When it comes to robot vacuum cleaners, there's one brand that probably springs to mind before any other. But there are plenty of great options out there beyond Roomba, and one of our favorite models is on sale for nearly half off. The Anker Eufy BoostIQ RoboVac 11S Max has dropped to 129, which is a discount of 48 percent or 120. This is our pick for the best ultra budget robot vacuum. Since it has such a deep discount right now, that makes it even more of a budget-friendly recommendation.

Black Friday is a great time to pick up big-ticket items while they're deeply discounted, and robot vacuums fit that bill this year. It's not hard to drop hundreds on an autonomous dirt-sucker at any other time of the year, but Black Friday deals have discounted a bunch of our favorite models. Before snagging a deal, think about the type of home you have and how you'll use the machine: do you have carpet or mostly hard flooring? Do you have pets who shed constantly? Do you want a combo vacuum-and-mop machine?

If you'd like help keeping your floors clean, a robot vacuum is a great way to go -- but they're usually pretty pricy. Right now Amazon is discounting many models of Eufy vacs, with deals up to 51 percent off, putting many of them below the discounts we saw for Black Friday. The biggest call out from the sale is the Eufy RoboVac X8. Both the vacuum-only model and the mop-plus-vac hybrid are on sale. The RoboVac X8 Hybrid is going for $280 instead of its usual $550.

If you've wanted a robot vacuum but were put off by the sometimes-high prices, now's your chance to dive in. Anker's Eufy brand is holding a Black Friday sale on Amazon that includes major discounts for its robotic cleaners, including lower-priced models. The RoboVac 11S Max is down to just $130, or 48 percent off its usual price. One of the company's best devices, the RoboVac X8, has dropped to $300 instead of its usual $500. Other products are typically at least 30 percent off.

Anker's Eufy brand offers some very affordable robot vacuums that just got even cheaper thanks to a sale on at Amazon. The most interesting model is the Eufy BoostIQ RoboVac 11S Max that's available for just $160, for a savings of $90 (36 percent) off the regular price. That's very inexpensive for a model that earned a spot in our budget robot vacuum guide thanks to its attractive looks and super solid design. The RoboVac 11S Max is missing certain features like WiFi connectivity, which isn't surprising given the price. However, it's still easy to control using the physical remote that allows you to set things like cleaning schedules or change the suction power using BoostIQ or Max modes. It cleans both hard and carpeted floors with up to 2,000 Pa of suction power, and is pretty decent at avoiding collisions considering the price.

Spring cleaning has a way of sneaking up on us all, but luckily you can outsource the vacuuming portion of your chores to a semi-autonomous robot. Anker's Eufy brand has a number of solid robot vacuums at various prices, and many of them have been discounted on Amazon. Key among them is the Eufy BoostIQ RoboVac 11S, which is $70 off and down to $160. This model earned a spot in our budget robot vacuum guide thanks to its slim frame and solid cleaning chops. The most important thing to know about the RoboVac 11S is that it does not have WiFi connectivity.

We all could use a little help keeping our homes clean, and now we live in an age where robots are actually capable of lending a (mechanical) hand. Robot vacuums are some of the most ubiquitous smart home gadgets available today with their circular shapes and propensity for bumping into walls. While they provide an undeniable convenience, they can also be expensive. It's not unheard of to drop close to $1,000 on a high-end robo-vac. But in a change from just a few years ago, today there are now plenty of budget robot vacuum options to choose from.

As the holiday weekend approaches, deals on the latest gadgets have been popping up across the web. Apple's 10.2-inch iPad is $30 off right now and Solo Stove, the maker of compact, stainless steel fire pits, has knocked $120 off most of its devices. We even have a few holdouts from Amazon Prime Day still available, like deals on Anker's Eufy RoboVac 11S and a two-pack Nest WiFi system. Here are the best July 4th tech deals we could find. The 10.2-inch iPad remains on sale for $299, or $30 off its normal price.
