Great upgrade from old Karcher K2
Bought a few weeks ago to replace my old K2. Great upgrade also came with the T5 patio attachment.

Compact but powerful for car and garden jobs
Bought this to clean rhe patio and paths, using the included patio tool. Instantly clean with minimal water and no mess. Then used if for the car - nice and quick results. And everything then stores away easily as the unit is so compact.

Brought this model for the bigger wattage also the slab washer that comes with it it’s outstanding bit of kit only downside is there’s nowhere to wind the power cables

Great jet wash
This was a replacement for the previous Karcher we had for many years. Great jet wash. So easy to use and cleated the flags so quickly. The base is light and on wheels so really easy to move round. Not cheap but wanted the more powerful one and was in the sale with a good amount off. Also, got Nectar points so a bonus.

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.
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 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.

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
