How to Identify and Fix Common Vacuum Problems ?

Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked.
If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
If the Side Brush is not spinning after cleaning, you may need a replacement Side Brush Module. Please visit the iRobot Store – Parts and Accessories, contact iRobot Customer Care, or use an authorized retailer or partner.
Simply plug the product back in or restore the power and then switch off the appliance using the button on the control panel. The door will now unlock.
the vacuum system may be dirty, the pumping line may be restricted or too small in diameter, the pump may be dirty or with too little capacity, the pumping speed may be restricted due to other causes.
If there is something that has become caught in the hose in another part of the system, the airflow will be reduced and can cause overheating and a shut down. Clear out hoses, attachments, and brushes of any hair, dirt, and debris. This will allow for restored airflow and should get things going again.
Problems can occur when overused or clogged filters cause the vacuum motor to overheat. This not only shortens the motor life but causes a loss of suction. In some cases, total motor burn out can occur.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
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. The drive belt may need replacing; and the attachments, hoses, and filters may need unclogging.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
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.

Some vacuums have an in-line thermal fuse (often located between the switch lead and the motor coil). If the fuse is blown it will need to be replaced. – Check your home circuit breaker – it may have tripped. – Some vacuums have a brushroll on/off control.
The most common cause is water left in the machine. Try running a spin/drain cycle. If this fails, the machine can be drained by placing the washing machine drain hose lower than the drum (into a bucket or tray). The door interlock has simply jammed.
This could be due to a faulty pressure switch, which does not allow the cycle to reset to empty, so it cannot be released. You can try turning the power off and leaving the machine for about 10 minutes before turning it back on to see if the door unlocks.
“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.
Motor. Every vacuum has a heart, the part that keeps it running and this is the motor. Where is your vacuum cleaner`s motor located? It is the heavy part of your vacuum attached to a fan where air is forced over to expel the exhaust.
If your pump won`t start, the first place to look is the power source. Usually, the power isn`t properly connected, or the operating voltage doesn`t match the motor. Other potential issues include a malfunctioning motor, low oil temperature, pump oil that is too viscous or a clogged exhaust.
Overheating usually occurs because the dust bag has not been emptied, filter has not been cleaned or there is a blockage in the floor tool, wand or bent hand piece. If your vacuum shuts down unexpectedly, make sure you turn the vacuum off and unplug it from the wall socket.
To protect the cleaner from possible damage due to overheating a thermal cut out will switch off the electrical supply if the motor gets too warm. A blockage in the hose will restrict the airflow and cause overheating.
Overheating due to clogged exhaust filter

The exhaust filter can also get clogged, causing a problem with the motor cooling. Therefore, you should also check the exhaust filter if the vacuum cleaner smells burnt. It is usually located on the top or back of the unit, right where the exhaust air comes out.

Hoover Mach 5 turns off after 5 minutes of using. Can you advise the problem?
ANSWER : 5 minutes everytime? If so, raise brush all the way, and vacuum next to nothing. in fact, tilt vac up so the brush touches nothing. wait 5 minutes. If it doesn’t shut off, your brush is set too high. if it does, the motor is over heating. make sure bag is empty, no debris in brush, filters clean and make sure you’re not plugged into an outlet that a breaker on the outlet can pop too.

My hoover mach 5 stopped during use and will now not turn on
ANSWER : If the machine overheats, a breaker trips. Most breakers reset themselves after they cool off. You may have a manual reset button to push on your model. The machine will overheat if the bag is too full, or if the exhaust port is clogged. The reset switch is usually on the back of the motor housing, near the footswitch.

My Dyson DC07 will not turn on. I was just using it and moved to a new area and plugged it in and it turned on for a split second and then it turned off and now it won’t turn on at all. Any suggestions?
ANSWER : Loose wire, bad switch, or thermal cut-out. In any event, you will have to use a voltmeter to troubleshoot the problem, there is no way of knowing the problem otherwise
