Float rod seal for vacuum cleaner

A vacuum cleaner comprising:

• a tank having an inlet for receiving liquid material, the tank defining an interior;
• a lid attached to the tank;
• an air impeller housing having an opening in air flow communication with the tank interior, the impeller housing being defined by a space between the motor housing and the lid;
• an air impeller disposed inside the air impeller housing;
• a motor disposed inside a motor housing and operatively coupled to the air impeller;
• a switch having a first position in which power is provided to the motor and a second position in which power to the motor is interrupted;
• a float disposed in the tank;
• a float rod extending between the float and the switch, the float rod being capable of moving the switch from the first position to the second position;
• a boss depending from the motor housing, wherein the lid includes a tube portion having an upper end sized to engage the boss, and a portion of the float rod passes through the tube portion;
• and
• a seal positioned intermediately along the float rod to create a water-tight barrier between opposite ends of the float rod.

A vacuum cleaner comprising:

• a tank having an inlet for receiving liquid material, the tank defining an interior;
• a lid for closing a top of the tank;
• a motor housing attached to the lid;
• a motor disposed inside the motor housing;
• a switch disposed inside the motor housing and having a first position in which power is provided to the motor and a second position in which power to the motor is interrupted;
• an air impeller disposed in an air impeller housing defined by the motor housing and the lid, the air impeller housing having an opening in air flow communication with the interior and the air impeller being operatively coupled to the motor;
• a float disposed in the tank;
• a float rod extending between the float and the switch, the float rod being capable of moving the switch from the first position to the second position;
• and
• a seal supported by the motor housing and attached intermediately along and to the float rod to create a water-tight barrier between opposite ends of the float rod, at least a portion of the seal being adapted to travel with the float rod.
