If you guys mind dirty nails and hands well don't watch the videos I am sorry but was through a grease session after which I did the unboxing:p
Also I may have mistaken the water adapter direction of inlet and also the pressure washer inlet outlet connectors so bear with me as I had not read the manual or had used the product then. I don't have any demo video but I can tell you got done with my car with a quickie wash in 15 mins including drying it down. Although not perfect it was meant to see if the thing worked properly and it did, the pleasure of using a pressure washer is leaps and bounds less frustrating and more satisfying then a garden hose, it's a thing I am looking towards to do on weekends. Took me 15 minutes to setup first because of light switches not working and having a rubber pipe that bent easily. I would need your help guys in finding me a hard pipe, I will post pictures of my predicament and then you guys could probably help me out. For now the video only covers unboxing, I am too camera shy to ask my wife to take a video while I wash the car also because I am in a rented property I don't want to act shoda in front of the neechay walay's servants or in front of the wife:p
Allah ka wasta hai bhaiyon nazar say bachanay k liyay video dekhnay k baad MashaAllah bol dijyayga, aapki bari meherbaani hogi this is more expensive then the watch I own
