A portable cleaning device with interchangeable cleaning tools and an alert system may include an elongate rod having a first end and a second end, a handle attached to the first end of the rod, a cleaning attachment removably engaged with the second end of the rod, a handle grip sensor operatively attached to the handle and a cleaning attachment pressure sensor operatively attached to the cleaning attachment, and an indicator operatively attached to each sensor, the indicator designed to alert a user when the sensor is activated.

The invention discloses a self-wringing mop system comprising a main body (1), a head (6) couplable to the main body (1), and a bucket (7) having a particular wringer (71). The interaction between the elements making up this system reduces the effort a user needs to make to wring the mop. The invention is also directed to each of the individual elements, in particular the main body (1), the head (6) and the bucket (7).

A safety waterproof invisible switch and a sanitary ware are provided. The safety waterproof invisible switch comprises a button switch, a first member, a second member, a first magnet, and a second magnet. The first magnet is disposed on a button of the button switch, and the second magnet is disposed on the second member. The first member has a hollow cavity. The button switch disposed with the first magnet is disposed in the first member. While the second magnet is adjacent to or in contact with the first member and when magnetic poles of a same polarity of the first magnet and the second magnet oppose each other, the button of the button switch is moved in a pressed direction of the button by a repulsive force.

A spin mop and bucket system to assist in dewatering a mop is disclosed. The spin mop may have a handle assembly slidably connected with a spiral member, and a mop head that is attached to the spiral member. When the handle assembly moves along the spiral member, the spiral member rotates causing the mop head to rotate. The mop head may articulate relative to the handle assembly and may be pivotally connected to the spiral member and also pivotally connected to a swivel member located between the spiral member and a mop head base. The mop head may be received in a wringer basket of a bucket assembly, such that when the mop head spins, the wringer basket spins to expel any excess fluid from the mop head.

Disclosed is a method of controlling a plurality of robot cleaners, the method including a first step of docking a first robot cleaner and a second robot cleaner with a first docking device and a second docking device, respectively, a second step of checking whether the first robot cleaner is undocked from the first docking device, and a third step of if the first robot cleaner docked with the first docking device again, undocking the second robot cleaner from the second docking device.

A flocculation system is provided including a vessel having an open top. The flocculation system also includes a sidewall comprised of a water-impermeable material. The flocculation system further includes a first bottom comprising the water-impermeable material. The flocculation system further includes a second bottom having a floc filter that passes flocs and prevents the passage of a cleaning tool. The flocculation system further includes a floc trap below the second bottom. The floc trap includes a space defined by the sidewall, the first bottom, and the floc filter. In some implementations, the flocculation system includes a flocculant disposed on the sidewall, the floc filter, or the first bottom.

A mop strand bundle a plurality having elongated first elongated cleaning tendrils having a first surface roughness and oriented in parallel relationship to one another and connected to one another in at least one location. The mop strand bundle also includes at least one elongated second cleaning tendril and a head band. The second elongated cleaning tendril is oriented in parallel relationship to at least one opposed elongated edge and is in moveable relationship with at least one first cleaning tendril. The elongated second cleaning tendril has a second surface roughness greater than the first surface roughness. The headband is positioned in overlying fixed relationship to the plurality of elongated first cleaning strands and connected to the at least one elongated second cleaning tendril at a location between the first and second ends of the plurality of elongated first cleaning tendrils.

A cleaning tool includes a shaft extending from a proximal end to a distal end, where the shaft has a handle at the proximal end and a tool head at the distal end; and a sock removably mountable on the tool head. The tool head may include a through hole, and the sock may include a fastener with a first coupling member and a second coupling member, where the first and second coupling members are constructed to align with and couple through the through hole on the tool head. Alternatively the tool head includes one or more coupling members and the sock includes one or more corresponding coupling members constructed align with and couple with the one or more coupling members on the tool head.

A DuraLock scrubber and scraper attachments with replaceable surface scrubbing and scraping capability, that includes providing a removable/replaceable surface scrubbing and scraping attachments, and attaching the elements to the mop head holder for scrubbing and scraping the floor surface. This provides a mop handle with surface scrubbing and scraping capability and includes an attachment for rigid connection to a mop handle, which is adapted to carry replaceable surface cleaning element(s). The replaceable elements can be a scraper, scrubbing pad or bristles or other abrasive materials that can be interchanged or replaced depending upon the job or as the components wear without requiring removal of the mop head and further allows the replacement of the mop head without requiring removal and reinstallation of the elements.

A mop tool is provided. The mop tool includes: an elongated stick; a cleaning head which includes a head body that has a coupling portion rotatably coupled to one end of the stick, and a gap portion that extends from the coupling portion of the head body toward at least one side of the head body; and a rotation control element which is installed on the stick so as to be movable along the stick. The rotation control element includes a locking member which is releasably coupled to at least a part of the head body which adjoins the gap portion, and restricts a relative rotation between the cleaning head and the stick.
