The Karcher SE 5.100 is a spray extraction purifier that cleans all floors that require a deep, hygienic cleaning. Ideal for people with a (dust) allergy. Water penetrates the carpet with high pressure. You immediately remove the dissolved dirt. You can remove grease, odors and dirt very effectively. All the dirt disappears in the 4 liter water tank, which you simply empties above the sink. In addition to the standard squeegee, you also get attachments for streak-free cleaning of natural stone floors, tiles, linoleum and synthetic floors. If you want to use the Karcher SE 5.100 as wet and dry vacuum cleaner, without first spraying clean water, remove the clean water tank beforehand. The tank for the dirty water can remain.
