A cleaning pad includes a mounting surface disposed on a top side of the cleaning pad. The mounting surface is configured to provide a mechanical connection to an autonomous cleaning robot. The cleaning pad includes a first outer layer disposed on a bottom side of the cleaning pad, the first outer layer having a first coefficient of friction; and a second outer layer disposed on the bottom side of the cleaning pad, the second outer layer having a second coefficient of friction less than the first coefficient of friction.

The baseboard-cleaning implement is a handheld device. The baseboard-cleaning implement is a hand tool. The baseboard-cleaning implement is configured for use in cleaning a baseboard. The baseboard-cleaning implement is a cleaning brush. The baseboard-cleaning implement is configured for use with a liquid soap. The baseboard-cleaning implement includes a handle, a plurality of interchangeable brushes, a fastener, and a control circuit. The fastener removably attaches any brush selected from the plurality of interchangeable brushes to the handle. The handle contains the control circuit. The control circuit pumps the liquid soap from the handle into the selected brush. The control circuit rotates any brush selected from the plurality of interchangeable brushes. The direction of rotation of the selected brush is selectable.

A remaining water suction device may include: a suction nozzle, a water separation chamber configured to be connected to a discharge port of the suction nozzle and provided with a water discharge port and an air discharge port, and a buffer tank configured to be connected to the water discharge port and store water separated from the water separation chamber. The remaining water suction device may include a water transfer pump configured to transfer the water stored in the buffer tank, a water storage tank configured to store the water transferred through the water transfer pump, a suction fan configured to provide a suction force to the air discharge port, and a suction motor configured to drive the suction fan.

A cleaning method and apparatus for elevated structures and ceilings, such as open girder truss systems, utilizes a multi-rotor blade helicopter/drone together with a contaminant entrainment system. More specifically, the drone includes a contaminant entrainment system including a vacuum and filter for entraining the contaminants dislodged from the elevated structures, a cleaning head to engage the surface to be cleaned, a system to guide the drone's flight path proximate the elevated structures to be cleaned, and optionally a power tether to reduce battery weight and increase the flight time of the drone.

An aircraft that can fly stably when water is discharged from a hose installed on the airframe, and an aircraft system, are provided. The aircraft system can include a master aircraft, slave aircrafts and a remote control device. The aircraft preferably fly as a unit. Each slave aircraft can include four rotary blade portions having propellers, and a suspending means for suspending a part of a hose. The master aircraft may include four first rotary blade portions having first propellers arranged to rotate in a horizontal plane, four second rotary blade portions having second propellers arranged to rotate in a vertical plane, and a nozzle on which a tip end part of the hose is installed. The direction of the center axis of the nozzle is parallel to the direction of the rotational axes of the second propellers.

The present invention discloses a high flow low pressure suction device. The device is a non-contact suction device based on multiple stage turbulence based low pressure suction mechanism which comprises fan(s) or rotating impeller(s) for drawing air/fluid/slurries operates without any seal between the device and the sucked surface. The device compounds this turbulence based low pressure generation along with Bernoulli's principle to yield a high efficiency suction device. The device implements the above concept by making the air/fluid/slurries flow through two or three zones selected from the acceleration zone(s), turbulence zone(s) (high turbulence zone) and smooth zone(s) (minimum turbulence zone). The device works by pulling the air/fluid/slurries into the vacuum chamber, accelerating the air/fluid/slurries, creating turbulence in the air/fluid/slurries in a thin region near the perimeter in order to cause a drop in pressure and then maintaining pressure over a large bottom area and finally exhausting the air/fluid/slurries through the fan(s)/rotating impeller(s).
