The bucket hoist, windlass, and Mohtes mohtes (charsa or charus) are all modifications of the simple [[Rope and bucket]] system, to improve ease and efficiency.

There is a family of devices for pulling up a container of water on a rope. The simplest form for this is a [[rope and bucket]], which in an improved form has a simple windlass, i.e. a hand operated winch, to increase the leverage and hence the size of bucket that can be lifted.

==Suitable conditions==

The number of Mohtes mohtes in use today is still in the order of a million or more, so this device remains of considerable importance in some regions.
