HI. I DO NOT HAVE ARTHRITIS SO I CAN NOT ATTEST TO HOW THIS WOULD WORK FOR YOUR MOM. I BORROWED A BAGLESS SWEEPER WHEN MY KIRBY BROKE DOWN. I WILL NEVER OWN A BAGLESS SWEEPER!!!!!!!! I HAD TO EMPTY IT SEVERAL TIMES BECAUSE THE DOG HAIR KEPT PLUGGING UP THE SUCTION. IT SAYS IT IS BETTER FOR ALLERGIES BECAUSE YOU DO NOT HAVE THE BAG BUT I DON'T SEE HOW. EVERY TIME I EMPTIED IT THE DUST FLEW EVERYWHERE! YUCK!!!!
MAYBE IF YOU DIDN'T HAVE A PET YOU WOULDN'T HAVE TO EMPTY IT AS OFTEN. BUT I THOUGHT IT WAS VERY INCONVIENENT TO CONSTANTLY HAVE TO STOP SWEEPING TO GO EMPTY THE CANISTER. I HOPE MAYBE SOMEONE ELSE HAS HAD BETTER LUCK WITH THESE SWEEPERS. TAKE CARE.
