The Shark IF2** series v The Gtech AirRam 2
Design and approach
The overall purpose was to undertake a test of two cordless vacuum cleaners, the Gtech AirRam 2 and the Shark IF2** series, to establish which has the most suction power at the nozzle when run in the mode which offers the consumer the longest runtime.
It was ascertained that the testing methodology would be the IEC 62885-2
IBR, a UK product testing house, were engaged to carry out the tests. Three new samples of the Gtech AirRam 2 and three new samples of the Shark IF250 were sent to IBR for testing.
Between 11th and 12th of July 2017, IBR carried out the test IEC 62885-2 on all three Gtech AirRam 2s and on all three Shark IF250s. The test was run three times on each sample, giving a total of nine runs on both the Gtech AirRam 2 and the Shark IF250.
Based on the testing carried out above it was found that the average AirWatts (AW) of suction power delivered by each unit at the nozzle was as follows:
• Gtech AirRam 2 overall average 5.25AW
• Shark overall average 25.91AW
*The hand vac part of the IF2** series are technically identical, these test currently cover IF200UK, IF200UKT, IF250UK and the IF250UKT
