When facing the prospect of cleaning dirty carpets, we all need a good solution.  Which is superior:  Shark Rotator Vacuum or the Dyson?  The choice of vacuum cleaners can be so overwhelming to many because of the confusing specifications and sometimes, frankly, outrageous claims that manufacturers make about their respective machines.  Years ago, the famous British novelist Graham Greene wrote  a humorous, satire highlighting the complexity of vacuum machines.  In his spy novel, “Our Man in Havana,” Greene showed how the complex plans for a vacuum machine could resemble the fictitious blueprints for an enemy country’s nuclear power plant! The point is that vacuum machine technology can be frankly overwhelming to the general public.  Both the Shark Rotator and the Dyson have great qualities. But when customers focus on the qualities most important to them, the choosing of a vacuum cleaner becomes easier.

Many customers focus exclusively on suction power.  That’s a mistake.  Certainly, this factor is important for customers to determine which machine can get the dirt out.  Most Dyson models seem to have more suction power than the Shark Navigator.  But beyond that, customers should consider whether there’s a point of diminishing returns in suction power.  Perhaps a machine with too much suction could actually damage carpets. When there’s too much suction the machine might cause damage to more delicate types of carpets.  Even if the damage is small, if the carpet is subject to numerous small traumas, the damage could be compounded.  The carpet that customers intended to clean could in fact become destroyed.  Not all surfaces require high sucking power. The better realistic test for customers is to consider the types of surfaces they want to clean. Would all of them benefit from the higher suction power offered by one machine.

Customers can consider some practical other points of comparison.  The Shark Navigator has a cord length of 30 feet.  Most Dyson models have longer cord lengths.  That often makes the machine easier to use. Instead of more frequently having to stop vacuuming to reinsert the power cord into a new socket, the longer cord may allow for easier, faster cleaning experience.

Next, customers need to consider the quality of the customer service, including warranties.  Dyson prides itself on its customer service.  Both the Shark Navigator and the Dyson seem to have high quality customer service. Some customers of each machine have reported satisfaction with each company.

In addition, customers need to study the scope of the warranties carefully.  Which parts are covered by the warranty and for how long? In any machine using moving parts, one expects the parts to deteriorate over time.  If securing replacement parts comes as part of the vacuum ownership package, customers should consider how difficult it is to secure the parts.  Many companies place such onerous restrictions on accessing the warranties that the warranty itself becomes useless.  If the only way to get the benefit of the warranty is to jump through many proverbial hoops, there’s no point to the warranty.

As a related concern, customers should pay attention to the cost of replacement parts.  In this respect, Dyson seems to have the advantage because of the fewer parts. But this should not be the end of the inquiry. There’s the issue of how frequently the parts need to be replaced. And also, customers should consider the issue of the cost of the replacement parts.

While vacuum cleaner specifications can sometimes overwhelm ordinary consumers, the choice between the Dyson and the Shark Navigator does not have to be so distressing.  To make the best decision, customers should focus on the issues that are important to them.
