Prime Big Deal Days closed at midnight PT – and the most common question in every owner community right now is “I missed the floor, should I wait for Black Friday?” The answer is genuinely model-dependent: some categories will go lower in seven weeks, some will not, and buying the wrong thing now costs more than waiting. This is a 7-week price outlook for robot vacuums and security cameras between PBD and Black Friday 2026 (November 27). Based on how these categories have priced across past event cycles; we do not track live listings.
The short version: flagship robot vacuums and premium cameras go at least as low on Black Friday as they did during PBD – wait. Budget models, accessories, and current-gen mid-tiers rarely beat PBD prices – buy now if you need them.
The 7-week timeline
- Now – mid-October: the post-PBD drift. Flagships snap back $50-150 above their event floors. This is the worst window to buy a flagship – you pay the drift-back price for nothing.
- Late October: early Black Friday previews begin. Ring/Blink/Eero bundles and accessories start dipping before the main event – the signal that the seasonal lows are coming.
- First two weeks of November: the pre-Black-Friday wave. Budget models and last-gen flagships (S8 MaxV Ultra, older X-series) hit their seasonal lows here, often before Black Friday itself.
- Black Friday week (Nov 23-27): the main event. Flagship robot vacuums and premium cameras reach their yearly floors – historically at or below PBD levels, with the same models cycling in Lightning-deal waves.
What to wait for (Black Friday will match or beat PBD)
- Flagship robot vacuums: Qrevo Curv, Qrevo Master, Saros 10R, Dreame X50 Ultra, eufy X10 Pro Omni – the models that hit $799-1,099 floors at PBD have returned to those floors every Black Friday for the last three years. Wait.
- Premium cameras: Ring Floodlight Cam Pro, Arlo Ultra 2, eufy S340 – premium camera lines discount at or below PBD levels during Black Friday week. Wait.
- Anything that sold out during PBD: if you missed a floor, Black Friday is the scheduled second chance – the same model, the same or lower price, no third-party markup needed.
What to buy now (PBD was the floor)
- Accessories and consumables: filters, dust bags, mop pads, sensors – these hit their PBD floors and typically do not go lower at Black Friday. If you need them, today’s price is the price.
- Budget robot vacuums under $300: budget lines (Wyze, Tapo RV series, eufy 15C Max) did not get meaningfully cheaper at Black Friday in recent cycles – the PBD price was the seasonal floor. Buy now.
- Amazon-brand bundles: Ring/Blink/Eero actually discount hard on PBD Day 2 AND Black Friday – the two events are usually tied. If you missed Day 2, Black Friday matches it; if you bought Day 2, you are done.
Across Chinese owner communities
Cross-border shoppers on Xiaohongshu run both events every year, and their seasonal playbook matches this outlook precisely. The community line on PBD-vs-Black-Friday: “黑五和会员日价格基本持平,旗舰等黑五,配件马上买” (Black Friday and Prime Day prices are basically equal – wait on flagships, buy accessories now). Their warnings are specific: flagships return to their floors every Black Friday, so paying the drift-back price in October is the one mistake everyone calls out; and third-party markups on sold-out models are never worth it – the scheduled restock is always coming. The consensus for the next seven weeks: set your floor list, watch the late-October preview wave, and hold for Black Friday week.
The honest catch

The wait-for-Black-Friday advice has three honest exceptions. First, stock risk: the most popular models (Qrevo Curv, eufy X10 Pro Omni at their floors) sell out fast on Black Friday too – if you can tolerate the risk, wait; if a sold-out event would annoy you more than $50, buy at a modest above-floor price now. Second, the floor is not guaranteed on every model: last-gen flagships and niche models sometimes hit their seasonal lows in the pre-Black-Friday wave instead – the late-October preview is when to watch, not November 27 itself. Third, the exact same model at Black Friday is not always the exact same listing: manufacturers rotate SKUs, and a “newer” version at the same price can quietly lack a feature you wanted – check the SKU before you celebrate the floor. For the mainstream flagships, the wait is safe; for the edge cases, watch the preview wave.
Bottom line
Between now and Black Friday (November 27), the buying rule is simple: flagships and premium cameras wait for Black Friday week – the floors return at or below PBD levels, and the late-October preview wave tells you when. Accessories, budget robots, and consumables buy now – PBD was their floor and it will not go lower. Your floor list from the PBD coverage is still the only authority: log the targets, ignore the drift-back prices, and hold until the preview wave starts. The floors come back – they always do.
