Controls
The control method provided for in the design of the machine.
Note that for models with simple manual control (when the user holds the handle and thus directs the machine), as well as for robots controlled exclusively from their own built-in panel, this parameter is not indicated; it is given only for units with more advanced options. For traditional harvesting machines, this may be
the steering ; in turn, robots (see “Type”) can be controlled from
a remote control and/or
smartphone. Here's a more detailed description of these options:
- Steering. Control using a steering wheel or steering wheel. Used in heavy productive self-propelled equipment (see below), which would be difficult to deploy manually. Many of these models even have an operator seat and are essentially mini harvesting tractors of sorts. However, there are also units for which the operator must walk while working - they are somewhat less convenient to use, but are more compact, lightweight and inexpensive.
- Remote control. Control using a separate remote control supplied in the kit. More often, communication is carried out via an infrared channel - similar to remote controls for televisions, air conditioners, etc.; however, other options are possible. In general, the functionality of such control is quite limited compared to another option used in robots - control from a smartpho
...ne (see below): from the remote control, as a rule, only a selection of preset operating programs, simple settings, and in some models - also direct motion control. On the other hand, such control is relatively inexpensive, and for most cases it is more than enough.
- From a smartphone. Control the robot from a smartphone or other similar gadget (for example, a tablet) with a special application installed on it; Communication is usually carried out via Bluetooth. This method turns out to be much more convenient and visual than using a remote control: in particular, the application can implement many additional functions that are not available with a traditional remote control (cartography with manual routing on a map of the room, scheduled cleaning, etc.). On the other hand, supporting such control affects the overall cost of the unit; and in the absence of a suitable control gadget, the robot becomes completely useless. Therefore, this option is rarely found in its pure form - much more often the ability to work with a smartphone is provided simultaneously with the remote control (see below for more details).
— Remote control / from a smartphone. Devices that support both control methods described above. This option is as versatile as possible: when working with basic functions, you can get by with the remote control, and for advanced settings, use an external gadget. At the same time, the remote control is initially included in the delivery package, thanks to which the unit can be used without a smartphone - for example, if a suitable smartphone is not on the household, or if you do not want to bother with installing and configuring the application.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.
