I’ve got a Ridgid shop vac with a 2.5” hose. I’m trying to connect it to my new Bosch ROS65VC-6

The sander comes with an adapter that fits either 1-1/4-In. and 1-1/2-In. hoses.

Am I better off using my existing hose (it’s not terribly flexible) and an adapter or going with a different hose all together? The 2.5” hose works great with my router table, so there’s a tradeoff either way. Looking for input from anyone with a similar setup.

I have a Bosch 3725 which I think is a predecessor to the one you have. I run it with the 1 1/4” ID hose and found it to be about as good a compromise as you can get. You still have plenty of vacuum, and the hose is small/flexible/not obtrusive enough to work well while you’re moving the sander around. At one point I tried a Bosch 1” hose they sell for it and found it so lacking in air movement (suction) and a really annoying high pitched whistle I threw it away after one use. I could never get the 2 1/2” hose adapted to the sander, though if I had it would no doubt be unusable just due to the size. Besides, at least with mine, you can have too much suction. Even with the 1 1/4” hose I need to throttle back the vac a little. At first I just vented the hose at a connector. Eventually I bought a vac with variable speed. The reason I need to reduce the suction was that it was actually pulling the sander into the wood with a lot of force. this was not only putting a load on the sander, but it will overheat and ruin your H&L pads. So my advice would be to get the 1 1/4” hose, and check whether the sander is being overloaded (they may have changed the design from my model).

You’ll be much happier with a smaller hose 1 1/4” – 1 1/2” and this adaptor: Bosch VAC024

Your sander might have come with one.

I swap between 2.5” and 27mm hoses on festool CT26 all the time for various tasks, it’s not that big of a deal.

Yes, the sander came with the adapter. And to Fred’s point, the adapter seems to have a swivel that allows you to adjust the suction accordingly.

It looks like Home Depot sells a 1 1/2” upgraded hose for my vac that should work well. I’ll try that. Thanks!

I have to second this one and the duck tape as well!
