<p>A pneumatic floor brush (130, 230) and a vacuum cleaner (100, 200). The pneumatic floor brush comprises a shell, a roller brush and a turbine. The shell is provided with a roller brush chamber (1) for accommodating the roller brush and a turbine chamber (2) for accommodating the turbine. The turbine drives the roller brush to rotate. A dust-containing air current (6) enters the roller brush chamber (1) through a dust sucking opening (9) provided on the shell. A clean air current (5) enters the turbine chamber (2) through an air sucking opening (8) provided on the shell. A current guiding channel is provided between the roller brush chamber (1) and the turbine chamber (2). The clean air current (5) that has passed through the turbine chamber (2) enters the roller brush chamber (1) via the current guiding channel. The roller brush and the turbine are not coaxial. The pneumatic floor brush (130, 230) and the vacuum cleaner (100, 200) solve the problem that a turbine is easily blocked or has a weak load capability, and also the clean air current (5) passing through the turbine is fully utilized, thereby enhancing the cleaning efficiency.</p> |
