The principle used by all vacuum
cleaners, whether modern or old, is basically the same: they all use a motor to
power a component that creates negative pressure to lift dirt and grime from a
surface, to transfer the dirt collected through filters and to deposit the
debris in a bag or a container. However, modern vacuums are much more varied,
much more versatile and much stronger than they used to be – here are some of
the most notable developments that differentiate old vacuums from modern
machines:
- Filtering efficiency – while most old vacuums used only one or two pieces of felt or foam placed where the debris-laden air enters the appliance, modern vacuums use much more sophisticated filters, such as High-Efficiency Particulate Air (HEPA) filter that removes even the tiniest allergens and dust particles from the vacuumed surface;
- Dry/wet vacuums – these sophisticated appliances can be used to clean up both dust and liquids;
- Robots – the most modern vacuums move automatically around the space that they are programmed to clean, removing dust and dirt from the surfaces systematically, then returning to their docking station when they are done;
- Power – modern vacuums are much more powerful than the old ones used to be, and shark vacuum repair from a Broomfield vacuum shop is relatively easy and inexpensive compared to older models.
