Comparison Makita DUB185RT vs Makita UB101DZ

The highest speed of the air stream given out by the vacuum cleaner. The higher this parameter, the stronger the thrust provided by the device, and the more efficiently it is able to pull or blow out debris particles from cracks and other hard-to-reach places (of course, if there is an appropriate operating mode — see above). At the same time, in most modern models, this figure exceeds 150 km/h — this is more than enough for work of small and medium complexity. Therefore, paying attention to a high flow rate makes sense only when choosing a powerful model for working in difficult conditions; we note that in the most “high-speed” vacuum cleaners, the indicators can exceed 400 km/h.

Performance of the garden vacuum cleaner when blowing (see "Operating mode").

This parameter determines the amount of air that the device distills through itself in a certain time. It should be noted that it depends not only on the speed of this air, but also on other parameters — for example, the diameter of the pipe. Therefore, two models with the same performance can noticeably differ in speed, and vice versa. You also need to keep in mind that the efficiency of "purging" bottlenecks with stuck debris does not depend on performance, but on the flow rate. On the other hand, good performance makes it easier to work on large areas, as allows you to simultaneously cover a large area with a jet of air.

Most modern garden vacuum cleaners in blowing mode provide up to 15 m / min; higher rates are typical mainly for professional models.

The highest speed at which the vacuum cleaner engine is able to operate in normal mode.

Theoretically, faster motors are capable of delivering more solid performance; however, in fact, these characteristics depend on so many different design features that the engine speed is practically lost against the background of these features. Therefore, this moment, in fact, is purely reference (and partly promotional — impressive rpm numbers can at first glance give the impression of high power and performance; but this impression is often deceptive).

Complete Battery Set in garden blowers-vacuums shows how many batteries are included in the set and how ready the tool is to work "out of the box." One battery is the basic option for small areas and occasional cleaning when the minimal budget is important, but the working time is limited. Two batteries already allow you to comfortably maintain the yard and garden paths: while you use one battery, the other can be recharged or kept as a backup. Four batteries are almost always found in models that are designed to operate with two batteries at once: one pair is in the tool simultaneously for maximum power and extended operation, and the second pair is charged and ready to quickly replace the first without any pauses. There are also devices without batteries and chargers, colloquially known as "body only." This option is advantageous for those who already have compatible batteries of the same platform and do not want to overpay for duplicates.

Name of the battery platform supported by the device. A unified battery platform is used to combine various power tools and garden equipment of one brand into a single line (drill, angle grinder, trimmer, etc.). Devices belonging to the same platform use interchangeable batteries and chargers. Thanks to this, for example, there is no need to choose a battery for each individual model of power tool, as one battery purchased as a spare can be used in various power tools, depending on the situation or as needed. Batteries of one platform mainly differ only in capacity.

The battery voltage for which the powered garden vacuum cleaner is designed (see "Motor type"). For a powerful unit, usually, a fairly high voltage is required.

For the user, this parameter is important if the purchased vacuum cleaner is not equipped with a battery (see "Battery included"): in order to successfully select the battery, you need to know the required voltage. If the battery is included in the kit, then this indicator has a purely reference value, and can only come in handy when looking for a spare or additional battery.

The capacity of the battery that the garden vacuum cleaner is equipped with the appropriate power supply (see "Motor type").

Capacity is essentially the amount of energy a battery can store. The more powerful the device, the more energy it needs to work and the higher the battery capacity should be so that it does not have to be charged too often. At the same time, capacious batteries have a large weight and dimensions, which significantly affects the convenience of work. Therefore, the power of battery units is relatively low — otherwise, too bulky batteries would have to be used.

To some extent, this parameter also determines the time that the vacuum cleaner is able to work without recharging. However, taking into account the fact that different models can differ markedly in power consumption, it makes sense to compare battery properties with each other only tools with very similar characteristics — and even then very approximately.

Note that the same tool can work with batteries of different capacities — it is enough that they are compatible in terms of connectors and operating voltage. Therefore, for units that are not equipped with batteries, this parameter is not indicated at all — the capacity is not critical for compatibility.

The model of the standard battery allows you to learn more about its characteristics and will also help you understand which devices it is compatible with and which one should be purchased in case of a malfunction or if there is a need to buy another similar one.

The name of the battery that is compatible with the device. It helps to buy a spare or find a suitable one in case of a breakdown of the main one.
