In general, according to one iXBT.com user, there are no truly square smart vacuum cleaners. There are two reasons for this: It can be attached to furniture, walls, etc. the possibility of the case breaking when struck and the possibility of accidental impact of fragile objects due to the protruding edges of the vacuum cleaner. That is why the edges of such devices are slightly rounded.
If we talk about the advantages of square robotic vacuum cleaners, this is the ability to move it tighter into a corner (the brushes will not reach the walls of the corner by about 1 cm, and for the round one – about 2 cm), a greater number of functions and better characteristics.
However, the robot vacuum cleaner has a few disadvantages. First of all, such models are more expensive than round smart vacuum cleaners with the same features and functions. Secondly, the efficiency and quality of cleaning of such vacuum cleaners in open areas do not differ from their round-body counterparts. In addition, since square robotic vacuum cleaners cannot rotate fully, the device will have difficulty getting out of corners.
Do you want to buy a square robot vacuum cleaner? First, see if it can reach corners. After all, it often makes sense to purchase models with square bodies just for more efficient cleaning of corners.
