This sounds like the Thermal Switch in your motor tripped. All Riccar vacuum cleaners have a motor reset switch, that will shut the motor down when it gets hot. Usually it's caused by a full bag, clog, or dirty filter.
Try resetting the thermal switch first. If this doesn't work, you may have done some more serious damage to the motor, and it might be a good idea to take it into a local Riccar dealer in your area.
Here's a step by step guide on how to check the reset switch on your Riccar 8850:
To reset the thermal fuse:
- Unplug the vacuum cleaner
- Check for problem – over–filled bag, clog in hose, clogged filters, etc.
Remove the vacuum bag, and see if you can visibly see any obstructions, or replace the bag if it's full:
Also inspect the Secondary filter while you have the vacuum bag removed from the machine. If the filter is clogged or dirty, rinse under warm water, and air dry completely before reinstalling it into the vacuum. It's best to wash this filter every 30 days, and replace after 4-5 washings.

Your Riccar 8850 also has a set of exhaust filters that are on the front of the vacuum, near the bottom where the upright body meets the agitator housing. These filters when clogged may also cause the thermal switch to trip. These filters are recommended to be replaced every 6-12 months, and are not recommended to be washed.

It's also possible that you may have clog in the suction port inside of the agitator housing. Remove the bottom plate from the vacuum, and look for the tube that runs on the left hand side from the tray to the rear of the agitator housing. Make sure that this tube is clear from obstructions:
Locate "tripped" fuse – the small white button located on the bottom of the back side of
the main body (roughly one inch to the right of the left wheel)
Using a pencil, paper clip or other pointed object, push the reset button in, you should hear a clicking noise when it resets.
Plug the vacuum cleaner back into the wall, and try turning the vacuum on. It should come right back on. If not, it's best to take your machine into a local Riccar authorized repair facility for further more advanced diagnosing.
