Understanding quite a number of confusing specifications is amongst the most challenging aspects of choosing a new vacuum cleaner. First of all, consumers want floor cleaners offering the most effective cleaning ability. And a lot consumers typically equate cleaning ability with «power» or «suction».
Cleaning ability is not just about power and suction, even though these attributes are important elements of vacuum cleaner performance. With some information and education, it will be easy to search through the numbers and know what the specifications mean and the ones that are very important for you.
Unfortunately, there is no single rating that indicates cleaning ability. However, there are many of primary specifications, that anytime clearly understood, allow customers to make educated decisions concerning which vacuum could have the best cleaning ability.
These primary specifications include watts, amps, volts, water lift (or sealed suction), horsepower, air watts, and airflow.
In addition there are a number of other, secondary specifications that influence cleaning ability that we’ll also examine. Such as filtration, cleaning tools (agitation), capacity, quality, noise, features and expense.
In order to make experience of this we first need to comprehend the basics of how a hoover vacuum works.
All vacuum cleaners operate based upon air flowing from the opening with the cleaning head or tool, through the vacuum along with the bag and filter system and then out of the exhaust port. This airflow is made with the vacuum motor, which also might be called the suction motor.
The vacuum motor contains electrical components connected to a fan or multiple fans. When the fans spin, a partial vacuum is generated along with the pressure within the cleaner drops underneath the ambient (or existing) air pressure within the room. Because air pressure is higher outside the vacuum cleaner than inside, air rushes through the cleaner.
So, you can easily notice that the vacuum motor will be the heart of the cleaner. In the end, the better powerful the motor, the greater the pressure differential and so the greater number of suction and airflow, right? And is particularly for that reason that a lot of the specifications you see concerning cleaning ability relate either directly or indirectly on the motor.
But here’s where it gets tricky. Specifications for components including the motor do not really connect with the performance of your entire vacuum, and they are only a part of the story.
Let’s look into the primary specifications one by one:
The input power in the vacuum motor is measured in watts. Even if this specification doesn’t consider the efficiency of the motor, the amount of fans or maybe the overall vacuum design, motor wattage is actually a valid way to evaluate and compare the potency of the motor.
Whilst the ideal comparison is motor input power in watts of Product A in comparison with motor input power in watts of Product B, some manufacturers tend not to provide motor input power specifications in the form of watts but instead rate the entire vacuum in amps. This will make it tough to compare across brands.
However, you can convert amps to watts from the formula, amps x 120 (volts) = watts. Or conversely, you can convert watts to amps from the formula, watts/volts (always 120) = amps. For example, a 1400-watt motor converts to 11.67 amps (1400/120=11.67).
Comparing machines rated in amps with those rated in watts will not be a precise comparison because manufacturers which are using watt ratings typically rate the motor only while amperage ratings use the total electrical use of the cleaner including the motor within the power nozzle (the motorized revolving brush cleaning head), bulb, etc.
