Hoover Savvy self propulsion not working

I have the Hoover Savvy U8174-900. The on/off switch is acting up (hesitates) as if it is shorting out. Recently, the self-propulsion feature has stopped working. The carpet brush seems not to be turning as well.

    I have a similar problem. Except mine will not turn on at all now. Used to, I would play with the switch and I could get it to work. Not all now.

The switch contacts are burned out and the switch must be replaced. This link sells the whole handle with switch but, check your serial number to be sure to get the right one. If you can use a Philips head screwdriver, you can do this easily.

My Hoover savvy won't turn on


Unplug from Power FIRST!
If you can find the backside ot the OFF/ON switch you can see if it is worn out or broken. Do you have a voltage tester? If so carefully expose the leads into the switch, then plug in power, and test if both sides are HOT (110volts) when switch is turned on. If so, then it may be the motor is bad. If only one side is hot then the switch is likely bad.
Take to a VAC Store to get a replacement.

This is a parts schematic for your hoover savvy. You have to take off the brush guard on the bottom and also the cover on top (there is a screw under the round hoover logo). You will then see how the belt is attached. Very easy to do. Hope this helps

Hoover savvy upright, replaced belt, but brushes will not turn


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.

Hoover US8174-900 Savvy Bagless


It uses a cogged belt, turn it over, remove the bottom plate, remove the other screws from the bottom, turn vac back over and remove the Hoover emblem, there is a screw there to remove and the top comes off, then you can get to and replace the belt.

Hoover savvy no suction on carpet setting


Check to make sure you hear the vac. motor is running when in that position. The switch in the handle could be bad if it is not.

Hoover Savvy on-off switch does not work (very intermittant)


Hi All-

I found the solution to this issue. You need to take the switch apart. Having a set of small jewelers screwdrivers from radio shack helps a lot.

First, take the switch enclosure off to expose the mechanics of the switch. There are 3 clips on either side that need to be worked free.

There are 4 springs inside the switch that push down 2 metal contacts (one other spring is used to hold the switch in position). If you expand all 4 springs (stretch them out about double there normal size) the increased pressure helps the switch make more solid contact and prevents arching which is what ruins the switch in the first place. After you stretch the 4 springs be sure to clean up the contacts on the switch chassis with a wire brush.

On the slider part of the switch there are 2 contacts which also need to be cleaned up. If you have a dremil tool use it to file a point on opposite the ends of the messed up contact. Be sure there are no burs after making the points . If there are burs the contacts will hang up and springs can't do there job. This is because there are slots the contacts need to float in on the plastic slide.

With the 4 springs stretched out it will be very difficult to put the switch back together. However, with some patients, mini needle nose pliers and jewelers screwdriver set you can be successful.

You may want take the switch circuit board off the vac before putting the switch back together (to do this remove the handle). The switch is much easier to put back together removed from the vac and on a clean well lit table. Assemble the switch in a place where you can find small parts on the floor if the contacts or springs shoot out during reassembly

This hoover savvy runs like a champ now, no more arching in the switch to destroy the contacts.

I would only attempt this if you are mechanically inclined… worst case scenario however is you break the switch and need to order the replacement though… oh yea make sure the thing is unplugged when you do the above procedure.
