Each Samba School is allowed to bring from 6 to 8 floats to the
Samba Parade. They play a key role in the performance of schools,
and with judges assigned specifically to analyze them. Floats can
be really huge, sometimes 10 meters high (about 30 feet). If they
are too wide or long, though, they may have problems with the
sharp turn from the concentration to the entrance of the samba
runway. Some floats have moving parts, and most are quite
sophisticated. They may be motorized, or pushed by men from the
community.
