Using this Volta Gemini vacuum hose is easy. First, connect the end with a 39.5mm diameter to your vacuum cleaner. Make sure to use the two opposing push - to - release clips to secure it properly. Then, attach the bent end with a 33.9mm diameter to a standard 35mm pipe. When using, avoid sharp bends or kinks in the hose as this can reduce suction power. For maintenance, regularly check the hose for any blockages. If you find dirt or debris, simply remove it and clean the hose with mild soapy water. Dry it thoroughly before using it again. With proper use and maintenance, this hose will serve you well for a long time.
