Abstract: A suction nozzle for a portable hard surface cleaning apparatus includes a suction nozzle housing having a first and a second housing half-shell which between them form a suction duct which extends from a suction opening to a suction duct end section to which a source of vacuum can be connected for creating a suction flow. Arranged at the suction opening is a replaceable squeegee lip, and the two housing half-shells each have at least one holding element adjacent to the suction opening, and a holding section of the replaceable squeegee lip is arranged between the holding elements of the two housing half-shells. In order to improve the suction nozzle in such a manner that it is reliably held at the suction opening, the holding elements in each case form an engagement with the holding section.

Abstract: A window and glass cleaning device includes a cleaning head and an elongated handle configured to be grasped by a user. The handle has a first end connected to the cleaning head and a second end configured to be connected to an extension handle. A fluid container is housed by the handle, and a spray nozzle is carried by said handle at a position approximate the first end of the handle. A pump is carried by the handle and connects the fluid container to the spray nozzle. The pump includes a pump actuator. An electric motor is carried by the handle and is operatively connected to pump actuator to drive the pump actuator in the pumping of fluid from the container through the spray nozzle. A power source and an electric switch are carried by the handle. The electrical switch is operatively connected to the power source and to the electric motor and is operable by the user to connect the power source to the electric motor to facilitate the pumping of said fluid through said spray nozzle.

Abstract: An ornamental design and a portable appliance that has been specifically designed to remove Bird droppings from all transportation vehicles and surfaces on land and sea. The device is a multi purpose and battery driven portable BIRD DROPPING removal system “BDR”. This is a hand held device that embraces a “DC” Direct Current powered, A Low Torque motor, driving several gears and then right angled rotating disks that holds a disposable sponge disk pad that is uniquely saturated with a cleaning liquid solution. The rotating saturated disk is specifically designed to wipe clean hardened bird droppings that are deposited on surfaces by removing the bird droppings in a quick time as not to smear the bird dropping on its surface. Even though the surfaces are exposed to the sun and intense heat the Bird dropping remover will separate the bird dropping from the surface without damage to the paint or other surface material. The removal is achieved in part, by utilizing the optimum low speed and low torque rotating mechanism, and at the optimum torque, along with the saturated sponge disk solution.
