Customer Reviews for Karcher - eco!Booster Pressure Washer Nozzle: 1/4" Quick Connect, 50% More Cleaning Power for Cars, Fences & Patios
Posted by: TL25
Verified Purchase:Yes
Bring back the old version of Pump Guard, The threading on the attachment tube did not match properly with the power washer attachment and only engaged a few (if any) threads and when I tried dispensing to my power washer the contents sprayed on out on the ground.
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] I won't have an opportunity to try this out until next year when I attempt to get the power washer running again. I did get a power washer previously but it came defective so I'll need to work on it to get it in working order.

Reliable protection for your pressure washer pump
on December 10, 2025

[This review was collected as part of a promotion.] I used the Kärcher Pump Guard Can to protect my pressure washer and the product worked as expected. The liquid has a clean consistency and leaves no residue inside the pump. It flows well through the system and helps prevent corrosion during storage. The scent is mild and not irritating. The bottle is easy to handle and the built-in applicator makes the process simple. It is a good option if you want to keep your pressure washer in good condition for long periods.

It helps prevent corrosion and freezing, which keeps the equipment running smoothly. Overall, it’s a simple, effective product that offers great peace of mind.

[This review was collected as part of a promotion.] I use the Karcher pump guard can with my pressure washer as a lubricant and anti freeze. This is such a relief especially in the winter that your pressure washer is protected. Does the job right and is very safe

Defective can and poor instructions. Disappointed
on December 17, 2025
Posted by: brendanl10_7683
[This review was collected as part of a promotion.] I realize that winterizing is an important when it comes to pressure washers, and was really hoping that this would be as easy of a task as Karcher’s instructions would indicate: 1) Attach hose securely. 2) Depress button to dispense fluid. 3). Release button when fluid exits water outlet.
Unfortunately, I had a terrible time with this product. Here’s why:
First, when I was connecting the spray tube to my pressure washer, the gray plastic piece became disconnected from the hose and wouldn’t go back on. I was finally able to get it reconnected, but only in a way that made the connection less secure than it should have been.
Second, nowhere in the instructions for this product does it mention that you should only use it outdoors. It’s December and below 30 degrees here and I’ve got everything stored in my heated garage; I figured I’d use the product there. Well, it takes only a moment for the product to exit the water outlet. And when it exits, it does so with enough force to send it about 20 feet away. Across the garage, onto my stuff, and leaving a stain on my garage floor.
What a mess. Karcher makes awesome pressure washers, but Karcher Punp Guard is garbage.
