Yes anything is possible but at what cost.
- weight. To clean deep like you must put on long brush heads, these will make the Robovac ride on top of the pile, not actually clean, unless you make it heavier to sink into the pile.
- the weight would have to increase for the motor to overcome the higher resistance from brushing through more pile.
- the weight would have to increase for bigger battery to feed the bigger more.
So pretty much as the pile scales so does the Robovac. It becomes larger at least in height but probably width. If you make it wider it can’t clean in corners so well, so would tend to focus on being taller.
The heavier and more powerful item would then NOT do so well on everything else as the longer brush on other things like shallow pile, lino, wood, would tend to “walk tall” and the skirt would be high so you’d not get suction and so basically be spraying dirt around.
So you’d then need to make the brushes retract to adjust their height and sense.
You’d then hit issues with safety as the more powerful heavier retracting would kind of murder a small animal, pull a cat’s leg paw off, and be more expensive.
