I use this electric Sun Joe pressure washer to clean cement patio, wood decking, cars and truck and vinyl fencing. It does an absolute great decent job. No water leakage on washer, motor cuts off when releasing handle pressure, light weight, easy to move, and 5 nozzles for any type of job.. Had only previously experience using gas pressure washers. Now at 70 and with two hip replacements I found the back pressure on the handle wand on the gas pressure washer too much and gas pressure washer too loud and too heavy. The Sun Joe is just what I needed, and my wife as she used it to clean her car. Assembly was easy with easy to read and follow instructions.

All I can say is awesome, multiple tips, easy to assemble, easy to disassemble and store and with 2 separate bins for chemicals. This runs great and for the price can’t beat it

Can’t really rate the product as I haven’t had a chance to use it. It did come very quickly and everything was as described.

Worked for two years of very low use then broke. Unable to fix. Spend more money for something that will last.

Broke after two seasons, it won’t turn on anymore. It worked okay but definitely never felt like it had the cleaning power of a gas washer. If you got really close and went slow you could get most the grime but the time that took was sooo long.

Tried it today what a difference! The green mildew, ground in dirt all came off of the pavers and bricks. Couldn’t believe it! I have a lot more to go, pavers and sidewalks and walls, oh my!!
