Key Features:

  1. Interchangeable Bore Inserts: The DYE UL-I Barrel Insert System offers a set of 9 bore inserts with various diameters ranging from .676 to .692. These inserts can be easily swapped within the UL-I barrel system, allowing players to quickly adapt to different paintball sizes and achieve the best possible barrel-to-paintball match. Compatible with barrels that accept the PWR insert system.
  2. Precision-Machined Construction: Each bore insert and barrel component is meticulously machined from high-quality materials to ensure exceptional durability and consistency. The precise tolerances guarantee a tight fit between the insert and the barrel, minimizing air leakage, and maximizing shot consistency.
  3. Enhanced Accuracy: By using the appropriate bore size for the paintballs being used, the DYE UL-I Insert Barrel System significantly improves accuracy. A proper match between the paintball and barrel diameter reduces air turbulence and ensures a straighter trajectory, resulting in more precise shots and increased hit rates.
  4. Air Efficiency: With the ability to fine-tune the bore size, players can achieve optimal air efficiency. The right barrel-to-paintball match minimizes wasted air and ensures consistent velocity, allowing for increased shots per air tank fill.
  5. Quick and Toolless Insert Changes: Switching between different bore inserts is quick and hassle-free, thanks to the toolless design of the DYE UL-I Barrel Insert System. Simply unscrew the barrel from the marker, remove the current insert, and insert the desired one. The secure locking mechanism ensures a snug fit.
  6. Compatibility: The DYE UL-I Barrel Insert System is compatible with a wide range of popular “autococker” threaded paintball markers on the market. It comes in different lengths and threading options to accommodate various personal preferences.

      Rattles like a vibrator when it mops after about 2 weeks.
      Size: C20 renewed
      Works ok. Vacuum beater and opening is only about 6 inches long and the dirt box in the bot is really tiny. Beater is way to tiny to do any real vacuuming on even short shag rugs. The mop works but basically just evenly spreads out whatever dirt is on the floor, evenly across your entire floor and sands the floor with it. After about 2 weeks the bot starts rattling REALLY loud and vibrating like its falling apart. The crazy loud rattling noise is coming from the plastic mop pad axles when they spin. The vacuum bag inside the base is very good quality, but small and not reusable. I cut the far end of the bag down the middle and glued on some velcro strips to each side to re-close it, which allows me to empty the bag and then close it back up again. Pretty sure this thing transmits everything it sees/does back to China.

      Issues
      Size: C20 renewed
      Spent all this money for it to consistently have problems. It doesn’t even mop anymore because it keeps saying there is a problem with the sewage tank. I’ve only turned it on less than 5 times and it’s already having issues. Can’t even get it to mop anymore

      Works great
      Size: C20 renewed
      I saved some money by purchasing this certified like new. Worked well out of the box, but there was an issue with it and the people that do in fact check to ensure these work should do a better job. The issue was with the water and emptying it into the dirty tank. Just kept giving me an error. So, I had to look online for troubleshooting issues. After maybe 20-30 minutes I figured out a tiny little metal piece was loose where the water would have been distributed to. I was able to pop it out and place it back in. After that, and with the right settings selected through the app, everything works great. Well worth it.

      Good mop, bad avoidance
      Size: C20 renewed, Size: C20 renewed
      I have mixed feelings about this product: The good – It does in fact clean very well. The mop picks up dirt effectively and the vacuum works very well. It was also surprisingly good at swapping from carpet to wood. I have a high door mat and it ran right over that. It was also good at mapping rooms and positioning, the floor map and restricted areas worked nicely. App also works well. The bad – Obstacle avoidance, it has none. It will run into everything over and over. If the item is too light (shoes, mic items, etc), it will run up on top of them or push them. It will also get stuck if it runs over something. Cords have no chance. The lidar does not work for anything except a wall, and even there it was unable to deal with short trim (1” trim was too low for the lidar and it kept running into the trim). I was having to run around and ensure there was nothing on the floor for it to work effectively. It also had a lot of trouble with my dining table, it would spend 20 min bumping up against it trying to get everywhere. Overall – this is a great robot mop if your floors don’t have any items on them (or you can restrict any loose items to one area and make it a no-go zone). If that is true then this is a great mop for the price and I would recommend. In practice for me it turned out to be quite annoying due to its limited obstacle avoidance and was almost more of a pain then just using a Swiffer. Note – I had to return because it was making a scraping noise (refurbished version), that is not reflecting in my rating. Though I am also not re-buying due to these issues.
