Added a Total Stop System to a Sun Joe SPX-9006 / SPX-9004

[@GarageGeek]

It is worth mentioning for anyone who wants to do this to a pressure washer that motors experience an inrush current up to 20x greater than the rating. Current kills motors. Starting and stopping an electric motor that has not been designed for an intermittent type of duty cycle can cause premature death of the motor. Something that is done in industry is to install a time delay relay to the pressure switch so that during brief intermitted use of the trigger the unit will stay powered, if you let off the trigger for some period of time (saw 30 or 60 seconds or so), the machine will turn off. That solution is better for the motor because it stays running during those moments that you are quickly repositioning the sprayer wand, but also prevents the unit from being left powered unattended which is bad for the pump.

This is awesome. I just found your vid and wanna thank you for sharing it. I have the SunJoe SPX 9007 pro and I’m loving it but unfortunately this model does not have a total stop feature and would love to add a tss now I know that it could be done thanks to you. I would love to see how the electrical connections were made.

[@ChrisL-rh7io]

Thanks! I'm glad this is helping others. Another video was loaded recently for how to install it including the wiring. Let me know if you move forward yourself amd how it goes!

[@musicguitar]

Awesome job! I’m not that mechanically inclined. I bought a surge outlet that came with a remote control on/off. I plug the pressure washer to the outlet and leave the small key chain remote in my pocket and just press it when I need to use it. Kinda annoying but it works and I’m used to it now. Wish SunJoe would just add the damn auto off/on.

[@ChrisL-rh7io]

Good timing - I just posted a video of how it works. Hopefully it's detailed enough so anyone can do it!

[@musicguitar]

@@ChrisL-rh7io awesome! I’ll check it out.

Hey Chris great video tyty... this is exactly what I'm looking for for my Canpump Electrojet CR3000 it's 1500psi and 2.2Gpm 2Hp motor and 16amp 120V... anyway was just wondering if you remember where you purchased the switch? If you have a link or something that would be much appreciated.

[@ChrisL-rh7io]

@@dieseldan2003 This ultimately ended up not being a solution. There was always issues with every iteration and i wanted it perfect. I eventually gave up and bought a new pressure washer.

[@cebasmb8250]

Sweet setup man I'm looking to do my pressure washer the same but hard to find a pressure switch with 120 plug.....could you help me out here please where I could find the switch?

[@tommyt484]

Nice work.

[@joec8167]

Nice upgrade, would like to see the in detail video of how to install that switch. 👍🏽 and what orifice are you running on your nozzles. 3.5 or 4?

[@ChrisL-rh7io]

Thanks! I plan on doing a tutorial pretty soon so stay tuned. For orifice, I'm using a 4.0 👍

[@imbarath]

Hi, im planning to get a arblue 630, this model doesn't have the tss. Thr local shop saying the 630 model with the tss isn't available in my country. Im wondering would the modifications as yours would work on the ar 630 model cause it says it has a automatic pressure relieve system. I dont really know what that means.

[@ChrisL-rh7io]

I had trouble ultimately finding a pressure switch that worked with the sun joe setup. AR offers several models which have TSS so my best suggestion is to find one with it vs a retrofit as although I was close, I never found an end result I was 100% happy with

[@joekerschner1672]

Great Job, Can you add a LINK to buy the pressure switch?

[@ChrisL-rh7io]

Hey Joe. I posted an update on this as I ran into issues using a foam cannon. If you don't use one, I can purchase a switch below but if you do, I'm still on the search for a switch that fits those needs but to be honest, it's not looking promosing. www.toolbarn.com/karcher-8-712-262-0.html/

[@04guzman8]

What type of attachments are the ones you use where the water hose connects?

[@ChrisL-rh7io]

Hey there, all parts used are in my cart build video!

[@jp48506]

Chris, how did you fiqure out the issue from the pressure switch cycling in and out?

[@ChrisL-rh7io]

With this switch, I didn't have any cycling problems except when the foam cannon was being used. I'm still in the process of finding one that accommodates the increased foam cannon pressure. What you can do is turn the unloader dial back a little bit - if you're on the cusp of the pressure actuation psi, this should help but i don't recommend dialing it back too far.

[@joelmunoz2330]

Question on the CoxReel. I to own 50ft CoxReel. Did you use and coupler or elbow fitting when you install your Kobrajet hose to the reel? Can you provide a link too?

[@ChrisL-rh7io]

Nope, no elbow needed. I recommend removing the rubber sleeve. It'll make it a lot easier to attach it directly!

[@rafashapradipta9869]

Link switch..????

[@canoeshoe]

i would like to copy thissss =) =) =) thank you. Def update with a part's list if you can

[@Hot.Tamale714]

Unrelated but how did you get the QD with no clearance on the mosmatic xD

[@ChrisL-rh7io]

I'm using the Mosmatic coupler from OG but on a 29.132. There's still a gap, but it's small and you can't really see it in the video. I will say that the fit and finish is nice on the Mosmatic QDs, but they leak or don't fit well with MTM parts so if I had to do it again, I probably wouldn't have upgraded because I had to change out more pieces than I wanted to.

[@Hot.Tamale714]

@@ChrisL-rh7io oh wow did not know that. Thank you for the insight. Much appreciated :D

[@h.m.jjammag2782]

Hi Chris, where did you buy that pressure switch?

[@ChrisL-rh7io]

I got it here but I did have some shipping issues with them that took months to resolve. May want to look elsewhere etscompany.com/

[@joegehring69]

Do you have any problems with the foam canon

[@ChrisL-rh7io]

Yep, I've mentioned it in other comments and is why I haven't posted the DIY. My solution is to use a pressure switch with a higher rating than 580 but am currently in process of moving so haven't had the time to do all this as much as I'd like to.

[@joegehring69]

Cool how do you like the pressure washer I was looking to get the same one does it produce thick foam

[@ChrisL-rh7io]

@@joegehring69 Yep, it foams pretty well with my pf22. I wouldn't say it's worth the $400 original sticker price but for ~$200 when Amazon has a sale, it's an amazing deal. Not having total stop has been a headache. It's pretty inconvenient but is the only issue I have with this machine

The activation psi at 580 is still too low though and has issues when I'm using a foam cannon. I'm still looking into a solution.
