A mop bucket cart (or mop trolley) is a wheeled bucket that allows its user to wring out a wet mop without getting the hands dirty.
 
The wringer on the bucket allows the user to easily press excess water out of the wet mop, preventing floors from becoming overly saturated and slippery.
 
Mop buckets hold water and chemicals for cleaning floors. Sometimes called mop pails, they have handles to make it easier to transport and maneuver. Some of them use steel material to prevent rust and handle added pressure. There are also plastic buckets that offer lightweight durability.
