Computer-implemented methods for hosting online video games are provided. One method includes generating a plurality of video frames. The method includes initiating a sending of each one of the plurality of video frames to a client. Each of the video frames that is sent is compressed. The method includes stopping the compression and sending of video frames when one of the plurality of video frames is taking longer than a frame time to compress and send. A frame time is defined as one over a frame rate, and wherein stopping the compression of video frames includes ignoring said video frames by an encoder. The method includes continuing to compress and send audio data to the client when one or more of said plurality of video frames are not sent to the client. The client is configured to display a received video frame for more than one frame time when a video frame is not received due to the stopping of the compression and the sending, and the client will have a reduced frame rate for display of said plurality of video frames during said stopping of the compression and the sending.

A wringing assembly may include a plurality of spaced apart pressure applicators, such as may be used for applying pressure to a mop element having a cleaning, absorbent or wiping material supported on the mop element. The pressure applicators may be supported so as to be centered or symmetrical on each side of a center of a wringing surface. The wringing assembly may include a substantially centered actuation element such as a handle. An actuation element on a wringing assembly may also include a receptacle for an element of a mop or other cleaning tool, such as a handle A bucket positioning device includes a spring-loaded assembly having a hook for a bucket rim and a base for engaging a bottom of a bucket or a wheel unit.

A wringer, for example for mops, includes one or more positioning elements to position a mop at least in one dimension in the wringer, for example to a desired depth in the wringer, to wring the mop. The positioning elements far other than a bottom surface of the wringer. A wringer is also disclosed in which a wringing surface is moved toward another wringing or a base surface in a drawing or pulling motion. A wringer is also disclosed where the wringing operation can be activated by a pivoting or other mechanism that can be operated from at least two positions, a plurality of spaced apart locations, from handles, or by way of structures positioned outside of a wringing envelope defined by wringing plates or other components contacting a mop element. The structures can be used to operate the wringer even if a handle of a mop element extends outward of the wringing envelope.

A mop draining bucket adapter configured to attached to a bucket and having a mop compression assembly configured to be disposed within the bucket and with two compression plates hingedly coupled to the respective lower ends thereof and with a tether member coupling respective upper ends of the compression plates. Each of the compression plates have a plurality of holes defined thereon, defining a compression zone sized to receive a cleaning head of a cleaning device, and operably configured to rotate about their respective lower ends in a plate compression path to vary a volume of the compression zone and compress the cleaning head of the cleaning device to remove liquid retained therein.

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.
