Robotic Vacuum Cleaner Energy Consumption Levels


There are many advantages to having a Robotic Vacuum Cleaner in your home and reducing your energy usage and consumption is one of them. As technology evolves, Robot vacuum cleaners are programmed now to work and clean on certain specific rooms, avoid no go areas, mapping out the room perimeters, use drop sensing technology to avoid falling downstairs and to consume as little energy as possible.

Research has shown that your Robotic Vacuum cleaners can use 14 to 15 times less energy than your manual Vacuum cleaner so you can assume straight away that it is an energy saving cleaning appliance.

Normal traditional vacuum cleaners can use 1.4kWh power per hour whereas your Robotic Vacuum cleaner when charging would only use between 50 to 100 watts over the 3 hour charging period. When the Robot vacuum is fully recharged then, it can generally give you 45 minutes to 1 hour of cleaning. So as you can see there is a big difference between the energy usage of a traditional vacuum cleaner to that of a Robotic vacuum cleaner.

Level of Cleaning

One thing to note though is the fact that certain models of Robotic Vacuum cleaners don’t offer the same level of deep cleaning that you can get from a traditional manual vacuum cleaner. Plus, it won’t get into some of the harder to reach areas of your rooms so you can find yourself having to use the traditional vacuum cleaner in tandem with your Robotic vacuum cleaner, so your energy usage is increased again – instead of using 1 appliance you are now using 2 appliances to vacuum clean your home. In addition, the Robotic vacuum cleaner cannot cover the upholstery, stairs or spillages on sofas so you will need to keep this mind when taking on the larger expense of a Robotic vacuum cleaner.

Cost of Power

The average UK electricity price per kWh was 18p-20p per kWh in 2021 however it will be around 34p per kWh in late 2022 depending on the rate and tariff you are on. Let’s compare the traditional vacuum cleaner to the Robotic vacuum cleaner based on 1 hours work during the week

  • Traditional Vacuum cleaner for 1 hour use per week uses 1.4kWh x 34p – this will cost you around 48p
  • Robotic Vacuum cleaner for 1 hour use per week uses 0.1kWh x 34p – this will cost you around 3p

To keep the electricity costs to a minimum on the Robotic vacuum cleaner, you should set it up that it only works maybe 1 to 2 days per week instead of having it working each day of the week or month. This can be done easily by adjusting the appliance settings and some brands will allow the settings to be controlled via your smart device.

Higher Powered Robotic Vacuum Cleaners

As you would expect the higher-powered Robotic vacuum cleaners that give superior suction and cleaning results will consume higher levels of energy which in turn requires more electricity. You can choose lower powered Robot Vacuum cleaners 15 to 20W, medium powered Robot Vacuum cleaners 30 to 35W and the higher-powered models of 90 to 120W. The lower powered vacuums are really only for light dusting cleaning work while the more powerful ones can deep clean carpets and provide superior cleaning for heavy duty work and debris.
