Erbauer ERO400 125mm Electric Random Orbital Sander 220-240V (581FX)

Hello MaHug, Thank you for your enquiry. The main difference between an orbital and detail sander is that a detail sander can fit into any internal corners. However, if that isn't a requirement an orbital sander is excellent for larger flat surfaces. Hope that helps. Thank you for using Q&A

Hello, This sander can be used on stair, but whether it's the most suitable choice for your stairs depends on what type of sanding work you wanting to do. If its just a smoothing, clean up or keying you're planning this should be fine. However, if you are looking to remove layers of paint/stain etc then this sander would not be the best choice (it would take to a very long time and you would use lots and lots of sanding sheets). If you're looking to remove layers of paint etc on stair then it might be a better idea to either opt for a decent belt sander or try using a paint stripper solution and then scrape and scrub the paint off. It may be a good idea to consult with a tradesperson as they can better advise what tool would suit your particular needs. Thanks for using Q&A

Hello, The instruction manual for this tool states that a Ø35mm hose should be attached to the dust extraction adaptor. Thanks for using Q&A.
