Roller stops when the handle is lowered - Hoover UH70210 Bagless Upright Vacuum

If the roller brush of your Miele vacuum SEB 234/236 only spins when you manually hold down the switch, it indicates that there is a problem with the electronic circuit or mechanical parts responsible for engaging the brush. This could be caused by a faulty connection, a broken wire, or a malfunctioning switch. It's recommended to have the vacuum serviced by a professional to diagnose and fix the issue.

Check the instruction book. Some machines shut off when handle is locked in upright position.

Try these steps:

• Check the button that turns off the roller brush to make sure you didn't press it by accident.
• Unplug the vacuum and clear pet hair and other debris off the roller brush. It may stop as a safety feature if the roller brush is too restricted.
• Make sure the belt to the roller brush is placed correctly and not broken.
• Press the roller brush reset button. It may be located on the side of the vacuum's head, or inside the handle. The switch may need to be replaced if it's defective.
• The roller brush is disabled while the handle is in the upright position, so tilt the handle backwards while testing the roller brush.

I hope that helps you!

This vac has 2 belts. If both self propel and roller not spinning then most likely it is the wide flat belt broken or off. 4 screws on the bottom should gain you access to the belt area. another issue for this model series is a worn pulley on the roller, a new belt when inserted around the roller should be even with the top of the pulley groove.

with cleaner plugged in and turned on, push the little reset button on the side of the lower base of vac. Remember that the brush will not turn in the upright position. release your handle and you should be in business. hope this helps. please let us know. thanks renevacdoc

One of the common problems with the Savvy models is the upper handle switch. However if it is newer, you may also have an issue with the lower cable. To test it, turn on switch in carpet mode, and at the bottom rear, wiggle thr exposed black cable. if the roller starts and stops then it is bad and needs replacement. the cost of the part is about $10 but labor intensive to replace.

You need a new belt. Belts will stretch to the point that they won't turn the brush roll under load, they will just slip. Check the brush when you change the belt to make sure the ends turn easily, if not, then replace it also.

There are two belts on this machine. The first is a flat rubber belt that is designed to slip or break if the roller is jammed. This bet requires replacement at least once a year. It is vitally important to get the proper belt, as there is no other that will fit and function. The second is a v-belt and the early model belts were too thin and would sit down in the pulley too far and the tension required to drive the roller would be less than sufficient. When the handle is in the upright position, the roller stops. When the handle is lowered, there is an idler arm and pulley that sits down on the v-belt and tightens it enough to rotate the roller. In some cases, the tire on the pulley will come off and will not put enough force on the belt to tighten it.
There is also an adjustment on the hood of the machine to turn the roller off for bare floor cleaning. This adjustment should only be made with the handle in the upright position.
The belt(s) can look just fine and still be worn out. Replacing the belts is always the first solution and the least expensive.

The adjustment knob on the hood of the machine is a plastic "arm" that prevents the belt tensioner from tightening up the v-belt so that the roller will stop or start. If the knob is adjusted while the handle is back, it can break the plastic arm off and then the function will not work. This knob should only be adjusted with the handle in the upright position. Usually, if the arm is broken, the roller will still turn when the handle is lowered and will not turn off when the knob is selected to the bare floor. If the brush roll will not switch on , it is usually a problem with the belt(s). You should replace the belts yearly. They can look fine, but be worn out.

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.
