Mountain Washer Review
The 15 L Mountain Washer plugs into any vehicle with a 12V outlet. The spray gun comes with a 6m long hose and three attachments: brush, spray nozzle, and shower head.

Whether it's a winter mud-fest or summer dust-fest, the ride isn't really over until you wash your bike. That can be easier said than done if you're a high-rise dweller, stage race rider, or team mechanic on the road. If loading muddy bikes into the back of your van is making a mess you might want to check out the Mountain Washer. The kit which looks like a plug-in gas can on wheels is a portable mini power washer that lets you focus of the pleasures of bike washing while doing your part to conserve water. Brought to you by Kinetic Marketing and Distribution from the Pacific Northwest, the ‘made in China’ washer comes with a one year limited warranty and sells for $140 USD. MountainWasher

Mountain Washer review
The construction appears simple and solid.



The washer has a built-in high efficiency pump motor that plugs into a typical vehicle power outlet and is rated to last 15,000 cycles. On the back covered, the on/off switch appears to be fully sealed. It has a six meter long, half inch diameter black PVC hose with plastic quick-release couplings at each end. The 2.5 millimeter thick wall is fairly tough, and shouldn't pinch off or split over time like some garden hoses. The spray nozzle, brush, and shower head attachments snap and turn into the hand-held trigger unit. The grey and orange polyethylene plastic water tank appears to have a solid construction and there are three small locking wheels to roll it around.

Mountain Washer Review
Easy to fill, the compact size and portability was convenient. A full tank lasts about ten minutes at full blast.

The water filter can be removed and cleaned if you can get your hand through the hole.

Mlountain Washer Review
The quick release couplings worked well and are simple to replace. The full connector kit sells on the website for $15 USD.

Trim the hose back, press onto the receiver, and tighten the threaded cap to secure the hose.


Mounatain Washer Review
Pull the trigger and the pump kicks in, or flip the trigger forward to get continuous flow. Rinse with a wide spray or turn the nozzle for a higher pressure thin beam of water to flush dirt from tight spaces.

Function

The unit was easy to set up and both the hose and plug-in cord seemed a good length. We ran the washer continuously for multiple cycles without the vehicle motor running and had no battery problems. Every time you fill the tank, you’re supposed to turn it on and purge the air from the system. This was straight-forward enough and the washer ran fairly quiet, switching on and off as one pulls and releases the trigger. Flip the trigger forward to get continuous flow. The small nozzle performed well and can adjust from a higher pressure thin beam to a wide light spray. If your bike is really muddy or baked on you may need to be patient since the mountain washer just doesn’t have the flow to wash your bike quickly. The tank held more than enough water to wash one really muddy bike well, and 15 litres lasted about ten minutes at continuous full blast. Washing two muddy big bikes might be a stretch at seven and a half litres a bike. By contrast the garden hose takes about five minutes to wash the same bike, but uses an estimated 35-40 litres.

The long brush was pretty useless for bike washing and like the shower head it was soon stashed in the side mesh pocket for non-bike related uses of the mountain washer. The shower head might be good for washing muddy four legged ride buddies. A removable water filter is located inside the tank, but the three inch diameter opening is a bit small for extra large hands to reach it. The hose’s quick release coupling attached and detached easily, and it was good to see a variety of replacement parts available on the website. In the end my bike and shoes were clean, and I was happy.





Pinkbike's Take:
bigquotesIt's debatable if washing your bike is critical maintenance, but it's always a good time to bond with your bike and check for possible mechanical issues. For some folks the Mountain Washer could be considered a luxury item, but for those who really need something compact or portable this unit is a good solution for washing your bike. The hose was an adequate length and the sealing, pressure, and small spray head, all performed well. Although the washer tank and hose seem durable, I would not be too rough on the plastic connections and attachments. The need for a second water source to complete two bike washes make this product a bit impractical, but it made good use of 15 litres and certainly did conserve water. - Chris Johannes

 Why not if you have weak limbs and much moneyWink
I just got something like that: www.ebay.co.uk/itm/Portable-Pressure-Washer-Power-Pump-Car-Jet-Wash-Brush-Hose-Lance-Cleaner-8L-/380984810481?pt=LH_DefaultDomain_3&hash=item58b476dbf1

The good thing is that it does not need that horrible 12V stuff to work. So you can use it in your bedroom spraying massage oil and other fancy juices to your girlfriend and to your girlfriend's girlfriend.

 Nieeece!
I have been thinking the the exact same pump. Is it working well?
  • + 5
 Works super-good, I got 5 litre version and that's enough for 2 washes. Of course, I am not very pedantic neither.
You need to keep the pumping a few times to keep the pressure up but it is good for ur tricepsWink

 considering this is a chinese-made plastic water tank for 140 bucks, I would say Hillar's version is way more reasonable

 I have a sponge and a bucket and I add a dab of Blue Dawn.

 I have one. I can wash 2 bikes well enough to put in the back of the car. If you want the wheels washed though. Bring some extra water. It is only 8 litres.

 dish soap will dry out any rubber over time, you've been warned! i find just water and wiping down everything with some rags after works the best for me
  • + 1
 i wash my rides rarely as too much washing kills bbs and hubs and any other moving parts like shifters. BLUE DAWN was product of the month a few years ago on a few bike sites

 $15 pump sprayer for weeds will do the same thing and needs no 12v.
  • + 1
 really people...we are washing bicycles. Why would anyone introduce a motorized plastic power demanding machine, probably made in China? It will most likely crap out and that bucket with a simple sponge and ONE DAB of blue dawn will be the tool of choice. Easily cleaned unlike a problematic devise you now have to store, clean and generally take care of....more crap for the car port?

 i bought a 2 gallon chemical sprayer from the hardware store for $7. it cleans one bike from absolutely covered with mud to clean with water left over. you have to pump it by hand but it also cost $7 and not $140.

 Haha I checked the link, you're right! He did sort of go on to say the problem was with bikes that get washed a lot and ridden rarely.. I like the sound of this mobile pressure washer though

 so to cure depression we need to ride more, wash less and generally have a good time? I like it.

 Water kills pivots. Once I started to exclusively ride my hardtail on trails with water crossings , as well as stepped hosing my bike down, suddenly I never had a problem with my bearings.
  • + 1
 @Rubberelli Haha I cant tell if you are trying to be insightful or sarcastic. Wink

I have also heard that excessively washing your bike can cause problems. Just dont point pressurized water at anything that has a seal!
  • + 1
 Nope. I'm here to report water kills pivots. Doesn't matter if it's a water crossing or hosing it down. I say don't ever wash your bike unless you're selling it and get a hardtail for trails with water or lift it and walk through. Replacing bearings suck.
  • + 2
 @Rubberelli haha sorry, the way you worded what you were originally saying, sounded like you were trying to say that once you switched to a hard tail, you never had any more issues with linkage bearings Wink

 I've got one of these, it's really good for impromptu drive by spraying and wet t-shirt competitions. I always win.

 Perfect for those of us living in an apartment!

 Or for the van/ car. Trying to transport your bike in the winter (and sometimes summer over here) gets pretty messy.

 Exactly what I was thinking! I have to get my bike on the shower every time I need to give it a proper wash and end up doing a mess all over the bathroom...
  • + 4
 Use a large super-soaker gun ($5-$10 anywhere), and get the job done without the battery hassle. Then you still have the perfect weapon for wet t-shirt contests.

 What if I just got one of those backpacks for spraying weeds, filled it with bike wash and pumped it up?
  • + 1
 I have used one of deck/weed pump sprayers and it will get the job if you use a brush along with it. They don't have nearly as much water flow so it can take for-ev-er if mud is caked on. They work great for lighter duty action. These back pack washers hold more water, take less effort and will get even the dirtiest bike clean in under ten minutes

 Wally world sells a 15 gallon power sprayer that runs around 40 psi. It comes with and 8ft power cable and battery clamps. You could keep it in the bed of the truck and spray off at the trail head. Higher psi would be nice, but 1 gallon per minute is good for cleaning without killing bearings.

 interesting, no battery and less expensive! www.walmart.com/ip/Precision-15-Gallon-Spot-Sprayer/23010535

 I have one of these (bought from chain reaction in the UK) and it's pretty decent. Don't leave it in your car full of water in sub-zero temperatures though, the water froze and blew all the seals out. Easy fix though, thankfully.

 I have one since 2 years and it was one of best buys ever for my bike universe... I took a large model with 17 liters. Can wash 3-4 bikes and my motorcycle with ease and anywhere.. The pressure is just right so you can spray into hubs with no problem (checking hubs and BB regularly). Takes 2 min to clean all mud away.. Of course use some big brush or sponge with bi,e shampoo to clean the rough stuff... One trick makes it even better - use filtered water and the bike is clean and shiny without wiping it with a cloth... Really good stuff..

Look for the quality though, I had to re fit some seals as there was leakage at delivery due to moron working at assembly or final quality check. I opened all places with seal and two needed to be inserted properly. After that, all issues gone and all works fine since.

 You can find it in Europe under "aqua2go".. Another much more expensive but not worth the difference is "nomad"

 Bought the exact same washer maybe 4 years ago at Canadian Tire for around $50.00. I'm anal about cleaning my bike and thought this would be great, but it just wasn't working for me. Not enough tank capacity and water flow. Hard to describe, but just wasn't ideal. Stopped using it.
  • + 2
 Nice, I end up spending 10 bucks a week washing my bike after every ride, usually 2-3 times a week. My bike is an indoor bike so I have to clean it after every ride. I need to get one of these.

 Is there such a thing as a soap or a solvent I can use, spray on liberally with such a device, without contaminating brake pads?
I've always just used straight water for fear of contaminating brake pads, but I'd love to hear about a soap or solvent that leaves my brake pads functional.

Maybe I'm dreaming.
  • + 1
 any soap should be fine for your brake pads? All soap is made to brake down grease (aka lubricant) so if anything, it would only help.
Otherwise I have used dawn with water to get my bike completely covered in suds, and no problems!

 I have one of these (sold with a different brand / name here in Italy) as my wife required one since I moved all the bikes from the garage to a spare room in house. It works fine, the pump does have enough power to wash off dry mud... but after one year of use (less then fifteen times) it started to experience some leakage from the tank bottom valve attachment. It seems that one of the inner o-rings keeps failing and it's a bit annoying as now I have to plug a rubber cap to the valve attachment in order to avoid water to leak. Unfortunately I was not able to find any spare replacement... apart from that, as it costed less than 50$ it's being still worth the price.

 was looking where to buy this and CRC have a one called the Mobi V-15 which appears to be the exact same thing but blue rather than orange. Will be trying to pick one up before the start of my season

 It's just like a Moby jet wash I've had for years. If it's as good as that I would highly recommend it. Great for cleaning the bike and car and not too high pressures so it wouldn't blow all your grease out of your bearings.

 I have had an earlier version of this unit for several years, works well, has held up and can be disassembled and cleaned should the pump get clogged. Good unit!

 Use a cleaner that doesn't clear grease or lube and just stand back a bit. Better than adding abrasives to your grease.

 a power wash extracts grease and oil. Fail.
  • + 1
 @madmon lmao. A power wash? Extracts grease and oil? I don't know what machine you're talking about but a pressure washer just squirts water under pressure. The closer you are to whatever you're washing the more pressure the water stream is at when it hits said object. Yes, it's possible, if you're a moron, to force water into seals and to remove grease and oil with a pressure washer. But if you're not a moron, you'll do just fine.

 have an old towel to dry it off and/or put a tarp down in the back of the car, same as you would do for a bike thats dripping with mud. www.pinkbike.com/photo/9443411

 personally, by the time my rides are done any mud is dried on then you can just brush it off. i try not to ride trails in the soaking rain, but have a few times. in those cases i take both to the car wash. i never really think about that one on the east coast. normally tho, dust and dried on mud dont affect a tarp covered interior. water leaking down into the carpet or cushion is a different story.
