In-stock merchandise generally ships from our Leesburg, Virginia location within 3–5 business days. Processing time is separate from carrier transit time and is not a guaranteed delivery date. Weekends and holidays can affect timing. Special-order, backordered or unavailable items may take longer; contact us to confirm timing before purchase when a deadline matters.
Shipping options and charges are shown at checkout. After dispatch, follow the carrier's tracking updates. Weather, carrier delays, order verification and inventory confirmation may affect delivery. Inspect packages promptly and retain packaging if there is damage or an incorrect or missing item.
Eligible unused items have a 30-calendar-day return request window for refunds or exchanges, measured from delivery or in-store purchase. Return authorization is required. Final-sale exclusions, the 15% restocking fee for change-of-mind returns and shipping responsibilities are explained in our Return and Refund Policy. That policy is the governing source for return eligibility and fees.
For shipping or return help, email sales@acevacuums.com or call 703-997-9292.
Updated September 27, 2026. Request a return for an eligible unused item within 30 calendar days of delivery (or purchase for items collected in store). Eligible returns may be refunded to the original payment method or exchanged, subject to availability. The same 30-day request window applies to both refunds and exchanges; there is no separate seven-day or 15-day refund deadline.
Items must be unused, clean, complete and in their original packaging with all accessories, manuals and proof of purchase. Contact sales@acevacuums.com or 703-997-9292 before sending anything back. Include your order number, item and reason for return. We will confirm eligibility, charges and return instructions. Unapproved or cash-on-delivery returns are not accepted.
For an approved change-of-mind return, a 15% restocking fee applies to the returned merchandise price. Original shipping charges are not refundable and the customer pays return shipping. These charges do not apply to an approved return caused by our shipping error or a damaged/defective item claim. Contact us first so we can arrange the appropriate remedy and shipping instructions. Do not assume a prepaid label is included.
Air purifiers; discounted, clearance, trade-in, holiday-sale and price-matched purchases; gift cards; custom or special-order products; electrical parts; used or installed items; opened cleaning solutions; and used bags, filters, belts or other consumables are not eligible for change-of-mind returns. Other items clearly marked final sale at purchase are also excluded. An opened box alone does not disqualify an otherwise eligible unused, complete item, but consumables and cleaning solutions must remain unopened.
Inspect your order promptly and contact us as soon as you discover a problem, with your order number and photos where helpful. Keep the packaging. Change-of-mind exclusions and deadlines do not remove applicable defect, warranty, recall or statutory rights. Warranty coverage requires evaluation under the manufacturer's terms; dealer status does not guarantee free repair. Recalled products must follow the manufacturer's recall process.
After we receive and inspect the return, we will notify you of approval or the reason it cannot be accepted. Approved refunds are issued to the original payment method within 10 business days of approval; your bank may take additional time to post them. Contact us if more than 15 business days have passed since approval. Exchanges require authorization and replacement availability; any price difference and applicable charges will be explained before processing.
This policy applies to online and in-store purchases. We will honor more favorable written return terms provided with an earlier purchase. Applicable consumer rights remain unaffected. Where the European Union 14-day cancellation right applies, customers may cancel or return eligible orders within 14 days of receipt, subject to applicable legal exceptions, without giving a reason.
Build your cleaning setup with hoses, tools and care essentials selected by Ace Vacuums. Match the accessory to your wall inlet, hose handle and floor tool before ordering.
A 120 V or 240 V power unit does not identify your hose connection. Electric hoses and brushes need the correct separate electrical connection. Conventional hoses and covers are not replacements for a retractable Hide-A-Hose installation.
Choose a 30 ft or 35 ft Stealth replacement hose. Match direct-connect or corded wall connection and the existing wand and powerhead.
Compact suction-only hose for quick pickups. Fits conventional 1 7/16–1½-inch wall inlets; cannot power an electric brush.
Complete 30 ft pigtail electric kit with 15-inch powerhead. Requires a compatible conventional inlet and nearby electrical outlet.
Keep garage and car-cleaning tools separate. Check your utility valve or inlet and choose 30 ft, 50 ft or no-hose kit.
For hard floors. Fits a standard 1¼-inch round wand; check your wand before ordering.
For stairs, sofas and pet beds. Requires an electric hose with the standard 2-pin handle connector, ⅜ inch apart.
Air-driven brush for stairs and upholstery. Confirm the round hose connection and adequate system airflow.
For furniture and vehicle seats. Match the standard 1¼-inch round hose or wand connection.
For everyday dusting. Match the standard 1¼-inch round hose or wand connection.
Brush for vents, blinds and detail cleaning. Fits a standard 1¼-inch round wand.
Adjustable reach for suction tools. Friction-fit hose end 1⅛–1¼ inches; not an electric powerhead wand.
Pet grooming kit with collection canister. Confirm hose fit and follow the suction-reduction instructions; do not connect directly to a wall inlet.
Protect furniture and baseboards. Select the cover for your 30 ft or 35 ft conventional hose; not for Hide-A-Hose.
Wall storage for a conventional 25–35 ft hose. Choose a color; mounting hardware is not included.
Routine care for central vacuum hoses and pipes. Follow the sheet instructions; persistent blockages need service.
