How we check robotic vacuums
Our technique for evaluating robotic vacuums is easy, but grueling. There are two kinds of assessments 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 accountable 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 explicit robotic vacuum we check.
As robots transfer by way of the room whereas cleansing, a digicam overhead captures a long-exposure picture of your complete room in low gentle. 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 are able to additionally see areas of the ground the place the vacuum could have missed or gotten caught. You’ll be able to see the navigation outcomes of all of the robotic vacuums in our check group within the gallery beneath.
The second sort of check reveals precisely how a lot bodily particles a vacuum is ready to choose up off of the ground. To imitate dust of small particle dimension, we use a mix 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 kinds 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 device 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, sort of particles, plus every vacuum’s nozzle width.
We conduct three cleansing runs (at minimal) on every flooring sort. We additionally carry out cleansing assessments with sand and rice individually. That involves at the least 18 assessments 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 proportion of particles pickup for each cleansing run and the common quantity of soil a machine manages to take away. Moreover we run anecdotal (visible) pet hair assessments 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 by way of their paces is not as difficult as testing a robotic vacuum cleaner, nevertheless it nonetheless takes plenty of time and cautious effort to search out the perfect cordless vacuum. We run every vacuum in a straight line throughout three totally different surfaces (hardwood, low-pile carpet, midpile carpet). On all three check beds, the check space is similar size (30.25 inches).
Similar to in robotic assessments, 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 sort, 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 sort. We additionally check suction energy with sand and rice individually. That involves at the least 18 assessments per vacuum. We weigh the vacuum’s mud bin each earlier than and after every run.
From there we are able to calculate the proportion of dust and particles pickup for each run and the common quantity of soil a vacuum manages to take away. Moreover, we run anecdotal (visible) pet hair assessments for every vacuum, on all three flooring varieties to assist us choose the perfect cordless vacuum.
