The usual vacuum maintenance and usage requirements can be expected with backpack vacuums. Filters need to be removed and replaced or rinsed occasionally, and collection bags need to be emptied or replaced. Because of the multi-stage filtration systems, users should expect multiple filters to contend with at times. While the maintenance required isn’t excessive, it can’t be ignored. These high-quality filtration systems are only as good as their filters, so proper maintenance is key. Brushes and other attachments may need to be cleaned and cleared of hair and debris that will accumulate over time.
