Suction power
Working power of the machine for suction.
The effort with which the unit draws in pollution during operation directly depends on this indicator. The greater this effort, the higher the quality of cleaning and the more effective cleaning. On the other hand, even in the heaviest and most performant models, the suction power does not exceed 1200 W — it simply does not make sense to increase it further. In addition, we note that with an increase in the width of the grip, the suction power must also be increased, otherwise, the efficiency will decrease. It means that only models of the same type with the same or almost the same working width can be compared in terms of suction power.
Charging time
The time required to fully charge the battery of cleaning machine (see "Power supply").
The larger the battery, the longer it may take to charge it. On the other hand, this moment also depends on the type of battery. In addition, special technologies are being used to speed up the process. So two machines with a similar battery capacity can differ in charging times.
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.
