Question about Bissell 3750 Lift Off Bagless Upright Vacuum

1 Answer

I unscrewed the roller brush protective cover and removed the brush to clean it. Now the roller won't turn because the drive shaft is not turning. Is there a reset button or something?

I looked at the pictorial of this vacuum at this URL: http://middleeasten.bissell.com/images/UserGuides/3750.pdf
This shows the belt to slide on the motor drive pulley and also on the brush. If the brush is bound up on the two ends where it fits into the body of the vacuum, you would have a problem turning it. Please be sure the end pieces are clean and if possible, spray with a little bit of WD40. Replace the brush and belt according to the picture in the URL and it should work fine. Please contact me if you have questions or experience more problems. Paul

Help on changing belt on shark rocket HV300


Hello, this is Ava with Think Crucial.

To change the belt of your Shark vacuum, you will need a flat head or a philips screw driver and a pair of scissors or a knife to clean your roller brush.

First, make sure to switch off your vacuum and is unplug from the power. In an upright position (vacuum), remove, empty and clean the dust cup. After cleaning the dust cup, lay down the vacuum horizontally on the floor to access the brush roller unit.

Using the appropriate screewdriver, flathead or philips (which will depend on the model of your vacuum), unscrew that holds the roller cover in place. When you lift the cover of the roller up and if it doesn't lift easily, don't force it because it probably means that you have missed one of the retaining screws. After you removed the cover, you will be able to see the roller assembly and the belt that drives it. If the belt has become worn, lost some teeth, or it has broken completely, you will need to remove the roller itself to be able to replace the belt. Clasp the end of the roller that is farthest from the belt between your fingers and lift it out of its holder. It should lift out very easily. You will then be able to lift out the other side of the roller that is attached to the belt and slip the belt on it. The other end of the belt, if it has not broken completely, will be attached to the motor shaft. That too can now be slipped off the end of the shaft.

With the roller bursh having been removed from the motorised head, I suggest you clean it. You may use a pair of scissors or knife to cut/remove the hair that are stuck. Be careful that you don't cut the bristles of the brush. Also, remove any debris that has found its way inside the roller cover at this point by using a wet towel or tissue.

To replace the belt, slide the new belt around the drive shaft of the vacuum cleaner and onto the seat. Then, replace the belt end of the roller, sliding the belt around the roller inside the plastic guides that are there to stop the belt slipping. Clip the far side of the roller back into the slots provided for it and adjust the belt as necessary to make sure that it is sitting squarely on the roller and the drive shaft and then check that the belt is tensioned properly.

Now, all you need to do is to replace the brush roller cover and tighten it down with the screws that you removed earlier. When you tighten the screws, they should be firmly screwed on, but don't overtighten the screws or you could crack the plastic casing. You can then reconnect the shark vacuum to the power supply and check that everything is working properly.

We have based this guide on the manufacturer's own guidelines, so you should have no problem with your Shark vacuum if you follow these steps.

Brush not turnning


The brush roller is driven by a belt installed on the motor shaft. The belt could be broken or off the shaft. The brush roller could be clogged inside the end caps with debris which prevents rotation. To solve the debris problem, it will be necessary to remove the belt from the motor shaft, then note the orientation of the end caps and remove the brush roller. Next, remove one end cap and check for clogging material. Remove the material. Slide the brush roller shaft away from the end of the brush roller to check for clogging material at the opposite end. Remove the material. Slide the brush roller shaft back into position and reinstall the end cap. Reinstall the brush roller in the correct position. Reinstall the belt. Check for proper rotation of the brush roller.

Hoover mach 5 turns off after 10 minutes of use


I have had problems with the belts on my Mach 5 overheating (smell of burning rubber) and also with the motor overheating and shutting down.
I learned the hard way that one of the issues might be that the roller/brush on the bottom of the unit has a metal bearing inside the roller/brush that can become clogged with hair (both human and pet hair) which effects performance of the unit.
Another item to check is if your dust filter is not plugged up which is located behind the removable dirt cup. This is the cup that you remove that collects the dust/dirt/hair from your floor. Take the removable dirt cup out by depressing the gold button and then look behind where the dirt cup sits for filter. This can be cleaned out by washing it with soap and water in the sink but make sure you let it dry overnight before placing it back in the machine. This probably causes some of the overheating when not enough clean air is passing through the machine.
It’s fairly easy to fix.
Lay the vacuum on the floor so that you can see the roller/brush. Then remove the phillip head screws that hold the protective plastic plate over the roller/brush. (There are about 6 screws that hold this plastic protective plate in place) Also, you will be removing the (1) screw that also holds the plastic plate over the belts. There are (2) belts that you can remove and when in doubt replace these (2) belts for around $9.00.
Once you have the protective plastic plate off that covers the roller/brush disconnect the belt is around the roller. Take the roller and cut off any hair that is wrapped around the roller. Next, grab the roller by each end and twist the ends caps and (1) of the ends will unscrew. Once you have unscrewed one of the ends remove any hair or dust that is trapped under this cap. (Be careful not to lose the small metal washer that sit on top of the bearing)You will notice under this cap is a metal bearing that can become clogged and jammed with hair. The hair should come out fairly easy and allow the brush to spin fairly easy once you have screwed the end caps back in place test that it spins freely. If it doesn’t spin freely replace the roller/brush with a new one for about $23.00.
When you put the belts back on the thick rubber one (Belt # 40201-271) has probably become stretched and should be replaced for about $3.00. The small diameter belt that goes over the roller/brush probably does not usually need to be replaced and does not usually fit very tight. I have heard that people will take the small roller/brush belt and turn it upside down to get a better fit.
I just did this on my Mach 5 and it runs like a new machine. I did end up replacing the roller/brush head.
Hopefully you will find this useful.

Changing the belt


It is quite easy. Just take off the bottom of the vacuum encasing the roller brush. It should snap off or you may have to unscrew some screws and lift the cover off. Then remove the roller and clean it while you have it out. Now put the new belt on the motor shaft or pulley and slip the brush into the belt. Then replace the roller brush pulling the belt tight. Replace the cover and clean house.

Wish to remove bottom ofpowerhead-Kenmore Progressive 11629912990


I have a whispertone vacuum, different model #, but maybe instructions will be the same. Turns out I didn't need a new belt, just clean out the crud and reset overload protector. The instructions in the manual tell you to remove the light cover and bulb first. To do this, press in and lift both sides. Push in and turn bulb counterclockwise to remove. (you need to do this because the next step involves turning the unit over). This takes you to
Step 2. Unscrew the cover screws ( on either side of bulb).
Step 3. Turn unit over. To remove cover, insert screwdriver at cover tabs on both sides and twist to release tabs.
Step. 4 Turn unit right side up. Press handle release pedal and lower the swivel. Tilt cover forward from back until front snaps free.
Step 5. Carefully insert and twist screwdriver at each brush support to free brush from base.
Step 6. Remove worn belt.
Step 7. Slide brush supports off to check and clean brush support areas.

To replace belt: slide washers and brush supports onto brush assembly.
Install new belt over motor drive, then over brush sprocket.
Snap brush supports into place on base. Be sure brush supports are not upside down.
Line up front of cover and base. Rest cover on front edge of base. Tilt cover to back. Press cover firmly until side tabs snap into place. Replace cover screws, light bulb and light cover.

Most likely the brush motor is bad and not turning, part #2036757, would sell for around $23. To get to it, start taking out screws on the top cover, that motor is under the that top access cover.
