How to Identify and Fix Common Vacuum Problems ?

Blockage – when a vacuum cleaner becomes unusually loud, it is normally because of a blockage of some sort. This is a problem that is easily solved by turning off the cleaner, check for blockages in the pipes, and remove them. You can also check and empty the canister to remove any possible blockages there as well.
If the cleaner becomes noisy or starts vibrating, it may be because some debris has got tangled around the brush roll or agitator situated in the bottom of the cleaner.
What should I do? If your vacuum cleaner whistles, this is usually a sign that your device can`t suck in sufficient air. Often, it`s the dust container or bag that`s full. Check these first and exchange them if necessary.
To reset the Brush bar press the Brush bar control button twice or switch the machine off and back on.
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.
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.
Check the LED light to determine the battery level. A solid blue light indicates that the machine is in normal operating mode. A flashing blue light indicates that there is no power, and the battery needs to be charged for a minimum of 3.5 hours.
If your Dyson is making a high pitched noise or is cutting out, make sure the dirt bin is empty and there are no blockages at the top part of the bin. You can use a flashlight to look for other blockages while checking the valve at the top of the wand where it attaches to the canister.
Low battery level
It sounds simple but a dead battery is the most common cause of the vacuum powering down while in use. Charge the vacuum battery for a minimum of 2 hours. After the battery is fully charged, power on the device.
Sound enclosures, noise reduction blankets, sound curtain noise barriers, or sound barrier walls are a few options to consider when reviewing noise reduction materials. If the vacuum pump is indoors, a noise enclosure would be the recommended solution.
During the propagation of sound, the particles of the medium receive these vibrations and transfer them to the surrounding particles, allowing sound to travel. So what does happen to Sound in a Vacuum? In a vacuum, there are no (or very few) particles that can transfer and carry vibrations, so the sound cannot travel.
A high pitch whistle could indicate a seal is damaged or the machine is blocked. If the noise occurs without the Wand and Cleaner head, it is likely to be caused by either the bin or cyclone.
If the noise is intrusive, switching the machine off at the wall will stop the noise, or altering the position of the product in the room might make the noise less audible.
If you use a Dyson cordless vacuum cleaner, you`ll probably be familiar with a sort of “boing” sound whenever you stop cleaning as the motor winds down. But did you know that the “boing” sound is intentional and designed to give the device a bit of character? Don`t worry, we didn`t either.
That`s nothing to worry about. The whooping noise is air coming between the post motor filter and it`s seals.
Roomba Discovery Roomba is fully charged and cleaned with sensor wiped clean. When turned on it it sounds normal and commences to go, but it then acts like it is putting on the breaks, spins, tries to go and manages a short distance and breaks again, just not making any progress because it keeps breaking after a foot or so and turns and tries again. Sometimes is gets so stuck from moving forward at all, like it is stuck in one spot just trying to go while seemingly surrounded by barriers. Somet
I had the same back-up, turn, move forward a couple inches, backup-up, etc. problem. Try cleaning/cutting the hair, etc. out from around the brushes, as well as around the ends of the brushes. Also, try a Q-tip to clean out the four pair of sensors (on my Roomba there are four pairs of little lenses under the bottom of the bumper) that (apparently) can cause the Roomba to think it is going over a cliff so it backs up. I didn’t have a can of compressed air, so I turned it over on the grass and went after it with a leaf blower..up close. Lots of dust came out and it has worked fine since.
