Carpet cleaning machines are sold as shampooers, extractors and steam cleaners, and the three are not interchangeable. The naming confusion is why sites buy the wrong machine and then conclude that carpet cleaning does not work.
We stock 235 Karcher items, and the range is wider than most buyers expect. Karcher builds pressure washers, vacuums, steam cleaners, carpet machines and floor scrubbers — and, more importantly for long-term ownership, individual parts for all of them.
The barrel or canister format remains the most common commercial vacuum shape, and the reason is stability rather than suction. A canister sits on the floor and follows the operator, which suits long cleaning runs.
A sweeper is the cheapest way to cover a large hard floor, and the category splits sharply by how the machine is moved. The choice is decided by floor area and aisle width rather than by cleaning performance.
Car seats are upholstery in the hardest working position: foam underneath, thin fabric on top, and a foam core that holds water for days. That is why the sequence matters more than the product, and why a wet seat becomes a mould problem in a week.
A fridge that smells is rarely a cleaning failure on the shelves; it is usually the drain tube, a door seal or something spilled behind the crisper. The visible surfaces are the easy part, and they are the ones most people clean.
A bathroom or kitchen exhaust fan rarely fails; it slows down. Dust packs the blades, grease coats the grille, and the airflow drops until the mirror stays fogged and the mould starts in the corner above the shower.
Concrete is a surface with a paste layer on top, and that layer is what looks clean when it is intact and looks permanently dirty once it has been blasted away. Getting the nozzle, the chemistry and the sequence right matters more than pressure.
Concrete is porous, so an oil stain is not on the surface; it is in the top few millimetres. That is why wiping makes it worse, why water alone does nothing, and why the sequence starts with absorption rather than chemistry.
