This vacuum cleaner has a very strong suction power and is the highlight of the product. The backpack portion of the canister is very well set up with easy on/off switch access, an adjustable fit, and ergonomic features. The problem I have with this vacuum is the C-ring in the hose that holds the attachments to the hose. . The C-ring tends to fall out and get lost easily, without this the nozzle rings will not stay connected to the suction hose. I've stretched the C-ring with some success, I also noted its size in case I couldn't find it the next time I vacuumed.
