Disappointed !
There was no zero option otherwise I would have given that. It just worked for 5 minutes and motor stopped working. So disappointed with this purchase. I tried to take the air bubble out and then started again but no results.

Hello there.
The supplier has advised. Yes, a Hozelock hose and connector can fit on the Karcher K 4 Classic Home Pressure Washer. However, you will need an Hozelock adapter to ensure a proper connection. This adapter is essential for compatibility and will allow you to use the Hozelock hose effectively with your Karcher pressure washer.
Thank you for using Q&A
Hello Queried,
The supplier has advised the following for the Karcher K 4 Classic Home Pressure Washer - 1800W:
"To clarify, the product hierarchy and usage recommendations on the Karcher website are correct. Here is the accurate guide for our K-series pressure washers:
K2 and K3 models are designed for light to moderate-duty tasks. They are ideal for cleaning smaller areas such as garden furniture, bikes, and small patios.
K4, K5, and K7 models are designed for moderate to heavy-duty tasks. As the model number increases, so does the pressure and water flow rate. This makes them suitable for larger or more demanding jobs, such as cleaning medium-to-large patios, decking, and vehicles more frequently."
They add that the higher-numbered Karcher pressure washers are fundamentally more powerful and are built for more demanding applications.
Thank you for using Q&A.
I dont know whether this helps, but we have a very large garden and would not be able to use the machine without an extension lead. I am currently still using a very old K3 - at least 20 years old - and have always used an outdoor wind-up extension wheel with it, without any problems.

Hi Fran,
Using a cable extension with the Karcher K 4 Classic Home Pressure Washer - 1800W is not recommended. Pressure washers draw a high current when pressurizing, which can cause power trips if an extension lead is used.

Hello There.
After checking with our supplier, they have advised for Karcher K 4 Classic Home Pressure Washer - 1800W:

Hello Steve.
Karcher K 4 Classic Home Pressure Washer - 1800W:
The pressure washer is generally effective for cleaning grime from car bodies. It features a 130 bar max pressure and a 420 litres per hour flow rate, which are suitable for tackling stubborn dirt and grime.
However, the effectiveness can depend on the type and amount of grime, as well as the attachments used. For best results, using a foam nozzle and car shampoo can help loosen dirt before rinsing it off with the pressure washer.
Thank you for using Q&A.
Hi Scorpio,
We can confirm that water up to the temperature of 40°C can be run through the K4 range of machine.
Thanks for using Q&A.
Hi Jode,
The Karcher K 4 Classic Home Pressure Washer - 1800W does not hold water internally; it requires a constant water supply. When using this pressure washer, you’ll need to connect it to an external water source, such as a garden hose.
Thank you for using Q&A
