What to look in a Good pressure washer?

In a good or a quality pressure washer not only PSI matter, you have to look at each and every aspect before choosing a good pressure washer for you.

Usually, Brushless induction motor is better than universal type motor.


Like motor in electric,  Engine placed in a gas pressure washer that is run by gasoline, the engine is heavy compared to a motor that is the reason gas pressure washer delivers higher pressure compared to the electric pressure washer. Always look for heavier engines in a gas pressure washer.


The hose is another important part of a pressure washer or power washer and it should be long and flexible. 

Avoid the pressure washer that provides the shortest hose length. The length must be approx 20 to 25 ft long so you can move all around your car.

It should be a more flexible not stiff, flexible hose easily coiled up and stored after every use.


According to the user perspective, the pressure washer must be portable, It should be compatible with long tires so you don’t have to lift it after every use. 

More features require more money if your pocket is tight then you can go with the best small electric pressure washer.
