Having problems with your Hoover U6616-900 WindTunnel Bagless Upright Vacuum ?

Brush belt The brush belt is loose and the lever control does not do anything.


Answers :

I noticed the same thing myself. I had set the handle in the upright position, and laid the cleaner on the table to remove the rolloer brush. When I re-installed it I noticed the belt was really loose.

I checked several things before I finally lowered the handle to the operating position. This tightened the belt up, which makes sense when you stop and think about it. If you sit the handle upright to use an attachment you don't want the roller brush working away at your carpet when you don't need it.

Placing the handle upright disengages the roller brush by loosening the drive belt.

The brush roller stops turning and I can smell the belt burning, then it will catch and start working normal. I looked under the plate to check the belts and they looked okay and no hang ups of string or anything. The only thing that seemed weird was that the smaller belt that actually attaches and turns the roller is a bit loose. The larger belt is tight but looks like its the one that is burning and causing the smell.


Better to replace both belts the smaller one is stretched out thats whyits slipping ,be sure to clean the old rubber off the motor shaft before replacing the belts.it will cause the new belts to run unevevly and go bad before their time ...

The gear that turns the dual brushes on my Bissell Spot Lifter 1716 seems to be stripped. The belt looks loose as well, but when I take the belt cover and the brush assembly out, the gear that turns the brushes is loose and appears to be stripped on the cogs. When I turn the machine on the belt turns the gear but the brushes just sit there an vibrate. They make an attempt to turn now and then but not much. Need to get a schematic or the parts so I can order the gear if it is available and th

Hoover Wind Tunnel 7500 Brush not Turning. I have replaced the Brush and the belt. The problem does not seem to be either to me. I believe might be a missing part. The place were the belt hooks on is a metal pole which never seems to grip the belt well. In fact it seems loose most of the time and slips on the brush, causing the belt to eventually burn up. Could there be a missing plastic or rubber piece meant to hold the belt taught  on the metal pole?

For some reason, when I tried to put the floor vacuum attachment back on and vacuum the carpet, I realized that the belt was not engaging. the belt is in there and not broken, but it is not turning the beater brush. it is just hanging loose around the brush. When I turn the wheel to engage the brush, it picks the belt up, but when I attach the vacuum to the attachment, the brush is just not turning.

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

We have a Hoover upright vacuum cleaner, model Core 7. There is a switch that turns on and off the brush drive. This operates via a cam with a bearing putting pressure on the final drive belt to engage the brush head. My brush head is not turning and with the lever set to engage the drive there is still considerable slack in the final drive belt. There appears to be only a bearing deflecting the belt, should there be a pully or other device mounted on this bearing? There is so much slack a


Yes, there should have been a white plastic sprocket on top of the bearing - in its channel the belt would sit. Unfortunately no parts are available for this unit that can be bought retail - only available by order to dealer repair shops.\012\012\012 ... Hoover Vacuums

When I vacuum w/ the brush control in the on position it make a really loud noise, almost like a grinding sound. I have looked at it and nothing seems to be wrong, but I notice that the pin that engages the belt seems to vibrate a bit, possibly creating the noise. It started when I accidentally got part of a plastic grocery bag caught in the brush. Could it have stretched a belt? Nothing is caught any other place and it only makes the noise when the brush in in the on position.


Yes, the belt could have been stretched and is now vibrating and hitting other parts and creating a noise if much of the bag got caught under the belt. If you have another belt for this vacuum, please put it on and see if the noise stops. If it does ... Hoover U5780-900 Windtunnel Cyclonic Bagless UprightVacuum

The hose works great, but the head of the vaccuum does not pick up anything !!! I checked every opening that may have been clogged, but nothing came up. When I hold my hand under the brush/roller, it seems to be putting out more air than intaking air. Particles "dance" on the carpet, but don't get "sucked up" into the vaccuum ? I have had the vaccuum only 1 year, so the brushes should not be a problem. I changed the bag, and checked the belt. The belt and brushes seem to be OK. ?

My Hoover Windtunnel Mach 6.9 brush roller quit working. Upon investigating I found that the idler arm pulley was broken so I managed to replace that. Before putting the cover back on I see the control knob for the roller brush moves a plastic piece left or right to activate/deactivate the brush roller. I don't know where this plastic piece connects. It appears to me that the idler are when raised creates tension on the belt which drives the roller. I'm at a loss trying to figure ou

How to disassemble the brush to empty anything that might be stuck inside of the brush? The motor seems to be overheating, all belts have been checked, all airways are clear and the filter is clean. The vacuum is vibrating and releasing a burning smell, but still sucking up dirt. There is nothing stuck on the outside of the brush, but is there a way to check inside of it to see if that is where a clog is occuring?


If there's a burning smell and the belts are fine, the problem is going to be hot wires causing the insulation to melt, or the motor going bad. Discontinue use and have it checked at a repair shop. ... Bissell 6594 PowerForce Bagless Upright Vacuum
