Comparison Xiaomi Hutt DDC55 vs HOBOT 388 Ultrasonic

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.

Rated power of the engine installed in the car.

Most often, this paragraph gives the total engine power. However, in units with a suction function - for example, scrubber dryers (see "Type") - only the power transmitted to the brushes can be indicated here. In such cases, the total power can be determined by summing the motor power and the suction power (see below). These details should be clarified separately. We also note that in self-propelled models (see above), part of the engine power is spent on moving the unit, which is why the useful power of such machines is lower than that of similar non-self-propelled equipment. In light of this, only models with the same movement format can be directly compared by this indicator - only self-propelled or only non-self-propelled.

Overall, higher motor power results in higher efficiency and productivity. However, there is no strict dependence here, and devices with similar engine characteristics can differ markedly in practical characteristics - productivity, working width, etc. So when choosing, it makes sense to pay attention first of all to these characteristics - especially since for some units (in particular, many robots) the engine power may not be supplied at all. As for specific power values, in the most modest equipment - in particular, household scrubber dryers - it does not exceed 600 W ; 600 – 1200 W can be called average, 1200 – 1800 W is above average, and in powerful heavy units there are even more respectable values.

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).

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.

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.

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.
