About Professional Pressure Washers
Professional models share the triplex pumps and brass heads of industrial units but stay single-phase and around 150–200 bar. Ideal for window cleaners, valeters, soft-wash crews and gardeners.
Top sellers: Kärcher HD 5/15, Nilfisk MC 2C, Comet KS 1900, SIP Tempest TP750. Expect £700–£2,500 cold-water; £2,500–£6,000 hot-water.
Worth the spend if you wash for a living. For weekend domestic use, a £200–£400 prosumer like the Kärcher K7 saves money without compromise.
