Working width
The width of the space that a harvester can cover in one pass. In models with removable side brushes (see above), this paragraph indicates figures only for the unit itself, and the width of the grip with brushes is specified separately (see below).
The large working width is convenient when working in large open spaces - it allows you to complete the job in fewer passes. In turn, machines with a small working width - and, accordingly, a relatively narrow body - are more passable, they are better suited for environments with a large number of hard-to-reach places. So you should choose based on this parameter taking into account the characteristics of the premises/territories being served.
Waste tank
The volume of the garbage tank provided in the design of the harvester. The garbage tank is equipped with sweeper and suction sweeper units (see above). The larger the capacity of this container, the more garbage it can hold and the less often it will have to be emptied. On the other hand, this indicator can significantly affect the weight and dimensions of the sweeper, despite the fact that for small volumes of cleaning (for example, occasional sweeping of the path at the exit from the garage), a capacious garbage tank is simply not required. Therefore, manufacturers usually choose the capacity of this tank based on the general class of the harvester and the work for which it is designed.
Autonomy time
Operating time of a battery-powered cleaning machine on one charge of a standard battery.
This parameter itself is quite approximate: it is most often indicated for standard operating modes and simple conditions. However, the actual autonomy is usually not very different from the stated one; so, based on the stated operating time, it is quite possible to both evaluate the capabilities of different models and compare them with each other.
Filter area
The working area of the filter, which is regularly equipped with a cleaning machine.
In this case, we are talking about a filter designed for fine dust. Its area as a whole is a secondary parameter, it is selected by the manufacturer in accordance with the general level and performance of the unit — so that the filter performs its function efficiently enough and at the same time is not too bulky. If models with similar characteristics differ in this indicator, note that a larger filter is more expensive and takes up more space, but it has to be cleaned less often.
