As they are so lightweight and manoeuvrable, hand vacs are perfect for small surfaces. They are particularly useful and practical for hoovering up crumbs and other dirt after meals.
You can take this vacuum cleaner anywhere in your house and with time some parts may start to wear out. Often the battery becomes less and less efficient and you have to replace it. If your vacuum cleaner is not sucking anything up any more, the bag may be full, the hose may be clogged or the motor might have broken down due to sucking up too many fine particles (flour for example).
In order to keep your vacuum cleaner and performing beautifully, it is essential to maintain it. Don't wait, for example, for your bag to fill to bursting before changing it. You should regularly remove the dirt that accumulates on your vacuum cleaner's brush (hair, threads, etc.).
