How to Identify and Fix Common Vacuum Problems ?

The Dyson V11`s vacuum motor is also more powerful, delivering 185 Air Watts of suction power in Boost mode, up from the V10`s 151 Air Watts of power in Max mode. With more power at the vacuum`s head and in the motor, you might think battery life would take a serious hit.
Developed by a team of 370 engineers globally, these latest vacuums use a Dyson Hyperdymium motor which generates up to 230 air watts of suction[1] and 5-stage filtration captures 99.99% of dust particles down to 0.3 microns[2] for a powerful deep clean.
Dyson Cinetic™ science

36 cyclones accelerate air to 180mph, generating over 100,000 g-force to fling microscopic particles out of the airflow. The Dyson Cinetic™ tips oscillate at up to 5000Hz, so the tiny particles can`t clog them, and the vacuum maintains constant, powerful suction.

Within the 3.5kg machine is 262AW suction power1, to ensure no loss of suction. HEPA filtration traps 99.99% of particles down to 0.1 microns in size2, for scientific proof of a deep clean. Our latest vacuum also includes a single-button power control – removing the need to hold a trigger as you clean.
Producing up to 115 Air Watts, it generates powerful suction on carpets and hard floors.
These are the vacuum pressure ranges as measured in Torr (or fractions of 1 Torr). What defines a high vacuum is then that it is normally placed in the range between 1×10–3 to 1×10–9 Torr, equaling one thousandth (0.001) of a Torr (or 1 micron) down to one billionth (0.000000001) of a Torr.
Suction Power

This is an indication of how good the vacuum cleaner is to clean – i.e. the work to be done. The suction power is measured in Watt (W) and is typically between 250 W and 450 W for machines with 1 motor.

A clog is a common (perhaps the most common) reason that a Dyson unit loses suction. They have a number of choke points in the airflow paths. Some considerations follow: Hoses: because of their often rough inner surfaces and inevitable bends, hoses are prime locations for clogs.
Which Dyson vacuum is the most powerful? In terms of sheer suction power, the Dyson Ball Animal 3 Extra is the most powerful option in Dyson`s current lineup, offering 290 AW, or air watts, of suction power. Among the brand`s cordless stick vacuums, the Dyson V15 Detect is the most powerful, with a rating of 230 AW.
Dyson invested £2.5 billion in research and development.

While you might feel that this is the reason their products are expensive, you`re highly mistaken. This investment was mainly to accommodate a centre for their 1,200 employees, 22 laboratories, prototyping space, and areas for collaborative work.

I`m sorry to read that you`ve had trouble placing an order for spare parts for the V11 Outsize vacuum. While stock levels do fluctuate throughout the year, depending on demand which can be higher around our peak periods and gifting seasons, I can reassure you that this model has not been discontinued or retired.
Although the V10 has a frighteningly powerful motor, the V11 motor is still about 20% more powerful according to Dyson. The V11`s High Torque cleaner head accessory has taken the cordless vacuum market by storm in its flagship status and dazzling cleaning performance.
The basic formula F=PxA is used to calculate the force of the suction cup with: F is holding force (or the vacuum force of the suction cup) P is pressure. A is is the contact area (the size of the suction cup surface)

Loss of suction in dyson dc08 – Dyson DC08 Cylinder Bagless Canister Cyclonic Vacuum
ANSWER : Hi there,

If your DC08 doesn’t seem to be picking up as well as usual, there may be a blockage in the machine. The filter may also need a wash.

The easiest way to locate and remove any blockages is to follow the steps shown in our online support guide:

http://support.dyson.co.uk/support/dc08/dc08-standard/my-machine-is-not-working/machine-not-sucking-picking-up-as-well-as-usual/check-the-floor-tool

In normal use, the filter needs to be washed at least once every 3-6 months, as shown in the video below. Use cold water without detergent, and allow at least 12 hours for the filter to dry completely before replacing it.

This should resolve the issue, but if you’d like any further assistance or advice, please call us on 0800 298 0298. Our Helpline is available from 7am until 10pm, 7 days a week.

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

I had the vacuum cleaner question about the canister and the wand/powerhead… the Kenmore Progressive Vacuum canister model 116.25812 and the canister not powering off without unplugging the vacuum. The solution I received that they both run on their own switch so it is normal makes sense. However, is there a power switch on the canister anywhere? The only way for the canister to be turned off is by unplugging it. Any ideas? One would think there would be a switch. I am new to fixya and hope
ANSWER : Hi. On some models, one switch controls all of the power. Your issue, which is no working switch is almost certainly a blown triac on the circuit board in the canister – kenmore part number KC86WBZRZ000

Looks like a common fault with this particular model judging by the number of complaints on the web.

.Take it to your local vacuum repair shop and they should be able to fix it for a nominal fee.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.
