Globally, the market size for residential robot vacuum cleaners was $3 billion in 2023. It’s expected to reach $11.6 billion by 2033 – a reflection of how they have transitioned from being optional household appliances to essential products.
So, as we settle back into our routines at the start of the year and cleaning the house gets added back to the list of things to get done daily, ask yourself: why push a vacuum cleaner around when there are robot versions that will do the work for you?
Trevor Brewer, Director at air and lifestyle technology specialists Solenco, says that the evolution of robot vacuum cleaners can be traced through five innovative generations, each with unique features and advancements. “Robot vacuum cleaners present a range of options to cater to different lifestyles, cleaning needs, and budgets. From basic models to premium ones, these devices are becoming indispensable tools in modern home maintenance.”
Here’s a quick run-down of the five kinds of robot vacuum cleaners available in South Africa:
Generation 1: Dumbots
These basic robot vacuum cleaners have no technology that enables them to ‘see’ where they are going. Instead, they simply bump their way around an area and perform a set cleaning pattern. They are ideal for smaller, less cluttered spaces, and budget-conscious consumers will appreciate that they generally come in at under R1,000.
Generation 2: Dimbots
‘Dimbots’ see the introduction of 2-D LiDAR (light detection and ranging radar) mapping along with sensors or simple cameras to work their way around obstacles. However, their efficiency is still limited in complex environments, and they are best suited to homes with open layouts. In terms of pricing, you can expect to pay less than R2,500.
Generation 3: Averagebots
Basic artificial intelligence (AI) and infrared object detection sensors, along with LiDAR, enable ‘averagebots’ to avoid obstacles better and clean more efficiently. They are able to handle different types of flooring and are suitable for a variety of home sizes. Some models connect to an app that enables you to control and schedule them remotely. Price-wise, you’re looking at up to around R7,500.
Generation 4: Brainybots
360-degree 3-D LiDAR mapping, AI, and advanced sensors combine for enhanced obstacle detection and smoother navigation. ‘Brainybot’ robot vacuum cleaners can clean large, diverse, complex environments effectively, and can adapt to different floor types. For the most part, they can be integrated with smart home platforms, and controlled via an app. Generally, you are looking at up to R15,000 for this Gen 4 technology.
Generation 5: Smartbots
A ‘smartbot’ robot vacuum cleaner offers the most comprehensive and efficient cleaning experience, and is ideal for tech-savvy users with larger homes that have varied cleaning demands. Features include high-end AI for precision cleaning, sophisticated camera systems for detailed mapping, advanced mopping functions, and self-cleaning stations. Some can even recognise and clean pet ‘oopsies’! ‘Smartbots’ integrate seamlessly with smart home ecosystems, offering voice control and sophisticated scheduling. Their price-point goes up to R29,000.
Brewer cautions that as robotic vacuums are added to our networks of smart home devices, it’s important to be aware of the increasing need for cybersecurity. “If your home network isn’t properly secured, hackers can access the data from your smart appliances and gain control of them with malicious intent. When shopping for robot vacuums, one thing to consider is if the data is being stored via an app or in the cloud.”
