They also make cat litter machines and pet feeding machines which you can control with your phone so you can be gone for extended amounts of time while your pet is home alone.
I bought one of those round robotic vacuum cleaners at the local business in my town, so while I am gone in the states, my flat overseas in Europe has clean floors when I return. I can control it with my phone from here in America, which is really cool, and my friends will empty the dustbin once a month for me. It has a HEPA filter in it so it pretty much catches all of the dust that is on the floors. I will be in the states for two months during this visit and I gave my friends the keys to my place over there so that they can check on it to make sure everything is okay there. I am running the HVAC system with my smart wifi thermostat, which I can also do with my phone here. Technology has come a long way and it really helps a lot when you are not going to be home for a while. They also make cat litter machines and pet feeding machines which you can control with your phone so you can be gone for extended amounts of time while your pet is home alone. Not only is my central heat and air conditioning smart phone ready but my lights in the flat can be turned on and off with the phone too. I like this because it looks like I am home when I am gone so that nobody tries to break in and live there or steal things. I’m really happy with the HVAC technology they have out now.
