Dyson DC 14 hose has no suction, with or without brush attachments. Hot air shoots out from the base of the canister when I try to use the hose. I cleaned the top filter, but can't figure out how to remove the hepa filter to clean it without destroying the case. It looks like it might take three hands to insert pennies and "flip" the case open as is suggested on a youtube video for a different model. Would this even help, assuming I could get the thing open?

I am losing suction and it sounds as if there is a leak in the vacuum(I hear air rushing around). There is also a high pitched noise. Dyson dc07. Can there be leaks in the gaskets where you clean hoses and filter? are they replaceable. Does the noise suggest the bearings are going in the motor?Is it worth getting fixed?

It wont be a gasket problem - they don't tend to fail. \015\012\015\012A high-pitched noise can be a number of different things. That is too vague to diagnose on here with the description you have given. Can you be more specific? ... Dyson DC07 Bagless Upright Cyclonic Vacuum

My brushes on my hoover streamvac will not rotate. I removed and cleaned assuring that the filter was also cleaned. The only different thing I have done is to insert the upholstery attachment and removed it after use (didn't work so well) suction seemed weak. I am also noticing that there is air being blown out of sides where the dirty water container is. (don't recall that in the past).

Kenmore 21875 One day it's working fine. Next day, it won't turn on. When I attach the hose to another vacuum cleaner, it runs. Is there a reset button on the canister? Could it be the receptacle is bad? My Kenmore Progressive won't turn on today either -but was fine last week. I cleaned the filters checked for blocked air, tried a different outlet and no luck. I'll check the pins on the connections and see if one of them is not matching up or appears worn.

My Kenmore progressive vacuum is extremely loud. The airflow and suction seem to be uninhibited, but the noise is loud and frustrating. Should the filters just be cleaned or is this a sign of a different problem? It's a Kenmore Progressive Bagless Upright Vacuum 35912 and we've had it for about four years.

I put it on floor for my hardwood floors and picked up loose clean cat litter and went to put it back on carpet and it made a horrible noise like it was rubbing. cleaned the filter... cleaned the roller thingi ...checked the belt and it is still making that horrible noise. It does not make the noise when I have it on floor but as soon as I put it on carpet it screams at me. Help! Please and thanks Linda

Replacing filter Got a Filter Queen Majestic vacuum from my inlaws when they moved overseas. I am in middle of vacuuming, got a weird noise, so opted to check and clean the filter for first time. UGH. The lower 'pot' that's the bottom part of the thing was full of gunk, but the filter pristine clean against the cone that's attached to the upper part of the unit. In other words, I am shocked to see that the dirt goes not INTO the filter, but outside of it into the bottom portion (that I call the

I have a nearly 9 year old Electrolux Excellio Z5228 vacuum cleaner. It has recently started cutting out during operation. I cleaned the micro filter (between bag & motor) via brush & hitting against wall & seems / looks quite clean. I washed the gore filter (output from motor to clean the exhaust air) as per instructions, then let to dry. It was very clogged but now very clean. The vacuum clearner still cuts out often. Even after a long rest (say overnight) it still won't start, then ano

I removed the filter from the motor in the ball. After I cleaned it and let it dry, I put it back in. From then on, it makes a moaning noise when I turn it off after I vacuum. I followed directions to clean it and put it back (it's pretty straight forward and fool proof). I've since cleaned the filter a second time, doing the same steps and it seems to have made it worse.

My Bissell 3920 motor is making a high pitched noise. I have cleared out pet hair from top to bottom. Cleaned the lower filter and replaced the upper filter.

I cleaned out my dyson ball as it smelt when i hoovered, cleaned filters, washed out canister and took the screws out of the front bar so i could clean near the brushes.. now its making a high pitched noise and when i switch it off it makes a noise like an engine shutting down! Have i disturbed the motor?

Hi its Darran at Dyson. The screws on the base of the cleaner head should not have to be removed to access the brush bar so it is possible that the brush bar has come out of alignment, hence the noise the machnie is making. Pl ... Dyson Ball DC24 Bagless Upright Vacuum

We have the Kenmore progressive direct drive (bagless) and have had it for about 3 years. We have taken good care of it, and paid quite a bit for it hoping that it would last for a good long time. It has started making a noise that seems to be an overflow air type of noise coming out of a bottom air outlet opening for when the air flow is blocked. We have looked into clogs, changed filters, and the whole works, to no avail! Quite Frustrating since I love this purple vacuum! The machine started

Vacuum smells I have a 6 year old rainbow vacuum model E and it smells terrible everytime I use it. Probably because often times i don't remove the water basin after vacuuming and just let it sit. It's my own fault however now I don't know what to do to get rid of this terrible smell. I've water cleaned the hepa filter, not able to remove the separator screw to clean. Can you give me some suggestions?

Wondering if the head is plugged up because it makes a sound like air is escaping somewhere. I've replaced the original cloth bag with a comparable "O" paper bag from Sears. I tried to see if there was a clog in the hose by placing a broom handle in the hose to see if something would loosen. I also cleaned the filter and the air filter. If the head is plugged, how can I fix it? We can't get the vacuum apart. Thanks.

Why does my dyson slim dc18 keep shutting down, even though i keep it clean. Filters area is clean and all others have been properly blown out with air from a air compressor. It will work for about 5-10 minutes and then shuts down. Smells like ****, check the belt and a bit later it restarts again. It's seems to be almost over heating.

Maybe your motor is going. Here's a link to a site that talks about motor failure and replacement in a DC07 (not DC18).

Terrible noise My dyson was working great then started making this horrible noise. I cleaned the bar but noise is still there. I discovered the beater bar went around three passes then froze and started horrible noise again. my husband got the bar turning but after 2 swipes vacuuming it did it again. Can it be fixed or is it time to retire it and buy a new one. Wendy Kiser

That noise is the clutch. A very expensive part and very hard to replace. When a problem with the clutch happens it's generally not worth the time and money to replace.I suggest getting a different type of vacuum, maybe a Miele or Sebo. W ... Dyson DC07 Animal Bagless Upright Cyclonic Vacuum

My dyson d14 animal keeps cutting in and out. When it's on, the hole above where the filter is, keeps making a loud suction noise and it won't clean up hair and dirt.

Vacuum Cleaners require AIr-Flow. Your machine is not getting any air-flow. The noise you hear is a valve opening up to prevent your machine from overheating and burning out the motor. You probably have an obstruction somewhere in the machine. ... Dyson DC14 Animal Bagless Upright Cyclonic Vacuum
