Query: Great Product!!

My 3 grandkids played with one of these vacuum cleaners at a kid's birthday party and we couldn't even drag them away for cake!! The 4 and 5 year old girls and the 2 year old boy all loved it. The party hostess said both her daughters loved it and the rechargeable batteries were great. It was easy for the kids to use, and we had to empty the dirt collection cup a few times while we were there from so much use. It really works so the kids feel like they're truly helping. Now I ordered one for Grammy's house and one for Mommy's house! Oh boy, help around the house!!!
