Question about Hoover F5886-900 Steam Vacuum

1 Answer

High pitched noise

I hadn't run my Hoover F5866900 for some time, it was stored inside the house though and when I went to turn it on, all it does is make this high-pitched noise. It has never done this before. Any suggestions? Thanks for your time.

    i had that problem and posted a solotion to it its not your motor bearing, if it was there will be a huge vibration throughout the entire vac. You have a problem with the round plastic device that the tools plug into on the left side its a turbo charger of sorts that the solution runs into and gets pressurized by an impeller that is in the flow of the suction and drives a fan like impeller [quite small] mounted on its shaft end, it is in the water dispensing flow path. This is not a well made device for the rpms its turning so failure is enevitable, poor alignment or as in my case foreign object gets inside the air impeller to cause mis alignment or small warpage of the all plastic housing and assembly. I saw no bearings just a brass bushing on one end of the entire assembly with nothing keeping it from moving slightly in or out, of course this is critical for perfect balance and proper clearance to work at high rpms. I took mine apart and cleaned it out calcium will destroy any steam cleaner made . I would suggest running a cup full of clr or = and after the solution starts to come out of jets turn it off and let it sit for a while to dissolve the buildup then run it through then flush the system with a coupla tanks of water, do thjis outside of in a bathtub, I'm sure it will quiet it down and restore the flow of solution. The motors on these vacs are bulletproof and the bearings are big and strong anlomg with the main drive saft I think it was at least 3/8" thick and the impeller it drives is aluminum so even if it takes a jolt the blade will bend way b4 the shaft will ever.

It sounds like you may have a bearing problem. The motor bearing eventually gets damaged by the water vapor that is drawn in by the fan. This will cause a high pitch squeel from the motor. It is possible to replace the bearing, but it should be addressed by a professional techician.

My vax vacuum has started making a high-pitched whining/whisting noise

Ususally this is caused by a forein object has gotten hung in the suction impeller attached to the motor. the noise flucuates due to the housing flexes with the movement of the handle and rod. the housings are usually made of plastic and something very small can easily get stuck in it and stay for a very long time. The vacuum needs disassembled and the forien object removed from the fan housing...

I have a Hoover Hurricane HU4207 2000w. The electric cable has become disconnected inside the hoover. How do I get to it. I have removed the cover housing for the handle pipe. Then all visible screws on...

You have to remove all the screws to uncover the system. After that only you can get to the bottom of the housing. There you will see the entry of the power cable.

There are sparks coming out of the motor housing. It is making a high pitched whine.

I'm sorry to tell you that the motor is more than likely done.

Generally you will have a burning smell associated with the sparks and whining. You can source a motor at your nearest hoover dealer, but depending on the age of the machine, you may just want to consider a new one. It is hard to say.

Brushes don't spin

Hello :
try this please : switch the carpet/bare floor dial back & forth 5 times, ending on carpet. Tilt the handle back as if to vacuum upright & lay the vacuum on its side so it is resting on the side opposite the carpet/bare floor dial. Turn the vacuum on.
or try this also if the above suggestion didn't work :
Maybe the belt is broke. You will have to replace the belt before the roller can spin. You must have run over something in the carpeting like string or whatever to have it break. Happens all the time. Get several replacement belts to keep as spares while you're at it as nothing is worse then having to vacuum and no spare belts.
please rate !

I have two older Filter Queen (brown vacuum cleaners). Besides unclogging the hose area and making sure it is not filled with dirt, what else would cause the machine to run hot and have a high pitched...

High pitched sound is often caused by air leaks in air ducts. This will also cause hoover loosing sucking power and slightly overheating.

If the hoover is overheating a lot, then noise can also come from the motor. In that case the part must be rplaced.

Try replacing the cone filter, the secondary filter, and the insulation at the top of the machine.
If that does not fix the problem, then the hoover must be taken apart to clean or repair the air duct.
