Karcher K 3.540 X-Series 1800-PSI 1.5-GPM Electric Pressure Washer Review

Karcher K 3.540

The Karcher K 3.540 X-Series Electric Pressure Washer was released in 2011 and is one of Karcher’s most popular machines. This is a mid range model from their highly acclaimed K3 series which is renowned for its blend of high cleaning performance and compact design. This pressure washer under review utilizes an induction motor which is water-cooled to deliver the level of durability you’d expect from a more higher-end machine.

Most consumers are satisfied with the K 3.540 with praise mostly given to its construction and performance. However, as always they’ll be negatives we need to pick up on. These will be discussed later on.

Features of the Karcher K 3.540 X-Series Electric Pressure Washer

• 1.5 GPM N-Cor pump
• Water cooled induction motor

Quick Setup

The quick connect feature makes setting up the K 3.540 a breeze. Just slot a garden hose into the adapter and it’s connected up to your water supply in a matter of seconds.

High Performance

Mid-range pressure washers typically don't have very durable motors. However, the K.3540 sets a new standard with its water-cooled induction motor which has a clever way of circulating cool water around the motor to keep down the temperature to enhance the lifespan and performance of the motor.

The machine delivers a PSI of 1800 at a rate of 1.5 GPM from the N-Cor pump. This is a very good amount of power to tackle smaller jobs like cleaning the car, the patio or your garden decking.

Accessories

In addition to the standard trigger gun, the machine comes with two different spray wands so you can get effective performance on different surfaces. The Vario Power Spray wand lets you the easily adjust the level of water pressure on the handle which makes it suited for tasks which require less pressure such as car cleaning. For those harder cleaning tasks, the DirtBlaster Spray wand gives you significantly more pressure so you can clean away stubborn dirt.

Detergent Tank

Onboard the machine is a detergent tank which allows you to easily apply detergent to your cleaning to get rid of tougher stains which water alone can’t remove. Using this feature is a 3-step process which just involves filling the tank with the detergent, connecting up the VPS spray wand and ensuring that you’ve set it to the lowest pressure before begging to spray it on the surface area. A flow dial is located on the machine which allows you to adjust the amount of detergent you wish to use so you won’t use up more than necessary.

Pros and Cons of the Karcher K 3.540 X-Series Electric Pressure Washer 

Pros

The Karcher K 3.540 is lightweight, reliable and easy to move. The water cooled motor system is a big advantage as far as long term reliability is concerned. Setup is a piece of cake thanks to the quick connecting system.

Cons

Although the main components of the unit are high quality, the same can’t be said for the accessories. However, on the plus side they don’t cost much to replace if in the event they do break.

Final Thoughts

For non-frequent, light-duty cleaning tasks, the Karcher K 3.540 X-Series Electric Pressure Washer is more than adequate. With its upright, lightweight design and large handle, manoeuvring the machine around is very easy plus its quiet operation makes it none jarring on the ears.

If you’re going to be cleaning large surface areas then we advocate getting a model with a higher GPM rating, but for those smaller areas this should suffice. In terms of value, we give this model a 5 star rating.
