    Been meaning to write this up... I bought the Yard Force YF4050 portable pressure washer a few months ago and have been using it to wash my Model S. It was about $250 on eBay. It has a 7 gallon bucket and has max 500psi. It's battery powered so you could literally bring this with you anywhere. No garden hose required (except for initial 1-time flushing to "prime" the system).

    I only fill it up a little more than half way (~4 gallons worth) which gives me plenty of water to wet down the whole car and get rid of all the bugs and bird poop. It comes with 3 heads of varying spray diameters and power. The white head (wide diameter, low pressure) is good for wetting down the car while the red head (narrow diameter, high pressure) is good for bugs and bird poop. You can add whatever soap you want directly to the bucket. I use an ounce of Optimum No Rinse plus an ounce of Optimum Instant Detailer in 4 gallons, wet the whole car, and wash/dry with however many microfiber towels are needed depending on the amount of dirt. The best part is being able to power wash in the privacy of your own garage (assuming you don't mind having a few gallons of water on the ground.

    That's a great find. When I travel long distance I'm always looking for self-car washes near my destinations (the trip to CA in July was a great examples). Now I can take my own with me:) Thanks for posting.

    Do you have to worry about etching through the clear coat/paint with the pressure?

    It's only 500psi so probably not.

    Update: I tried washing with several gallons of distilled water (under $1/gallon) and did almost no towel trying. After air-drying for an hour, the car had a truly spot free finish (unlike the "spot free rinses" at the self-serve power washes).

    And best of all, it fits in the frunk! (yes, dual motor frunk too!)

    Only slightly hijacking this thread, here's my set-up.

    In that my monster 240V /30A diesel-heated steam washer is in Alaska, and there's no way I'd buy one for down south, I took the advice of a commercial pilot friend who has to wash down his plane in remote sites. He picks up the $99 or so small washers available at Home Depot and Lowe's, saying that they last him a little more than a year and while in use, work quite well, so he considers it good value for the money - plus he can find room to pack them in his Turbo Thrush.

    So I picked up an "Eco Clean" at Lowe's for about that much. Claims 1600psi. I have used it twice inside with the garage door open just enough to permit drainage. The water here is quite hard but we have only the domestic hot water run through a softener. So I attach the washer's intake hose to the drain cock of the water heater. One also can affix a hose into a suitable utility sink's faucet, if properly threaded, but I do the former for two reasons. First, the heater is in the garage and at a nice convenient (elevated) height; second, water flowing out of the bottom of the heater is at a lower T than what is drawn off for domestic hot water use. Even so, I have remembered to turn the heater to dead-low 6-12 hours beforehand, as one does not want to use HOT water for washing.

    In any case, the water has been tepid both times and just right for the car. The softener has done its job and I have had no spotting afterwards. Comes with a 0º nozzle (do not use on a vehicle) and the white 15º head; entire unit is easy to carry and manipulate as needed. The pressure washer model does have, however, a worse-than-useless soap dispenser: it replaces the high-P wand and so water flows out and through the soap at hi-V/low-P so buckets more detergent gets wasted than necessary. So for the second wash I did a good rinse-down and then applied detergent with two or three micro-fiber cloths.
    Happy with the results; can recommend it as a reasonable alternative to the OP's unit. There are times when that self-contained water set-up of the OP comes in handy; I prefer the flexibility my machine has.

    Thanks! I just ordered from pressurewashersdirect, this is why I browse these forums :) This is great for my vinyl wrap too because it is max 500 psi, enough to get the dirt off without damaging the wrap (or the fragile paint if you dont wrap)
    Yard Force YF4050PB 500 PSI Cordless - Cold Water Lithium-Ion Pressure Washer

    I also got these microfiber sponge/cloth mitts and $10 spray pump that attaches to a soda bottle, so I can mix 2 parts distilled water 1 part isopropyl alcohol and spray that around the car after getting it wet with the low pressure setting, wipe with the mitts and then use medium pressure to wash clean (that way i wont have to use soap in the pressure washer, just distilled water). Maybe once in awhile I will use the Meguiar ultimate cleaners that are safe for wrap too.

    Also Hope's Perfect Glass cleaner is supposed to be the best for windows but Amazon sellers are way overpriced , someone said to check other stores like Bed Bath & Beyond (or for online the cheapest was DTEPs, I got a 32oz spray bottle and 2 2liter refills)

    Just to confirm: this is distilled H2O only, with no cleaning agent added?

    Distilled plus Optimum No Rinse. In retrospect there was still some water spotting which I noticed the next day so next time I'd still make a good effort to towel dry the car rather than air dry.

    Is the Yard Force as loud as typical plug-in electric washers? I still have an old Snap-On electric pressure washer from Costco (maybe seven years old at this point, amazing it's still actually working although I also barely use it anymore) which I've used in conjunction with a CR Spotless, but it's sort of cumbersome with the need to change filter media.

    Being able to dump a few gallons of distilled water into the tank and then forced-air dry afterwords would be ideal, but if it's noisy it becomes a concern with the neighbors.

    It's not too loud. No worse than the the tire inflator or garage door opener.

    How many minutes of sustained spraying does 4 gallons allow? How long does the battery last? I'm actually starting to seriously consider this.

    Hmmm. Good question. Will time it next time I wash the car. My guess is 5 minutes or so. Battery is good for 20 minutes continuous I think.

    I am getting a full xpel wrap. I am afraid of damaging to the wrap. I found a portable pressure washer that generate max 130 psi. Here is the link of a youtube video Drought-friendly, in-garage portable pressure washer, Yard Force YF4050 - Page 2

    The Yard Force generate 500 psi. Commasign and those that already have Yard Force and has a wrap would you still consider Yard Force with 500 psi or would you prefer the 130 psi above?
    I am trying to decide which to buy. I plan on doing the no rinse technique described by commasign.

    The YardForce come with 3 tips (red, yellow, and white). With the white tip on, it's as gentle as a spray bottle. The red tip is good for blasting away bugs and bird poop. I use it on the Xpel wrap and haven't had any issues. Remember the Xpel is designed to withstand rocks flying at the car at 80mph.

    @commasign. So the yellow tip will give the pressure between the white and red and a wide spray like those you see on youtube when they rinse of the soap? The white is like a mist, the red is concentrated nozzle to aim at a spot. and the yellow is a wide spray? Would this be a good discription? Thank you very much for responding.

    Interesting, I was just thinking a couple of days ago if such a pressure washer existed, but for a much different idea, for performing a cold-weather de-salting with windshield washer fluid, airplane "de-icing" style. It's so cold here right now that if I go and run through the indoor coin-op everything might be frozen sealed once I park outside.

    Once it thaws around here I was also interested in trying out the "touch free" distilled water final rinse... but:

    Hmm, I'd try distilled water without the agent. If it's only distilled water left on the car (which is probably the big challenge here) then it should evaporate entirely into thin air even in sunlight, no ?

    I'd also would be to use distilled water only (without the no-rinse washing solution mixed in) since I usually opt for the two-bucket wash during actual cleaning. Otherwise it's nice to rinse off bugs, bird droppings, and pollen during the spring months.

    I'd still follow-up a blower/dryer since the "clean" water that gets semi-trapped in crevices will eventually spill out, carrying any dirt/deposits within those hard-to-clean areas and leaving visible streaks. I've used an electric leaf blower, but warmed/filtered air would be more ideal (Metro SK-1 or Master Blaster).

    @commasign - how long does the battery take to charge?

    Exactly. Red = fine point high pressure. White = wide mist. Yellow = in between.

    - - - Updated - - -

    Yes, that should work. The ultimate spot free rinse.

    - - - Updated - - -

    Its pretty fast. 2 hours per the manual. But I've never had to use the full 20 minute max runtime since I'm trying to save water. ;)
