Xiaomi vacuum cleaners are no longer a luxury, they have become an integral part of the smart home, saving time on cleaning. But along with the convenience, the question arises: how much electricity does this assistant consume? In the face of rising electricity tariffs, this is not an idle curiosity, but a real expense that you want to control.
In this article, we will look at how to calculate the power consumption of Xiaomi robot vacuum cleaners (including the Dreame and Viomi sub-brands), compare models by efficiency, find out which modes of operation are most βvoraciousβ, and give practical tips to reduce costs, learn whether to turn off the device from the socket, how the wet cleaning function affects consumption and why some models waste energy even in standby mode.
Spoiler: Xiaomi Mi Robot Vacuum-Mop 2 Pro, in its maximum power mode, consumes as much power per month of continuous operation as a regular incandescent light bulb in 10 days of burning.
How to calculate the electricity consumption of a robot vacuum cleaner
To understand how much electricity your Xiaomi is eating, you need to consider three key parameters:
- π The power of the device (indicated in watts, watts) is a passport characteristic that the manufacturer must specify in the technical specifications. D9 maximum suction power is 3000 Pa, but the power consumption is about 50 W.
- β±οΈ Operating time β how many hours a day/week/month the vacuum cleaner is active, and it is important to consider not only cleaning, but also charging, as well as consumption in standby mode.
- π‘ The mode of operation is quiet, standard, turbo or maximum, the difference in energy consumption between them can reach a maximum of two. 3-4 once!
The formula is simple:
Consumption (kWh) = Power (kW) Γ Working hours (hours)
But the devil is in the details. For example, Xiaomi Mi Robot Vacuum-Mop P in silent cleaning mode consumes ~25 Wh, and at maximum, up to 70 In this case, in standby mode (when just stands on the base), he "pulls" about 2-3 If the vacuum cleaner is working 1 hourly (40 Wh 23 the hour is in sleep mode (3 W), then daily consumption will be:
(40 Watt Γ 1 smack) + (3 Watt Γ 23 smack) = 40 + 69 = 109 Wh-h = 0,109 kWh
In a month, it'll turn into 0,109 Γ 30 β 3,27 kWh. At the fare 5 RUB per kWh (relevant for many regions of Russia in the 2026 yearly value 16,35 Not that much, right? But that's just the tip of the iceberg.
Comparison of power consumption of popular Xiaomi models
Not all Xiaomi robot vacuum cleaners are equally voracious. We analyzed specifications and user reviews to rank models for energy efficiency. The data in the table below are for standard cleaning mode (not maximum!).
| Model | Max. suction power (Pa) | Cleaning consumption (W) | Standby consumption (W) | Approximate monthly intake (kWh)* |
|---|---|---|---|---|
| Xiaomi Mi Robot Vacuum-Mop 2 Lite | 2200 | 30-45 | 2 | 2,5-3,5 |
| Xiaomi Mi Robot Vacuum-Mop P | 2500 | 35-50 | 2,5 | 3-4,5 |
| Dreame D9 | 3000 | 45-70 | 3 | 4-6 |
| Viomi V3 | 2700 | 40-60 | 2 | 3,5-5 |
| Xiaomi Mi Robot Vacuum-Mop 2 Pro | 3000 | 50-75 | 3 | 5-7 |
*Calculation performed for daily cleaning for 1 hour in standard power mode + 23 hours in standby mode.
Note: models with wet cleaning function (for example, Viomi) V3 Mi Robot Vacuum-Mop 2 Pro) consume on 10-15% It's because the pump is running, but it's not critical, because the main appetite depends on the suction power.
β οΈ Warning: Manufacturers often specify maximum suction power (in Pascals), but do not always disclose the real power consumption in watts. D10 Plus has a suction of 4000 Pa, but its peak consumption reaches 85 W β this is almost 2 times more than the base models Xiaomi.
Hidden costs: why vacuum cleaners waste energy even when they donβt clean
Many users are surprised to find that the robot vacuum cleaner consumes electricity around the clock, even if it turns on once a week, all in the background processes, which manufacturers often do not mention:
- π Charging the battery - after cleaning, the vacuum cleaner returns to base and recharges. 100% the device goes into a charge maintenance mode (called "trikle charge"), which consumes ~1-2 Watt.
- π‘ Wi-Fi connection β if the vacuum cleaner is integrated into the smart home system (for example, via Mi Home), it periodically βwakes upβ to synchronize data. ~0,5-1 Waht to total consumption.
- π€ Self-diagnosis β some models (e.g. Dreame) Z10 Pro) every 12 the clock is checked by sensors and mechanisms, which briefly increases the consumption of 5-10 Watt.
- π Standby mode -- even when the vacuum cleaner is asleep, its motherboard and sensors remain energized (1-3 Waht, but in a month they add up.
In practice, this means that the robot vacuum cleaner consumes energy. 24/7, Even if it cleans once a week. 1S in standby mode "eats" about 2 Wh/h Γ 24 smack Γ 30 days = 1,44 KWh per month β and this is without taking into account cleaning!
π‘
If you're going on vacation for a week or more, disconnect the vacuum cleaner from the socket. ~0.5 kWh in 7 days is a waste of money.
How to reduce electricity consumption: 7 working ways
If you want to optimize your spending, here are proven methods that give you a real effect:
- Use the "Silent Cleaning" mode - it consumes on 30-40% It's less energy than turbo mode. For everyday cleaning (dust, animal hair), that's enough.
- Set up a night cleaning schedule β if you have a two-tariff meter, electricity at night is cheaper than the average. 30-50%. In the Mi Home app, this is done in the Schedule section.
- Limit cleaning areas β don't make the vacuum clean the whole apartment if only the kitchen and the hallway are contaminated. Use virtual walls or areas in the app.
- Turn off the wet cleaning function if it is not needed β the water pump adds ~10 W to total consumption.
- Clean filters and brushes β clogged elements make the engine run at increased power, increasing energy consumption on the engine. 15-20%.
- Turn off Wi-Fi if you do not use remote control β this will reduce background consumption on the Internet. ~1 Wh/h.
- Use a base with automatic dust collector cleaning (for example, Dreame). D10 Plus) β it spends energy on sucking up garbage, but allows you to run the vacuum cleaner less often for full cleaning.
Use the "Silent Cleaning" mode for daily cleaning|
Set the schedule for the night (if the two-tariff counter)|
Limit the cleaning areas in the application|
Turn off the wet cleaning if you donβt need it|
Clean filters and brushes from garbage|
Turn off Wi-Fi if you do not use remote control|
Check if the vacuum cleaner remains in standby mode without the need-->
Another life hack: if your vacuum cleaner supports voice control (for example, through Alice or Google Assistant), turn off this feature in the settings. ~0.5 W to background consumption.
Myths and truths about energy consumption of robot vacuum cleaners
There's a lot of talk about energy use, and let's look at what's true and what's fiction.
Myth 1: βA robot vacuum cleaner uses as much electricity as a regular vacuum cleaner.β
Truth: The average vertical vacuum cleaner consumes 1500-2000 Wh-oh, a robot β 30-70 Wh. Even if you take the time of operation into account, the difference is huge. For example, cleaning the Xiaomi Mi Robot during the course of the day. 1 hour = iron-indulgence 5 minute.
Myth 2: βIf you turn the vacuum cleaner on/off often, it will waste more energy.β
Truth: Modern lithium-ion batteries (which are used in robot vacuum cleaners) have no memory effect. Frequent short cleaning is more economical than one long one, because the engine does not run at maximum power.
Myth 3: βThe function of cartography greatly increases consumption.β
Truth: Laser sensors (LDS) Or cameras to build a map add everything. ~2-5 It's disproportionately small compared to the energy required to suction, but it allows you to optimize your route and reduce your cleaning time.
Myth 4: βRecharging a battery consumes more energy than cleaning itself.β
Truth: Modern chargers for robot vacuum cleaners have efficiency ~90%. That is, if the battery capacity 5200 mAh (typical for Xiaomi) is charged from the network 220B, the losses are all. ~10%. For comparison: the old βbrickβ chargers for phones had efficiency 50-60%.
Why do some models consume energy even when the power is turned off?
How much does the maintenance of a robot vacuum cleaner cost per year: real figures
Let's calculate how much it costs to operate a Xiaomi robot vacuum cleaner in monetary terms, take Mi Robot Vacuum-Mop 2 Pro for example, and the average electricity tariff in Russia in 2026 is 5.5 rubles per kWh.
| Parameter | Meaning | Calculation. | Cost (ruble/month) |
|---|---|---|---|
| Cleaning (1 h/day, 50 W) | 30 days Γ 1 hour Γ 0.05 kW | 1.5 kWh | 8,25 |
| Standby mode (23 hours/day, 3 W) | 30 Γ 23 Γ 0,003 kW | 2.07 kWh | 11,39 |
| Battery charging (1 cycle/day, 0.1 kW) | 30 Γ 0,1 kW | 3 kWh | 16,50 |
| Total. | 6.57 kWh | 36,14 |
In a year, it'll turn into ~434 rubles is the amount comparable to the cost of one filter for a vacuum cleaner:
- π If you have a two-tariff meter and the vacuum cleaner works at night, the cost will decrease by a factor of two. 30-40%.
- π Turbo-cleaning (70W) costs will rise to ~50 rubles a month.
- π If the vacuum cleaner does not clean daily, but 3 times a week, the savings will be ~20%.
By comparison, a typical 1,600-watt vacuum cleaner running 30 minutes a week consumes 1.6 kW. Γ 0.5 hours Γ 4 weeks = 3.2 kWh per month, which costs in ~17.6 rubles. That is, the robot vacuum cleaner in our example spends 2 times more, but removes 20 times more often (daily vs once a week).
π‘
A robot vacuum cleaner consumes more electricity than a conventional vacuum cleaner, but replaces manual cleaning, saving you time, and in terms of comfort and frequency of cleaning, the costs are justified.
What to do if the vacuum cleaner began to consume more than usual
If you notice that the battery is running out faster and the cleaning time is reduced, it may indicate increased power consumption.
- π Battery wear - through 2-3 The battery capacity is reduced by 30-50%, Solution: Replace the battery (cost for Xiaomi β ~2000-3000 ruble.).
- π Clog filters or brushes - the engine is running at increased power. Solution: flush the filter. HEPA and clean the main brush of the wound hair.
- π€ Firmware failure - sometimes after updating the vacuum cleaner starts to "glutch" and waste energy idle. Solution: reset the settings to factory (Settings) β Resetting in annex).
- π‘ Wi-Fi problems - if the signal is weak, the vacuum cleaner is constantly trying to reconnect, which increases background consumption.Solution: Move the router closer or use a signal repeater.
β οΈ Note: If the vacuum cleaner Xiaomi after charging works less 20 minutes (at the stated time) 60-90), It's a sign of critical battery wear, and not only is it uneconomical to continue operating in this mode, but it's also harmful to the engine, because it overheats because of frequent charging cycles.
To diagnose the problem, check the battery life in the Mi Home app (Device Status section).If it is reduced by 30% or more compared to the new device, it is time to consider replacing the battery.
