Abstract
An autonomous surface cleaner for cleaning a floor or other surface. The cleaner may include a body, a cleaning implement for cleaning a surface, a motorized drive system, a pair of wheels operable with the motorized drive system to assist moving the body relative to the surface, one or more actuators operable for controllably adjusting a height of the body, and/or a balancing system operable to self-balance the body.
Claims21
An autonomous floor cleaner, comprising:
- a body;
- a cleaning implement configured for cleaning a floor surface;
- a motorized drive system configured for autonomously moving the body relative to the floor surface;
- a plurality of wheels operable with the motorized drive system;
- one or more actuators configured for controllably raising and lowering the body to selectively adjust a clearance between the body and the floor surface;
- and
- a balancing system operable to self-balance the body.
4 more elements
An autonomous surface cleaner, comprising:
- a body;
- a cleaning implement configured for cleaning a surface;
- a motorized drive system configured for autonomously moving the body relative to the surface;
- one or more actuators configured for controllably actuating the body between at least a first height and a second height;
- and
- a balancing system configured for generating a balance force to selectively influence a center of gravity for the body.
3 more elements
An autonomous surface cleaner, comprising:
- a body;
- a cleaning implement configured for cleaning a surface;
- a motorized drive system configured for autonomously moving the body relative to the surface;
- a plurality of wheels operable with the motorized drive system;
- a balancing system configured for generating a balance force to selectively influence a center of gravity for the body;
- and
- a controller operable to autonomously control the motorized drive system and the balancing system to self-balance the body over the wheels.
4 more elements
An autonomous floor cleaner, comprising:
- a body;
- a cleaning implement configured for cleaning a floor surface;
- a motorized drive system configured for autonomously moving the body relative to the floor surface;
- a plurality of wheels operable with the motorized drive system;
- and
- one or more actuators configured for controllably raising and lowering the body to selectively adjust a clearance between the body and the floor surface;
- wherein the actuators telescope a linkage used to interconnect the wheels with the body, the clearance decreasing as the linkage telescopes inwardly and increasing as the linkage telescopes outwardly.

An autonomous floor cleaner, comprising:
- a body;
- a cleaning implement configured for cleaning a floor surface;
- a motorized drive system configured for autonomously moving the body relative to the floor surface;
- a plurality of wheels operable with the motorized drive system;
- one or more actuators configured for controllably raising and lowering the body to selectively adjust a clearance between the body and the floor surface;
- and
- a controller to autonomously control the motorized drive system and the actuators, wherein the controller adjusts the clearance to a hover height in response to detecting an obstacle protruding above the floor surface, the hover height positioning the body above the obstacle.
