How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
Conventional vacuum cleaners mainly use universal motors powered by a mains supply. Nowadays, brushless DC (BLDC) motors powered by a DC power source are increasingly used for cordless cleaners. BLDC motors are available with three-phase and single-phase configurations, which are controlled in different manners.
KEY TAKEAWAYS: Bagged vacuum cleaners comprise six main parts, including angled fan blades, a porous bag, an exhaust port, an intake port, an electric motor, and a housing unit. Extra attachments include brush heads, vacuum hoses, and angular suction tools.
As for the commercial sector, almost every central vacuum operate with two motors.
UNITS THAT EMPTY FROM THE TOP: The motors are on the bottom of the vacuum unit. Remove the unit from the wall, turn it upside down, and open the bottom or bottom section to reveal the motor. Each motor has two or three wires that may run to other wires, relay, or mini-breaker.
The first, and arguably most important, part of the vacuum cleaner is the suction motor. This is what creates the vacuum pressure and suction power by utilizing a rotating motor fan.
A vacuum cleaner, also known simply as a vacuum or a hoover, is a device that causes suction in order to remove dirt from floors, upholstery, draperies, and other surfaces.
What does a vacuum pump do? The vacuum pump aims to provide a vacuum to several different places in the engine bay. The booster on power brake systems is one of the critical components that require a vacuum. The vacuum pump makes sure that the booster stays under constant vacuum to provide adequate braking force.
Dual-motor vacuums use one motor to create suction and a second motor to turn the brush. Two motors make units heavier, but it also gives it more suction allowing janitors to suck up a majority of dust and dirt in one pass. In addition, machines break down less because the separate motors are protected from debris.
Any negative pressure significantly below standard atmospheric pressure (760 Torr/mmHg, 29.9 inHg or 14.7 PSI) is considered a vacuum. Vacuum quality is subsequently divided into ranges that are somewhat arbitrary but primarily based on the equipment needed to achieve or measure it.
There are three main types of central vacuum cleaner motors: the flow through (or “through-flow”) motor, the peripheral bypass motor, and the tangential bypass motor. While each type of motor offers powerful suction, the way they channel air through their systems is what sets them apart from one another.
Most vacuum machines are equipped with motors that use anything from 500 to 3000 watts of electricity, with the typical unit using around 1,400 watts.
The most common problem with a vacuum cleaner is also the easiest to remedy: clogs in the hose or attachments. Also the electrical cord, motor, switch, fan, brushes, and motor bearings can all need repair or replacement.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
Electric motors are commonly used in a wide range of applications, including vacuum cleaner. The electric motor is a crucial component of the vacuum cleaner, providing the suction power necessary to effectively clean floors and other surfaces.
A vacuum is a space devoid of matter. The word is derived from the Latin adjective vacuus for “vacant” or “void”. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure.
Suction is the measure of pressure created by a vacuum motor measured in inches of water lift. Air flow is the measure of air volume flowing through a system measured in CFM or cubic feet per minute.
Perfect vacuum has a pressure of 0.0000 mbar absolute. In vacuum technology, the absolute pressure is always indicated, so that, in general, the index “abs” can be dropped.
In general, standard motors will not survive in a vacuum of 104 Torr or lower for very long. The primary reason is that the lubricants and the insulation materials will evaporate, a phenomenon known as outgassing.
Inside the vacuum is an electrical motor, which converts electrical energy into mechanical energy.

I have a Kirby G4 Vacuum Cleaner – MOdel G4 D. I have never had any problems or repairs done to it in the past ten plus years that I’ve had it. This is an upright vacuum. I was vacuuming the carpet floor and was not having any trouble at all. I switched the vacuum off and moved it into a different room. When I tried to turn on the vacuum, it would not turn on. I checked with different outlets, used both front attachment and hose attachment. Checked the front part of the motor/ spiral case. This

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

I purchased a Eureka C4910 last year and have a question that I am hoping you can answer.

There are two motor actions with this vacuum, 1) the vacuum suction, and 2) the beater bar. The action of the beater bar is that motor is supposed to automatically shut off when the handle is in the complete vertical position assuming the vacuum is stationary, but then turn on when the handle is tilted toward the floor, assuming the vacuum is moving back and forth.

The beater bar motor turn-on mechan

ANSWER : Good day!

Normally when the motor is easily moved back and forth means that it have a proper lubrication,proper alignment and no clogs.

When the motor and the belt is OK the problem could be on electrical wiring and switch.

If found electrical switch burned out you need to replaced it because when the switch is burn the contact of that switch is open even you turn it ON.that’s why the motor is not function because the voltage is not pass through the circuit because of open switch.You need to replaced it.
And check some fuses if any and other burned electrical wire.Replaced it also.

Thank you and don’t forget to rate my answer.

Bad Motor I have purchased two of the Kenmore direct drive beltless systems with Progressive systems. The first died after a year, the vacuum motor start making a grinding noies. I pulled the side HEPA filter and could see a fine coating of graphite like dust. Took it to a vacuum repair shop. They said the brushes were going and thus the motor was shot. I liked the vacuum and bought a second, 1 year later the motor is making a slight noise that and removing the HEPA filter I find a slight metall
ANSWER : That dust is from the carbon brushes on the motor. You may need to check them, and also clean out the motor compartment. A slight noise could be a motor bearing starting to go. Does the smell like rubber or electrical. If rubber, then the belt has stretched and needs to replaced. If electrical, then something is causing the motor to run hot, like a clogged filter, or it could be a motor going bad.

The female part of the catch which holds the lid to the accessories compartment closed has broken. This forms part of the handle to the vacuum cleaner.We’ve had the vacuum for less than a year but cant find the receipt so i think i will just have to pay for the parts. What is the part called that i need or the part number and where can i get it from. Many thanks
ANSWER : Even if you do not have the receipt you are still entitled to one or two year warranty.
Since appliance sales are recorded after-sale by manufacturer, you need to contact the manufacturer to validate the warranty and get the replacement.
