Prime Big Deal Days runs October 6-7 — 15 days from today — and the smart-home discounts are the deepest of the fall. But “deep” means different things at different price points. Here is what 2024-2025 event history and current street prices say each budget tier should target, so you know a real deal when you see one.

Tier 1: Under $200 — buy the bundle, skip the flagships

Camera bundles are the play: 2-pack and 3-pack battery cameras (Tapo, eufy) historically drop 25-40%.
Robot vacuums: entry models fall to $150-180 floors; expect little below that.
The rule: at this tier, price floors are shallow — buy only if the item is already near its historical low.

Target examples: Tapo C425 2-pack ~$60-70; budget robot vacuum ~$150-180.

Tier 2: $200-600 — the sweet spot

Mid-range robots get the biggest percentage drops: the Qrevo S class historically hits $379-419 (from ~$500).
Cameras: solar bundles and 2K floodlight cams drop to $80-130.
The rule: this is where waiting for the event actually pays — $100-150 off is normal.

Target examples: Roborock Qrevo S ~$379-399; solar camera bundles ~$80-120.

Tier 3: $600+ — flagship money, flagship drops

Flagship robots drop $150-300: the X50 Ultra class historically touches $899-999 from $1,099-1,299.
Camera systems: NVR bundles and 4K solar flagships see $50-100 off.
The rule: hold your flagship purchase for this window — the Oct 6-7 prices are usually matched only by Black Friday.

Target examples: Dreame X50 Ultra ~$949-999; Reolink 4K solar bundle ~$169-199.

Across Chinese owner communities

The 什么值得买 Prime-window veterans run a simple playbook: “watch-list the SKU now, buy at the floor on day one, skip the second wave.” Day-one prices are almost always the low point — the 3-wave structure mostly restocks the same SKUs, not better prices.

Honest catch

Predictions are history, not promises: last-minute stock and coupons can beat or miss these floors, and some “deals” are bundles with filler accessories. Use the targets as sanity checks — if a flagship robot shows up above $1,000 during the event, it is not the deal of the year.

Bottom line

Set your watch-list now: mid-range robots and solar bundles are the October value plays; flagship robots are the October deep cuts. Check back Oct 6-7 — we will flag the real floors as they drop.
