First, planning ability. Planning ability is a reflection of intelligent level of intelligent robot vacuum, which will affect the cleaning ability of intelligent robot vacuum to a large extent. Planning ability test is to simulate the home environment in a 20-inch room, place tables, chairs, cabinets, sofas, household appliances and other items, so that the sample can be automatically cleaned for no more than 30 minutes, and calculate the proportion of the area covered by the cleaning head of the sample to the total area of the room, that is, the coverage rate. The results showed that the highest coverage rate of 22 samples was 90.4%, and the lowest coverage rate was 37.4%.

Samples with strong planning ability mostly cover larger areas through navigation and positioning, building maps and planning routes, so they can be thoroughly cleaned under tables, chairs and other items or behind household appliances. Most of the samples with weak planning ability cannot record areas that have been cleaned, and they are prone to random bombs when encountering obstacles. Open, so it is difficult to penetrate beneath the table, chair and other items or behind the household appliances.

Secondly, the effective clean area of single charge. Because the intelligent robot vacuum usually needs a long charging time, consumers generally expect that the full-charged intelligent robot vacuum can sweep as much area as possible, so as to complete the cleaning of the whole room at one time. This comparative test tested the effective clean area of the sample after single charge, even if the sample was cleaned several times in a room of 20_after full charge until the power consumption was exhausted. The results showed that the effective cleaning area of single charge of 20 samples was 97.6_and 20.2_respectively. The effective clean area of single charging sample with large capacity, low energy consumption and reasonable planning is relatively high.

Then, the effective clean area is charged once. Because the intelligent robot vacuum usually needs a long charging time, consumers generally expect that the full-charged intelligent robot vacuum can sweep as much area as possible, so as to complete the cleaning of the whole room at one time. This comparative test tested the effective clean area of the sample after single charge, even if the sample was cleaned several times in a room of 20_after full charge until the power consumption was exhausted. The results showed that the effective cleaning area of single charge of 20 samples was 97.6_and 20.2_respectively. The effective clean area of single charging sample with large capacity, low energy consumption and reasonable planning is relatively high.
