Parfait, facile d’utilisation. Fait parfaitement son travail.
Attention cependant à acheter le chargeur de 18V vendu à côté car non fournie

Ich habe ein Gerät „Gebraucht, sehr gut“ für gut 100€ gekauft. Ob dieses Gerät jemals benutzt wurde, ich habe keine Hinweise dafür gefunden. Alles sah unbenutzt und neu aus. Gekauft habe ich das Gerät für die Autoreinigung. Sowohl die Autositze als auch der Teppich sind tadellos sauber geworden. Da ich die 2 Akkus besitze war das Arbeiten kein Problem. Der kleine 2,5 Ah Akku schafft ca. 13 Minuten. Für das Reingingen der Sitze reicht es, der größere Akku wäre wohl die richtige Wahl für dieses Gerät.

Sono contento ,mi piace qualità ,Grazie mille.

The charging time is around 4 hours for about 15 to 20 mins worth of use
That is insane!
Using it is fairly easy until you need to change nozzles and then it’s fiddly
There are a few upsides:
It is very portable and it is very powerful
I’m disappointed in Karcher, their products are normally a 10/10 but this is leaving a lot to be desired

PROBLEM WITH TEH BATTERY WHICH IS THE ISSUE WITH MANY OF THESE DEVICES

Definitely comes very handy to have such a piece like that around the house, especially during the potty training period.
Besides the vacuum cleaner, it depends on what type of washing product it’s being used.
I found it very useful. The Karcher SE 3-18 arrived just in time. on the same day, I spilt a coffee in the car🙈
Apparently, the charging time is around 4 hours and can be used for 20 minutes ish.
I found it difficult to change the nozzles.
The carpets remain quiet wet.

Karcher make such great products I was a little disappointed to find that this while pretty decent has a couple of glaring flaws.
I’ve tested this on an old sofa that really needed a bit of a clean, the carpet and some stairs. I would have done a lot more but the biggest problem with this is the battery life. You just don’t get nearly long enough to get anything done properly. The battery that comes with it takes about 5 hours exactly to charge for just 16 minutes of work. I do believe it’s possible to buy extra but at the cost you’re paying originally I’d expect a lot more.
It comes with one packet of 100ml cleaner as well, which is good for a single use.
On the sofa, I just about managed to get 5 of the 6 cushions done but even then I felt rushed and didn’t have as long as I would have liked with each. I will say, we did get quite a bit of dirty water from it, which is exactly what you’d want showing that it works. However, I still feel that those same cushions will need one possibly even two more goes over, with that said, it’s an old sofa so I can’t put all the blame on the machine here.
When it comes to the carpet, it was easy to use and did a fairly decent job but again, not as good as I’d have liked and I feel once again that comes down to the time constraints due to the battery.
Now for the stairs, it did a great job here, I know this because I could only get half the staircase done and standing at the top I can see a big difference between them. Now just to wait 5 hours for a recharge and I can get the others done.
It’s hard to know truly what to think, the machine is very lightweight but has no hard tube so you do need to do a lot of bending over or on your knees but it’s easy to move around. It’s mostly made of some sort of plastic I believe. It’s also very simple to use with a single on/off switch and a button to squirt the water otherwise it just vacuums it up. You get quite a lot of dirty water but I do think the suction could also be stronger.
For around £240 I’m really sad to say I expected more, especially from Karcher who are usually excellent. It does the job but with such a short battery life it’s hard to finish the job in one go. Of course, there’s nothing stopping you from getting a bigger battery or an extra and in that case, I’d say it’s probably a lot more useful, but for this price I’d have hoped that would already be included.

The battery to operate this product is not included in this offer, currently being advertised at an additional £60 to £80 and also the battery charger is not included in this offer, with an additional cost of £35 to £50.
So you need to add a minimum of £85 to the advertised cost.

Karcher compact vacuum, looks like it could be a great product. However the one I received has an issue with spray device and does not spray any water out from new.
Battery charging time is 260mins, the charger is very slow for the 15 mins run time, however the battery gives a lot of data like how long left it has to run.
The unit it self it light weight and designed well with places to clip on attachments, to make for easy storage and travel.
The water vacuum side is good and has a power suction for quick water clean up.
Would be nice if they had a spray, brush and vac attachment with it but looks like you can buy one as an extra.
This idea would be ideal for quick spill clean up or a car freshen up, however you mush be well prepared with the battery as 15mins will soon go by.
I contacted customer service reference the item coming defective, however my only choice would be to return the product, as you cannot make contact to Karcher through Amazon. I did however get on the Karcher support quickly and easily even if they could not solve my issues.
Overall if you get a working vacuum, the battery is only good for quick clean, however is a very portable device.

Very easy to use, bought with 5ah battery and charger, so has a great run time, simple to load tanks with no sign of any leakage, cleans a variety of mess efficiently, ( follow instructions) works very well and easy to stow afterwards

Attention livré sans chargeur

The extractor works well but sad it doesn’t come with battery and charger. Since I’m in the USA and use the tool brand Milwaukee it made the most sense for me to buy Milwaukee battery adapter. After I bought the Milwaukee battery I made very minor modifications to exactor machine to fit the adapter. (See pictures). It made sense for me to do this because I have a lot of Milwaukee batteries laying around and don’t have to worry about having different charger and batteries. Just know this will definitely void the warranty so don’t have any guarantee expectations after doing this modifications!
After all set and done the machine works as it should and couldn’t be happier! Only thing I wish the machine allowed us to adjust the water pressure to put more water on larger stains.
