Bought this to clean the dog after muddy walks. cleaned all the mud off him perfectly. then I cleaned my wellies. After I got home cleaned the bikes and the car then the patio furniture. Best tool I have bought in ages. I filled it with hot water from the tap put in back of car under a towel and after 1.5 hours walking the dog it was still pleasantly warm. Long charging time 3 hours, No car adaptor and the water reservoir cap is very fiddly to close are the only down sides I have found so far. The pressure is adequate to power the dirt away without hurting the dog or damaging delicate components on bikes etc. If you need have more than one dog or you have a large dog I would recommend you take an additional 5 litres of water with you as I just managed to clean my ...

The accessories look interesting but in my opinion are a little expensive for what they are. In summary a very good machine with multiple uses that has good build quality.

This has been awesome. The only downside is the water tank - the standard runs out very very quickly as it is tiny however with the addition of the tube bought separately and a separately sourced water butt it is a game changer. The pump itself works amazingly and the battery lasts for 4 days worth of washes (I’m a dog walker) so has earned its stars!

I bought the washer in November 2019 and it has worked great until April 2022 when suddenly it would no longer charge up with either the mains lead or the car battery lead so is no longer functional. This is a great shame as I have previously recommended the washer to many people who have seen me using it by my car to clean my boots and my dog's paws after walks etc. The cleaner is quite expensive and I expected a Karcher product to be more reliable and not fail after only 2.5 years of use. I have used it only approx twice a week in that period so it has not been 'over-worked'.

We're on our third OC3 in the last couple of years. The motor on the first failed after a year or so, but we had left it on charge for long periods so likely our fault. The second failed after a few months and we only ever charged it on a timer, to avoid the same issue. Karcher refused to replace it, so we were left without it for a few weeks while they repaired it. We've now bought a third, expecting similarly poor reliability and customer service. They're great little units, and worth having two, with the 2-year warranty, to ensure at least 1 is working!
Why did I wait so long to get one? I got this with the 'bike clean' accessories and I really wish i had got one sooner, the beginning of the winter biking season would have been clever! I can now wash the bike after every dirty use BEFORE putting it in the van, then not only do I wash the mud off at the event rather than all over my drive, i also don't have to clean the van out of mud when I get home!The brush attachment is simple and easy to attach, just click and turn and then water comes through the brush as you wipe, perfect for getting the worst of the mud off, especially good on tyres. If you clean the mud off straight away, you really don't need cleaner (although you get cleaner and a spray head in the pack too). of course you need to fill it up with water ...

If you clean the mud off straight away, you really don't need cleaner (although you get cleaner and a spray head in the pack too). of course you need to fill it up with water before you leave home, and the tank is not that big so use sparingly or take some extra bottles to top up with. I used 2 tanks worth to do the whole bike. I even have started using it at home as its so easy to transport around rather than dragging the hose from the other side of the house.The clever bike accessories box holds all the bits and it just clicks on to the cleaner making a neat box and the hose sits inside nicely when you are not using it. Simple and small enough to leave in the car or van for any muddy days out, cleaning wellies etc.its still winter...Get one!.
Bought this for muddy mountain bikes and for this it is great. The pressure is perfect for getting off wet mud and cleans the bike well, without causing damage to bearings etc. It charges quick at home and the battary last long enough to thoroughly clean one bike or give a good clean to two possibly three.I have two issues however, the first is minor but you have to be carefull puting the water lid on as it is flimsy and easy to get not quite on with water spilling out as a result.The second issue is that the water tank is two small. It should be a minimum of 6 litres which would clean one bike thoroughly. You will definitely need to carry more water which is a bit of a pain.Overall though im pleased as it does the job, is easy to use and is reasonable value ...

I bought this 3 days ago, it is absolutely useless and the worst £110 I have ever spent! I have followed the instructions and charged the battery up twice and checked the filter .The low pressure washer gives me 1 minute of decent use before I get a trickle of water coming out of the nozzle. I leave the washer to re power a minute and then I get about 2 seconds of low pressure and then a trickle of water. So if you have a 2 legged dog or a monocycle it may be of use? But if your dog has four legs to clean or you have a bike with two wheels forget it . So disappointing, I'm taking it back.
Really impressed with this product. Easily clean my bike, boots, boat,metal detector, clothing etc. Pressure is just about right for a low pressure portable device. Small, light , well made with very useful handle makes it so reliable during each trip. With an extra water container and additional suction hose I can easily use it as portable shower as well. Well done Karcher.
I purchased this item a month ago, and it’s a really useful item to have around the house especially when your cleaning your cycles and around the shower room, this week I’m taking it to the cemetery to clean the gravestone at the weekend, should be very useful there.The battery life is good, and the water capacity is enough for quick uses. It’s not too powerful to use on cycles and pets.I recommend it as a general household item.
I've used the OC3 several times per week for the last two months to clean my bike after each road ride. I chose this product over other battery operated pressure washers because of the speed with which it could be set up for use as the hose and sprayer is permanently attached. I also really liked the lower pressure and coiled hose. The 4 litre water reservoir is plenty enough to quickly rinse the bike of mud spatters and road salt. For a road bike (which is not generally covered in thickmud), this washer is perfect! Fast, easy to set up for use and perfect pressure for gentle cleaning.
