Lightweight vacuum for carpeted stairs...?

I need a lightweight and/or cordless vacuum for the carpeted stairs in my house. It's a high traffic area and we have a dog that sheds and sheds and sheds. I'm kind of weary of some of them, because I just don't know that they'll clean very well. Also, I have terrible allergies and really need it to get the dirt and dog hair up. Has anyone had one that they really like and has done a great job?

The best vacuum I have ever used is a shop vac with a small brush attachment on the end of the hose. Unfortunately they are not exactly lightweight nor portable.

For quick touch-ups, try a lint roller. Really picks up the hair and small particles.

A lot of full-size vacuum cleaners have a power attachment that is made for stairs and small spaces. It vacuums and has a beater bar. You get the benefit of a full-powered vacuum cleaner, and you only have to invest in one machine. The one I had worked really well, but I don't remember the brand it was.

I use a Dirt Devil. Bought it just for the steps and my truck. It works great and weighs maybe 5 pounds. Royal makes it and they're not expensive. I tried 2 different cordless and they just didn't have the staying time or the power to do the job. Finally settled on this a few years ago.Plus this one comes with a handy hanger. I keep mine in the cellar way hall.
