Seen them on TV... They can even pick up crushed cans, etc. Maybe they will pick up small toys like Leggos? No power, you just push and it has big sweeping brushes in the front..
You can probably use it in the house if you have kids.. lol.
*L* .. that would send Carly into a complete melt down .. she already goes screaming from the room when I use the one I have
All my kids did that when they were little .. never could understand why it freaked them out so .. but it did come in handy when they were being really really bad *L*
