I just opened this little Shark and my first test was our stairs. We have 3 large dogs and 5 cats and I was amazed at how well it cleaned the stair carpet. I agree with a couple of reviews about the end of the roller brush being a little thick for the crevices on the stair, but I learned a trick from my previous hand vac. Get a wire pet brush from your local dollar store and quickly scrub the crevice at the base of each step. Use the vac to suck the hair off the brush and finish the step, it only takes a second and works great. I did our stairs in about 10 minutes where normally it too around 20 ore more. Ny only previous experience is with my Black&Decker 19.5 volt, which will suck paint of the wall, but without any type of agitator is useless for pet hair on carpet or fabric.

Another tip is to buy a cheap little waste basket to keep handy by the stairs or carry a grocery bag with you while you vacuum. Like all small hand vacs the bust bin is on the small side.Get more detail about Shark SV736K 15.6-Volt Cordless Handheld Vacuum Cleaner with Motorized Brush, Colors Vary.
