Abstract
A pool cleaner includes a vent mechanism and a water port in fluid communication with the vent mechanism. When a forward end of the pool cleaner extends above a waterline of the pool, water flows through the vent mechanism and the water port over an inlet port and prevents loss of suction at the inlet port. A protruding member of the pool cleaner contacts submerged obstacle and tilts the pool cleaner to prevent the pool cleaner from becoming stuck on the submerged obstacle.
Claims20
A pool cleaner comprising:
- a drive mechanism operable to drive the pool cleaner along a submerged surface of a pool in a forward direction;
- a housing carried by the drive mechanism, the housing having an inlet port through which water is suctioned;
- an outlet port that receives water from the inlet port;
- a vent mechanism including an opening through a top cover of the housing, the opening being at least partially forward the outlet port, the top cover providing access to an interior of the housing;
- and
- a water port defining at least one opening on a bottom of the housing, the water port receiving water from the vent mechanism when a forward end of the pool cleaner extends above a waterline of the pool so as to prevent loss of suction at the inlet port.

A pool cleaner comprising:
- a drive mechanism operable to drive the pool cleaner along a submerged surface of a pool in a forward direction;
- a housing carried by the drive mechanism, the housing having an inlet port through which water is suctioned and an outlet port that receives water from the inlet port, the inlet port being on a bottom of the housing;
- a forward retractable member extending laterally across the bottom and forward the inlet port;
- a rear retractable member extending laterally across the bottom and rearward the inlet port;
- and
- a protruding member extending downwardly from the bottom and forward between the forward retractable member and rear retractable member;
- wherein when the pool cleaner drives over a submerged obstacle, the protruding member contacts the submerged obstacle and tilts the pool cleaner.
4 more elements
A pool cleaner comprising:
- a housing having an inlet port through which water is suctioned and an outlet port that receives water from the inlet port;
- a first wheel carrying the housing and positioned to contact a submerged surface of a pool, the first wheel having a first wheel gear and a second wheel gear;
- a pinion gear that operably mates with the first wheel gear and second wheel gear, the pinion gear being rotatable about a first rotational axis;
- and
- a drive shaft contactor connected to the pinion gear in such a way that the pool cleaner changes direction when the drive shaft contactor rotates about a second rotational axis offset from the first rotational axis, which moves the pinion gear between the first wheel gear and second wheel gear.
