About Commercial Pressure Washers
Hallmarks of a commercial machine: triplex plunger pump, brass cylinder head, ceramic pistons, 1450 RPM induction motor, full thermal protection and replaceable seals. Expect 150–250 bar.
Top UK contractor picks: Kärcher HD 5/15, Nilfisk MC 2C, Comet KS 1900 Classic. Hot-water Kärcher HDS and Nilfisk MH equivalents add diesel burners for grease work.
Pricing runs £700–£4,000+ for cold-water, £2,500–£12,000+ for hot. Total cost of ownership is far lower than burning through cheap domestic units annually.
