The first thing to know is that I have been using one of the original, plug-in (with cord) Bissel Crosswave machines for years. And I like that machine (despite its drawbacks) for what it was. It certainly cleaned my floors more effectively than the prior regimen. But the Bissel suffers from low-quality construction on the internals, deteriorating suction, and was incredibly loud, right from the start (like all Bissel machines, across the board).I’ve watched these floor mopping vacuums improve over time, but not enough for me to spend an additional ~$500 when what I had was good enough. Until now.The Tineco S7 is orders of magnitude better than the legacy (original) Bissel CrossWave. From what I can tell, even the current cordless Bissel CrossWave has not developed their core technology to make it all that different from the original. It is as if the Bissel is an aging and clapped-out Ford sedan, and Tineco rolls up in their new Lexus. Both of those anologous devices are cars, but…eh: That kind of difference.Anyway, two days ago I vacuum-mopped the main/etnry floor hardwood and tile (kitchen, dining room, living room, family room, two baths, den, foyer, and mud room) with the old Bissel Crosswave — using Bissel’s proprietary cleaning solution. Since then, this level has been vacuumed by an iRobot j9 automatic mini vacuum, and once with a Dyson D15 stick vac. A total of about 1900 sf.This morning, after allowing the Tineco S7 to charge overnight, I ran my first vacuum-mopping job, mostly using “Auto” mode, but switching to the “Ultra” (disinfect) mode for the two bathrooms. The automatic assist from the wheels is handy, so long as you do not yank the device around. If the wheels are crossing an already-wet floor, they may fail to register that you have changed directions, and keep spinning the wrong way. But fluid, methodical sweeping is your friend, here. The wheels do work effectively (despite what some reviews may say) when the device is used as designed. Basically: Don’t be a dope.The edge cleaning (especially compared to the Bissel’s non-existence edge cleaning) is superb. Works exactly as advertised, and having *both* sides clean to the edge is very useful. Good design. The biggest difference compared to the Bissel CrossWave? This thing is QUIET, operating somewhere around 63 dB, whereas the corded Bissel CrossWave probably exceeds 100 dB (very loud). The howl that the Bissel produces is, tbh, pretty unpleasant. This Tineco S7 gets high marks for it superbly quiet operation.The Tineco, however, still makes noise, but you can turn that noise off: The “helpful” instructions it blurts out are waaaaay too loud at the default setting; and still too much at their lowest. So that got turned off. The large screen is helpful enough. And that is a large and attractive display that the S7 has, if you are into that kind of thing. The associated app, too, is moderately useful.But back to cleaning. Please refer to the attached pictures and vid to see what *water* (no Tineco cleaning solution used) cleaned up just two days after I had used the Bissel CrossWave; and after two vacuum sweeps by an iRobot and a Dyson. The depicted water is kinda gross, as all these pictures typically are. But then: I’d been walking on that gunk, thinking the floor was clean. It was not.The self-cleaning feature of the Tineco is also very useful (I ran the 2-minute version, not the 6-minute one). The extra roller and filter are ideal, cuz they can be swapped out from the hand-cleaned dirty water receptacle, etc., and the ones you just used allowed to dry. Some have complained that the Tineco can develop odors. This is almost certainly because owners have neglected to maintain and dry the machine after use. So do be aware: There is some very ordinary maintenance required to keep this device in good working condition. Perhaps 10 minutes (at most) after each use.Is this Tineco expensive, even with “Black Friday” deals? Yes, it is. But as I said at the beginning, it is orders of magnitude better in every way than the corded Bissel CrossWave I am moving on from. Just night and day. And the proof is in the pictures.Will it last? Well…there are the batteries, which do not appear consumer-replaceable. That is a concern. Worth noting that 1900 sf + one 2-minute cleaning cycle used 53% of the battery from full. So the larger-than-others capacity of these batteries should see reasonably-good longevity. If it is a concern, buy the extended warranty from Amazon for $50.Other than battery life concerns, everything else seems top notch. There is an issue with how well the used-water tank attaches — distinctly less precise than the snick-snick for the clean water tank. Which is odd. Tineco should address that. But these are just quibbles on what is a very good vacuum-floor-mopping machine that, all in all, should improve your ability to keep a clean house, measurably.
