8 Easy Steps to Clean Your Vacuum Brush Roller

The vacuum brush roller rotates and vibrates against the floors and carpets you are cleaning. To keep it working well you should clean it regularly.

Step 1 – Switch off Your Machine
Never perform any maintenance work with the vacuum cleaner plugged in and switched on.

Step 2 – Remove the Base Plate
Remove or open the base plate of the machine. This plate will be held by twist catches or screws and will either be removed altogether or be hinged so that it can swing out of the way.

Step 3 – Remove the Brush Roller
The brush roller will be held in place by two levers that will swing through 90-degrees or more. The brush roller will simply slide out of its housing bringing with it the drive belt. Slide the drive belt off the roller brush and check it for wear and tear.

Step 4 – Clean the Brushes
The brushes that are angled around the brush roller need to be cleaned. This is best done by using the pointed end of a pair of scissors or a knitting needle to remove as much of the dirt and fibers as possible.

Step 5 – Replace the Brushes
The brushes on the brush roller can wear out and may need replacing. The brushes fit into specially shaped slots in the roller and can be simply slid out when the bearings have been removed.

Step 6 – Clean the Bearings
The bearings of the roller can be unscrewed by holding the bearing at one end and turning the bearing at the other. Often an accumulation of long hairs get caught around the axle through the bearings and makes it a little stiffer to operate. A drop of light machine oil will help lubricate the bearings.

Step 7 – Reassemble the Brush Roller
The bearings are replaced in the same way you removed them.

Hold one and turn the other. The bearings will fit in only one position with guides to set them in the right position.
The drive belt has to be positioned on the drive spindle which you will be able see behind the brush roller. It is easier to do this before you fit the brush roller into place.
Slide the brush roller under the drive belt.
You will know it is the right way around because a groove in the roller for the drive belt will be in line with the belt.
Replace the brush roller into the slots it came out of.
Step 8 – Clean the Base Plate
Often the spinning brush roller will fling material at the base plate where it can stick. This can build up into a sizeable deposit so it should be scraped away before you replace the base plate.

Vacuum cleaner
From Wikipedia, the free encyclopedia

A vacuum cleaner, also known as a sweeper, is a device that uses an air pump (a centrifugal fan in all but some of the very oldest models), to create a partial vacuum to suck up dust and dirt, usually from floors, and from other surfaces such as upholstery and draperies.

The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models—small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dust before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. Specialized shop vacuums can be used to suck up both dust and liquids.

Name
Although "vacuum cleaner" and the short form "vacuum" are neutral names, in some countries (UK, Ireland) "hoover" is used instead as a genericized trademark, and as a verb. The name comes from the Hoover Company, one of the first and more influential companies in the development of the device. The device is also sometimes called a "sweeper" although the same term also refers to a carpet sweeper, a similar invention.

History
The vacuum cleaner evolved from the carpet sweeper via manual vacuum cleaners. The first manual models, using bellows, were developed in the 1860s, and the first motorized designs appeared at the turn of the 20th century, with the first decade being the boom decade.

Modern configurations
A wide variety of technologies, designs, and configurations are available for both domestic and commercial cleaning jobs.

Technology
A vacuum's suction is caused by a difference in air pressure. A fan driven by an electric motor (often a universal motor) reduces the pressure inside the machine. Atmospheric pressure then pushes the air through the carpet and into the nozzle, and so the dust is literally pushed into the bag.

Tests have shown that vacuuming can kill 100% of young fleas and 96% of adult fleas.

Why Doesn’t My Vacuum Cleaner Work?

Since we service as well as sell at Shelby Vacuum, “Why doesn’t my vacuum work” is a question we hear a lot, followed by, “And what can I do about it?” Sometimes the answers are complicated. Other times, they’re pretty simple. On that side, here are some things you can do yourself to see check why your vacuum may not be working as you expect, and what you can do about them.

-It’s lost suction and is not picking up.
It could be that you have plenty of suction, but the brush is not working. Take off the brush and feel the end of the hose. If the suction seems right, the brush may need replacing, or it could have an obstruction that prevents it from turning (see below).

If, on the other hand, you take the tool off and you don’t feel adequate suction, the first thing to check is the dustbag. The more dust in a bag, the less suction, and the bag doesn’t have to be completely full to need changing. If you can see dust and dirt near the opening, it’s time to change it.

If the bag is OK, check the filters. They, too, can restrict airflow through the machine and reduce suction. A good rule of thumb is to replace your HEPA filters every year and other filters with every five bag changes.

Finally, check the hose. Remove any tools and detach it from the main body. Then drop a nickel in one end and see if it comes out the other. If it doesn’t, the problem is a clogged hose. If you can’t blow or shake out whatever is causing the clog, it’s time to give us a call.

-There’s no power.
If the vacuum is not doing anything, that is, there’s no power, stop. It could be that the vacuum cleaner is overheated and the automatic shutoff has kicked in. If that’s the case, wait a bit and try it again.

Otherwise, if it’s plugged in and not running, or it keeps shutting down, stop using it. Check the hose and see if it’s clogged. Otherwise, it’s probably an electrical problem that you won’t be able to diagnose or fix.

-The brush isn’t turning.
Brushrolls depend on a belt to transfer power from the motor to the brush. If the belt is slipping or broken, the brush won’t turn.

Sometimes, the brush shuts off it encounters unusual stress, such as getting the end of rug caught in it. If that’s the case, it just needs to be reset. Look for a small red button on the bottom of the vacuum that you can push to re-set the brush and get it moving again.

Sometimes fibers from rugs or even dental floss get tied up in the brush and stop it from moving. If it’s just wrapped around the brush, turn off the vacuum and pull or carefully cut the fibers with a single-edge razor blade or box cutter. Never use a knife. It might slip and cut you.

-My vacuum is making a strange noise.
With vacuums that us a fan to create suction, small objects can be sucked in and rattle against fan blades. In short order, the can break the fan, so if you hear a noise, turn off the vacuum immediately. Regardless, any noise that is unusual means there’s something wrong with the machine, and you should have it checked.

If you ever have any doubts about the reason why your vacuum cleaner is not working or if it is safe to use, stop using it. Never take a chance with any piece of machinery, especially if it’s plugged into the wall.
