Bissell proheat turbo 2x upright cleaner -how do I reassmeble?
Yeah, it’s annoying that the manual doesn’t give more detailed instructions and drawings to help with this, because you do have to take the roller assembly apart sometimes to clean built-up carpet lint off the unit properly. If you don’t do this, I’d expect you’d have more problems.
I have a different model number Bissell Proheat than yours. Yours may have different parts or go together differently than mine, but I'll tell you how I do it on mine and you can try my way out and see if it helps you.
(In all cases where I use left vs. right or front vs. back, as when these terms are used with a car, I am facing the front of the Bissell. I am NOT behind the Bissell, where I would stand when cleaning carpet with it.)
Here's how I put it together. This takes much longer to describe than to do, once you figure out where everything goes and you get the hang of doing it!
Attach the left arm with the two silver rods (ONLY attach the left arm here-- leave the corresponding right arm, which looks like the left arm except it has no silver rods, off the bottom unit of the Bissell, for now) to the left side of the Bissell, with a silver screw with a built-in washer. The screw hole is on the back end of the arm and the arm dips down towards the front of the Bissell and holds the two brushes in position so that they can turn without striking the top of the underside of the Bissell or dragging on the floor.
Put a small silver washer on each long, silver metal post, where the roller brushes will go, and slide it all the way to the left.
Put the larger rubber belt around both metal posts, about halfway to two-thirds of the way down the metal posts.
Slide the brushes halfway down the metal posts and attach the larger rubber belt to the cog wheel on the left side of each roller brush. Then slide both roller brushes with the large rubber belt attached all the way to the left so that the cog wheels are against the inside of the left arm. As you move the roller brushes almost all the way to the left, you may be blocked from reaching the end until you carefully work the rubber belt around a plastic flange on the inside of the left arm, but do this and be sure the roller brushes are up against the inside of the left arm. Make sure the rubber belt is still on each of the cog wheels when the roller brushes are pushed all the way left. If you turn one roller brush, the other should turn, too, because of the belt attached to both cog wheels.
Put the small belt around the small cog wheel on the bottom unit of the Bissell behind the right end of the back roller brush, and also around the cog wheel on the right end of the back roller brush. (The right cog wheel on the front roller brush is the only one of five cog wheels without a belt, when everything is assembled correctly.)
Put a small silver washer on the right end of the silver rod passing through the back roller brush.
NOW attach the right arm, using a silver screw with a washer, to the middle screw hole on the right side of the bottom unit of the Bissell. The right arm should mirror the left arm, so that the two arms hold both roller brushes in position on the right side and straight across the bottom unit of the Bissell. It is normal for the roller brushes and arms to be able to flex up and down a bit, when everything is put together correctly. The built-in washers on the silver screws which attach the arms keep the arms and roller brushes in the generally correct position but allow them to flex.
Now using your fingers you should be able to slowly spin the roller brushes without the brushes contacting the top of the bottom unit of the Bissell and without dragging too low against the floor. Check one more time and be sure the belts are positioned correctly around four of the five cog wheels.
If everything seems right, attach the two side covers. These are not interchangeable; the left cover only fits on the left. The short black screw goes in the back screw hole, and the long black screw goes in front.
Then attach the front cover. It's important to be careful that the hooks on the front cover are inside the side cover holes designed to hold the hooks before trying to tighten the last screw through the tab on top of the front cover. If you aren't careful about this, it's easy for the front cover to be out of position or to break its tab.
Try powering up the Bissell and see if the rollers spin correctly. Remember that the handle must not be locked upright and the trigger must be depressed with the Bissell turned on before the roller brushes will spin. (Sometimes people complain that nothing happens with the unit turned on and the trigger depressed when the only problem is that the handle is in the locked upright position.)
