| Expense Narrative [Text Block] | oef_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

| Expense Example Narrative [Text Block] | oef_ExpenseExampleNarrativeTextBlock | This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.
The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. This example does not include brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:

| Portfolio Turnover [Heading] | oef_PortfolioTurnoverHeading | Portfolio Turnover. | ||||||||||||||||||||||||||||
| Portfolio Turnover [Text Block] | oef_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 75% of the average value of its portfolio.

Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index, which is designed to provide exposure to U.S. investment grade bonds having the highest “quality scores” as determined by the Index Provider using its methodology described below. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”). In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of all U.S. dollar-denominated bonds issued by U.S. companies. To be eligible for inclusion in the Underlying Index, bonds must (i) have an average credit rating that is higher than BBB- (or equivalent), as derived from ratings by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), Fitch Ratings Inc. (“Fitch”) and Moody’s Investors Service, Inc. (“Moody’s”) credit rating agencies; (ii) have at least $600 million in face value outstanding, with only the largest bond from each issuer eligible; (iii) have at least two years, and no more than ten years, until final maturity; and (iv) make coupon payments. Qualifying securities include: fixed rate, bullet bonds, sinking funds, amortizing, puttable, extendable, callable, and step-up bonds with schedules known at issuance. Securities issued in accordance with Rule 144A (“Rule 144A securities”) under the Securities Act of 1933, as amended (the “Securities Act”), bonds registered with the Securities and Exchange Commission (“SEC”), publicly underwritten medium-term notes and Eurodollar bonds are all eligible for inclusion in the Underlying Index.
The Index Provider assigns a quality score (“Quality Score”) to each eligible bond, which is calculated based on such bond’s maturity and credit rating. With respect to the maturity factor, each bond is scored based on the number of years remaining to maturity, with bonds having fewer years to maturity receiving higher scores. With respect to the credit rating factor, each rating agency’s rating is converted into a numerical value and a bond’s credit score is calculated as an equally-weighted average of the numerical scores of each agency that has rated the bond. The maturity and credit scores for each bond are standardized across the universe of eligible bonds, and the Quality Score for each bond is computed as an equally-weighted combination of these two factors.
All eligible securities are ranked by Quality Score. Initially, bonds with Quality Scores in the top 40% of eligible securities are selected for inclusion in the Underlying Index. At each monthly rebalance, any new eligible security with a Quality Score in the top 30% of eligible securities is added to the Underlying Index, and current Underlying Index constituents with a Quality Score in the top 50% of eligible securities remain in the Underlying Index, provided that they satisfy all other eligibility criteria. Underlying Index constituents are equally weighted. The Underlying Index is rebalanced each calendar month. At that time, the set of eligible securities is determined, securities are selected for membership in the Underlying Index, and the Underlying Index is reweighted. As of October 31, 2024, the Underlying Index was comprised of 154 constituents. The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective. Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of August 31, 2024, the Fund had significant exposure to the financials sector. The Fund’s portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time.

| Invesco Investment Grade Defensive ETF | Market Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Additionally, natural or environmental disasters, widespread disease or other public health issues, war, military conflicts, acts of terrorism, economic crises or other events could result in increased premiums or discounts to the Fund’s net asset value (“NAV”). | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Index Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, the Fund would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Underlying Index, and, therefore, any changes to the Underlying Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Fixed-Income Securities Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may occur quickly and without advance warning following sudden market downturns or unexpected developments involving an issuer, and which may adversely affect the liquidity and value of the security. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Changing Fixed-Income Market Conditions Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Changing Fixed-Income Market Conditions Risk. Fluctuations in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed-income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed-income investments, particularly those with longer maturities, when rates increase. Such changes and resulting increased volatility may adversely impact the Fund, including its operations and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund's investments and share price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets. This could result in higher than normal redemptions by APs (as defined herein), which could potentially increase the Fund’s portfolio turnover rate and transaction costs. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Industry Concentration Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources; adverse labor relations; political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or industry group may be out of favor and underperform other industries or the market as a whole. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Financials Sector Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financials sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Changes in interest rates can have a disproportionate effect on the financials sector, and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Rule 144A Securities Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such, Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. Delay or difficulty in selling such securities may result in a loss to the Fund. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Call Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercises such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Reinvestment Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Reinvestment Risk. Reinvestment risk is the risk that the Fund will not be able to reinvest income or principal at the same return it is currently earning. Reinvestment risk is greater during periods of declining interest rates, as prepayments often occur faster. It is related to call risk, since issuers of callable securities with high interest coupons may call their bonds before their maturity date. This may require the Fund to reinvest the proceeds at an earlier date, and it may be able to do so only at lower yields, thereby reducing its return. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Liquidity Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Issuer-Specific Changes Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Sampling Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Sampling Risk. The Fund's use of a representative sampling methodology may result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Non-Correlation Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. Additionally, the Fund's use of a representative sampling approach may cause the Fund not to be as well correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Authorized Participant Concentration Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, and Shares may be more likely to trade at a premium or discount to the Fund's NAV and to face trading halts and/or delisting. Additionally, investments in non-U.S. securities may have lower trading volumes or could experience extended market closures or trading halts. To the extent that the Fund invests in non-U.S. securities, it may face increased risks that APs may not be able to effectively create or redeem Creation Units, or that the Shares may be halted and/or delisted. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Market Trading Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's NAV. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Operational Risk [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks. | ||||||||||||||||||||||||||||
| Invesco Investment Grade Defensive ETF | Shares May Trade at Prices Different than NAV [Member] | ||||||||||||||||||||||||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||||||||||||||||||||||||
| Risk [Text Block] | oef_RiskTextBlock | Shares May Trade at Prices Different than NAV. Shares trade on a stock exchange at prices at, above or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. | ||||||||||||||||||||||||||||
