Particular requirements for rechargeable battery-operated commercial robotic floor treatment machines with traction drives

This clause of Part 1* is replaced by the following. 

* For the purposes of this Standard, the term Part 1 means CAN/CSA-C22.2 No. 60335-1 (second edition)/ UL 60335-1 (sixth edition). 

The machines covered in this Standard are intended for floors with an artificial surface and used for the following applications: 

a) sweeping; 
b) scrubbing; 
c) wet or dry pickup; 
d) polishing; 
e) application of wax, sealing products, and powder-based detergents; and 
f) shampooing. 

Their cleaning motion is more linear than lateral or periodic. 

This Standard deals with the safety requirements of rechargeable battery-operated commercial robotic floor treatment machines with traction drive intended for indoor use in accordance with CSA C22.1, Canadian Electric Code, Part I, in Canada, and with the National Electrical Code, NFPA 70 in the U.S., the rated voltage of the battery being not more than 75 V dc. 

NOTE 101 Commercial uses are, for example, in hotels, schools, hospitals, factories, shops, warehouses, and offices for other than normal housekeeping purposes. 

This Standard covers machines that are powered by rechargeable batteries that are recharged by built-in battery chargers or off-board battery chargers which may be incorporated within the circuitry of the machine, or mounted on the machine and incorporated within the enclosure of the machine; or powered by batteries that need to be removed to be recharged with a charger that is external to the machine. 

NOTE 102 When the term machine is used in this Standard, it is used to denote commercial robotic floor treatment machines. 

This Standard does not apply to battery chargers. Off-board chargers are covered by separate applicable standards (see CSA C22.2 No. 107.1, CAN/CSA-C22.2 No. 107.2, CSA C22.2 No. 223, CAN/CSA-E60335-2-29, UL 1012, and UL 1310). 

This Standard covers the safe functioning of lithium-ion and non-lithium-ion battery systems used in commercial robotic floor treatment machines. 

Machines covered by this Standard may operate in autonomous or manual mode. 

This Standard does not apply to 

• machines designed for use on slopes with a gradient exceeding 20%; 
• machines designed for use in corrosive or explosive environments (i.e., dust, vapour, or gas); 
• machines designed for picking up hazardous dusts (as defined in CAN/CSA-E60335-2-69), inflammable substances, or glowing particles; 
• powered ride-on and powered walk-behind machines intended for commercial indoor or outdoor use (those machines are covered by CAN/CSA-C22.2 No. 60335-2-72/UL 60335-2-72); and 
• machines with robotic arms (end effectors).
