Power Pressure Washer

Just received this PW, assembled it, put gas and oil in it, have not used it yet. Looks sturdy and built very well.

Incredible

Couldn’t be happier with the unit, previously had a 3100 psi and wanted the commercial grade of this unit of 4400.

A lot of pressure washer for the money

I just bought this pressure washer. I was planning on a smaller washer, but with the price and features I couldn't pass it up.

Great features

Everything in the box as advertised. Even the box came intact and sealed. Rarity these days. No missing parts or pieces.

New machine

Easy assembly, started first pull. Only complaint is it came with 16 oz of oil, capacity is 21. Hopefully it lasts
