By Lisa Ehrhardt
Floor cleaning is one of those recurring tasks every household faces. It takes not just time and energy, but the right tools to work efficiently and sustainably. A good vacuum cleaner or robot vacuum can make a real difference in everyday life — removing dirt and dust while also helping to minimise environmental impact.
In this article, we’ve rounded up the best sustainable vacuum cleaners and robot vacuums — the ones that won us over with innovative technology, energy efficiency and eco-friendly materials. Here’s how to keep your home spotless while doing your part for the environment.
Dreame – X40 Ultra Complete Robot Vacuum
The Dreame robot vacuum offers virtually limitless reach and thorough cleaning for any household. Thanks to its innovative MopExtend™ RoboSwing technology, it effortlessly reaches even hard-to-access spots, and its powerful suction lifts stubborn dirt with ease. An extendable side brush and the ability to lift the mop pads at the base station also make carpeted areas fair game.
The robot features automatic mop-pad cleaning with 70°C hot water for a genuinely hygienic clean. Smart dirt detection navigates the home with precision, focusing extra attention where it’s needed most. And the fully automatic suction station empties the dust container on its own, making manual intervention largely a thing of the past.
Dreame takes sustainability seriously, investing 12 percent of its annual revenue into researching and developing eco-friendly technologies — investments that have already led to smarter, more energy-efficient cleaning products. The robot vacuum is available through Dreame’s online shop.

Vorwerk – Kobold VR7 Robot Vacuum with RB7 Suction Station
Vorwerk’s Kobold VR7 robot vacuum took top honours in Stiftung Warentest’s rankings, winning praise for its D-shaped design that reaches cleanly into corners. Its extra-wide main and side brushes lift dirt from hard floors and carpets alike, while intelligent navigation keeps the cleaning routine running smoothly. A low profile lets it glide effortlessly under cabinets and beds.
In ECO mode, the VR7 vacuums for up to two hours on a single charge, cutting energy use while staying quiet. Its long-life battery retains 70 percent capacity even after 800 charge cycles, and parts of the VR7 are made from recycled materials — a genuinely sustainable choice.
The RB7 suction station empties the robot’s dirt container automatically and hygienically, meaning the station itself needs emptying only once every 60 days — a real boon for allergy sufferers. The VR7 maps floor plans quickly and navigates the home with precision thanks to its sensor technology, detecting obstacles, stopping short of stairs, and clearing rug edges and door thresholds up to 1.5 centimetres high. The MyKobold app lets you steer the robot remotely, set cleaning zones and check cleaning summaries, plus it offers step-by-step guides, scheduling and helpful tips. The robot vacuum is available through Vorwerk’s online shop.

Ecovacs – DEEBOT X2 OMNI
The Ecovacs robot vacuum pairs innovative technology with sustainability for an exceptional cleaning solution. Its square design, 8,000Pa suction power and OZMO Turbo 2.0 rotating mop system deliver a thorough clean tailored to everyday demands. Advanced AIVI 3D 2.0 and TrueMapping 3.0 technologies let the DEEBOT X2 OMNI navigate with precision, dodge obstacles and build detailed maps of your home. A smart mop-lifting system and roller brush boost efficiency, achieving near-total coverage of 99.77 percent per unit area. Its compact design lets the DEEBOT X2 OMNI slip into tight spaces and glide effortlessly under furniture to reach the spots other cleaners miss, while its OMNI station tucks neatly into the home without taking up much room.
Beyond its cleaning performance, Ecovacs is committed to sustainability and social responsibility. Rooftop solar installations at its facilities cover up to a third of total electricity needs, meaningfully optimising its energy mix. The robot vacuum is available through Ecovacs’ online shop.

iRobot – Roomba Combo® j7+ Vacuum and Mop Robot
The Roomba Combo® j7+ from iRobot sets a new bar for sustainable floor care with its innovative 2-in-1 function.

Wi-Fi connected, it vacuums and mops simultaneously, powered by iRobot’s capable OS.
This model stands out for its advanced obstacle detection and avoidance technology, navigating around obstacles with ease to make sure nothing gets damaged along the way. Its four-stage cleaning system includes a corner and edge brush, two rubber brushes suited to any floor type, strong suction, and a distinctive mopping system.

Kärcher – RCV 5
Kärcher’s smart cleaning robot delivers a systematic, thorough clean for hard floors and low-pile carpets. Equipped with a rotating brush, a side brush for edges and a powerful blower, it reliably lifts dry dirt and channels it into its built-in dirt container. An ultrasonic sensor detects carpets and triggers an Auto-Boost function that maximises suction for a deeper clean. It handles both vacuuming and wet mopping, automatically avoiding carpets in mop mode to keep them dry.
Controlled via app, the robot explores its surroundings, builds a detailed map of the space using LiDAR technology, and allows for customised cleaning settings in each area. It detects flat obstacles like cables or shoes and navigates skilfully around them, while additional sensors prevent falls on stairs. For wet cleaning, the RCV 5 is fitted with a mopping unit and a microfibre cloth, and its fresh-water tank is filled accordingly — the robot can then run dry cleaning, wet cleaning, or combine both modes.
Kärcher is a family business deeply committed to sustainability. Since 2021, all Kärcher factories worldwide have run on green electricity, with a target of cutting CO2 output by 21 percent by 2025. The company focuses on reducing plastics and using renewable raw materials — commitments that earned it the German Sustainability Award in 2022. The robot vacuum is available online through Kärcher’s online shop.

The AEG LX9 bagless vacuum offers an innovative approach to effortless, efficient floor care. Equipped with a fully sealed PureFlow system, the LX9 delivers outstanding performance and advanced filtration. Its revolutionary 3D filter system keeps suction power consistently strong, with no notable loss of performance over time. Intuitive dust-container emptying and an easily accessible filter make cleaning the vacuum itself quick and simple.
Another highlight of the LX9 is its permanent filter, which is not only practical and highly effective but never needs replacing — saving money and sparing the environment. Extra-large, surface-friendly XL soft wheels make manoeuvring easy and precise, letting the LX9 glide smoothly through the home. It’s a powerful, sustainable cleaning solution built around usability and efficiency.
AEG places great weight on sustainability and resource conservation.
