My A 2045 Karcher vacuum's suction is really weak and the motor seems to be working VERY hard. The motor sounds like it used to when the vacuum fell over and went into overdrive! Now it's in overdrive all the time and the suction is minimal. Nothing is blocked and the filter is clean and dry. What do I need to do?

Have a Centralux Aerus about 5 years old. Don't see a model number. There is suction but beater brush quit working. Was using for a few minutes, shut it off for a few minutes, turned it back on and suction only. Tried the reset button also. Tried the sidekick attachment and it works fine. There was no smell like something was hot. Belt is fine. Are there any fuses or anything else to try? This vacuum cleaner has not really been used that much, it is hard to believe the motor would need replaced

There probably is a loose wire in the handle near the switch or a wire off near the swivel elbow near the vac power head. With the right fastener tool to remove some screws you can fix it yourself ... Electrolux Centralux Vacuum

I have an older Oreck XL vacuum that sounds like it is running twice as fast as it should. I disassembled the entire vacuum, including disconnecting the motor wires, to clean out the hair, string, and other things. When I put everything back and connected all the wires, everything appears to work, including the light. The only problem is, it sounds extremely loud like the motor is running too fast. The model number is: XL3610HH Ser. No. 3610HHXA039740-6 I do not have as electrical diagram to see

Dyson DC14 is not picking up as it should and the hose hardly has any suction. I have checked for blockages and there are none. When i turn it on it sounds like there is good suction then there is a second noise like the suction is escaping somewhere.

Dead motor? My 8 year old Miele S251i has worked fine, until I was recently vacuuming and moved the plug from one outlet to another. When I restarted the vacuum, it made rrrrr.....rrrrrr....rrrrr noises and smelled like something was burning. I turned it off, and it's shown no signs of life since. Sound like a motor problem? I've taken the cover off and looked at the cord and seen the motor, nothing looks obviously wrong, but I'm also not mechanical.

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.

I have a NUTONE central vac, when I turn on the power, It sounds like its grinding glass and doesnt suction. Could it be that broken glass got caught in the motor and all I need to do is clean it, or is this the sound of a failed motor?

More likely it's something in the fan. However, I suggest taking it to a vacuum repair shop to make sure. Something could have got into the fan system and is making a racket, but the motor itself won't crunch up glass. ... Electrolux Central Vacuum

The suction is good, but it can't pick up most of the stuff on the floor. The hand held hose works very well, but it doesn't even pick up little fuzzies reliably when I push it along. And, the suction is too hard I think because it used to push easily and now I have to push really hard, even on flat carpet.

Check entire length of hose, including the piece in the power head, for clogs. Simply drop a marble in one end and allow it to roll out the other. If it doesn't, then the hose is clogged somewhere. ... Dyson DCO7 Animal Bagless Upright Cyclonic Vacuum

Stopped working Was working fine then it smelled like burning rubber, not the belt I checked. It sounds like the motor wants to run then it just stopped but the light is on. What do you think, go by a new one?? This has been a great vacuum cleaner and I can not seem to find a Sharp anywere. Thanks for your time.

Well it could be the motor, if it is it would cost around $80 or so for a motor. May be better to buy new, thre are a number of good brands out there. ... Sharp Twin Energy EC-12TWT4 Bagged Upright Vacuum

I have a Rainbow E2 series, 23, for about 3 years. It has now a different and very aloud sound coming fron around the motor and also I feel it is not suctioning with the same power. If I close the hose like closing totally the suction entrance, the sound comes normally. I will appreciate if some one can tell me what to do, becouse there is not a Dealer in my Contry any more. Thank You. Pierre Chabaneix - Lima-Peru [email protected]

Hi there, Pierre!\015\012Sorry, but I think this is bad news. From your description, I suspect that a motor bearing has failed. The only way to fix it is to replace the motor, and without a dealer in your country, that could be a big problem.\015\012 ... Rainbow E series Canister Wet/Dry Vacuum

Motor still runs--sounds like jet engine. do I need a new motor? or is there some sort of muffler that has malfunctioned? vacuum belongs to disabled mom---so trying to do work ourselves--cant afford much. dont see anything obviously wrong--but know nothing about electric motors.

My Dyson animal seems to have an electrical issue that I am unable to pinpoint. Neither the wand nor the floor vac have any suction AT ALL. In fact the vac makes absolutely no sound and you wouldn't even know that it had power to it unless the rollers are turned on, the rollers work just fine. I had this problem start about a month ago and then it just started working again after messing with it for a while, now it has happened again and I am getting a little agitated!

Motor just makes 4 or 5 small clicking noises when you pull the trigger, then stops. The little lights illumintae around the "max" button as well. However, the motor does not engage in the slightest. There is no blockage at all. I have owned the vac for 10 months and know the sounds of blockage and clear them immediately. I just used it in the morning, plugged it back in and it has not worked since. Any ideas?

Miele S5000 (revolution 5000) vacuum cleaner - How do I open the casing? When the power button on the handle is pressed the green power-level lights on the handle light, but the motor sounds like it gives a little 'jump' but nothing more. The orange power light on the body also dims. I assume the motor or fan is jammed, but I can't open the body to find out. I've taken out to screws inside near either end of the handle, but to no apparent effect. I'm assuming the body is held together by plastic

WST 1600A I purchased this vaccum about four months ago from Heartland America. Up to this point it's worked fine. After cleaning it this time when I went to start vaccuming again it runa for about 10 seconds and cuts off. I've changed the battery, taken everything that can be removed out checked it and replaced it. THe motor sounds like it's straining. I have not taken the housing off the motor to see what's going on with that. I misplaced my manual.

It sounds like there is a clog. If there is no air flow it could be overheating. ... Westinghouse WST1600 Upright Vacuum

I have a Kenmore Elegance Vacuum with Dirt Sensor, Model # 116.30750400C, Serial number M41901532. When vacuuming the carpet the power head will work for 3-6 mins then automatically shut off, power is still there and lights work but the power head motor turns off and the suction stops.

Dyson DC07 works and cleans fine, but motor makes loud screaching sound.

If the screeching noise is happening at all times, it is most likely a motor failure; which unfortunately can only be resolved by complete replacement of the motor. \015\012If it's a loud ratchety-screeching type sound, and is only occurring wh ... Dyson DC07 Animal Bagless Upright Cyclonic Vacuum
