In an example embodiment, a floor sander comprises a motor having at least two selectable speeds, and a sanding adaptor driven to rotate about a rotational axis by the motor. The sanding adaptor includes a planetary disk that rotates about the rotational axis of the sanding adaptor. In addition, the sanding adaptor includes a plurality of sanding head units, each of which is coupled to the planetary disk for independent rotational movement. Each sanding head unit therefore rotates about its own rotational axis independently of any other sanding head unit or the planetary disk. An isolator is also provided, and is positioned generally between the planetary disk and the motor.

In combination, a removable tool may be selectively attached to the cleaning wand of a carpet extractor to alternatively clean hard surfaced floors, such as grouted tile and when not attached, clean carpeted floors. The removable tool may be sold as an aftermarket item for existing carpet extractors. A method of using the carpet extractor with the removable tool allows the apparatus to fulfill dual purposes, e.g., cleaning hard surfaced floors and when the tool is attached to the cleaning wand, and when the tool is removed from the wand to clean carpeted floors.

A system for monitoring carbon monoxide in an environment which includes an apparatus emitting carbon monoxide, such as an internal combustion engine. A carbon monoxide sensor measures a concentration of carbon monoxide in the environment and provides an electrical signal to a processor that is representative of the measured concentration of carbon monoxide. The processor determines the concentration of carbon monoxide corresponding to the electrical signal, provides an output signal at or above predetermined carbon monoxide concentration thresholds, calculates an estimated carboxyhemoglobin level for the operator corresponding to the carbon monoxide concentrations calculated over time, and provides an output signal at or above predetermined carboxyhemoglobin thresholds. The signals are then received by one or more devices which provide textual, visual, and/or audible warnings indicating that environmental concentrations of carbon monoxide have caused a predetermined warning threshold to be met or exceeded. The signals may also be received by a device which shuts down the carbon monoxide generating apparatus.
