Sun Joe SPX6000C-XR iON 40V 5.0 Ah 1160 Max Psi Cordless Pressure Washer

First machine's auto-stop-start function didn't work. Amazon delivered a replacement unit and 2nd machine is working fine. Note the box that the 2nd machine came in had been opened and re-taped, and wax was applied at the joint of the handle/ sprayer. I had no issue with these as I saw it as a quality control step. So obviously Amazon/ the merchant has a special pile of stock that had gone through a test and passed and reserves it as replacement stock for customers who complained. How else could one explain every time a customer receives a 2nd unit, it works but the 1st unit is a hit-and-miss?Anyway, I use the Washer for washing the car. I require higher pressure for cleaning the alloy wheels and to work a foam cannon. It works fine for the former but not the latter. I tried it to do a bit of cleaning around the house such as the stains on concrete on the ground and window sills, it produces enough pressure for the job but I have to stick to the 15 degree and the pencil point nozzles which means it would take a very long time to clean a relatively small area.UPDATE AUGUST 2018... Still loves it. I learned from an online forum by replacing the orifice to my Foam Cannon 1.1mm or 1.25mm, it would work with low pressure washer. This cost me $8 and problem solved. I now get rich foam coming out of this washer! I did have the stop-start function fail on me but I just carry on using it. After 2-3 months, it miraculously kicks in and now the stop-start function works fine again.

12 days after I wrote this review, they came out with a new model which fixed the exact problems I was complaining about. DO NOT BUY THIS MODEL. Buy the new upgraded model here - https://www.amazon.com/dp/B07FFWB5CS.*****************************Let me start out by saying that I love this pressure washer. It is exactly what it claims to be - a stand alone unit that requires no external power or water. I have a 200' long dock with no power or water to it. I get a lot of large birds pooping at the end of the dock, but had no good way to clean it. This does the job flawlessly. So for performance and ease of use in situations like that, I would give it 5 stars. The adjustable power setting works great, and it has plenty of power for most normal cleaning tasks.My two big complaints are:1. The wheels. The unit comes with roller blade-type wheels which are great for smooth surfaces, like say a roller skating rink, but horrible for outdoor use, which is what everyone is going to use this for. So far I have used it on an asphalt parking lot and on my dock. It did poorly rolling across both. It is very hard to control, and the water sloshes all over the place so you end up spilling 25-50% of it. Huge miss by Sun Joe not to use an all terrain-type rubber wheel, like on a lawnmower, for this pressure washer. I have not tried rolling it across grass yet, but I don't think it will work at all. Hopefully they fix the wheels in the next version (and make a retrofit available for existing owners).2. The lid. The lid is a joke. It is highly necessary to keep the sloshing water from spilling out all over you and the pressure washer, but it fails miserably at this task. It does not lock or click down. It is just a loose fitting lid that really ends up serving no purpose. I'm not sure why it is there. Sun Joe really needs to improve this feature as well (and make a retrofit available to current owners).So in sum, if you need a pressure washer to clean areas that are not reachable by hose and electric cord, and don't want to invest in something much more expensive, like a gas pressure washer and external water tank, this is almost perfect. I used it again this morning to clean my dock and it works great. Sun Joe just needs to get to work fixing these two flaws and then they will have a five star product.

EDIT 07/27/2018:Thanks to a review made by Nicholas P., my unit now works just as it should. To fix the total stop system on my unit, I took a few steps. First, I removed the inlet port and found two filters both covered in some sort of white powder. I rinsed those off and reattached everything but hooked the unit up to a garden hose. I turned on the water but left the unit off with the trigger pulled to try and wash out any remaining substance, probably from manufacturing. Afterwards, I powered the unit on, let the water flow for a minute and released the trigger. The total stop system finally kicked in and now I'm satisfied with spending the amount that I did.Original:It is ok for the most part. It will clean lighter and shorter tasks as it is a battery-operated unit. Can't expect much or even compare to current cheaper electric pressure washers. I bought this to wash my car as I live in an apartment that does not allow the use of a hose to spigot kind of wash. Out of the box, the total stop system didn't work. I did have the trigger pulled to allow for water and air to flow out before powering it on.For the price, I cannot recommend buying this product. If you need a system that will clean light duty and short-timed tasks, a cheaper option is the worx hydroshot with a 5 gallon bucket. One-third of the price and just as effective. The hydroshot seems to be equivalent in pressure with the 40 degree nozzles and the sun joe at the lowest setting. The concept is wonderful but the product is sub-par.

I bought this pressure washer since I have another Snow Joe product and wanted more ways to use the batteries. The idea is great and it works pretty well with just water, mine had no leaks, BUT the TSS (Total Stop System) is hit or miss. Mine was a miss, and it doesn't automatically shut off, whether with the bucket or hose attachment. With this being a battery operated unit, that's pretty important. If I received one that worked I might be able to properly evaluate it, and even be happy with it. The included detergent bottle is far from a foam gun, so keep that in mind if that's what you're looking for.
