Since their invention in the late 19th century vacuum cleaners have become an essential domestic item around the globe. While the basic early vacuum cleaners were unwieldy and heavy, they were an instant success and have evolved into the sophisticated, many-featured models that we are familiar with these days.

The first electric vacuum cleaner, made by Nilfisk, appeared early in the last century. However, vacuum cleaners didn’t truly become popular as a consumer item until after the Second World War when they became a must-have item among the middle classes. The increased demand and sales resulted in ever more sophisticated and lightweight models, at more affordable prices.

These days there are two basic types of vacuum cleaner available on the market – upright and canister – and each offers its own good points and bad points.

Upright vacuum cleaners – These have a cleaning device at floor-level with a handle and bag for the dust attached. They usually have wheels and are rolled ahead of the user. Upright cleaners are most suitable for bigger, open rooms and are popular because the user can remain upright while using.

However, these vacuum cleaners do have their disadvantages. The main disadvantage is that they do not operate efficiently in tight areas. They are difficult to move beneath and around furniture, although some models do come with hoses which helps address the problem. Upright cleaners sometimes do not have retractable electric chords, they are heavy and unwieldy, and are difficult to use on staircases.

Canister vacuum cleaners – Canister cleaners are comprised of a cleaning unit and dust receptacle which are contained in a ‘canister’, with a long, flexible pipe which is attached to the vacuum head. These are a common choice with consumers because they are lighter and the design makes it much more convenient to clean on stairs, in tight areas and in corners. Canister vacuum cleaners also come with a variety of head fittings so they are much more versatile. For example, there are particular fittings for cleaning your car or your curtains.

However, canister cleaners have their disadvantages too. They can be awkward in their own fashion as you need to pull the canister behind you. Also, the dust bags are often smaller so will require more frequent changing.

Although upright and canister vacuum cleaners have not changed dramatically in basic design over the past number of years, several optional extra features have been added to both designs. These include wet/dry or pneumatic vacuums that can be utilized to clear up wet spills, as well as normal dust.

Another example was the Dyson vacuum cleaner, which did away with the need for bags, instead channeling the dirt into a plastic container that can be detached and emptied.
