What we thought

With an extremely muddy January walk still fresh in our minds (I didn’t know walking boots could attract that much mud!), when we were offered the chance to review the new Kärcher OC3 Portable Cleaner I jumped at the chance. Thankfully I’m happy to report that our days of dabbing ineffectively at muddy boots with a tissue are now over.

My boots after cleaning them

Now firstly, I need to make a confession: I am mildly obsessed with pressure washers. It’s a bit weird I know, but I used to have one of the large Kärcher pressure washers for cleaning my car, patio etc and I absolutely loved it, there’s something that’s just so satisfying about using them! Anyway, when the dinky little OC3 arrived I wasn’t sure how powerful it would be given it’s battery operated and I’m used to pretty heavy duty pressure washers.

A few days later we went camping and pitched in a muddy field, and later that afternoon we went on a walk around Delamere Forest, giving us the perfect opportunity to find out exactly what the OC3 is capable of.

The next day when we got home, we went for a local walk through Brook Wood and across a muddy field, we both used the Kärcher OC3 when we got back (see our video below) and it coped brilliantly.

Operation is really simple. The 4 litre tank is filled by lifting the large rubber cap on the top of the tank and then pressed back into place. The only minor gripe I have is with the big rubber stopper on the top is sometimes a bit of a faff to pop into place. To turn the unit on, there’s a large button on the font and a light comes on to show you it’s on. Grab the spray head, press the trigger and off you go.

Rather than tell you it cleaned our boots really well, it’s easier to just show you.

The verdict

The OC3 is a brilliant little device that’s extremely capable. Ideal for getting rid of mud when you’re out and about, making it perfect for campers, walkers and in particular dog owners. Whilst camping, we also found that the OC3 was brilliant for blasting bird poo off our canvas tent, so we’ll definitely be taking it with us every time we go camping and out walking.

With the Kärcher OC3 in the boot of my car I now positively welcome muddy boots!
