Recommended View more details.

We recommend robot vacuums that score at least 70% overall so long as they also score at least 46% for carpet.

CHOICE Expert Rating View more details.

For models tested before 2023, this overall score is made up of performance only including hard floor dirt pick-up (40%), dirt removal from carpet (30%), cleaning corners and edges (15%) and pet hair removal (15%). From 2023 onwards, ease of use makes up 10% of the CHOICE Expert Rating and performance scores make up 90%.

Hard floor dirt pick-up performance score View more details.

We scatter a measured amount of sand evenly over a vinyl floor area and let the robot run for 25 minutes, or until the vacuum completes its cleaning cycle, measuring the dirt pick-up at intervals throughout. Objects like chairs and benches are placed around the room to make the set-up look similar to a home.

Dirt removal from carpet score View more details.

We sprinkle sand evenly into a section of carpet and let the robot run for a set period of time on the carpeted area. The sand collected is weighed and recorded.

Cleaning corners and edges score View more details.

Sand is spread into a right-angled corner, and the robot vacuum cleaners are assessed to see how close to the corner each one is able to pick up dirt.

Pet hair removal score View more details.

We embed cat hair into the carpet and allow the robot vacuum cleaner to run for six minutes. We rate the vacs based on how much cat hair is left behind after the test.

Ease of use score View more details.

Available for all models tested from 2023 onwards. Includes ease of connecting and using the app, and ease of emptying the bin (or the self-emptying dock, if it has this feature).

Ease of Wi-Fi connection View more details.

How easy it is to connect the the app to the robot and your home Wi-Fi network.

App score View more details.

Ease of using the app and its features.

Ease of emptying score View more details.

How easy is it to empty the bin? Models with a self-cleaning dock tend to score higher for this.

Overall mopping score View more details.

This test was introduced in September 2023 so not all models will have a score. We test ease of filling and cleaning the tank, using the settings and attaching the mop bin and pad. For performance we place stains on a hard floor and rate how well the vacuum removes them. We penalise models that stain carpet on their way around. Since not all robot vacuums can mop, we don't include this score in the CHOICE Expert Rating.

Mopping performance score View more details.

This test was introduced in September 2023 so not all models will have a score. We test stain removal performance and assess how much water is left on the floor.

Mopping ease of use score View more details.

This test was introduced in September 2023 so not all models will have a score. We test how easy it is to attach the mop pads and bin, fill the water tank, use the settings and controls, and clean the water tank.

Noise measured on carpet/hard floor (dBA) View more details.

Noise is measured at two metres. Even though most models produce similar sound readings, some emit a high-pitched whistle or various tones and alerts (even music!) that some people may find irritating.

Battery life, measured (min) View more details.

How long the battery will last for without a charge, measured in minutes. We've noticed some models that seem to have a 'cleaning' mode and 'searching for home' mode. In these cases we measure battery life until the motor stops running (i.e cleaning has stopped).

Does it hit objects? View more details.

Robot vacuums bump objects as they find their way around, but good sensors and cameras can help them avoid frequent and/or heavy collisions.

Shop Ethical rating View more details.

Shop Ethical rates the environmental and social impact of the company (not the product) using independent sources. This rating is not included in our total score. The rating ranks from A (highest) to F (lowest); N/A means there is no rating for that company.

D
Reliability score View more details.

We use the information received from members who took part in our reliability survey to rate the most popular brands for reliability. na means no/not enough responses were received for this brand.

Satisfaction score View more details.

In our reliability survey we asked owners what they think of their robot vacuum cleaner and got them to rate their vacuum ranging from excellent to terrible. We don't have enough responses from most brands.

Country of origin View more details.

The model has a claimed country of origin somewhere on it, but this ought to be taken with a grain of salt given it's rare that all the materials for a product come from the one country.
