This term refers to how well a vacuum cleaner is able to clean along "edges" such as walls and baseboards, furniture, etc. Because a vacuum cleaner has a housing that encloses the brush roll, special designs must be employed to enable successful edge cleaning. These include designing the brush roll so that bristles reach very close to the housing, stationary brushes mounted on the outside of the cleaning nozzle, air channels to increase airflow to edges as well as combinations of these approaches.
Canister vacuum cleaners that use power nozzles need to get electrical power to the motorized cleaning head. In the past this was done by attaching an electric cord to the outside of the vacuum hose and then down the wands with special straps. An electric vacuum hose is manufactured so that the electrical wires are internal. This eliminates the inconvenience of external cords and makes using the vacuum cleaner much more enjoyable.
Electric Motor Brush
This is a Bosch trade name for their power nozzle. See "Power Nozzle".
Electric Power Display
This is an electrical display that indicates at a glance the level of power at which the vacuum cleaner is operating.
Electronic Adjustable Power Regulation
See "Electronic Suction Adjustment".
Electronic Suction Adjustment
There are two ways that vacuum suction can be adjusted; reducing the power to the vacuum motor or opening a relief valve that bypasses air and lowers the suction at the tool. Electronic Suction Adjustment refers to the reduction of power to the motor, which slows it down and in turn reduces suction. Also referred to as a "Speed Control".
A filter that is made up of synthetic fibers that develop an electrostatic charge as friction is applied, which in vacuum cleaners, air purifiers and furnace filters is produced by air flowing across the filter. This electrostatic charge is generally effective in trapping particles 1 micron or larger making electrostatic filters capable of capturing house dust, skin flakes, animal dander, pollen and mold spores.
Ergogrip Plus™ Handle
A Bosch trade name for their ergonomically designed hose handle. See "Ergonomic".
Ergonomic refers to a design principle that seeks to make using a product as easy and as stress and strain free as possible. In the vacuum cleaner industry, ergonomic principles are often employed in handle designs, swivel characteristics of cleaning heads and so on.
Falling under the cool mist category there are several types of evaporative humidifiers. The most basic utilize a filter pad to absorb water and a fan that blows air across the pad to release moisture into the air. More advanced systems such as those made by Venta and Air-O-Swiss utilize special evaporative discs and do not require pads.
