3-in-1 handheld vacuum cleaner with blower - This cordless handheld unit combines vacuuming and blowing for efficient multi surface cleaning. The front end handles suction while the back end acts as a blower, making it suitable for dust, pet hair, and some hard-to-clean debris in cars or homes. Cordless design with a C-type rechargeable battery - Large-capacity rechargeable battery delivers strong suction and extended run time. Without cords, you can move freely on stairs, in kitchens, cars, and tight corners, and you can store it easily in any available space. Reusable and washable filter with a secure dust cup - Equipped with a washable and reusable HEPA filter and a dust cup. The dust cup uses a double buckle design to prevent detachment during use. It can be rotated off for quick emptying and cleaning after use. Tip: if suction drops or the filter is clogged, clean the filter promptly to restore performance. Three versatile nozzle accessories - The vacuum includes 3 nozzles for different tasks. A narrow nozzle reaches gaps in car doors and seats; the brush attachment combines suction with wiping for dust on sofas, footstools, carpets, and keyboards; and an airflow-focused nozzle cleans fine dust in tight spaces, with the option to wipe and blow using a brush. Practical use scenarios - Car interior cleaning: remove dust and pet hair from seats, mats, and cup holders, including tight gaps. - Home and office quick touch-ups: clean crumbs on sofas and carpets, and clear dust from keyboards and desk crevices. - Stairs and hard-to-reach corners: maneuver easily around furniture and in narrow spaces where a corded vacuum would be cumbersome.
