Hi all,

I live in an apartment. At least twice a month I like to take my cars to the local pay and spray car wash for a traditional bucket wash. ( the kind where you put quarters in and get 5 minutes with a pressure wand)

The problem is that when the weather is good everyone ends up there. I just dont feel right doing a bucket wash with people waiting, assuming i even get a bay at all.

after 2 weekends of frustration, I bought a cordless power cleaner. These things can draw from a bucket, and dont require a hose.

I chose the dewalt 20v because I have dewalt batteries. There are several brands, including Ryobi 40v (which is supposedly better)

let me start off by saying this is not a replacement for a pressure washer. The pressure is low, and the flow is even lower. However, it will clean and knock off loose dirt.

Cost:
150 for the dewalt is too much in my opinion. Ryobi has a 1200 PIS 1 GPM model for 200, and thats a significant upgrade. That said if you have the batteries...

Cleaning power:
it works, not as well as a hose fed pressure washer but it does work. If you need to bucket wash a car and dont have a hose. You can use this. It will take some extra time to get the soap off, but it will do the job.


Water usage:

A 5 gallon bucket is not going to do a pre-rinse and post rinse. I normally go through 12 gallons on a small sedan.


Battery life: In my experience a 5 amp hour pack is sufficient for a small car. I wouldnt try to wash a car with anything smaller.


X factor:

One way I like to use it, is to use rinseless wash for the water feed. The initial spray washes off the loose dirt, and I can go right into a normal Rinseless wash on paint that is already lubricated. This usually ends up using a 5 gallon bucket of feed water and 3 gallon bucket for the wash itself. The main downside is doing wheels etc needs more water for a proper wheel cleaning. Id use this as my in between step for a car not dirty enough to require the bucket, but still a little too dirty for a normal rinseless.

Lugging all the water out, and using it is a lot of extra work compared to a normal Rinsless wash. I dont do it often. The hose also likes to come out of the bucket and it looses its prime. Priming is a pain, and takes a good 10-20 seconds each time. The siphon hose also is not long enough to get around a car so you have to be strategic about where the bucket is placed.


Final thoughts:

Its an annoying imperfect solution to not having a hose for car washes. With that said, it does work. Its also a good portable solution.
 
I have the Ryobi version, though I don't use it for detailing, I share similar frustrations. However much water you think you need, you'll need at least 50% more. But if you live somewhere without a hose and get your car really dirty, this is an option. Not for mud caked cars, but it is good to blast off stuff that is too much for a rinseless wash. Not sure about the Dewalt, but the Ryobi is super sensitive to being run out of water. I smoked my first one after about 2 minutes of it not priming itself.

Honestly, I still prefer loading up everything and heading to the car wash, or doing a rinseless. But for when neither work, its nice to have. Also something I would use when taking my ATV places.
 
It's tough for apartment dwellers that don't have hose access. Think if I were in that situation I would do the following.
I'd go to the coin car wash and foam presoak the entire car with a good touchless and a battery powered pump sprayer such as IK pro foam 12. Then all you would need the car wash wand would be a rinse. You could even presoak before going into the wash bay if you timed it right.
Then immediately drive home and do a rinseless wash with an IK Multi Pro 12. Yes you would need two pump sprayers but you wouldn't need the bad 20 volt Dewalt tool.
 
Dewalt also makes a 60v 1000 psi version. Pricey tho.
The psi isn't the problem. It's the water. 5 gallons runs out fast!

Not sure what the problem is these days but back when I was a dweller, we had a car wash station and wow was it busy. Great place to chat with other car folks.

If I had to do it again and they didn't have water for car washing I'd get a 100ft zero g hose and a sink adapter.

I actually have a hose and a faucet adapter. The problem is getting the car somewhere the overspray isnt getting on someone elses car. I usually park further away to do my washes and use the hose to fill the buckets. Should be moving into a house early next year though.
 
Figure out what is the most convenient method that still gives good results and do that.

Take the hose nozzle off and just flood the area, it should keep overspray at minimum.
