For the convenience of application, some terms and definitions specified in GB/T 34454-2017 and QB/T 4833-2015 are listed below. 3.1 cleaning robot appliance which may automatically clean the ground without human intervention in a certain area Note: Cleaning robot includes mobile objects, and may contain docking station and accessories. Its run may also be controlled by remote control. [GB/T 34454-2017, 3.1] 3.2 cleaning head air intake at the bottom of robot Note: The width of cleaning head refers to the track of air intake in the direction in which the appliance goes ahead. [GB/T 34454-2017, 3.3] 3.3 docking station base unit unit which provides manual or automatic charging, dust removal from the robot, data processing or other auxiliary functions [GB/T 34454-2017, 3.5] 3.4 navigation and location type cleaning robot cleaning robot that can sense its own position and plan and navigate autonomously, such as cleaning robots with functions of laser positioning navigation, visual navigation or similar functions and their combinations 4 Technical requirements and test methods 4.1 Floor dust removal coefficient 4.1.1 Hard floor linear dust removal coefficient The test shall meet the requirements of linear dust removal test in GB/T 34454-2017, Clause 6, in which the number of runs is changed to 1, that is, single cleaning test includes one run (linear forward movement). The test mode shall be repeatable and simulate the state of normal use, including power, speed and continuous forward mode. The coefficient is graded according to Table 1: Table 1 Grades of hard floor linear dust removal coefficients Grade of hard floor linear dust removal coefficient Limit A Hard floor linear dust removal coefficient ≥ 80% B 70% ≤ hard floor linear dust removal coefficient < 80% C 60% ≤ hard floor linear dust removal coefficient < 70% 4.1.2 Hard floor rectangular frame dust removal coefficient The test shall meet the requirements of rectangular frame dust removal test in GB/T 34454-2017, Clause 5, in which the running duration shall not exceed 5 min. The coefficient is graded according to Table 2: Table 2 Grades of hard floor rectangular frame dust removal coefficients Grade of hard floor rectangular frame dust removal coefficient Limit A Hard floor rectangular frame dust removal coefficient ≥ 85% B 75% ≤ hard floor rectangular frame dust removal coefficient < 85% C 65% ≤ hard floor rectangular frame dust removal coefficient < 75% 4.2 Edge and corner dust removal coefficient The edge and corner dust removal test shall meet the requirements of QB/T 4833-2015, 6.3.3, in which the running duration shall not exceed 5 min. The coefficient is graded according to Table 3: Table 3 Grades of edge and corner dust removal coefficients Grade of edge and corner dust removal coefficient Limit A Edge and corner dust removal coefficient ≥ 70% B 60% ≤ edge and corner dust removal coefficient < 70% C 50% ≤ edge and corner dust removal coefficient < 60% 4.3 Single-room coverage percentage The test method of primary single-room coverage percentage shall meet the test requirements of QB/T 4833-2015, 6.3.1, and only primary coverage percentage is calculated. The coefficient is graded according to Table 4: Table 4 Grades of single-room coverage percentage Product type Cleaning head width Grade of single-room primary coverage percentage A B C Navigation and location type < 150 mm Primary coverage percentage ≥70% 60% ≤ primary coverage percentage < 70% 50% ≤ primary coverage percentage < 60% ≥ 150mm Primary coverage percentage ≥ 75% 65% ≤ primary coverage percentage < 75% 55% ≤ primary coverage percentage < 65% Other types < 150 mm Primary coverage percentage ≥ 65% 55% ≤ primary coverage percentage < 65% 45% ≤ primary coverage percentage < 55% ≥ 150mm Primary coverage percentage ≥70% 60% ≤ primary coverage percentage < 70% 50% ≤ primary coverage percentage < 60% 4.4 Multi-room coverage percentage 4.4.1 General requirements Multi-room coverage percentage is a measure of the robot's capability to cover accessible areas in the standard test room specified in 4.4.2. This test measures the cumulative coverage percentage over a period of time. This test only tests the primary coverage percentage in multiple rooms.
