Most cases of a jammed or stuck brush bar are quick and easy to fix, simply pulling the debris gently from the brush bar. Alternatively, if you need to clear a problematic blockage, you can take the brush bar out of the housing easily, for quick maintenance.
Brush Head Bearings Are Clogged or Have Failed These are symptoms of bad or dirty bearings. You should remove the brush roll or rolls from the vacuum. Check to see that the bearings at the end of the brush roll allow it to spin freely. Make sure that there is no hair trapped in the bearings.
The brush roll or its bearings may be clogged with hair, threads or dirt. Make sure they are clean and the roll spins. The belt may also have slipped because it was loose. Check the fit of the new belt when it is installed.
To reset the Brush bar press the Brush bar control button twice or switch the machine off and back on. Please note: In normal use, the Brush bar automatically turns off when the machine is upright and automatically turns on when the machine is in the vacuuming position.

Inspecting the Vacuum Commutator for Motor Brush Problems
Test that by turning the motor off and pushing on the center shaft, the armature. If it has any play, besides spinning, then replace the motor. If solid then replace the brushes – motor brush replacement instructions.
Clear the brush roll of any hair and debris and inspect by placing it on its end and spin. The brush should spin freely. If it doesn`t spin; it may be time to replace.
If your brush is scratching your floor, or not cleaning as well as it used to, then you may want to replace your brush bar.
Description. This genuine Dyson vacuum part is the reset switch for the Dyson DC24 and D25 uprights. This switch needs to be activated if you experience a power surge while vacuuming, and your vacuum turns off as a result.
To fix a clog in the hose, feed one end into a garbage bag, and poke the other end with the back of a mop pole, until you push the clog material out into the garbage bag. To fix a clog in the vacuum, whether it is a canister or bag, use your finger to feel for a clog. Pull as much of it out as you can and discard.
The DC14 was released in 2004. It is a revision of the DC07 upright vacuum cleaner with lower centre of gravity and `telescope reach`. It uses Dyson`s Root 8 Cyclone technology, which maintains constant suction.
Most problems arise because of a blockage – if not a dirty filter or cyclone unit, then something could be caught in the wand or the brush bar. Once again, the lack of suction could be caused by a dirty filter or a blockage somewhere in the vacuum`s system.
The rotary brush in the cleaner head of your Dyson V7 spins at high speeds and helps to beat and dislodge the dirt out of your carpets.
If your vacuum cleaner had a strong acrid burning smell before it lost power then the chances are the motor has failed which will require a motor replacement.
Even with the powerful suction for which the Dyson brand is known, the Dyson vacuum can get clogged. If this happens, you can easily remove the clog and get back to vacuuming quickly.
Many universal motor malfunctions are caused by wearing down of the carbon brushes, the soft blocks of carbon that complete the electrical contact to the motor`s commutator. When these brushes become worn, the motor will spark, and electrical contact may be incomplete.
Brushes. According to iRobot, brushes should be replaced every 6-12 months. Robot vacuums like the iRobot Roomba j7+ have multiple brushes that allow it to clean.
The typical life expectancy of vacuum motor brushes is around 800 to 900 hours of use; the bearings or the armature usually fails shortly after.
Roller brush is not spinning
Check to make sure the vacuum is switched to the correct mode. The switch should be in the Power and Brushroll mode to make the roller spin. If it is in just the power mode the roller will not move. The brushroll indicator light should be green when working.
If you checked your brush roll, floor setting, and belt but your brush roll is still not spinning, that means you probably need a Shark micro switch replacement. This small switch tells the vacuums brush when to start spinning.

Now that I just fixed my Lux Legacy canister vacuum, I need help on my other Electrolux Regency Series upright! The vacuum works fine but the rotating brush does not work and the brush motor does not turn on. Tried cleaning the brush and hitting hte reset button to no avail. This upright has a triple setting switch and I checked the each of the wires seem to be attached. Tried rotating the brush by hand and it would not budge. Was going to “encourage” the brush to turn with a set of articula
ANSWER : There are a couple rectangular holes on the bottom of the power nozzle, beside the wheels. These have tabs in them that need released with a standard screwdriver.
.

.Once they release, turn the vacuum over and lift cover of power nozzle at the back. This pulls the front of the cover out of the lip on the “bumper”.
.Once this is done, you’ll need to unscrew the screw at each end of the brush. Lift the brush out and thoroughly clean it, including the ends.
.

.
.Check the wiring to make sure they’re connected to the terminals of the motor. Also, check the belt for wear and tear. These belts can last for five years or more, but if it looks bad a good time to replace it is while you have the power head apart.
.When reassembling the vacuum, ensure the belt is fitted properly around the motor shaft and brush.
.Insert the front of the cover first, ensuring the edge fits neatly beneath the lip on the bumper all the way around. It takes a little manipulating to press the back into place. Make sure both tabs click into the locked position. Turn the vacuum over and reinstall screws. Try to rotate brush by hand a few times.
.At this point, plug the vacuum in and turn it on. If the power head doesn’t run, press the reset button. If the power head motor still doesn’t run, it could be due to loose or disconnected wires that lead to the reset switch, a bad reset switch, or even a bad motor. The vacuum needs to be taken to the nearest Aerus Electrolux store for further diagnosis and repair.
