Crevice nozzle Karcher 9.770-638.0 — narrow reach attachment for vacuum cleaners

Karcher crevice nozzle 9.770-638.0 is a narrow vacuum attachment designed to reach tight gaps and edges where standard tools cannot. The slim shape and rigid construction allow concentrated airflow for removal of dust, crumbs and small debris from between furniture, along baseboards, radiator fins and inside vehicle interiors. The nozzle connects to compatible Karcher vacuum cleaners and offers improved access and control for precision cleaning tasks in domestic and automotive environments.

Advantages

The crevice nozzle provides focused suction through a narrow outlet, enabling efficient debris extraction from confined spaces. Its compact design improves maneuverability and makes it easier to access corners, seams and narrow channels. The attachment is made to fit compatible Karcher hoses and wands securely, reducing air leaks and maintaining vacuum performance during use. The rigid profile preserves shape under pressure and supports precise positioning for targeted cleaning.

Suitable for

• Cleaning gaps between sofas, mattresses and bed frames
• Removing dust and lint from radiators and heating fins
• Detailing car interiors: between seats, consoles and door pockets
• Cleaning window frames, sliding tracks and narrow mouldings
• Accessing seams and crevices in appliances and furniture

Key specifications

• Attachment type: narrow crevice nozzle for focused suction
• Compatibility: designed for use with compatible Karcher vacuum hoses and wands
• Material and build: rigid plastic profile for shape retention and precise control
• Outlet shape: elongated slim opening for access to tight spaces
• Typical applications: domestic and automotive precision cleaning

How to use

Attach the crevice nozzle firmly to the vacuum cleaner hose or wand of a compatible Karcher model, ensuring a secure fit. Position the narrow end where airflow and suction are required, then move the nozzle along the gap or seam at a steady pace to collect dust and debris. For vehicle interiors, use small, controlled passes between seats and around trim. Empty or service the vacuum cleaner's dust container or bag and filters according to the vacuum manufacturer's instructions to maintain suction performance.

Usage recommendations

Use the crevice nozzle for dry debris and loose dust only; avoid suction of liquids, large hard objects or sharp materials that could damage the attachment or the vacuum. For stubborn dirt in narrow metal or delicate surfaces, combine the nozzle with a low-suction or variable-power setting on the vacuum where available. Store the nozzle clipped or nested with other attachments to prevent bending or exposure to high heat.
