I starting doing remediation a year ago and purchased this hepa vacuum and have been very pleased. Yes, the attachments are not the best but you cannot beat the quality for the price with multiple filters.
I purchased these for my custodial team and they have had no complaint. I've used it myself and have had no issues with it. This vacuum cuts the time in half and performs beyond expectations. It also costs less than other back pack vacuums and exceeds the more expensive makes out there.
Love this vacuum it is bad to the bone!!!! great suction power easy to use on my stairs and everything. I use it to vacuum out my car. this is the best vacuum i have had in years!!!
There aren't enough words to complete the thought - this thing works great. I am considering purchasing the power head for carpet. Do not skip over this model easily.
It is the best vacuum cleaner I ever used, it is light, easy to use with multiple suction caps. Engine is located behind the bag. Empty your bag at half of its capacity to prolong engine life.
