Comparison Roborock S8+ vs Roborock S8

Rated power consumed by the vacuum cleaner. In models with power adjustment (see below), the maximum value is taken into account in this case. We are talking about the characteristics of the installed motor, which is the main, and in most vacuum cleaners, the only consumer of energy.

Higher power increases suction force and improves overall cleaning efficiency. In addition, a more powerful unit is easier to equip with a capacious dust collector. On the other hand, only vacuum cleaners of the same type with the same types of dust collectors can be directly compared by this parameter (see above for both). And even in such cases, the actual suction force (see below) may be different — and it is it that determines the real efficiency. However, the total power also allows you to generally evaluate the capabilities of the vacuum cleaner, including in comparison: a 1500 W model will significantly outperform its 800 W counterpart in efficiency (although it is impossible to say exactly by how much). But what definitely depends on this indicator is energy consumption.

As for specific power values, they are largely related to the type of device. For example, handheld models, robots and uproght units have low power — less than 1500 W(and often noticeably less). Such values are quite popular among other types of vacuum cleaners (conventional, industrial, workshop, etc.), but among them there are already more solid indicators — ...href="/en/list/90/pr-1067/">1500 – 1750 W, 1750 – 2000 W and even more than 2000 W.

Docking station with dust container. Upon getting to such a stand, the robot can recharge the battery and carry out self-cleaning — unloading the collected garbage into an external container. The capacity of the station is enough for several unloadings. The convenience of this function is obvious: it allows the device to work longer without user intervention and eliminates the need to manually clean the vacuum cleaner when the dust container is full (besides, unloading garbage from the dock is usually easier than such cleaning). Unfortunately, such a feature is quite expensive. There are also upright vacuum cleaners with a similar station. In such models, the cleaning is carried out with minimal human intervention - you only need to install the vacuum cleaner in the docking station. The self-cleaning mode independently moves the debris from the dust collector of the device to the dust container of the station.
