My Hoover Remedy Multi-cyclonic vacuum has no suction to pick up from carpet

SOURCE: picks up poorly

I'd check thoroughly, the hose right next to the bush roll.

very easy. you have clog. take the brush off look where the hole is thats where the clog is. it might be in there you might have to take the housing off of the motor

My M.R. cleaner had the same problem. I found the drive belt for the beater bar was broke.
Turn the cleaner over when running and if the beater isn't turning, then the belts gone.
New belts on E-Bay £4-$7 for 2.

SOURCE: I have a Eureka Altima vacuum cleaner that doesn't

That means that you need to replace the belt. Here is the belt you need to replace and the manual which has instructions:
