Glossary
Battery capacity
The capacity of the battery installed in the cleaning machine with the appropriate power supply.
In theory, a higher capacity allows you to work longer on a single charge, but in practice everything is not so simple. Firstly, the autonomy is also affected by the energy consumption of the machine, and it is determined mainly by the engine power (see above). Secondly, the actual amount of energy stored in the battery depends not only on the capacity in ampere hours, but also on the operating voltage in volts. Therefore, only batteries with the same voltage can be compared with each other in terms of capacity in Ah (or convert ampere-hours to watt-hours using a special formula and compare the results). And it is best to evaluate the autonomy of the unit by the directly stated operating time (see below).

Noise level
The noise level created by the harvesting machine during operation.
Low noise levels are important for the comfort of both the operator and others; the latter is especially true in some specific places such as hospitals or kindergartens. On the other hand, the higher the power, the louder, as a rule, the unit operates and the more difficult it is to reduce this noise to a certain level; despite the fact that in many cases high volume operation is not a particular problem. So you should specifically look for a “quiet” cleaning machine only if a low noise level is more critical for you than high cost and/or reduced power.
When assessing specific loudness values, it is worth considering that the decibel used to indicate the noise level is a non-linear quantity. Therefore, the easiest way is to evaluate specific values using comparative tables. Here's a simplified table for the range that most modern harvesting machines fit into:
55 dB - background noise in an office without special noise sources;
60 dB - loud conversation;
65 dB - city street with average traffic intensity;
70 dB - a conversation between several people in a raised voice.
75 dB – high power vacuum cleaner.
80 dB - traffic noise on a busy street.

Power cord length
The length of the mains cord provided in the machine with the appropriate power supply (see "Power supply").
A long cord allows you to move further away from the outlet but can get tangled under your feet and create inconvenience. Therefore, manufacturers choose the length of the power cord by the specs of a particular model: for example, a window robot (see "Type") is quite enough 4 – 5 m, and in heavy scrubbing units, the length of the wire can exceed 20 m.

Weight
The total weight of the cleaning machine. Usually, weight is indicated with empty tanks for detergent, waste, fuel, etc. At the same time, additional equipment, such as side brushes, may or may not be taken into account. Such equipment has a very small weight compared to the machines themselves. And, when installed/removed, does not seriously affect the mass of the entire machine.
