The Tech Bot is a Power in Bloons TD 6, first released in Version 5.0. It can be purchased in the Powers shop for BloonjaminsIcon50. When placed, a new ability will appear in the side bar, which allows the player to link the Tech Bot to a tower with at least 1 ability. After being linked, the Tech Bot will activate the ability (or abilities) every time it can be used, with no input from the player. In the Contested Territory, it becomes Relic Knowledge, granting up to 1 per game.

Tech Bot can be placed on any land spot and consumes a footprint slightly smaller than a Dart Monkey.


Tech Bot is mainly useful to save the player from micromanaging abilities, but the player has to exercise caution in choosing what ability to link to the Tech Bot. However, there are abilities where it is important to consider linking to:

  • Abilities that generate money (Jungle's Bounty, Monkeynomics, Supply Drop, Support Chinook (do exercise caution with this one if you're using Pursuit), etc.), as these abilities are generally risk-free & tend to get in the way of microing.
  • Overclock (starting in version 16.0) and Ultraboost by Overclocking the latest tower that was targeted. Towers that are Tier 4 or below can be 'permanently' overclocked in this way. For Tier 5 towers or Level 20 Heroes, use two Overclock Engineer Monkeys and activate one another when the other one is on about half of the cooldown.
  • Abilities that only affect a certain type of Bloon (MOAB Assassin/MOAB Eliminator, Monkey Pirates/Pirate Lord, Pat Fusty's Big Squeeze abilities, etc.). Abilities like this will almost never be wasted.
  • Abilities with buffs with nearly 100% full uptime, specifically Pat Fusty's Rallying Roar in water under Energizer and the "Ability Mastery" MK or Admiral Brickell's Naval Tactics under the same other conditions.
  • Abilities that are utilized best with a time-based routine (Bloon Sabotage/Grand Saboteur, Snowstorm/Absolute Zero, Overclocking a tower that are Tier 5, etc.). To utilise these benefits, Tech Bot linkages must be timed promptly with when the activation(s) of when said abilities need to become activated.
    • To further explain, certain abilities have a specific amount of uptime. For instance, Bloon Sabotage has 25% ability uptime because it lasts for 15 seconds but has a cooldown of 60 seconds (therefore 45 seconds downtime).
    • Bloon Sabotage ability needs a minimum of 4 to gain approximately full uptime, so 4 Tech Bots are also required to facilitate this need. The pattern at which Bloon Sabotage abilities activate needn't necessarily always have a ~15 seconds gap, since Bloon Sabotage doesn't soak through all layers, but having more Tech Bots to activate the various Bloon Sabotage abilities are helpful, provided the gap between each Bloon Sabotage isn't too close together (otherwise such abilities will become wasted
      1. Upon the first Tech Bot program to Bloon Sabotage A, the ability for Bloon Sabotage will activate.
      2. Wait for the Bloon Sabotage A to expire and immediately Tech Bot the Bloon Sabotage B, and so on up to Bloon Sabotage D.
    • Overclock ability is simpler. In the worst case scenario, 2 Tech Bots are required for 2 Overclocks in order for the same tower to be always Overclocked. Simply wait for around 20-25 seconds after the Overclock ability is activated, and then activate the Tech Bot onto the other Overclock afterwards.
    • Although other towers may also benefit from multiple Tech Bots at specific timings, only Bloon Sabotage and Overclock are the ones that significantly benefit.

However, abilities with a chance of being wasted, such as Turbo Charge/Perma Charge or Blade Maelstrom/Super Maelstrom, have risks with being linked.

  • As of Version 17.0, the Monkey Knowledge 'Ambush Tech' allows the Tech Bot to activate the linked tower's skill when the Bloon enters a specific track area, allowing some of these abilities to be activated without being wasted.

Note that there are some abilities that never become activated by Tech Bot:

Tech Bot's main use shines on freeplay mode games, where the player will want to achieve higher rounds with little interaction.


  • Placement for Tech Bot does not matter much, as its automatic ability activations are always instantaneous. Therefore, it can be placed on any land location on screen, preferably places that do not block strategically located land spots.

Contested Territory Tips[]

  • Tech Bot as a Relic serves no real purpose other than to automate abilities. It may be better to simply rely on fingers (and also hotkeys if on desktop) to tap/click the abilities rather than use this Relic.
  • If ever needing to use Tech Bot for Contested Territory for whatever reason, strategically use it to automate abilities that need full-on automation, usually cash-generating abilities. For cash-generating abilities, it saves a few seconds of not actually clicking the ability immediately upon end of the cooldown.

Version History[]

  • It used to be possible for Benjamin's Biohack to target Tech Bots. This was no longer the case as of an earlier update.
  • Prior to version 16.0, Overclock could not be targeted by a Tech Bot.
  • On Version 17.0, Dark Knight and its subsequent upgrades earned a new ability to teleport around the map freely. However, activating Tech Bot on any of these towers would have crashed the game.
  • Tech Bots aimed at Heli Pilots always follow the helicopters rather than the bases.
