In this post I will review the Karcher portable cleaner dog wash, or as Karcher calls it the Karcher OC3 Mobile Outdoor Cleaner. This is great for cleaning off your muddy shoes after walks, but as it’s gentle I love using it on my dog to wash him down after his muddy dog walks.

The winter is coming rapidly and as much as I love wrapping up in warm coats, woolly hats, and coming home for hot drinks. It also means MUD. Lots and lots of mud, and being a dog owner that mud isn’t just over me and the kids, it is all over the dog too.

This was Gus last winter when he was a puppy, nothing has changed!!

Do you have a dog, and love getting out for dog walks. However the downside of having a dog means you have to be out dog walking in all weathers. Take a look at our grooming routine, and how I cope with muddy dog walks.

It feels like a constant battle to keep the house clean. With kids and a dog, it’s one that I can never keep on top of. So when Karcher offered me the chance to try out their Karcher Portable Cleaner, I knew this would be a great help for me.

What can you use the Karcher Portable Cleaner Dog Wash for? 

  • Cleaning off your dog after your dog walk 
  • Cleaning muddy boots and wellies 
  • Cleaning off muddy bikes 
  • Cleaning off muddy pushchair wheels before coming into the house 

Giving garden items a blast off before packing away 

Karcher OC 3 Portable CleanerSize 

 

The Karcher pressure washer is super compact, measuring 277 x 234 x 201mm it is not even the size of an A4 piece of paper. This is perfect to store in the boot of the car, ready to use after your walk. You could also place it in a garage/side path to use when you return for a dog walk, or out in the mud with the pushchair. 

Don’t think that because it is small in size that it won’t be able to perform well. It has a 4 litre water tank which holds plenty of water, enough to wash the dog’s legs, his underbelly, and our 5 boots off well.

If you are having to carry the Karcher Portable Cleaner around, you are going to want it to be light enough to carry. It’s around 2.2kg so super lightweight and even once filled with water you still can carry this easily. 

The carry handles take a little to get used to, as they lift and lock into position in certain ways. This makes sure the water tank stays locked in place when in the boot of the car. 

Pressure Quality 

It comes with a 5 bar pressure, which if you are like me and that means nothing to you! However don’t worry the pressure isn’t as strong as the ones you would clean the patio with, and blast off dirt!! It has enough pressure in it to be able to gently remove the mud from shoes, and the dog’s legs. 

Please note this is not high pressure, the Karcher Portable Cleaner is gentle on your dog’s legs and is not strong enough to hurt them. 

Performance 

 

The Karcher Portable Cleaner cleaned up the dog’s legs really well, here are a couple of pictures of before the dog walk, and after washing. It works great at getting off the mud and grass and really does make my job easier.

Then I used it on our boots after our walk, and I was very impressed with this. Nice to be able to pop the boots back in the car pretty clean.

Getting The Dog Use To It

You may find that your dog is a little unsure of the Karch

 

er pressure washer, it does make a rumbling noise and sprays out water onto them. Which may surprise them at first! So make sure you make it a positive experience, especially the very first few times. Have some tasty treats to hand to offer. I would suggest you don’t even turn the pressure washer on at first, introduce it to the dog at home and just offer some treats for the dog going near the pressure washer.

 

Once they’re happy to go near it, turn it on and offer treats to them. Once they are happy with this stage, then you can progress on washing them. Do offer treats with this as well, and each time you wash them they will be happy as they are getting some tasty treats at the same time!

Charging The Karcher OC3 Battery 

 

The Karcher portable pressure washer states that it has a run time of 15 minutes, so you can easily use it a few times before having to recharge it again.  The light at the front will start flashing when the battery is running now. Recharging is easy by plugging the charger into the front and taking around 3 hours to charge.

Refilling 

This is easily done by an opening on the top of the Karcher Portable Cleaner, although I did find it a little tricky to re-close the rubber seal lid. There is a certain knack to it, but I am sure I will get the hang of it with some practice! Once this is closed properly I haven’t found the tank to leak in any way at all. 

 

Accessories 

It comes with a 2.8mtr spiral hose, which is perfect for moving around your dog, or various people. You can use purchase various accessories to go with the pressure washer. Including a pet accessory box that can be attached underneath the pressure washer, including an additional conical jet nozzle, microfi

 

ber towel, and pet brush to brush out stubborn dirt. There is more accessories, for bikes, and different types of brushes. 

I like the fact that the hose can be tucked away in the bottom when storing it. 

Overall Thoughts On The Karcher Dog Wash 

Overall I am really pleased with the Karcher Portable Cleaner, I have been using this on every muddy dog walk. Not only have I been using it on the dog, but I have also been using them on my muddy boots and wellies. They were great for this, and nice to not get all the mud in the car all the time too. 

People have already spotted me using it in the country park after our dog walks! He shouted across the car park,

You need to hire that out to all the dog walkers, what a great idea and something I need with my dog who loves going in every river and muddy puddle! 

However I do think it is worth it, and if you are using it regularly you will love it as it will save you so much time and mess of cleaning the car, and house after your daily dog walk!

  1. This looks like such a great product. I could do with one myself at the kids always seem to get their shoes dirty before we get into the car to come home. I supposed that’s kids for you.

    • Yes luckily they have improved that path now, so not quite as much mud on that walk…however he still finds more mud anywhere else he can!!

  2. I love that you can use it on your dog, what a clever idea! I will have to tell my brother about this as he has a dog he walks on the fields near his house x

  3. My hubby loves our Karcher pressure washer. If I told him they did a portable one I know he would be off to the shop straight away – boys and their toys

    Your dog is a total sport. Lots of mud at this time of year so not a bad idea at all.

    Oh I totally need this for our dog! He is white and attracts dirt, I could so use this in my life!

    We have a Karcher, but it isn’t portable. I want this too especially since we have a dog and a child, not to mention we live by the sea. Can you imagine what that means? Too much sand and mud. This would be perfect for us!

    THIS IS AMAZING! What a genius little thing. This would be super useful to hose down the pram and trike wheels – I hate having to put the dirty wheels back into the car. Oooh, I’m so tempted by this.

    • Perfect for that isn’t it, used to drive me potty putting muddy wheels in the car and when you fold it up it goes over the seats/basket!

  8. This is perfect for the muddy months ahead….I love that you can use this on your dog as well as on muddy boots!

  9. We’ve been after a pressure washer for some time now and this looks ideal! Especially with how muddy our dog gets as well!

    Fab post! If I still had my pup I’d be investing in one of these for sure – unfortunately living in London and not having our dog means we don’t often get muddy enough (oh to be in the countryside!) xx

    • Ah that’s a shame, during the winter I am usually covered in mud so perfect for us. However I would love to be able to dress up smartly each day and not have to worry about the mud too!

  11. What a handy product for the muddy months – the amount of times the car or house has been covered in mud from wellies. This would save all the mess!

    • Super handy is’t it, I am going to blast everyone off before step foot anywhere near the house/car now!!
