Toilet flushing systems installed in a toilet reservoir. A toilet reservoir stores a fluid that pours into a toilet bowl for carrying waste away from a toilet. Exemplary toilet flushing systems may include a flush sleeve having a sleeve bottom and sleeve top. The exemplary sleeve bottom may connect to a bottom of the toilet reservoir around a reservoir drain. The flush sleeve may be capable of being raised in a raised orientation such that the sleeve top is above the fluid in the toilet reservoir to prevent the fluid from entering the reservoir drain. Exemplary toilet flushing systems may include a flush sleeve actuator that lowers the sleeve top of the flush sleeve below a fluid level in the toilet reservoir to allow the fluid to flow through the flush sleeve into the reservoir drain.

Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a toilet tank, a flush valve, a rim inlet port and a rim flow path (which may be an isolated rim path) extending from an outlet of the flush valve to the rim inlet port. The cleaning system has a reservoir for holding a liquid cleaning agent having an outlet port in fluid communication with the interior space of the reservoir body; a housing to receive the reservoir, a supply conduit in fluid communication with the interior of the reservoir; a flow control device capable of controlling flow through the supply conduit; and a control system activatable by an actuator feature, wherein upon activation of the actuator feature, the control system is adapted to initiate a clean cycle by: operating the flow control device for a first period of time sufficient to deliver a dose of a liquid cleaning agent from the supply conduit to an interior space of the flush valve in a closed position, the flush valve configured for delivery of fluid to the rim inlet port, and operating the flush valve to open the flush valve to introduce flush water to carry the dose of a liquid cleaning agent through the rim inlet port into the toilet bowl.
