How we check robotic vacuums
Our technique for evaluating robotic vacuums is easy, but grueling. There are two forms of checks we run. The primary trial is to determine how nicely a robotic covers the ground whereas it is cleansing. We constructed an industry-standard testing room as specified by the Worldwide Electrotechnical Fee, only for this function. The IEC is a global requirements physique liable for managing robotic vacuum testing procedures, amongst different issues, for vacuum producers.
Inside this room are objects designed to simulate typical obstacles a robotic vac encounters for navigation because it cleans. These obstacles embrace wall edges, desk and chair legs, couches and different furnishings, and so forth, plus naked tile and hardwood flooring, in addition to carpet. We mount LED lights to the highest of every vacuum cleaner. The size of the lights correspond to the measured nozzle width of every specific robotic vacuum we check.
As robots transfer via the room whereas cleansing, a digital camera overhead captures a long-exposure picture of all the room in low mild. That photograph will then have a light-weight path, created by the LEDs, that reveals the precise areas the place the robotic traveled (and its nozzle place) throughout its runtime. We will additionally see areas of the ground the place the vacuum could have missed or gotten caught. You possibly can see the navigation outcomes of all of the robotic vacuums in our check group within the gallery under.
The second kind of check reveals precisely how a lot bodily particles a vacuum is ready to choose up off of the ground. To imitate filth of small particle dimension, we use a combination of play-sand and landscaping sand. For greater particle soil, we use grains of raw black rice. Robots then run in straight line mode throughout three forms of flooring (low-pile carpet, medium-pile carpet and hardwood naked flooring).
We management for the precise nozzle width of every vacuum, too. We constructed an adjustable instrument to soil our check flooring. It lets us lay down a strip of a exact space of soil to match the nozzle dimensions for each robotic. The mass of soil is not chosen at random both. We measure a proportional quantity that is associated to the flooring materials, kind of particles, plus every vacuum’s nozzle width.
We conduct three cleansing runs (at minimal) on every flooring kind. We additionally carry out cleansing checks with sand and rice individually. That involves a minimum of 18 checks per robotic vac. We weigh the robotic’s mud bin each earlier than and after every run. From there we are able to calculate the share of particles pickup for each cleansing run and the typical quantity of soil a machine manages to take away. Moreover we run anecdotal (visible) pet hair checks for every robotic, on all three flooring varieties.
Our rice-based, medium-size particle check did not present sufficient differentiation between every cleaner, which says they’ll all deal with bigger particles with out hassle. For fur elimination for pet house owners, we judged anecdotally.
How we check cordless vacuums
Placing cordless vacuums via their paces is not as sophisticated as testing a robotic vacuum cleaner, however it nonetheless takes numerous time and cautious effort to search out the very best cordless vacuum. We run every vacuum in a straight line throughout three completely different surfaces (hardwood, low-pile carpet, midpile carpet). On all three check beds, the check space is identical size (30.25 inches).
Identical to in robotic checks, the width of the check mattress is proportional to the vacuum’s nozzle width. We measure this width ourselves. We additionally use nozzle width, plus the flooring kind, to calculate the soil density for every check, per IEC pointers. We use the identical soil varieties right here as nicely; sand, rice and pet hair. We carry out three runs (at minimal) on every flooring kind. We additionally check suction energy with sand and rice individually. That involves a minimum of 18 checks per vacuum. We weigh the vacuum’s mud bin each earlier than and after every run.
From there we are able to calculate the share of filth and particles pickup for each run and the typical quantity of soil a vacuum manages to take away. Moreover, we run anecdotal (visible) pet hair checks for every vacuum, on all three flooring varieties to assist us choose the very best cordless vacuum.
