud, there’s no denying it. It’s rated to 90 dB and for comparison, my Karcher K4 measured around 94 dB. However, the Kranzle does actually sound louder as the motor produces a pretty high pitched sound.
Make sure you check the YouTube video at the start of the article to hear what the motor sounds like.
If you have neighbours which are likely to whine about the noise level, then consider going for the Kranzle K7 instead. This has a lower flow rate (7 litres per min) but is a bit quieter at 84 dB.
Pros and Cons
Advantages of the Karcher K10/122 TS:
- The performance is excellent.
- It’s super compact for a pressure washer which puts out so much power, so it’s nice and easy to store.
- The steel braided and rubber coated hose is excellent quality. It lies flat and doesn’t kink up like cheaper alternatives.
- Very high build quality. It’s made to last and can be serviced and parts can be replaced.
Disadvantages of the Karcher K10/122 TS:
- This machine is very pricey, and you can expect to pay around £750-£800 depending on where you buy it and which accessory options you choose.
- It’s heavy at 23kg and a little bit difficult to carry (at least for me!)
- There’s nowhere to store the hose, and no retractable hose reel so it’s a bit inconvenient to wrap up and store the hose after use.
Comparing to Alternatives
Kranzle really are in a league of their own, and are highly regarded as industry-leading pressure washer manufacturers.
They’re expensive, but they’re an investment and are designed for last for a really long time. The same can’t be said for domestic alternatives from brands like Karcher which will need replacing much more frequently.
When I decided to upgrade from my Karcher K4, and settled on Kranzle as a brand, I was pretty confused by the different models in the range so I’ll quickly rundown the differences between them.
In the Kranzle professional-level line-up, you have the choice of the more expensive upright machines with an integrated hose reel, or the compact alternatives (like the K10).
There are 4 versions of the compact portable Kranzle pressure washers:
- K7/122
- K7/122 TS
- K10/122
- K10/122 TS
The “K7” and “K10” models run at the same pressure, but have different flow rates:
- K7 = 7 litres per min
- K10 = 10 litres per min
The K10 models offer better performance due to that increased flow rate, but the K7 models are best if you are running from a more limited water supply (e.g. a water tank). The K7 also is a bit quieter and has a lower power input and output so is a bit cheaper to run and more suitable for generators.
Now onto the K7 and K10 variants: “standard” and “automatic”.
- Automatic (TS or total stop) – the motor switches off automatically when the trigger isn’t being pulled
- Standard – the motor runs continuously when the machine is switched on, regardless of whether the trigger is not being pulled
The Automatic (TS) versions are about £50-£75 more expensive and of course have the benefit of switching that motor off when the pressure washer is not in use to reduce power consumption and noise.
However, the Standard versions are better if you are using a generator. This is because you don’t get repeated current spikes (whenever the trigger is pulled) which wear out the generator.
Here’s a table to summarise the difference between these four options.
| K7/ 122 Standard | K7/ 122 TS Automatic | K10/ 122 Standard | K10/ 122 TS Automatic | |
| Flow Rate | 7 litres/ min | 7 litres/ min | 10 litres/ min | 10 litres/ min |
| Power Intake | 1.6 kW | 1.6 kW | 2.5 kW | 2.5 kW |
| Volume | 83 dB | 83 dB | 90 dB | 90 dB |
| Stop/ Start Motor | No | Yes | No | Yes |
| Suitable for Generator | Yes | No | No | No |
| Suitable for Water Tank | Yes | Yes | No | No |

Conclusion
Overall I’ve been very pleased with my Kranzle K10/122 TS over the past year. The performance, quality and reliability is top-class and I’d have no doubts recommending this to fellow detailers.
The only real drawback is the price. But if you are looking to invest in a machine that will last a long time and outlive generations of cheaper alternatives, then the high price tag can be justified.
