The present invention relates to the field of cleaning implements, and, more particularly, to the field of electrically operated mops for spraying cleaning liquids onto a floor. A cleaning implement includes a liquid delivery system for providing a cleaning liquid to a surface to be cleaned having a canister for storing a liquid, an electrical motor driving a pump, and a voltage source for engerizing the electric motor. A support head is pivotally attached to the handle for releasably receiving a cleaning sheet. The handle includes a switch and is formed from a plurality of handle sections. Each handle section has at least one electrical connector which is electrically connected with an electrical connector of an adjacent handle section so that the switch can activate the electrical motor. The support head can be configured to allow visual inspection of the cleaning sheet through the support head during use. The canister is provided with plurality of side walls and vent valve having a cracking pressure of at least about 0.6 Kpa, wherein the canister is substantially in the form of a parallelogram in a plan view cross section and wherein one or more of the side walls has a plurality of grooves.
