Understanding a sizable number of confusing specifications is one of the very most challenging areas of selecting a fresh vacuum cleaner. First and foremost, consumers want vacuum cleaners to offer the best cleaning ability. And most consumers typically equate cleaning ability with "power" or "suction.

drmichaelcurtin.com cleaning ability is not just about power and suction, although these attributes are important components of vacuum performance. With only a little information and education, you will have a way to sift through the numbers and better know what the specifications mean and what those are important to you.

Unfortunately, there's not one rating that indicates cleaning ability. However, you can find several primary specifications, that after being clearly understanding, allow consumers to make educated decisions concerning which vacuum can have the best cleaning ability. These primary specifications include watts, amps, volts, water lift (or sealed suction), horsepower, air watts, and airflow.

There are also several other, secondary specifications that influence cleaning ability that we'll also examine. These include filtration, cleaning tools (agitation), capacity, quality, noise, features, and cost. To be able to seem sensible of this we first need to comprehend the fundamentals of what sort of vacuum works.

All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum and the bag and/or filter system, and then out the exhaust port. This airflow is created by the vacuum motor, which also might be referred to as the suction motor.

The vacuum motor contains electrical components attached to a fan or multiple fans. When the fans spin, an incomplete vacuum is done and the pressure in the vacuum drops below the ambient (or existing) air pressure in the room. Because air pressure is higher away from vacuum than inside, air rushes through the vacuum cleaner.

So, it is easy to understand that the vacuum motor is the center of a vacuum cleaner. After all, the better the motor, the greater the pressure differential and which means more suction and airflow, right? And it is for this reason that all the specifications you see concerning cleaning ability relate either directly or indirectly to the motor.

But here's where it gets tricky. Specifications for components like the motor do not necessarily relate solely to the performance of the entire vacuum, and therefore are only a area of the story.

The input power of the vacuum motor is measured in watts. Although this specification doesn't take into account the efficiency of the motor, how many fans, or the overall vacuum design, motor wattage is really a valid method to evaluate and compare the ability of the motor.

While the ideal comparison is motor input power in watts of Product A compared to motor input power in watts of Product B, some manufacturers do not provide motor input power specifications in the proper execution of watts but instead rate the entire vacuum in amps. This may ensure it is hard to compare across brands.

However, you are able to convert amps to watts by the formula, amps x 120 (volts) = watts. Or conversely, you are able to convert watts to amps by the formula, watts/volts (always 120) = amps. As an example, a 1400-watt motor converts to 11.67 amps (1400/120=11.67).

Comparing machines rated in amps with those rated in watts is not an exact comparison because manufacturers which can be using watt ratings typically rate the motor only while amperage ratings utilize the total electrical consumption of the vacuum such as the motor in the ability nozzle (the motorized revolving brush cleaning head), light bulb, etc.

This means that a Power Team (a canister vacuum with an electric nozzle) with a specification of 12 amps could be quite comparable to another Power Team with a 1200-watt motor that converts to only 10 amps.

This is because the ability nozzle motor consumes 1.5 amps, the bulb uses additional amperage, and so on. So, if we subtract the amperage utilized by the ability nozzle motor from our 12 amp machine, we develop 10.5 amps for the motor and light bulb. In this example, the 2 motors both have ratings of very near 10 amps, and therefore, equivalent motor input power.

Therefore, it is better to either compare motor input power in watts of both machines or when you have to compare a device rated in watts with one rated in amps, try to obtain the amperage rating of the motor only instead of the entire vacuum cleaner. Then you're able to convert this to watts and have a meaningful comparison.

A really common vacuum specification is amps. The amperage rating designates the utmost quantity of electrical current utilized by all the vacuum cleaner's electrical components when operating. The largest consumer of electrical current could be the vacuum motor, however, the amperage rating includes all the electrical components, such as the vacuum motor, the ability nozzle motor, the light bulb, etc.

The maximum amp "draw," (the number of amps the vacuum uses when running) allowed for just about any appliance that plugs into a standard household outlet is 12. drmichaelcurtin.com therefore, if you see amperage ratings above 12, see the fine print, as they are not true amperage specifications however many other manufacturers developed "performance ratings" designed to create the impression of a better vacuum cleaner.
