There was a period not to way back when when a vacuum cleaner was basically the same machine no matter where or how it was ordered. In past times, your choice on what hoover to get was based more on the "extras" the salesman presented but more often than maybe not, it was the funding arrangements which were available. 

Like today, many people could ill pay the extra expense of replacing home appliances, what few which were available. The vacuum cleaner nevertheless was one device that was considered almost a necessity once it was used, particularly with the arrival of wall to wall carpet. 

Several homes pre-1960 didn't have wall to wall carpet but rather relied on rugs for floor coverings. These large carpets could be applied for to the backyard, hung over a fence or clothesline and beaten with a carpet beater to eliminate surface in earth. 

Cleaning appliances removed the necessity to just take rugs out of the home for cleaning. Today but, there are many carpet cleaning systems available. Two of the very most common forms of vacuum systems include bagless and HEPA filter. 

Both systems have the champions and like everything else have their positives and negatives. The positive with HEPA filtration is that small particulate dust is better captured. This allows for a exhaust and theoretically, a cleaner indoor environment. The bad with HEPA sort filters is that because the finer dirt particles are captured by them, they often need more frequent bag or filter replacement. Still another possible issue is that as the HEPA filter reflects more soil, in addition it tends to drop some suction power because the filters complete. 

Bagless vacuum cleaners are exactly what the name suggests. Bagless machine gear usually includes a cup or hard plastic box that captures the dirt all through use. This makes clearing a lot easier and the quantity of consumables like cleaner bags and filters is a lot less. 

Consider not only the technology but the simplicity of use, common quality of the apparatus, weight if you should be planning to take it up and down stairs, etc. Onboard tools are nice but why carry around all that excess weight when not needed. Every machine engineering has their share of people who hate it and people who love. The important thing is to find the vacuum you want. [http://plinky.com/people/maidsoflondon small blue arrow]
