Kranzle K7/122 vs K10/122 (TS and Standard) Models Explained

The Kranzle range can be pretty confusing and it can be difficult to understand the differences between each model and which one is most suitable for your requirements.

When I was looking into buying my Kranzle K10/122 TS, I put a lot of research into the differences between all the versions so I knew I was making the right choice. In this article I’ll be summarising everything I learnt to hopefully save you a bit of time!

4 Kranzle Pressure Washer Models

In the Kranzle portable series there are four variants:

K7/122 Standard
K7/122 TS (Automatic)
K10/122 Standard
K10/122 TS (Automatic)

There are two different main models of pressure washer (K7/122 and K10/122) and each of them have either a standard or TS (stands for “total stop”) version.

I’ll be going in-depth into the differences between these four pressure washers and explaining which model is best for different scenarios, but here’s a quick summary table to get started.

	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
Motor Speed	1400 rpm	1400 rpm	2800 rpm	2800 rpm
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 Small Generator	Yes	No	No	No
Suitable for Water Tank	Yes	Yes	No	No

Now let’s start by going through the differences between the K7 and K10 models, then I’ll go through the difference between the standard and automatic TS variants.

Kranzle K7 vs K10

The Kranzle K7 and K10 are the same price and have the same operating pressure (30-120 bar), but they have a different flow rate.

Kranzle K7 = 7 litres/ minute flow rate
Kranzle K10 = 10 litres/ minute flow rate

The flow rate of the pressure washer has a significant impact on the performance and with the K10 it is 40% higher compared to the K7.

So if the K10 is the same price as the K7, but offers better performance, then why would anyone choose the K7?

This is because the K7 is the best option if you have a limited water supply and are running the pressure washer from a water tank. This is the situation that many mobile detailers find themselves in.

The K10 is not suitable for use with a water tank and instead requires a mains water supply with a flow rate exceeding 10 litres per minute. It’s important to check that your mains water supply has a high enough flow rate before using the pressure washer. If the flow rate is not high enough, the machine will get damaged.

The K7 also has a different valve compared to the K10 which has a softer spring. This makes it better for use with a water tank.

There are also several other differences between the K7 and K10.

Motor Speed

The K7 has a slower motor compared to the K10.

K7/122 = motor speed of 1400 rpm
K10/ 122 = motor speed of 2800 rpm

Power Consumption

The K7 uses less power compared to a K10.

K7/122 = 1.6 kW power intake
K10/122 = 2.5 kW power intake

This is because the K10 requires more power to run the motor at a higher speed.

The extra power required for the K10/122 isn’t really an issue if you’re running from a mains supply (although it will cost more to use more electricity), but it can be a problem if you’re planning on using a generator as it’ll need to be quite large.

The K7/122 is the better option if you need to use a smaller generator for mobile car detailing.

Volume

Since the K7/122 has a slower motor compared to the K10/122, it is also quieter. This might be a consideration to make if you have close neighbours and you think the K10 might annoy them too much.

K7/122 runs at 83 dB
K10/122 runs at 90 dB

There’s a great video on the Kranzle Pressure Washer YouTube channel comparing the sound of the K10 and K7.

Similarities

Aside from the flow rate and motor, most of the specifications on the K7 and K10 are the same:

Operating pressure: 30-120 bar
Power cable: 5 meters
Hose: option of 10m, 15m and 20m
Dimensions: 44 cm x 20 cm x 33 cm (L x W x H)
Weight: 23 kg

Automatic TS vs Standard

There are two versions of the K7/122 and K10/122:

TS (total stop)
Standard

The TS version is also referred to as the “automatic” version, and the standard version is sometimes referred to as the “continuous running” version.

With the TS version, whenever the trigger isn’t being pulled, the motor will stop running.
With the standard version, the motor will run whether the trigger is being pulled or not.

You can tell the difference between the TS and Standard version by looking on the side of the machine. If the pressure washer has a small black plastic box, then it’s the total stop version.

Advantages of the Total Stop Version

Less noise (as the motor is only running when the pressure washer is in use)
Uses less power and saves electricity as the motor isn’t running constantly

Advantages of the Standard Version

Cheaper than the total stop model (by roughly £50)
Suitable for use with a generator

The TS version is not recommended for use with a generator.

This is because the TS version puts the generator under more stress as the motor is being turned on a far greater number of times (every time the trigger is pulled). Every time the pressure washer motor turns on, it causes the current to spike. Repeatedly spiking the current will cause the generator to wear out more quickly.

With the Standard version, the machine is only being turned on once (when it’s switched on at the back) so puts the generator under less stress.

The TS version will work with a generator, but it requires a very good power supply which can cope with the constant spiking. Hence, it’s better to use the Standard version instead where this isn’t a concern.

Which Kranzle Portable Model Should You Choose?

This depends on two things:

Water supply
Electricity supply

Here are the different scenarios and the most suitable Kranzle pressure washer for each situation.

Mains Water and Mains Power Supply = K10/122 TS Automatic

If you have no limits in terms of your electricity and water supply and will be using mains for both of them, then the Kranzle K10/122 TS Automatic pressure washer is the best option. The K10 offers a better flow rate compared to the K7 (at the same price) and the TS version saves electricity and creates less noise.

Here’s a link to the Kranzle K10/ 122 TS Automatic on Amazon.

If you have a mains water and power supply then you can run any of the four pressure washer variants.

Mains Water and Generator = K7/122 Standard

If you are using a mains water supply then you do have the option of either a K7 or K10, however if you’re using a generator then the less power-hungry K7 is the better option. The Standard version is much better than the TS Automatic version as it won’t put the generator under as much stress.

Here’s a link to the Kranzle K7/ 122 Standard on Amazon.

Water Tank and Mains Power Supply = K7/122 TS Automatic

If you are running from a water tank then the K7 is the only option. It’s a personal preference as to whether you want the TS or the Standard version if you have a mains power supply, but the TS version will use less electricity and create less noise so I think it’s the better choice.

Here’s a link to the Kranzle K7/ 122 TS Automatic on Amazon.

Water Tank and Generator = K7/122 Standard

This is a common setup for mobile car detailers. The K7 is the only option that’s suitable for use with a water tank, and the Standard variant is the most suitable for use with a generator as it won’t wear it out as quickly.
