A ride-on, wheeled toy picks up small objects from a plane surface. The ride-on toy can be driven by the feet of a child sitting on the toy or by the hands of a person standing behind the toy. The pick-up mechanism of the toy is a continuous gear and belt system with flexible sweeping fins. The pick-up mechanism can be activated or deactivated by a push button or switch.

A cleaning roller for a cleaning appliance, in particular a wiping roller for a wet cleaning appliance, or a cleaning appliance having such a cleaning roller processes an area to be cleaned. The cleaning roller has a roller core that can rotate about a longitudinal axis and has a bearing for a drive shaft and a roller cover surrounding the roller core in the circumferential direction. The roller core, based on a cross section perpendicular to the longitudinal axis, has several spring elements formed beside one another in the circumferential direction of the cleaning roller, each of which extends from the bearing to the roller cover.

A sponge roller, a cleaning roller assembly, and a floor cleaner. The sponge roller includes an outer layer and an inner layer. The outer layer is sleeved on the inner layer; the inner layer is made of non-absorbent sponge, and the outer layer is made of absorbent sponge. The sponge roller can be made with a large thickness, thus improving the cleaning capacity of the cleaner. The water is mainly stored in the outer layer, so it can be squeezed out without the exertion of much more external force, and thus the resistance against the rotation of the sponge roller is negligible, thus saving the energy consumption.

A floor cleaner, comprising: a cleaning roller, a water channel, a clean water tank, a clean water supply system, a wastewater tank and an air pump. The water channel is configured to cover the cleaning roller with an airtight seal. The clean water tank, the clean water supply system and the water channel are in communication with each other, and the clean water supply system is configured to allow clean water in the clean water tank to flow to the water channel. The wastewater tank comprises a chamber for recovery and store of wastewater, and the chamber is provided with a wastewater inlet and an air extraction opening. The wastewater inlet and the water channel are in communication, and an inlet of the air pump and the air extraction opening of the wastewater tank are in communication.
