Suction width
Suction width provided by the unit. It is indicated mainly for floor scrubbers and window vacuums (see "Type"). In the first case, it refers to the width of the suction beam; in the second — the width of the working nozzle.
The width of the suction beam in scrubber dryers is usually slightly larger than the overall working width — it allows one to collect the water used in cleaning effectively. The size of the suction beam in some models of this type reaches 75 cm. In turn, in window vacuum cleaners the suction width corresponds to the actual working width. Most often, this figure is about 28 – 29 cm. it is believed that such values give an optimal ratio between performance and dimensions/weight of the unit. However, there are also more miniature models — in some devices, the width of the nozzle does not exceed 17 cm.
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.
