How to Identify and Fix Common Vacuum Problems ?

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

If your vacuum always trips the breaker, you most likely have an actual electrical problem. Signs that indicate your AFCI breaker is tripping due to an electrical problem include: Frayed cords. If your vacuum cords are old, frayed or deteriorating, it could be producing dangerous electrical arcing.
A vacuum circuit breaker trips through an error like an earth fault, short circuit, over/under voltage. A contactor is usually performed in series through a fuse that provides to avoid fault current.
Why is the vacuum is blowing dusty air out of the back? Simple: the bag or canister is full and the vacuum has nowhere to store the dust it is collecting. Empty the canister or bag. If that doesn`t fix it, the vacuum filter needs to be cleaned or changed.
While different factors affect how long a system lasts, many central vacuums can last 20-30 years, or even longer, depending on how often they are used.
The culprit is often a leaking pressure vacuum breaker (PVB). 1) Wear and tear: Over a certain period of time, things just wear out. The same goes for a PVB. Undergoing normal use of pressure over time, a PVB is susceptible to leaks.
Current chopping in circuit breaker is defined as a phenomenon in which current is forcibly interrupted before the natural current zero. Current Chopping is mainly observed in the vacuum circuit breaker and air blast circuit breaker.
Vacuum circuit breakers have a steel arch chamber located in the center. They are symmetrically built and stacked in ceramic insulators. The vacuum interrupter maintains a vacuum pressure between 10 to 6 bar.
If the filter bag or canister is too full, it cannot pick up any additional particles and will simply jam or the motor will overheat and shut down. So, when you suspect your unit is about 75 per cent full, empty it!
Second, can you vacuum too much? Believe it or not the answer is no. Now, if you vacuumed continually 24 hours a day, yes, that would be too much. Vacuuming every day, or even a few times a day, is not going to create any long term problems.
Power Usage

The amount of power used by a central vacuum system is roughly the same as that of a portable vacuum cleaner. Yet, it has 3 to 5 times the power of a portable vacuum cleaner. You are getting more suction power, which translates into more efficient cleaning, at no extra energy usage.

Will a dedicated electrical circuit be required for a central vacuum power unit installation? Yes. It must be either a 15 amp or 20 amp circuit depending on the specific power unit you are installing.
This means there is a break in one of your appliances or circuit. Often, you can check for blown fuses yourself and change the fuse in the main fuse box. You should also keep track of what devices you have plugged into each socket. And make sure they`re not all overloading one circuit.
The primary cause of tripped breakers and blown fuses is a dirty air filter. One simple maintenance task any homeowner can handle is replacing their system`s air filter on a routine basis. Many experts agree that you should change your filter at least once a month during the peak of the cooling season.
The average lifespan for a circuit breaker is 30 to 40 years.
In fact, on average, old style vacuum breaker repair kits will last about 2-3+ years. (like this Standard Vacuum Breaker Repair Kit – Equiparts Part #08012), while new style vacuum breaker repair kits will last 3-4+ years (like this Hi-Performance Vacuum Breaker Repair Kit – Equiparts Part #08438.)
An air circuit breaker is a type of circuit breaker that uses air as the arc quenching medium. A vacuum circuit breaker is a type of circuit breaker that uses vacuum as the air quenching medium. ACB is suitable for low voltage range upto 450 volts. VCB is suitable for medium voltage range from 11 kV to 33 kV.
Power Surges and Spikes

A common occurrence in electrical components, voltage surges and spikes often cause an electrical circuit breaker to fail. However, the chances of circuit breaker failure can be minimized by equipping the electrical panel with a surge suppressor.

How Many Amps Does a Vacuum Cleaner Use? An effective vacuum cleaners use high-quality motors that provide sufficient suction and generate from 3.5 to 8 amps of current.
What is the difference between an Atmospheric Vacuum Breaker and a Pressure Vacuum Breaker? A pressure vacuum breaker (PVB) is designed to be under constant pressure. An atmospheric vacuum breaker (AVB) is NOT designed to be under constant water pressure.
Vacuum pressure is measured relative to ambient atmospheric pressure. It is referred to as pounds per square inch (vacuum) or PSIV. The electrical output of a vacuum pressure transducer is 0 VDC at 0 PSIV (14.7 PSIA) and full scale output (typically 5 VDC) at full scale vacuum, 14.7 (0 PSIA).
Full vacuum means the complete absence of pressure and is also called as Absolute Pressure or absolute Zero pressure. So Full vacuum would be 0 Psia.
“We would recommend vacuuming at least once or twice a week—and more often if we have pets—with the right tools to remove dust quickly and effectively,” Patel advises.
Frequent vacuuming remains one of the best ways to keep your home clean. If you don`t vacuum your carpet, the dirt will break down carpet fibers and create a breeding ground for dust mites and bacteria. In addition, your home will begin to smell musty from the dirt, mites, and other organisms settling into the fibers.
Remember to contract your abdominal muscles while doing this. Continue to breathe normally as you hold your belly in. You shouldn`t be holding your breath, which is a sign you`re not contracting your transversus abdominis and are “sucking in”. Try to hold this position for at least 20–30 seconds.

ANSWER : The power head requires 120 Volts. Some hoses have a receptacle in the handle for the power head plug, and the hose has a cord at the wall inlet end that plugs into a receptacle. Some hoses have a plug at the wall inlet end that plugs into a 120Volt receptacle built into the inlet. The hose plugs into this receptacle when you push the hose into the inlet. The power for this built-in receptacle is wired with line voltage when the system is installed.

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 have a Husqvarna Viking Designer sewing machine. The fuse blew in the machine and I am having trouble finding a replacement fuse. It is a T3.5/250v glass fuse. Please let me know where to find one. I have searched the internet high and low and can’t find one. Radio Shack has a 3.0amp 250v slow blow fuse whick seems to be the right dimensions. Willl that work. Otherwise, I am not sure what to do and can’t afford to take the machine to a repair show. Thank you.
ANSWER : That fuse will work no problem. There is no harm in trying it.
The machine probably requires about 2 amps or less under normal operation.
Being a 3.0 amp slow blow fuse, it will withstand short bursts of extra current when your machine gets temporarily overloaded.

Just make sure the machine is properly lubricated and runs freely. The fuse will definitely blow if your machine should get jammed or something like that.

I think I know where I can score some. Cost of postage only. 🙂

Unbeknownst to me, someone took the bag out of my Kenmore Progressive vacuum and failed to replace it. I have been vacuuming without a bag for months, and today the vacuum stopped sucking. When I opened up the front to replace the bag, tons of dirt and dust came pouring out. I thoroughly cleaned the vacuum, put in a new bag, but still no sucking power. Just dust coming from the rear vents where one of the filters is. Is the vacuum ruined, or is it a simple solution of buying a new filter?
ANSWER : Sounds like you need to buy a new motor. All that grit and dust will ruin a motor and I’m surprised it lasted as long as it did.
.This is where a vacuum that won’t run without a bag would have been nice. (Aerus for one)

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t
ANSWER : The belt heats up due to the friction, as well as being in contact with the shaft of a hot motor. It is normal.
