A:Answerthe bags have a fabric feel to them - the part # is AHLR-2 and you can check it at atrix.com
the vacuum cleaner is the best I have owned for a small vac in my whole life - the suction is so strong that if I do an area rug I have to turn the pressure to its lowest setting (adjustable suction) - I highly recommend it and it is so cheap!
A:AnswerIt's very light weight and portable. I don't have stairs but I'm sure it will work fine. It has really strong suction power for a compact vacuum! The cord is not as long as I would like but I use a heavy duty extension cord so I don't have to keep unplugging it and look for another outlet. I love this little machine.
A:AnswerIt has a small pivoting caster wheel near the front that makes it easy to maneuver on smooth floors. I’ve never used it on a deep pile carpet so I cannot say how effective it would be.
A:AnswerThis would work on concrete floors. Several of the attachments are all plastic and will not scrape. It has a retractable cord and it comes with a bag installed.
