Sir, for me ~ it wasn't even reasonable. It's like a water toy gun. But again, everyone has a differet opinion and experience ~ it just didn't fulfill my expectations. But for the price it wasn't that bad, its just good enough for minor cleaning & washing. There are options aswell, chinese options ~ but haven't tested them. You should test them all, before purchasing @ local shop (if allowed / possible). Or get a return time for the product.
Here's the best suggestion, get a normal conventional pressure washer. Opt for hyundai, but go for "INDUCTION MOTOR" pressure washer ~ compact, robust, efficient and it's not as noisy as a conventional pressure washer. We have sold alot of em, so I trust hyundai.
But, if you wanna clean ( minor cleaning ) yr car on the go and quickly ~ get a waterless cleaner, bullsone 2 in 1 waterless cleaner or you can opt for the pakwheels one. Haven't tested the pakwheels one, can't say anything about. The bullsone waterless cleaner does its job. We sold a quite alot em too, now I think it's called bullsone waterless car shampoo ( repackaged ).
If you still want a cordless pressure washer, which fulfills your requirements. Why not try a international brand ? I was able to find this, but I wouldn't recommend it ~ the price is completely unreasonable. There might be other imported options = local market/ lot importers. This particular site, I myself have placed orders ~ but I would recommend visiting their shop if your in peshawar. I can't guarantee a perfect exp from their site, but I received the exact items ~ I was shown. Always recheck reviews of all sites on all various places, Google profile, Facebook, Instagram and others.
