This is an excellent accessory kit. I upgraded to the 2.5" hose and attachments because my small hose would get clogged every easily. Now with the bigger hose nothing gets clogged anymore. I'm surprised at the increased amount of suction I'm getting with the bigger hose. You have to be careful not to suck up your tools because they will easily fit down the hose. If you have a powerful shop vac that is still using the 1 1/4" hose, you are missing out on a lot of power.
