How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

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.
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.
If the machine will no longer efficiently pick items up, the filter might be dirty. If after cleaning the filter your vacuum is still not sucking things up, turn your vacuum around and pull the red tab at the bottom of your Dyson out.
Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
A Dyson vacuum cleaner has a lifespan of around 10 years. This is considerably longer than most other vacuums. So, if you`re looking for a high-quality vacuum cleaner that will last you for a long time, a Dyson could be a good choice. However, remember that Dyson vacuums are expensive.
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.
One of the first things to do when your Dyson vacuum cleaner keeps starting and stopping is to empty the bin. It may be full, or the machine may simply perceive it as too full to continue working. Dyson vacuum cleaners require constant airflow through them to work, and a full bin can stop this from happening.
Reset the machine without the app

The machine allows you to clear your WiFi settings, restoring the machine to the factory default. Press and hold the `Standby ON/OFF` button on the purifier for longer than 20 seconds.

Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

Boil old suction cups to revive them.

Take the pot off of heat and drop your suction cups in for about 30 seconds. Take them out with a pair of tongs and pat them dry on a lint-free towel. Try to use the suction cups right after you dry so they`re still warm and flexible.

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.
Give it a break

By letting the battery run down to empty at least once a month, you`ll help to prolong its life.

All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
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.
What is a Beater Bar? A beater bar is a smoothly contoured metal agitator bar on a rotating brush roller. See below image. It works in conjunction with bristle brushes to gently beat the fibers, when the beater bar rotates, to loosen soil and allow the brushes to comb away the soil into the suction ports of the vacuum.
It`s possible there`s a power consumption issue, with there just not being enough residual charge to run the machine. A new battery should fix this. My other thought is that it`s overheating. If too much power is pushed through the motor, which MAX power does, it could stop after a few seconds if it become hot.
Hold your brush bar under cold tap water and gently rub to remove any lint or dirt. Stand the brush bar upright and leave to dry completely. Make sure your brush bar is completely dry before refitting. The cleaner head housing is not washable and should only be wiped over with a damp lint-free cloth.
Wash filters in cold water only

(don`t use detergent or wash in a dishwasher or washing machine). Rinsing under the water supply then gently squeezing the water out of the filter. Repeat until the water runs clear.

Because there are so many different models of Dyson vacuums, there are many different filters. While most filters will need to be replaced every six months to a year, some are washable. These washable filters can be replaced less frequently and can be cleaned using hot water.
It may be full, or the machine may simply perceive it as too full to continue working. Dyson vacuum cleaners require constant airflow through them to work, and a full bin can stop this from happening. Make sure there`s no dirt lodged in the top part of the bin.

Dyson 18 slim the rotating brush bar will not rotate. Was working fine until I got the edge of a tablecloth caught in the brush, pulled it out ok but now the brush will not rotate fast, but will rotate by hand . Any ideas.
ANSWER : If the DC18 has a proteted belt then it will have to be replaced by a Dyson engineer or repairer. If the cleaner has a removable sole plate where the beater bar is then remove it and replace the belt – sounds like the belt has snapped and needs to be replaced. if your DC18 is still relatively new it should still be under guarantee.

I have a DC07 and the brush wasn’t rotating and I had no suction at the brush but perfect suction through the hose. I noticed a large build up of dog hair around the brush so I took off the cover plate and removed all the hair, cleaned inside the floor/brush housing and cleaned out the hose. I also cleaned the filter and removed the other air access cover and made sure that they were clear. I put everything back and the brush still doesn’t turn and there is still no suction through the bottom

The brush rotates on my dyson slim but there is no suction. though there is suction from the hose… has anyone any ideas????
ANSWER : Un-plug the machine first. Turn the unit over and remove the bottom plate. Check for and remove any debris in, around, or behind the beater bar assembly. While you’re in there, look at the beater bar ends where the bearings sit. and clean any debris, hair, etc, from those areas as well.

My model F5906-900 — problem is the brushes have stoped working… I pulled the brush assembly out by holding the two tabs, and all seems clean and the brush assembly rotates easly… onced the brush assembly is removed. What I did notice is the female driver slot (found in the main assembly unit) that drives the brushes seems stuck..Is that normal when the machine is not hooked up to power? How can I get the brushed going??? it is a good machine, but the brush options is important too it’s ab
ANSWER : (1) Assure the Brush Control on the hood is NOT set to the OFF position.
.(2) Remove the brush assembly by pulling/unlatching it from base on each side.
.(3) Does one of the brushes have the drive pin present? It should be about ¼ inch square, and two inches long. It attaches the brushes to the drive mechanism.
.(4) Remove and clean the intake filter. One the base of the cleaner, behind the brushes, squeeze the two red abs together and pull the panel down to access the screen. Clean the hair/debris off the screen and reassemble.

Poor Suction Heya! So I just picked up a used Dyson, but when I vacuum with it, the suction is pretty weak and it spits all kinds of stuff out the back and into my feet. When I pull the hose I have good suction, but in regular mode it hardly picks up anything. The brushes are spinning, and it eventually will clean an area if I go over it again and again. Maybe a clog somewhere? Please tell me that Dysons have better suction than my $50 Dirt Devil! Thanks!
ANSWER : I recently bought a second hand Dyson DC07. Its suction was poor. I removed all the un-clipable pipe bits and to remove any blockage but it all looked clear. The Final Sponge and hepper filter did have a lot of dust in it and the rotating brush was full of hair but nothing bad.
.
.I eventual gave in to curiosity and removed the three screws in the top or the yellow removable dust collection tube and cyclone bit to see what was in there. The mechanism to release the flap at the bottom of the collection tube does not allow you to remove the lid completely but it does open far enough to get inside. I found the whole top section of the yellow plastic bit blocked by a big plug of compacted dust and a champagne cork. If you are willing to take the risk and have a torx 15 screwdriver handy it that part may be blocked. It did get a bit messy.
.
.If I was going to attempt the same procedure I’d remove the dust collection unit from the vacuum cleaner as I did before, but leave the clear tube attached and the emptying flap firmly closed to reduce the mess from the dust falling out the bottom while cleaning the top part.

Noise My Dyson DC08 is making a loud, rough, vibration/noise that seems to be coming from the from the rotating brush housing. I replaced the old belt which was several years old and slipping. When I run the motor with the new belt removed the machine sounds normal. The bearings on the rotating brush seem to be running smoothly when turned by hand both when out of the brush holder and when installed in the machine. I can’t find anything rubbing on the belt or rotating brush. I applied a bit o

My dyson seems to have lost its suction therefore is not picking up anything yet i have found that when my dyson is standing upright it has a little more suction but nothing like how it use to work. This has only happend in the last 2 weeks. I sanded a floor & though the sander picked up majority of the dust i did use the dyson to pick up the excess and it is since then that my dyson has not been working to its full potential.

Lost suction my DCO7 lost suction in the hose I started taking it apart and cleaning it and looking for clogs (probably more than I should have) and when I put it back together it has awesome suction in the hose but no suction in the base. It just pulls the pine needles up (christmas tree) but they never appear in the “bag” compartment and when I look they are just all gathered in a clump in the bottom by the brush.
