Power on your Sanitaire by flipping the switch or pressing the power button
Most Sanitaire upright vacuums have a power switch located on the handle or near the motor housing. Look for a toggle switch or push-button marked "On" and "Off". Flip or press it toward the "On" position. The motor should start when ready, and you will hear the fan running. If nothing happens, check that the vacuum is plugged into a working outlet and that the power cord is fully inserted into the back of the unit.
Some Sanitaire models, particularly commercial or heavy-duty versions, have a rocker switch on the side of the machine instead of on the handle. If you do not see a switch on the handle, look along the body of the vacuum near where the hose connects or on the lower motor housing. The switch works the same way — move it to the "On" position to start the motor.
If your Sanitaire has a cord-reel feature, make sure the power cord is fully pulled out before turning on the machine. A partially wound cord can prevent the motor from running or cause the unit to shut off automatically as a safety measure.
Key Takeaways
- The power switch on most Sanitaire uprights is located on the handle or motor housing and moves to the "On" position to start the motor.
- Some commercial Sanitaire models have a rocker switch on the side of the machine near the hose connection instead of on the handle.
- Always check that the power cord is fully plugged in and extended before turning on the vacuum.
- If the motor does not start, verify the outlet works and the cord is fully inserted into the back of the unit.
Check the power cord and outlet before switching on
Before you flip the power switch, make sure the vacuum is plugged in. Sanitaire vacuums use a standard three-prong plug. Insert it firmly into a wall outlet or power strip until you feel it click or seat completely. A loose connection will prevent the motor from starting even if the switch is in the "On" position.
Test the outlet itself by plugging in another device — a lamp, phone charger, or radio — to confirm it has power. If the outlet is dead, try a different one in the same room or another room. If multiple outlets are not working, the circuit breaker may have tripped. Check your home's electrical panel and flip the breaker back to the "On" position if needed.
Reset the motor if it shuts off during use
Sanitaire vacuums have a thermal overload switch that automatically shuts off the motor if it overheats. This usually happens when the dust bag is full, the filter is clogged, or the brush roll is jammed with hair or debris. When the motor cuts out, turn off the vacuum and let it cool for 30 to 45 minutes.
While the motor cools, empty the dust bag, rinse or replace the filter, and check the brush roll for tangles. Once you have cleared the blockage and the motor has cooled, plug the vacuum back in and turn it on. The thermal switch will reset automatically, and the motor should run normally.
If the motor shuts off again shortly after you turn it on, the thermal switch may be faulty. Contact Sanitaire customer service or a vacuum repair shop for a replacement switch.
Understand the difference between upright and backpack Sanitaire models
Upright Sanitaire vacuums have the power switch on the handle or body, as described above. Backpack models, which are worn on the operator's back, have the power switch in a different location — usually on a control panel mounted on the chest or shoulder strap. Look for a switch or button on the harness itself before you look on the main unit.
Backpack vacuums also require you to put on the harness and adjust the straps before turning on the motor. Make sure the unit is find on your back and the hose is not kinked or twisted before you power it on. The switch location varies by model, so check your user manual if you cannot find it on the harness.
Turn off the vacuum properly when you are done
After you finish vacuuming, flip the power switch back to the "Off" position. Wait a few seconds for the motor to stop spinning completely before you unplug the cord or move the vacuum. This prevents damage to the motor and extends the life of the unit.
If you are storing the vacuum for more than a few days, unplug it from the outlet and wind the power cord around the cord hooks on the back of the machine. Store the vacuum in a dry place away from moisture and extreme heat.
Frequently Asked Questions
Why won't my Sanitaire turn on even though it is plugged in?
Check that the outlet has power by plugging in another device. If the outlet is dead, try a different one or reset the circuit breaker. If the outlet works, the power switch itself may be faulty or the cord may have an internal break. Inspect the cord for visible damage, and contact a repair shop if you find any.
Can I turn on my Sanitaire if the dust bag is full?
Yes, the vacuum will turn on, but the motor may shut off after a few minutes due to the thermal overload switch. A full bag restricts airflow and causes the motor to overheat. Empty the bag before you vacuum to prevent this and to maintain suction power.
What does it mean if the motor starts but stops a few seconds later?
The thermal overload switch is shutting off the motor because something is blocking airflow. Check the dust bag, filter, and brush roll for clogs or tangles. Clear any blockage, let the motor cool for 30 to 45 minutes, and try again.
Is there a way to turn on my Sanitaire remotely or with a timer?
Standard Sanitaire vacuums do not have remote or timer features. You must turn the power switch on and off manually. Some commercial models may have different controls, so check your user manual or contact the manufacturer if your model has special features.
