The dictionary is no help. A web search links it to a home steam cleaning product on kaercher.com, but I'm not sure how. Is it a product type, or the activity of steam cleaning, or...?
ケルヒャー is a transliteration of the company name Kärcher. At least in Germany, the brand name is almost synonymous with their high-pressure cleaners. (Like Sellotape or Xerox or Velcro.)
The resulting word is actually pretty close to the original word (a German surname)
Kärcher [[kɛʁçɐ]]
ケルヒャー [[keɺɯçaː]]
(closer than what would be possible in English, at least).
It is the name of a German company which produces and sells cleaning devices.

Seems to be the name of the company rather than a word itself.
