Tip & How-To about Vacuums

What to do when your vacuum brush stops spinning

Household vacuums come in all shapes and varieties, but many of them are similar on the inside. There is often a brush running across the length of the vacuum's nozzle, and it spins as the vacuum runs to help **** up debris. But sometimes the brush will stop running, and you'll notice a severe decline in your vacuum's performance.

Usually when the brush stops spinning, it's because something inside the vacuum is binding it up. Dirt can get lodged inside, and hair can get wrapped around a shaft. If there is too much pressure, the drive belt can even snap.

You can usually see and clean the brush just by turning the vacuum upside down, but to get to the other internal parts you have to take the vacuum apart. On canister vacuums, this is usually pretty easy because it's just the nozzle that needs to come apart. Full-size vacuums can be taken apart as well, but the process can sometimes be more involved.

If you can get the nozzle or the vacuum's base apart and get to the parts inside, you should see the brush (which is part of a long shaft), a drive belt, and some sort of mechanism that drives the brush, which is commonly a paddle or a motor.

Hair can get caught up in any of these components and cause them to not be able to spin, as can dirt and other debris. If you clean all of the components out and put the vacuum back together, it should work just fine. The brush, over time, may become frayed or damaged, and the drive belt sometimes will snap, but otherwise a good cleaning will usually make your vacuum run as good as new.

when do you replace the brush on a vacuum cleaner


Replace when the bristles are worn or frayed or if they are not stiff. To check the length of the bristles, make sure your vacuum is unplugged, lay it upside down and lay a card or straight edge across the bottom plate to see how much bristle sticks out. If it's even the the bottom plate it's time to replace it.

there is a clog. check the hose, and the entry to the canister, check the holes inside the canister and check / clean your filter. also remove any threads/ animal hair from the brush so i can freely grab the carpet :)

no power. electric is OK. system will not turn on. Please help


Detach the vac itself from low voltage thin wiring leading to the house. With the vac plugged into power, try the manual switch and then try shorting across the low voltage exterior terminals with a rubber gripped set of pliers.
If you can hear a clicking inside, this is the vac's relay trying to start the motor. If the vac is more than 5 years old , or used more than 2 hours a week, you may need new carbon brushes, or a motor overhaul or replacement depending on wear. Carbon brushes are specific to the motor model # inside the vac, most often an AMTEK Lamb motor.
If you need brushes, the motors comutator should also be inspected for excess,wear, like gap ing between its conatct segments and "apple core" shaped wear
.
You you have a meter and can test for continuity across the motor leads, do so and post back.

If you don't have a meter, you will likely want to lift the vac off the wall after these checks and take to a repair shop, saving $$$$ for a house call...

Motor runs fine and hose not clogged will not pickup dirt


This may sound silly, but have you checked the belt? A lot of Eureka vacuums use the vac motor to run the brush, and if the brush is not running the vacuum won't pick up. Another thing to check is the condition of the fan blades.. if they get worn they will push air out of the exhaust ports, but not push enough air to pull the dirt into the vacuum bag. Another thing to check is the length of the bristles on the brush... you can change a lot of the bristle strips and save the cost of a whole brush roll.. All of these fixes are under $10.00 (Belt: $1-2, Brush Strip $3-6, Fan $5-10) at most places.

Hoover Windtunnel not picking up as well


There is a height adjustment on these vacuums and they are set to adjust in the "handle up" position". It will appear that the adjustment is doing nothing when the handle is up, but the setting will take affect when the handle is lowered.
You can check the brush length with a pen or pencil. Turn the machine over so that the brush is visible and run the pen or pencil flat across the bottom plate. Any where the brush is extending outward, your pencil should contact the bristle. If not, then the agitator should be replaced.
Also, check to make sure that the agitator is rotating freely and that the filters and bag are allowing for adequate suction. The machine will only pick up if the air flow is sufficient.
