I purchased my Tineco S12 Plus at Christmas 2019 as a present to myself. I'm a gadget nerd and a clean freak. I have a pretty big home and my home has never been so clean. I love all the extra tools that came with the S12 Plus. I use all of them. I looked at every review I could find and the EXCELLENT HEPA filter was a big deal to me. Every test showed that there is essentially no dust coming out of the filter. The quality build is really good and the trigger lock is something I use every time I vacuum. It's a BIG deal! The auto suction works well and it's nice to be able to adjust the motor speed with the infinite finger slide. It's really nice to have the two batteries although I seldom need the second battery. It's just nice to know I have it (every so often I swap batteries so they both get used). I also like that it comes with two (2) pre-filters. I have a powerful plug in canister vacuum and I use it to quickly clean the pre-filter. I use an EGO electric leaf blower to clean the rest of the dust bin and it's parts. I use NO water. I can clean EVERYTHING and be back vacuuming in 10 minutes. I will mention that the unit I received on Christmas eve malfunctioned after a few days. I contacted Tineco customer service and they were great. They sent me a brand new motor head and a return shipping label so I could send the bad unit back to them. I have been using this replacement for about two months now and it performs perfectly. I use it all the time. I had looked at buying the Dyson V-11 but after using this S12 Plus for about two months now, I am glad I purchased this unit instead of the Dyson. This Tineco is a better value. I don't own a smart phone so I don't have a need to connect my phone to my vacuum. Actually, I think that's a really dumb idea. Everything you need is displayed right on the vacuum head. I currently own nine (9) vacuum cleaners and have owned vacuums for about 50+ years.OK....I've now owned my Tineco for almost 2 years. I love it as much today as when I wrote the above review. I use it several times a week. I use it a lot because it is so easy and convenient to use. My home is really clean all the time. Tineco's customer service is great. Last week one of the small hinge attachments broke on the dust bin. It's plastic. I called Tineco customer service and had a representative on the line in a couple of minutes. I explained my situation. They asked me to send them a photo of the broken hinge. I sent it about an hour later. Within 24 hours, I received a notice that a new dust collector was on it's way to me. I couldn't ask for better service. Thanks Tineco. Sure glad I purchased a Tineco with all the great attachments. Lets see you dust your home, your computer and TV screens with a Dyson!!!!!! 2/04/2023.... I've now had my Tineco for 38 months. I still love it just as much. I just used it a few minutes ago. Thanks Tineco for a really wonderful product!
