Kärcher OC 6-18 Battery-powered middle pressure cleaner

Note: Battery and charger are not part of the standard equipment - while stocks last, until sold out.



Compact and mobile cleaning independent of the power supply - the battery-powered middle pressure cleaner OC 6-18 is ideal for quick and effective intermediate cleaning on the go or around the house. Simply connect the hose and you can start cleaning. With the flat jet nozzle, stubborn dirt on bicycles, camping or garden furniture, toys and much more can be quickly removed. The interchangeable battery (not included in the scope of delivery) can be used in all 18 V Kärcher Battery Power platform battery devices. Thanks to innovative real-time technology, the LCD display shows the remaining capacity during use, charging and storage.

Variant Kärcher OC 6-18 Premium Battery Set strednotlakový čistič

A practical thing, with a 2.5 Ah battery it can handle exactly 3 full tanks of water. Charging is very slow, for example from 30% to 100% it takes 230 minutes. You can buy a 5.0 Ah battery with a "quick charger", then it takes "only" 150 minutes.
Unlike the Bosch Fontus, the spray pressure cannot be adjusted (24 bar). The nozzle holders cannot be removed after they are clicked into the compressor, which is really stupid. Unlike the Bosch Fontus, it does not have a water filter. There are also some accessories, see the attachment.

Praktická vec, s 2.5 Ah batériou zvládne presne 3 plné nádržky vody. Nabíjanie je veľmi pomalé napríklad z 30% na 100% to trvá 230 minút. Batéria sa sama pomerne rýchlo vybíja aj keď nie je používaná. Odložíte 100% batériu do šuflíka, a za týždeň má už len 80%. Dá sa dokúpiť 5.0 Ah batéria s "rýchlo nabíjačkou", potom trvá nabíjanie "len" 150 minút. Pre porovnanie akumulátor Bosch 5.0 Ah sa nabíja 35 minút... Ďalšia vec: Bosch akumulátor je veľmi robustný, vydrží pád na betón z výšky 3 metre, kdežto Kärcher sa bohužiaľ poškodí, rozbije. Kärcher batéria má digitálny displej ktorý ukazuje úroveň nabitia, zhruba po mesiaci sa sklíčko toho displeja zarosilo a už nevidno čo displej vlastne ukazuje!
Na rozdiel od Bosch Fontus sa tlak striekania nedá nastaviť (24 barov). Držiaky na trysky sa po zacvaknutí do kompresora už nedajú dať dolu, čo je poriadna hlúposť. Teda nakoniec som tie držiaky nejako odtrhol, ale išlo to naozaj veľmi ťažko. Na rozdiel od Bosch Fontus nemá Kärcher filter vody. Kärcher sa dá použiť aj samostatne bez nádržky, pri Bosch Fontus je nádrž neoddeliteľná. Existuje aj nejaké to príslušenstvo, viď príloha. A na záver, Bosch Fontus je aktuálne o dosť lacnejší.

Variant Kärcher OC 6-18 strednotlakový čistič, batériový

The product I ordered was not the right one, so I returned the unused one. The seller said that I had used the product, although this was not true. After a long period of time, they refunded my money, but with a discount of €45. I am very disappointed and do not recommend shopping on this website.

Izdelek, ki sem ga narocil ni bil pravi, zato sem neuporabljenega vrnil nazaj. Trgovec je dejal, da sem izdelek uporabljal čeprav to ne drži. Po daljšem obdobju so mi vrnili denar vendar z kar 45€ manj. Sem zelo razočaran in ne svetujem nakupov na tej spletni strani.

SK Dobry den,

teoreticky ano, urcite je to setrnejsou volbou ako kefy v autoumyvarni, ale je treba ratat s pripadnym pracnejsim rucnym docistenim viac znecistenych miest (napr. diskov kolies a pod.).

PL Korzystam z tej myjki. Do samochodu polecałbym Ci jednak myjkę wysokociśnieniową Do roweru to trochę niebezpieczne, bo wysokie ciśnienie może wtłoczyć wodę w stery, support, itp Poza tym wypłukuje smar ochronny. Myjki średniociśnieniowe sa bezpieczne do użytkowania z rowerami. Pozdrawiam
