-
Pick-up dirt from hard floor score
View more details.
We test how effectively the stick vac picks up a variety of materials (cornflakes, potting mix and flour) from hard floor.
-
Ease of use score
View more details.
We measure how easy it is to manoeuvre the cleaner; empty and clean the dirt receptacle; operate the controls; and use and store the supplied accessories.
-
Pet hair removal score
View more details.
To test pet hair removal, we embed cat hair in the carpet and, as with the dirt pick-up test, vacuum it to a set pattern and speed. We rate the results based on how much cat hair is left behind after the test. Where supplied, the turbo brush or power head is used for this test; otherwise, we use the standard cleaning head. Pet hair for testing supplied by Woof Cat & Dog Grooming, Bondi, NSW.
-
Thorough carpet clean score
View more details.
We embed sand evenly into a section of carpet, then vacuum. The sand is weighed and recorded, which is done twice for each model with the results averaged. A thorough test is 10 passes.
-
Quick clean score
View more details.
We embed sand evenly into a section of carpet, then vacuum. The sand is weighed and recorded, which is done twice for each model with the results averaged. A quick test is 4 passes.
-
Car cleaning score
View more details.
For those models that separate from the stick into a handheld vacuum, we disperse pebbles and sand throughout the front and rear floor of a car and evaluate how well they pick up these materials. This is not counted towards the final score, as not all vacs are 2-in-1 products.
-
Cleaning corners and edges
View more details.
Sand is spread into a right-angled corner and vacuumed to see how far into the corner each cleaner is able to pick up dirt, using the standard cleaning head.
-
Noise (dBA)
View more details.
Noise is measured at the user's position at maximum power setting. Some models emit a high-pitched whistle that can be irritating, even though they may not be louder than others. For comparison, a typical conversation is carried out at about 60dB, while city traffic is measured at around 80dB.
-
Running time (min)
View more details.
How long the vacuum battery lasted in our tests. Measured under load (on carpet) with the brush head on, and at full power.
-
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.
- C
-
Brand reliability score

We asked members in our 2020 reliability survey to rate their stick vacuum brands, and state whether they had run into any problems in the last 12 months. Not all brands have a reliability figure as we require a minimum of 50 responses per brand.
-
Brand satisfaction score
View more details.
We asked members in our 2020 reliability survey to tell us what they thought of the stick vacuum brands they own, rating them from excellent to terrible. We use this information to give each brand an owner satisfaction rating. Not all brands have a satisfaction figure as we require a minimum of 50 responses per brand.
