Professional cleaning teams are increasingly selecting specialized pressure washer accessories to improve efficiency across vehicle care, surface washing, and drain maintenance. The most requested products include high-pressure sewer drain hoses, foam lances, adjustable pressure washer guns, undercarriage cleaners, and universal water outlet connectors.
Each accessory addresses a different stage of professional cleaning. Sewer drain hoses help clear difficult blockages, foam lances support thorough pre-washing, adjustable guns provide flexible water control, undercarriage cleaners reach hard-to-access vehicle areas, and quick-connect adapters make equipment changes faster.
A high-pressure sewer drain hose is designed for flushing grease, hair, silt, and accumulated dirt from kitchen drains, bathroom floor drains, and underground pipelines. The listed model has a 5.5 mm inner diameter and a 10.3 mm outer diameter. It uses PVC and polyester materials and supports a working pressure of 18 MPa, or 2610 psi.

Available hose lengths include 5 m, 7 m, 10 m, 15 m, 20 m, 25 m, and 30 m. Connection choices include G 1/4 and G 1/8, while the product information also identifies a 60° specification. With a minimum order quantity of 10 pieces, full inspection, and an indicated delivery period of 7 to 10 days, this accessory is suited to professional pipeline dredging projects.

Foam lances apply thick, adherent foam that helps loosen dust, bird droppings, insect residue, and road film before rinsing. They are useful for cars, motorcycles, recreational vehicles, exterior walls, and tiled surfaces. By extending the contact time of the cleaning solution, a foam lance can make the following rinse stage more effective.
Adjustable pressure washer guns give operators greater control over water spray patterns and cleaning intensity. They can be used for vehicle bodies, courtyard floors, balconies, construction equipment, and other areas where different levels of rinsing force may be required.
Undercarriage cleaners direct high-pressure water beneath vehicles to remove mud, gravel, and road sludge from chassis components, suspension areas, and wheels. Universal water outlet connectors complement these tools by enabling faster switching between pressure washer guns, foam lances, pumps, and other accessories.
