Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

Abstract: In a method of query derivation in an observation platform a signal from a first communication device is received at a second communication device that is associated with a computer system. The computer system is associated with an organization and a first characteristic of the signal corresponds to an audible source. The signal is parsed, by the computer system according to a policy, to determine metadata associated with the signal, wherein the first communication device is operated by a user and wherein the policy dictates rules for use of the metadata. The computer system determines a prior user history of the user. The computer system converts the audible source of the signal to text or machine understandable language. The computer system derives a query related to the organization based on at least one of the prior user history, the metadata, and the text or machine understandable language.
