How to Identify and Fix Common Vacuum Problems ?

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.
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.
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.
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.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
According to a consumer report survey, the medium lifespan for a vacuum is 8 years. With our tips on caring for your machine, yours should last much longer.
There`s no specific Henry hoover change-bag schedule you need to stick to. Just change the bag when it`s nearly full. If the suction is dropping and Henry`s having more trouble hoovering up messes than usual, it`s probably time to change the bag.
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.
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 most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
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.

Overheating may be caused from any accidental fault of the circuit (such as short-circuit or spark-gap), or may be caused from a wrong design or manufacture (such as the lack of a proper heat dissipation system). Due to accumulation of heat, the system reaches an equilibrium of heat accumulation vs.
As a general rule, if the repair is going to cost less than half the cost of a new vacuum cleaner, it`s best to go ahead and get it repaired. When the service tops half the price of a new machine, it`s probably best to invest in a newer model.
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.
Home experts recommend that carpets and rugs be vacuumed at least twice a week, and more often in high-traffic areas. If pets are in the home, daily vacuum cleaning is strongly recommended to remove dirt, hair, dander, and the smaller microscopic allergens that are invisible to the naked eye.
Designed and built in Britain, the quirky vacuums have a reputation for ease of use, effectiveness and durability, with many still going strong after decades of faithful sweeping. That`s no surprise: according to manufacturer Numatic, every Henry is “designed, tested and engineered to last a whopping 25 years”.
Due to new European laws concerning the power consumption of consumer appliances, Numatic saw fit to alter the power of the latest Henry vacuum models. Today, all Henry vacuum cleaners come with a standard 620W motor, instead of the more powerful version that was in the older machines.
Henry`s face was invented to help keep cleaning staff company. It is believed that when Chris Duncan developed the Henry vacuum cleaner in 1970– the same man who runs the company today, he did so with the intention to prevent late night and early morning cleaning workers from feeling lonely.
Lightweight and powerful, the Henry Hard Floor Cleaning Tool delivers peak suction performance on laminate, tiles and wood. Make easy work of hard floors.
A dirty or dusty Henry Hoover Filter can not only dramatically decrease suction, but they can harbour bad smells too. We recommend to replace your Henry filter at least every 12 months depending upon the amount of use. In between new filters you can clean your Henry filter to remove the dust and increase suction.
First, test the power switch for continuity to ensure that the motor is getting power. If the power switch has continuity, ensure that the blower wheel turns freely and is clear of obstructions. If power is getting to the motor, and the motor turns freely, but the motor still won`t run, replace the fan motor.
Overheated Motor

If your vacuum was working fine and then suddenly shut off, it may have overheated. Most vacuums are equipped with a thermal protector safety switch that won`t allow the motor to run when it becomes overheated. You will need to wait for 30 minutes to 2 hours, depending on your machine, to try again.

If your Shark ION Robot R75 vacuum stops moving unexpectedly after a few minutes of normal movement, it may simply have low battery power. Check that the device is powered on and that the battery has a significant charge.
We think you should get at least four years of normal use from a stick vac (using it twice a week) before its battery capacity falls below 65% to 70%. If you don`t, contact the retailer and ask for a fix. However, you shouldn`t expect to get a whole new vac.

Kirby Vacuum Hi Bruce, In my opinion, yes the Kirby would be worth it, as long as you are not replacing the motor. The switch would be the most expensive part besides the motor that would need to be replaced. The switch costs USD 49.99, the cord is roughly $39.99, and the carbon brushes are $29.99. I can easily walk you through any of these repairs should you need help. Kirby’s are great vacuum cleaners, that usually last 30+ years. Brand new these machines sell in the US for $1600 or more,

Hello, I have a Hoover quadraflex Powermatic central vacuum system Model # s8099-031 that requires a new replacement 35 ft hose…I have contacted Hoover and they do not know where to buy a replacement hose for this model. I live in Canada. Any idea where I can get a replacement hose for this system? Thanks kindly, Tammy
ANSWER : Tammy, no info re your location, so I”l try this.
Your Hoover hose is shot because it was made of rubber.There are new swivel handled, tangle proof lighter hoses made of vinyl which will last much longer and can be adapted to the old Hoover head by changing the upper steel tube.
Find a Hoover service center, outlet in the yellow pages and ask for the “NEW “style, gray“Plastiflex“ brand hose and upper adapter tube sold with new Hoovers at Costco and you will be all set. Then, when the head eventually dies, you can upgrade to a far better one , while still having the Hoover cannister, the hose and tools do not need to match the original tank.

My older Dyson DC14 (the purple one) early model with a clutch on the beater bar belt needs a clutch replacement. The bar has been cleaned and there are no worn or damaged parts so I conclude that the clutch at the motor end of the belt needs to be replaced. I can find the part online but no instructions on how to disassemble the vacuum to get to and replace it. Dysons only advice is to give me the address and phone of the nearest service center. Can you help me?
ANSWER : Have a look at www.dysonmedic.com which has some very useful info on dismantling and repairing Dysons.
.
.Although this site doesnt actually cover the DC14 yet, the DC14 is very similar to the DC07 so as regards dissassembling the machine, and replacing the clutch, my experience is that the DC07 info will enable you to do the job.

My vax power 8, 2200 watts 300 air watts 4L capacity upright Hoover is brand new, I emptied out the dust/dirt collecter and cleaned the motor filter yesterday for the first time, i switched it on and all fine, the brush is spinning and the hose is sucking, put the Hoover to work it’s fine for about 30 seconds then then suction stops and its dead it won’t collect no more, so switched off taken apart again and the motor filter is blocked and full of dust, so I unblocked it, do the same process aga
ANSWER : I had the same problem. It looks like the seal on the lid on the bottom of the cylinder has fallen out when it was emptied. There is no longer a proper vacuum being created so you don’t get the cyclone effect and the dirt doesn’t collect where its supposed to. it just clogs up the filter. I put sellotape to seal the lid and it works fine.
