moving up from a 2700psi/2.3GPM machine this pressure washer has so much power, i was very impressed and slightly intimidated upon initial use :). the unit is pretty heavy and well built but easy enough to move around with the large wheels once assembled.
i did have an issue after unboxing whereas the cart frame was slightly dented. this was clearly a delivery issue and i reached out to Vevor Support and they were very responsive and resolved my concerns within a few days.
i would highly recommend purchasing this unit if in the market for a 4GPM upgrade or replacement. i did a ton of research on various brands and could not find anything close to these specs at the same price point. even used (marketplace) models were more expensive so this purchase was a no brainer.
the included 50ft hose is well made but not long enough for my needs so i upgraded to a 100ft hose of the same quality/specs and the machine didn't suffer any degradation in performance. it ran my 18.5 surface cleaner with so much power i will need to dial the psi back some.
one thing to note is the unit did not come with engine oil so you'll need to purchase a bottle to get started. the pump did come prefilled with oil.
i use this pressure washer around the house and i highly recommend adding an unloader valve, pressure gauge and optionally a hose reel (see pictures). it makes using any pressure washer so much easier and stress free.
