An apparatus for cleaning a surface includes a liquid delivery system for storing cleaning liquid and delivering the cleaning liquid to the surface to be cleaned, a fluid recovery system and a control system. The control system includes a controller that is coupled to a sensing assembly. Methods of operating the same include sensing foam or liquid with the sensing assembly.

Apparatus for cleaning a surface

A surface cleaning apparatus includes a fluid delivery system and a recovery system, and is operable in a plurality of user-selectable cleaning modes, including at least a wet vacuuming mode and a dry vacuuming mode. The fluid delivery system has a fluid dispenser that may comprise a spray manifold for wetting a brushroll. The recovery system includes a tank that may have a baffle to separate liquid and/or debris from a working airstream. Operating parameters of the apparatus may be automatically adjusted based on a detected floor type. The apparatus can dock with a tray for recharging and/or self-cleaning.

Surface cleaning apparatus

An apparatus for cleaning a surface includes a liquid delivery system for storing cleaning liquid and delivering the cleaning liquid to the surface to be cleaned, a fluid recovery system and a control system. The control system includes a controller that is coupled to a fluid level sensing assembly. Methods of operating the same include sensing foam or liquid with the fluid level sensing assembly.

A wireless response system and method of retrieving user selections includes providing a plurality of response units, each having a wireless response transceiver and an input device and a plurality of base units, each having a wireless base transceiver. The wireless response transceiver is adapted to transmitting a response transmission in response to receipt of a base transmission. The base transceiver is adapted to transmitting base transmissions and receiving response transmissions from the response units. Each of the base units and each of the response units are assigned communication identification. Base transmissions include a unique base address of the base unit transmitting that base transmission. Response transmission includes the base address of the base transmission to which that response transmission is responding. Each of the base units processes response transmissions having its base address and does not process response transmissions not having its base address.

Audience response system and method with multiple base unit capability

A frequency agile wireless response system and method of retrieving user response data from a plurality of users includes providing a base unit and a plurality of handheld response units, each communicating with the base unit over a wireless communication link using a frequency agile communication protocol. Base signals are sent with the base unit to the response units over the wireless communication link. Response signals are sent from the response units to the base unit over the wireless communication link. The base signals include a master transmission and at least occasionally include an extension transmission. The master transmission includes information establishing a time mark for the response units. The master transmission also includes information enabling the response units to receive any extension transmission associated with that base signal.
