Abstract

The invention relates to a floor treatment robot having an autonomously movable floor treatment appliance and having a housing. The housing of the floor treatment appliance has a standing area on the top side for supporting a person. At least one load cell is provided. The load cell is suitable for measuring the weight of the person. This floor treatment robot solves the technical problem of reducing the space requirement for different domestic appliances.

Claims

1. A floor treatment robot comprising:

an autonomously movable floor treatment appliance and

a housing, wherein

the housing of the floor treatment appliance comprises a standing area on a top side configured to support a person,

at least one load cell is provided, and

the load cell is configured to measure a weight of the person.

2. The floor treatment robot according to claim 1, wherein

the housing of the floor treatment appliance is suitable for a load of at least 100 kg.

3. The floor treatment robot according to claim 1, wherein

at least three support points of the floor treatment appliance each have a load cell.

4. The floor treatment robot according to claim 3, wherein

bearing points of drive wheels and, where applicable, of freely running castors act as effective points of the load cells.

5. The floor treatment robot according to claim 1, wherein

a base station is provided at least for charging a battery of the floor treatment appliance, and

the base station comprises a base plate configured to receive all support points of the floor treatment appliance, and

the at least one load cell is connected to the base plate.

6. The floor treatment robot according to claim 1, wherein

an evaluation unit is configured to evaluate measurement signals of the at least one load cell.

7. The floor treatment robot according to claim 6, wherein

the evaluation unit measures current dead weight of the floor treatment appliance before the weight of a person standing on it is measured.

8. The floor treatment robot according to claim 6, wherein

a display is arranged in the floor treatment appliance or in a base station.
