I own my on Cleaning company. I have small houses that take me 2 hours and big houses that take me 6 hours. I have owned 3 vacuums since I stared my business. This back pack canister vacuum saves me so much time. It has vacuumed up things that all my other vacuums have left behind. I actually takes up less space in my car and is lighter weight than any of my other vacuums. The carpet head is a little heavy but it feels so durable. The 50ft power cord is wonderful. The floor attachment is short enough to fit in small places but is wide enough that is has good floor coverage with every pass. My old vacuum (not a Prolux) I would have to clean hair and dirt off it multiple times in a room, but with this vacuum maybe twice though out the entire house. I can’t think of anything I would change about it.
My wife is very happy with light weight and the suctioning power.
My dad and I ran a vacuum repair shop when I was in High school and Kirby cleaners were our favorite. Right now I'm saving up to get another one. You can't beat the power of a Kirby. And they last forever if properly cleaned and care for.
The head fit right on my vacuum and has been working great.
