Here is a helpful solution to those hard to reach places!
Tape a cardboard tube to the end of your vacuum hose. Wrapping paper tubes work the best for this application. Tape the tube to the end of a vacuum cleaner wand to reach cobwebs in ceiling corners or dust on fans. Reach all the way under beds and furniture, or flatten the roll to vacuum narrow crevices. Make it a permanent dusting wand by wrapping it with duct tape, and it’ll stand up to years of use.
