The Karcher K3.540 has been an outstanding mid-level electric pressure washer. The product belongs to its X-series range. As compare to K5.540 the pressure washer has lesser features but have similar direct drive axial cam pump and induction motor. Both the models have VPS Wand and DirtBlaster Spray Wand and design wise both pressure washers are similar. Here in this pressure washer the detergent storage tank is also there in the place as of K5.540. Both the models contain a lot of similar features and similar issues as well. For a small and a medium level pressure washing tasks this product is highly suitable.
Ease Of Use: 5/5
With the help of quick connect to the hose, connections and wands are easier to use. In addition, the VPS wand allows you to spray with low pressure pattern. This feature facilitates while the detergent is applied and Dirt-blaster works with maximum pressure generated by K3.540. This is very simple to operate and there aren’t any complexities while operating it over. It can be moved from one place to another very easily. You get a startup and manual guide as to when you purchase this product; the guide entails operating, care and safety information. The product provides complete 1800 psi, which is great to attain in such a low price range.
Lightweight, awesome backup pressure washer, easy to use and maneuver over. The motor gets shut down by the off switch which help prolonging motor and pump life.
Spray wands and plastic tips tend to split over time. Vertical shape lets it to fall down often.
K3.540 is probably the quietest amongst all of the models by the company. When the induction motor is turned on, it vibrates to life with the push button. As to when the trigger is released on any wand, the motor gets shut down. You probably wouldn’t distinguish whether the motor is ‘on’ or shuts down.
The pressure washer delivers the similar 1800 psi at 1.5 GPM as promised during working. Such a power washing is sufficient for domestic and even commercial usages.
The product is suitable for any type of home tasks whether this is cleaning of car garage floor, patio, blasting dirt and washing the pool sides.
The product lacks in durability a bit as the product has vertical shape and fall very easily on uneven surfaces. While it fell over, usually the accessories are broken and this is a huge disadvantage!
Customer Support: 5/5
I would admire their customer support. I called their customer support to find out the difference between K3.540 and K5.540 models. The lady on the phone explained the differences very well. They provide very reliable pre-sales and post-sales customer supports.
Our Overall Rating: 4.7/5
All of the features of this product are really amazing. In such a low price, you get a very reliable product through which you can perform all of your household tasks with great ease. The Unbalanced upright shape is the only factor where this product lacks in.
