What Customers Are Saying
The portable pressure washer offers mixed performance. Many found it easy to use and convenient for small cleaning tasks, appreciating the quick battery charging and indoor use. However, several customers reported issues with low pressure, short battery life, and problems with the trigger and soap dispenser, limiting its effectiveness for larger jobs. While suitable for basic cleaning, the overall consensus is that the product's performance does not justify the price for heavy-duty use.

Would Not RecommendI was extremely disappointed with this battery powered power washer. Obviously, I wasn't expecting it to be as powerful as a gas powered pressure washer, but this has less pressure than putting a regular hose-end sprayer on your garden hose. Don't waste your money

The car wash gun
Would RecommendI really like this item as it works well. The motor power is really strong for cleaning my car. It will save me money not going to car wash service anymore

Wash n Go
Would RecommendWorks well for our need. the 40V battery worked long enough to get the vehicle washed well. The power was sufficient for getting the basic car washed (and dogs too) It is not for taking paint off or for sanding, so I got it for the right purpose. We used the soap attachment once and it worked well too. If we needed to go bigger, an air compressor would likely be needed. it is working well for the couple of months we have had it. Storing for the winter, unless we want to coat someone else's car...

Kobalt 600-PSI Rubber Pressure Washer Spray Gun Ki
Would Not RecommendAdequate pressure washer for light duty cleaning. Not very powerful as a pressure washer, but it is more powerful than a hose & nozzle. Okay for washing the car and light dirt on garden furniture but if you're looking for a real pressure washing experience you'll want to use a gas powered washer. I got this as a potential replacement for my gas powered pressure washer. I knew it wouldn't be as powerful but I was hopeful that 600psi would be enough for normal deck railing and even washing bird ...

Small jobs only!
Would Not RecommendI have a concrete deck that is just under 400 sq ft. The battery on a full charge died after about 150sq ft of work done. I am sitting here waiting for the batterybto charge so I can get my project halfway done. The trigger requires more pressure that most firearms I have ever used and of you are using the resivour attachment, I don’t know if mine is defective or not but the water keeps struggling to come out. When attached to a hose it works fine escept for the trigger issues. The pressure...

Impressed, but......
I am very pleased with the performance of this battery operated 40 volt handheld power washer. It greatly outperforms the one by Worx; however, the trigger mechanism needs to be improved. It hurts your finger after using for a bit and is difficult to keep engaged while using. Don't know where all these other reviews are coming from for other products, but they need to be removed for a better overall rating of this product.

A little disappointing
Would RecommendAfter purchasing this pressure spray gun to do light cleaning around the home I realized 600 PSI is not enough pressure. I am on my 2nd one. I returned the first because as you are cleaning it shuts down. This happens often while cleaning. I called customer service an they can't give me an answer as to what's wrong. Both have done this. It can't be overheating because sometimes you are just getting started. I am not impressed at all. And will be returning it.

Good power, poor operation
Would Not RecommendWhile this unit has plenty of power, it is very hard to use. The trigger requires tremendous amount of strength to keep it operating. So while moving the unit around to wash a wall or car the sprayer will stop constantly.

no bueno
Would Not RecommendI bought this to do odd light cleaning jobs around the house. The bad thing is that the fully charged battery hardly lasts 20 minutes. During which time it has no more pressure than putting your finger on the end of a water hose. Needless to say i couldn't wash my car with it. Just half of it. Really fast. Then i went back to using the hose to finish. It's close to being a scam. I returned it.

Handy to have
Would RecommendI have used it to wash the car, clean the lawn mower and clean the shower. Nowhere near as powerful as a gas model but it is more powerful than just a hose.
