1. What is your budget?
Not to waste time comparing many models that do not fit into your budget, you had better set from the beginning the maximum amount that you plan to spend on your vacuum cleaner. It is important to choose a model with good value for money. As with all purchases, a quality vacuum cleaner will generally cost more, but will often be more profitable in the long term. Finding vacuums with good value for money? Best shark vacuum is one model that you should take a look.
2. What type of vacuum cleaner to look for?
A subcategory of cylinder vacuum cleaners consists of compact vacuum cleaners. These are small-sized canisters, which are lighter and easier to carry. Some are also equipped with a carrying strap, to put them on the shoulder or back up the stairs for example. The compact vacuums are convenient to small surfaces (studio) or homes with floors (duplex …). Their disadvantage is their size: The tank capacity (bag or dust compartment) is reduced, and the engines are less powerful and often less durable than conventional cylinder vacuum cleaners.
The vacuum cleaners are pushing ahead. They can be good for people with back problems, applied only on flat floors (no stairs for example). They usually have no son, and are equipped with a battery. Their motors are undersized compared to sled vacuum cleaners, and they are therefore to be accorded to small areas.
There are also other types of vacuum cleaners, which correspond to specific applications and are treated for clarity in separate articles:
- Robot vacuums: This is a recent innovation. They travel alone in your home.
- Centralized aspiration: the idea is to build a central fixed suction in your house, connected to an air duct system. Then simply connect the suction hose on inlets distributed in different rooms.
- The hand vacuums: they can clean crumbs on a table, in a car, or cleaning pet hair on furniture.
- The bucket vacuum cleaners: this type adapts to the specific needs and uses, and rarely goes to the general public.
3. What is suction efficiency?
Recently, one of the best indicators of the performance of a vacuum cleaner is useful output. In Watts, it should not be confused the power consumption of the vacuum cleaner, which increases the electricity bill. Similar power consumption, vacuum cleaners with different yields will not have the same suction power.
In summary, the former performance indicators, which are sometimes still supplied by the manufacturers, are:
- The output power: it is between 150 W and 400 W in general. It is the product of the depression created by the vacuum cleaner and the suction air flow.
- Depression: the pressure difference that can be generated by the vacuum cleaner, and its ability to raise dust. It is important for carpets and rugs. Depressions vacuums range from 25 kPa (kilo Pascal) to 40 kPa.
- Flow: It represents the volume of aspirated air per second. It is important for hard floors. It varies between about 30 L / s to 50 L / s. In the technical data it is often expressed in dm3 / s: it is the same: 1 L / s = 1 dm3 / s.
Nowadays, things are much simpler thanks to a new European regulation which requires manufacturers to indicate in an energy label with the following information:
- The energy efficiency of the vacuum cleaner, graded from A to G, which increases with the average removal efficiency and decreases energy consumption. The best vacuums have an A.
- The level of filtration vacuum, denoted from A to G. The vacuum cleaners equipped with HEPA filters and good joints will tend to have a higher score on this point.
- Cleaning performance on carpets, labeled A to G. It must be at least 70%.
- Cleaning performance on hard floors, labeled A to G. It must be at least 95%.
4. Vacuum cleaner without bags or bags?
This is one of the most important questions when buying a vacuum cleaner.
The bags vacuums have been the only choice for a long time and are the traditional models. Their operating principle is simple: disposable bags, paper or fabric for newer, serve as filters and block dust and debris. Over time, these bags are filled and must be replaced. The magnitude of the bags replacement cost is 15 € per year.
More recently, models of vacuum cleaners without bags were introduced on the market. These vacuums use the principle of cyclonic suction, which is to create a “cyclone” or air vortex that sends centrifugal force dust into the tank. A washable or replaceable filter cloth may in some cases be complementary to the filtration system.
The experience and the tests show that in general the classical models with bags are better and cleaner. Indeed bags once filled can be discarded simply, while bag less vacuum cleaners empty the tank above the garbage and cleaning can be re-dispersed part of the dust.
